Revision Notes đź“š
Environmental approaches and international agreements A-Level Politics revision
The Edexcel specification requires you to understand competing approaches to global environmental problems and the strengths and weaknesses of major international agreements.
The required content includes:
shallow-green ecology
deep-green ecology
sustainable development
tragedy of the commons
key highlights from Rio
Kyoto
Copenhagen
Paris.
These ideas deal with two connected questions:
How radically must human behaviour and economic development change to protect the environment?
Can sovereign states co-operate effectively enough to achieve those changes?
The first question creates the shallow-green versus deep-green debate.
The second leads to sustainable development, the tragedy of the commons and international environmental agreements.
Shallow-green ecology
Shallow-green ecology argues that environmental problems can be addressed without completely transforming existing economic and social arrangements.
Pearson's 2024 mark scheme identifies several important characteristics:
economic growth can continue, although potentially at a slower pace
shallow ecology is based on enlightened anthropocentrism
existing lifestyles and consumption patterns do not necessarily have to be fundamentally abandoned
environmental problems may be tackled through green capitalism
technological, economic and political reforms can therefore be used within broadly existing structures.
Enlightened anthropocentrism
An anthropocentric approach is human-centred.
The Edexcel specification defines anthropocentrism as a view in which the non-human world is understood in terms of its value to human beings.
Shallow ecology is more accurately described as enlightened anthropocentrism because it recognises that humans have environmental responsibilities and that environmental degradation can ultimately damage human wellbeing.
The basic argument is:
humans depend on the environment
↓
environmental damage threatens human interests
↓
humans therefore have good reasons to protect the environment
Shallow ecology does not need to argue that nature must always take priority over human needs.
Shallow ecology and economic growth
One of the most important examination distinctions concerns growth.
Shallow-green ecology accepts the possibility of continued economic development.
Its supporters can therefore argue that environmental protection does not require the complete rejection of:
markets
technological development
industrial production
economic growth.
This fits with green capitalism, which Edexcel defines as the belief that markets can deliver environmental solutions through technology and the response of capitalism to environmentally aware consumers.
The appeal of this approach is political as well as environmental.
Governments may find gradual environmental reforms more acceptable than policies requiring radical reductions in consumption or living standards.
Strengths of shallow-green ecology
A shallow-green approach may be considered attractive because it is comparatively pragmatic.
It attempts to reconcile:
environmental protection + economic development
rather than treating them as completely incompatible.
This may make environmental policies easier for governments and populations to accept.
Pearson's 2024 material indicates that deep-green policies could have a much greater impact on consumption and therefore face stronger resistance, particularly in developed societies. This provides an indirect strength for shallow ecology: less radical change may be politically easier to achieve.
Weaknesses of shallow-green ecology
Deep-green critics argue that shallow ecology does not go far enough.
If environmental degradation is caused partly by:
continuous economic growth
high consumption
industrialisation
heavy use of finite resources
then attempting to preserve those systems may deal only with the symptoms rather than the causes.
Pearson's mark scheme notes the criticism that shallow ecology can amount to protecting the lifestyles of populations in developed states rather than creating the radical environmental changes required.
This creates a key evaluation:
Political realism may make shallow ecology easier to implement, but environmental moderation may also make it insufficient.
Deep-green ecology
Deep-green ecology calls for a much more radical change in the relationship between human beings and the natural environment.
Pearson identifies deep ecology with:
ecocentrism
a much more radical challenge to economic growth
reduced use of non-renewable resources
more localised production
criticism of consumerism and materialism
significant changes to existing economic arrangements.
Deep ecology therefore argues that environmental problems cannot be solved simply by making capitalism or industrial society slightly greener.
The underlying values of society must change.
Ecocentrism
Ecocentrism is a nature-centred rather than human-centred system of values that gives priority to ecological balance.
This creates a fundamental difference from shallow ecology.
A shallow ecologist asks:
How can the environment be protected so that human society can continue successfully?
A deep ecologist asks:
How must human society change in order to respect the value and balance of the natural world?
The second approach places much less emphasis on human interests as the automatic priority.
Deep ecology and economic growth
Deep ecology is much more sceptical about continued economic growth.
Pearson's 2024 mark scheme states that deep ecology requires a much more radical re-evaluation of capitalism and is associated with changes to production, opposition to industrialisation, reduced emphasis on growth and rejection of materialism.
This creates a much more demanding environmental programme.
Possible changes include:
reducing consumption
reducing reliance on non-renewable resources
increasing localised production
challenging materialism
questioning continued industrial expansion.
This approach links to the idea of limits to growth, which reflects the principle that a finite Earth places limits upon unlimited industrial growth.
Strengths of deep-green ecology
The main strength is that deep ecology attempts to address what it sees as the underlying causes of environmental degradation.
If continual consumption and industrial expansion are central causes of environmental damage, then radical changes to those systems might produce a greater environmental effect than gradual reform.
Pearson's 2024 mark scheme accepts the argument that deep-green proposals may produce a more immediate environmental impact and could increase the likelihood of meeting international environmental targets.
Deep ecology therefore offers a powerful critique of the assumption that continual economic expansion and serious environmental protection can always be reconciled.
Weaknesses of deep-green ecology
Its radicalism is also its major political weakness.
Deep-green policies could significantly affect:
consumption
production
economic growth
established lifestyles.
This is particularly important in developed states where high levels of consumption are deeply embedded.
Pearson's 2024 mark scheme notes that deep-green proposals may therefore face greater public resistance.
This creates another useful judgement:
Deep ecology may demand changes capable of producing greater environmental effects, but those same changes may be much harder to secure politically.
Shallow-green and deep-green ecology compared
This comparison was directly assessed by Edexcel in the 2024 Paper 3B examination.
Issue | Shallow-green ecology | Deep-green ecology |
Basic outlook | Environmental problems can be addressed through reform | Environmental problems require radical change |
Human relationship with nature | Enlightened anthropocentrism | Ecocentrism |
Economic growth | Can continue, although potentially more slowly | Requires a much more fundamental challenge to growth |
Capitalism | Green capitalism can provide solutions | Existing capitalist and industrial structures are part of the problem |
Consumption | Fundamental transformation not necessarily required | Consumerism and materialism must be challenged |
Production | Existing systems can be adapted | Greater localisation and major change are required |
Political feasibility | More moderate and potentially easier to implement | More radical and likely to face greater resistance |
Potential environmental impact | Gradual | Potentially more rapid and far-reaching |
đź“Ś Exam tip:Â Do not write one paragraph explaining shallow ecology and another explaining deep ecology. Make the comparison directly:
"Whereas shallow ecologists..., deep ecologists..."
That structure naturally produces the comparative AO2 required by a 12-mark Paper 3 question.
Sustainable development
Sustainable development is defined by Edexcel as:
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
This concept tries to bring together two objectives that can appear to conflict:
development
environmental protection.
Sustainable development does not necessarily demand the end of all economic development.
Instead, it asks whether present development can occur in a way that preserves the capacity of future generations to meet their needs.
Present needs versus future needs
The central idea involves a relationship across time.
If the current generation consumes resources in a way that destroys the ability of future generations to use them, development is not sustainable.
A useful chain is:
present economic activity
↓
use of environmental resources
↓
possible environmental depletion
↓
reduced opportunities for future generations
Sustainable development attempts to prevent that final outcome.
Sustainable development and shallow ecology
Sustainable development can fit particularly easily with the shallow-green belief that environmental protection and continued development can be reconciled.
A shallow-green response may therefore ask how:
growth can become greener
resources can be used more carefully
environmental damage can be reduced
economic development can continue in a more sustainable form.
This is not the only possible interpretation of sustainability, but it demonstrates why shallow-green thinking is often more compatible with continuing economic development.
Sustainable development and deep ecology
Deep-green thinkers are much more sceptical about whether conventional ideas of continued development can genuinely become sustainable.
If the underlying economic model depends upon:
continual growth
increasing consumption
industrial expansion
then simply attaching the word "sustainable" may not solve the environmental problem.
Deep ecology therefore places greater emphasis on changing the fundamental relationship between humans, consumption and nature.
This creates a useful exam debate:
Is sustainable development a genuine solution to environmental degradation, or does it allow existing patterns of growth to continue under a greener label?
The global commons
The tragedy of the commons is easiest to understand after defining the global commons.
Edexcel defines global commons as:
Areas and resources that are un-owned and consequently beyond national jurisdiction.
The political problem is that shared resources are not controlled exclusively by one individual state.
This means states or other actors may benefit personally from using the resource while the environmental costs are spread among everyone.
The tragedy of the commons
Edexcel defines the tragedy of the commons as a situation in a shared-resource system where individual users, acting independently and rationally according to their own self-interest, behave contrary to the common good by depleting the shared resource.
This is one of the most useful concepts in Global Politics because it helps explain why international environmental co-operation is difficult.
How the tragedy of the commons works
Imagine a shared environmental resource.
Each actor faces a choice:
limit its own use of the resource
continue using as much as possible.
If an actor limits itself while everybody else continues using the resource heavily, that actor may suffer an economic disadvantage without preventing environmental damage.
The apparently rational choice is therefore to keep exploiting the resource.
If everybody makes the same decision:
individual rational self-interest
↓
continued exploitation
↓
collective environmental damage
↓
every actor ultimately loses
That is the tragedy.
States and the tragedy of the commons
The concept can be applied to sovereign states.
A government may recognise that environmental protection requires collective restraint but still worry that environmental restrictions could:
slow its economic growth
raise costs
reduce competitiveness.
It may therefore prefer other states to make the expensive environmental changes first.
If many governments reason in this way, collective progress becomes slow.
This connects directly to the next lesson on sovereignty and international disagreement [Obstacles and non-state actors].
The tragedy of the commons and realism
The concept can support aspects of the state-centred approach [Realism].
Realists emphasise sovereign states pursuing their own interests within an international system lacking a superior world government.
From this perspective:
states are responsible for protecting national interests
governments cannot be certain other states will co-operate
environmental agreements may therefore be weakened by self-interest.
The tragedy of the commons illustrates why individually rational state behaviour can produce an environmentally damaging global outcome.
The tragedy of the commons and liberalism
A liberal response is more optimistic.
International co-operation [Liberalism] can create institutions and agreements that make collective environmental action easier.
International agreements may:
establish shared expectations
encourage repeated co-operation
reduce uncertainty
create common targets
provide mechanisms through which states respond collectively.
The Rio, Kyoto, Copenhagen and Paris processes can therefore be interpreted as attempts to overcome the tragedy of the commons through global governance.
International environmental agreements
Edexcel requires the strengths and weaknesses of international agreements and identifies four particularly important examples:
Rio
Kyoto
Copenhagen
Paris.
The agreements demonstrate the increasing importance of environmental issues within global politics.
Pearson's mark schemes note the significant growth in major environmental conferences, particularly Kyoto in 1997, Copenhagen in 2009 and Paris in 2015.
However, the existence of an agreement does not prove that environmental governance has succeeded.
For every agreement, think about two separate questions:
Did states reach an agreement?
and
Did the agreement create sufficiently effective action?
Rio Earth Summit, 1992
The Rio Earth Summit in 1992 is a foundational moment for the environmental governance covered by the specification.
The most important testable highlight supported directly by the Edexcel material is that the United Nations Framework Convention on Climate Change (UNFCCC)Â was negotiated at Rio.
The detailed role of this institution is covered in the UNFCCC and IPCCÂ [Global environmental governance].
Strengths of Rio
1. It established an international framework
Rio contributed to the development of the UNFCCC, creating a structure through which international climate negotiations could continue.
This matters because environmental problems could now be addressed through an established process rather than occasional, isolated diplomatic action.
2. It recognised climate change as a global political issue
The development of an international environmental treaty demonstrated increasing recognition that environmental problems require co-operation among states.
3. It laid foundations for later agreements
The later Kyoto, Copenhagen and Paris processes developed within the wider system of international climate governance that followed Rio.
Rio's significance can therefore be measured partly by the continuing international process it helped establish.
Weaknesses of Rio
The creation of a framework does not itself guarantee environmental action.
International environmental governance remains largely intergovernmental, so agreements continue to depend heavily upon sovereign governments.
Rio therefore helped create the process, but the effectiveness of that process remained dependent upon later agreements and state implementation.
Kyoto, 1997
The Kyoto conference took place in 1997 and was a major development in international environmental governance.
Pearson materials identify:
binding targets
emissions reductions
cap and trade
carbon trading
carbon sinks
as relevant features when discussing Kyoto.
Pearson's 2022 mark scheme also notes that Kyoto established long-term commitments, with its 1997 targets set at the time for 2012.
Strengths of Kyoto
1. It moved towards specific commitments
Kyoto represented more than general recognition that environmental degradation was a problem.
The use of emissions targets gave states clearer commitments.
2. Binding targets increased the seriousness of the agreement
Pearson examiner feedback specifically recognises accurate knowledge of Kyoto's binding targets and emissions reductions as useful examination material.
This distinguishes Kyoto from environmental governance based only upon declarations of intent.
3. It developed mechanisms intended to make reductions more achievable
Cap-and-trade and carbon trading mechanisms attempted to reconcile environmental objectives with existing economic systems.
This can be interpreted as a relatively shallow-green approach because environmental targets are pursued without entirely rejecting markets.
Weaknesses of Kyoto
1. Carbon trading and carbon sinks attracted criticism
Pearson materials identify controversial carbon sinks and carbon trading as mechanisms that could allow states greater flexibility rather than requiring direct reductions.
Critics may therefore argue that flexibility weakens environmental effectiveness.
2. Commitments were long term
Targets established in 1997 for 2012 demonstrate how international environmental agreements can delay major changes over a lengthy period.
This is particularly important from a deep-green perspective, which favours more radical and immediate change.
3. Enforcement remained difficult
Even apparently binding international commitments operate within a system of sovereign states.
International environmental governance lacks the same degree of direct enforcement available within a sovereign state.
Copenhagen, 2009
The Copenhagen climate conference took place in 2009.
Pearson identifies Copenhagen as one of the major environmental conferences involved in setting global targets and as evidence of the increasing prominence of environmental governance.
Pearson's 2022 materials also refer to promises of economic support made through international conferences including Copenhagen.
Strengths of Copenhagen
1. It continued the process of global negotiation
The fact that major states continued meeting demonstrates that environmental governance had become a persistent rather than temporary feature of global politics.
2. It maintained global environmental targets
Pearson groups Copenhagen with Kyoto and Paris as major conferences setting global targets.
3. It recognised the economic dimension of environmental co-operation
Promises of financial support demonstrate recognition that environmental action and economic inequalities are connected.
This becomes especially important when studying developed and developing states [Obstacles and non-state actors].
Weaknesses of Copenhagen
Pearson's materials repeatedly criticise environmental agreements for:
vague commitments
voluntary elements
limited punishment
opportunities for states to avoid firm targets.
Copenhagen illustrates the wider problem that agreement may be achieved partly because governments retain significant flexibility.
This creates a trade-off:
more flexibility may encourage more states to participate
but
more flexibility may produce weaker environmental action
Paris, 2015
The Paris agreement followed in 2015, continuing the process of international climate governance.
Pearson's 2023 mark scheme presents Paris as evidence of extremely broad international support. It notes that, as of early 2021, all 197 UNFCCC states had signed or acceded to the Paris Treaty, including China and the United States.
This historical figure is useful because it demonstrates how widely environmental concerns had become accepted within the international community.
Strengths of Paris
1. Very broad participation
Environmental problems are global, so participation matters.
An agreement involving an extremely wide range of states is more capable of addressing a shared environmental problem than an agreement involving only a small group.
2. It demonstrated widespread recognition of climate change
Pearson's 2023 material argues that UN member states have broadly recognised climate change as a serious threat and accepted the need to limit emissions.
That represents a major achievement in global agenda-setting.
3. It continued environmental governance beyond previous conferences
Paris demonstrates that international environmental governance did not end with Rio, Kyoto or Copenhagen.
Repeated conferences create an ongoing process through which states continue attempting to co-operate.
Weaknesses of Paris
1. State sovereignty still matters
International participation does not eliminate the ability of individual governments to alter their policies.
Pearson mark schemes use the Trump administration's decision to reject or withdraw from the Paris process as an example of how environmental co-operation can be affected by changing national political leadership.
The important exam point is the vulnerability of international environmental agreements to domestic state decisions.
2. Commitments can lack strong enforcement
Pearson's materials criticise international environmental agreements where commitments are voluntary and where no strong punishment exists for failure to meet them.
Broad participation can therefore come at the cost of stronger compulsory action.
3. Financial promises can be disputed
Pearson's 2022 mark scheme identifies criticism that relatively little of the promised support for developing countries had been provided.
This can undermine trust between developed and developing states.
Rio, Kyoto, Copenhagen and Paris compared
Agreement | Key highlight supported by Pearson materials | Main strength | Main weakness |
Rio, 1992 | UNFCCC negotiated at the Earth Summit | Established an international framework for climate governance | Framework depended upon later state co-operation and implementation |
Kyoto, 1997 | Global emissions commitments, including binding targets and market mechanisms | Introduced clearer commitments and emissions reductions | Carbon trading, carbon sinks and long timescales could weaken direct action |
Copenhagen, 2009 | Major international conference setting environmental targets | Continued global negotiations and recognised economic support issues | Commitments could be vague and difficult to enforce |
Paris, 2015 | Very broad international participation and continued global targets | Demonstrated widespread acceptance of the need for international climate action | State sovereignty, flexible commitments and weak enforcement can limit implementation |
What do the agreements show about global environmental governance?
Taken together, the four agreements show a clear development:
Rio
creates an international framework
↓
Kyoto
develops more specific environmental commitments
↓
Copenhagen
continues major global negotiation
↓
Paris
achieves extremely broad international participation.
This development demonstrates the increasing significance of environmental governance.
Pearson examiner feedback has repeatedly recognised the growing number and coverage of international environmental conferences as evidence that environmental issues have become increasingly prominent in global politics.
Why more agreements do not necessarily mean greater effectiveness
A common examination mistake is to argue:
more conferences = environmental problem solved
This is too simplistic.
The agreements demonstrate significant political attention and co-operation, but environmental effectiveness depends upon what states subsequently do.
Pearson's 2023 examiner report noted that candidates often recognised almost universal commitment to tackling environmental degradation but correctly contrasted this with the perceived inadequacy of state action.
A better chain is:
more international agreements
↓
greater recognition and co-operation
↓
potential for collective action
↓
but implementation still depends upon states
Therefore:
international governance can be politically successful without being fully environmentally successful.
Shallow-green thinking and international agreements
International climate agreements can often be interpreted as broadly compatible with shallow-green thinking.
They generally attempt to make the existing international economic system more environmentally sustainable rather than replacing it completely.
Kyoto's carbon trading mechanisms are especially useful here.
They seek to use market-based arrangements to achieve environmental outcomes.
This resembles shallow-green faith in green capitalism and reform.
Deep-green criticism of international agreements
Deep-green ecology offers a much more radical criticism.
If the underlying causes of environmental damage are:
continual economic growth
industrial production
consumerism
materialism
high use of non-renewable resources
then agreements that allow those systems largely to continue may be insufficient.
Pearson's 2024 mark scheme explicitly recognises the argument that deep-green policies may achieve environmental treaty targets more rapidly than shallow-green approaches.
The deep-green criticism is therefore:
international agreements may be too shallow-green to resolve a problem requiring deep-green change.
The tragedy of the commons and international agreements
International agreements can also be understood as attempts to solve the tragedy of the commons.
Without co-operation:
each state pursues its own interests
↓
each prefers others to bear environmental costs
↓
shared environmental resources continue to be damaged
International agreements attempt to change this by establishing collective commitments.
However, if agreements lack enforcement, the underlying tragedy remains.
States may still calculate that short-term national economic advantages are more valuable than fulfilling demanding environmental promises.
Sustainable development and the agreements
Sustainable development provides another way of understanding Rio, Kyoto, Copenhagen and Paris.
The agreements attempt, in different ways, to make present development compatible with longer-term environmental needs.
This makes sustainable development politically appealing because it avoids presenting the choice simply as:
economic development OR environmental protection
Instead it aims for:
economic development AND environmental sustainability
The difficulty is whether those two objectives can genuinely be reconciled.
That is precisely where shallow-green and deep-green approaches disagree.
Overall assessment of international environmental agreements
Arguments that the agreements are successful
They have:
created continuing international environmental governance
brought large numbers of states into negotiations
established shared environmental targets
raised the prominence of climate change
created mechanisms for co-operation
demonstrated that states recognise environmental problems as global problems.
Paris in particular demonstrates the scale of international participation that environmental governance can achieve.
Arguments that the agreements are weak
However:
many commitments remain difficult to enforce
sovereign governments continue to control domestic implementation
states may avoid or weaken firm targets
market mechanisms may be criticised as loopholes
agreements can use long timescales
changing political leadership can weaken state commitments
financial promises can generate disputes
environmental protection continues to compete with economic growth.
A useful overall judgement
International environmental agreements have been more successful in constructing a global framework for environmental co-operation than in forcing states to take sufficient action.
Rio, Kyoto, Copenhagen and Paris demonstrate increasing willingness to treat environmental degradation as a global problem.
Yet the tragedy of the commons remains important because sovereign states still have incentives to protect their own short-term economic interests.
This explains why international environmental governance often follows a shallow-green model of negotiated, gradual reform, while deep-green critics argue that the environmental problem requires much more radical change.
The next stage is therefore to consider why sovereignty, inequality and disagreements about responsibility continue to obstruct international environmental action [Obstacles and non-state actors].
Key Words 🔑
Key word | Student-friendly definition | How it may be used in an exam |
Shallow-green ecology | An approach that seeks environmental protection through reform while allowing continued economic development. | Contrast its enlightened anthropocentrism and acceptance of growth with deep ecology. |
Deep-green ecology | An ecocentric approach demanding much more radical changes to growth, consumption and humanity's relationship with nature. | Use when analysing arguments that existing economic structures are themselves part of the environmental problem. |
Sustainable development | Development meeting present needs without compromising the ability of future generations to meet theirs. | Use when examining attempts to reconcile economic development with environmental protection. |
Tragedy of the commons | A situation where actors pursuing their own rational self-interest deplete a shared resource and damage the common good. | Use to explain why states may struggle to co-operate over global environmental problems. |
Global commons | Areas and resources that are un-owned and beyond national jurisdiction. | Use when explaining why environmental problems require international rather than purely national solutions. |
Hints from the Examiner Reports đź’ˇ
Examiner hint:Â Make shallow-green versus deep-green answers genuinely comparative. Edexcel's 2024 assessment required students to examine the differences between the two approaches. Strong analysis comes from comparing their attitudes to growth, capitalism, consumption and the value of nature rather than producing two unrelated descriptions. The mark scheme rewards coherent comparative chains of reasoning.
Examiner hint:Â Know the major environmental conferences accurately. The 2021 examiner report found that better candidates had a clear awareness of Kyoto, Copenhagen and Paris and used the growth of environmental summits to develop an argument about the increasing importance of environmental governance.
Examiner hint:Â Do not simply name Rio, Kyoto, Copenhagen and Paris. In 2022, stronger responses used knowledge of summits, state actions and environmental perspectives as part of developed arguments rather than treating them as isolated facts.
Examiner hint:Â Distinguish agreement from implementation. The 2023 examiner report noted the contrast between very broad commitment to environmental protection and the perceived inadequacy of actual state action. That distinction can turn AO1 knowledge into AO2 and AO3.
Examiner hint:Â Do not save evaluation for your conclusion. Pearson's 2022 report specifically advises that AO3 should appear throughout a 30-mark response alongside AO1 and AO2. Make a mini-judgement after each developed argument.
Common Mistakes ⚠️
Mistake: Saying shallow-green ecology does not care about the environment
Why this is incorrect: Shallow ecology accepts environmental responsibilities. Its disagreement with deep ecology concerns how radical the response needs to be, not whether environmental protection matters.
How to improve: Explain that shallow ecology supports reform, green capitalism and slower or more sustainable growth.
Mistake: Treating deep-green ecology as simply a more enthusiastic version of shallow ecology
Why this is incorrect: The disagreement is much deeper.
Deep ecology is ecocentric and questions growth, industrialism, consumerism and existing economic arrangements.
How to improve: Compare underlying values as well as policies.
Mistake: Confusing anthropocentrism with ecocentrism
Why this is incorrect: Anthropocentrism is human-centred, while ecocentrism prioritises ecological balance.
How to improve: Remember:
anthropocentric = humans at the centre
ecocentric = ecology at the centre
Mistake: Defining sustainable development as stopping development
Why this is incorrect: Edexcel defines sustainable development as meeting present needs without preventing future generations from meeting theirs.
It does not automatically require all development to stop.
How to improve: Focus on balancing present needs and future capacity.
Mistake: Saying the tragedy of the commons means everybody behaves irrationally
Why this is incorrect: The concept is powerful precisely because individual actors may behave rationally according to their own self-interest.
The tragedy emerges when those individually rational decisions combine to damage the shared resource.
How to improve: Use the chain:
rational individual behaviour → collective depletion → common loss
Mistake: Assuming Rio, Kyoto, Copenhagen and Paris are equally strong agreements
Why this is incorrect: They represent different stages and forms of environmental governance.
For example, Rio established the UNFCCC framework, while Pearson's materials identify Kyoto with binding targets and emissions mechanisms.
How to improve: Know a distinctive strength and weakness for each.
Mistake: Assuming international agreement means environmental success
Why this is incorrect: Governments may agree to targets while implementation remains difficult.
International environmental governance is largely intergovernmental.
How to improve: Separate:
agreement → commitment → implementation → environmental outcome
Mistake: Listing conference dates without analysis
Why this is incorrect: Knowing Rio 1992, Kyoto 1997, Copenhagen 2009 and Paris 2015 is useful AO1, but dates alone do not answer an analytical or evaluative question.
How to improve: Attach a political consequence to every example:
Paris had very broad participation → this strengthens legitimacy and demonstrates widespread recognition of climate change → but participation does not guarantee enforcement.
Exam-Style Questions ✍️
Question 1
Define sustainable development. (1)
Answer:
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. (1 mark)
Question 2
Define the tragedy of the commons. (1)
Answer:
A situation in which users of a shared resource act rationally in their individual self-interest but collectively deplete that resource and damage the common good. (1 mark)
Question 3
Explain two differences between shallow-green and deep-green ecology. (4)
Indicative answer:
Shallow ecology supports enlightened anthropocentrism, whereas deep ecology is ecocentric and gives greater priority to ecological balance. (2 marks)
Shallow ecology accepts continuing economic growth and green capitalism, whereas deep ecology demands much more radical changes to growth, production and consumption. (2 marks)
Question 4
Consider the following hypothetical situation:
Several states share access to an environmental resource. Each government knows that continued heavy use will eventually damage the resource. However, each fears that reducing its own use while other states continue will harm its economy without preventing the environmental damage.
Explain how this scenario illustrates the tragedy of the commons. (6)
Indicative answer:
Each state has an individually rational incentive to continue exploiting the resource because unilateral restraint could create an economic disadvantage. However, if all states behave according to the same self-interest, the shared resource is depleted. The case therefore illustrates how individually rational decisions can combine to damage the common good and why international environmental co-operation is necessary.
Question 5
Explain two strengths and one weakness of international environmental agreements. (6)
Indicative mark scheme:
Credit developed explanations such as:
agreements establish environmental issues as shared international concerns
they provide targets around which states can co-operate
repeated conferences create continuing global environmental governance
broad participation increases legitimacy
weakness: agreements often depend upon state implementation and may lack strong enforcement
weakness: flexible mechanisms and vague commitments may allow governments to avoid significant action.
Maximum marks require development rather than a simple list.
Question 6
Examine the differences between shallow-green ecology and deep-green ecology over how environmental issues should be tackled. (12)
Indicative mark scheme:
AO1: Knowledge and understanding
Students may explain that:
shallow ecology accepts economic growth, although potentially at a slower rate
deep ecology demands more radical changes to growth
shallow ecology is based on enlightened anthropocentrism
deep ecology is ecocentric
shallow ecology supports green capitalism
deep ecology challenges consumerism, materialism and industrial production
deep ecology favours more localised production and reduced use of non-renewable resources.
AO2: Analysis
Students may analyse that:
the approaches offer fundamentally different relationships between humans and nature
shallow ecology attempts to reconcile existing economic systems with environmental protection
deep ecology considers those economic systems part of the environmental problem
shallow policies may be politically easier to implement
deep policies may potentially create more rapid environmental change but face stronger public resistance.
For the highest level, comparisons should be explicit and sustained.
Question 7
Examine the strengths and weaknesses of international environmental agreements since the Rio Earth Summit. (12)
Indicative mark scheme:
AO1: Knowledge and understanding
Students may refer to:
Rio 1992 and the creation of the UNFCCC framework
Kyoto 1997 and emissions commitments, binding targets, carbon trading and carbon sinks
Copenhagen 2009 and continuing international targets and negotiations
Paris 2015 and very broad international participation
weaknesses including vague or voluntary commitments, long timeframes and weak enforcement.
AO2: Analysis
Students may explain that:
Rio established an enduring international framework
Kyoto demonstrated movement towards more concrete commitments
repeated conferences show increasing international recognition of environmental problems
Paris demonstrates the capacity of global governance to achieve broad agreement
however, state sovereignty limits implementation
flexible mechanisms may increase participation while reducing the strength of commitments
agreement is therefore a weaker measure of success than actual environmental implementation.
Question 8
Evaluate the view that deep-green ecology provides a more effective response to environmental problems than shallow-green ecology. (30)
Indicative mark scheme:
Arguments supporting the view may include:
deep ecology addresses underlying causes such as consumerism and materialism
it challenges continual economic growth
ecocentrism gives greater priority to environmental balance
localised production and reduced reliance on non-renewable resources could produce more rapid environmental change
Pearson's 2024 material recognises the argument that deep-green measures may make international environmental targets easier to meet.
Arguments challenging the view may include:
radical reductions in consumption may face major political resistance
deep-green policies could significantly affect living standards and economic growth
shallow-green reform may be more politically achievable
green capitalism and technological change may allow environmental objectives to be pursued through existing systems
a policy that is environmentally radical but politically impossible may have less practical impact than moderate measures governments will implement.
AO3 evaluation:
A strong response should establish a criterion for effectiveness.
If effectiveness means the scale of environmental change, deep ecology has the stronger claim.
If effectiveness means the likelihood that governments and populations will accept and implement policies, shallow ecology may be more successful.
The strongest conclusion will balance environmental ambition against political feasibility.
Question 9
Evaluate the view that international environmental agreements have been successful in overcoming the tragedy of the commons. (30)
Indicative mark scheme:
Arguments supporting the view may include:
Rio created a framework for continued global environmental co-operation
Kyoto introduced clearer emissions commitments
Copenhagen continued international negotiations and global targets
Paris achieved extremely broad international participation
repeated agreements demonstrate that states can recognise shared interests
international institutions create mechanisms through which states can co-operate rather than act independently.
Arguments challenging the view may include:
states remain sovereign and can continue prioritising national interests
environmental commitments may be vague or voluntary
enforcement is weak
governments may fear economic disadvantages from stronger environmental action
carbon trading and other flexible mechanisms may reduce the need for direct cuts
changing national leadership can affect participation
the continued need for repeated agreements itself suggests that collective-action problems remain.
Overall judgement:
International agreements have reduced the tragedy of the commons by creating forums, shared expectations and collective commitments.
However, they have not eliminated the underlying incentive for states to place short-term national economic interests ahead of the global environmental good.
Question 10
Evaluate the view that the Paris agreement represents a more effective form of global environmental governance than earlier international environmental agreements. (30)
Indicative mark scheme:
Arguments supporting the view may include:
Paris achieved extremely broad international participation
wide participation is particularly important for a genuinely global environmental problem
it demonstrates widespread recognition that climate change requires international action
it continued and developed the international process begun at Rio and extended through Kyoto and Copenhagen
broad agreement strengthens political legitimacy.
Arguments challenging the view may include:
wider participation may depend upon greater flexibility
weak enforcement continues to limit international agreements
sovereign states still determine domestic implementation
national political changes can undermine commitment
Kyoto included binding targets and therefore may be regarded as stronger in some respects
broad agreement is not the same as effective environmental outcomes.
Overall judgement:
Paris can be regarded as particularly successful at securing participation and international consensus.
Whether it is more effective overall depends upon whether effectiveness is judged by the number of states involved or by the ability of agreements to produce and enforce substantial environmental change.
