Environment as a Global Political Challenge
IB DP Global Politics — HL extension: Global political challenges | HL | Environment
📋 What You Will Learn
- Define key environmental concepts including climate change, ecological sustainability, the commons, and environmental justice
- Explain why environmental challenges are inherently political — involving power, competing interests, and contested values
- Analyse the roles of states, IGOs, civil society, corporations, and affected communities in shaping environmental governance
- Compare how different theoretical perspectives (realism, liberalism, postcolonialism, ecofeminism) interpret environmental politics
- Evaluate the effectiveness of international environmental agreements and governance mechanisms
- Examine the relationship between environment, development, sovereignty, and justice across multiple levels of analysis
🔍 Guiding Question When the costs of environmental destruction fall disproportionately on those least responsible for it, and when effective solutions require states to surrender some control over their own resources and economies, is meaningful global environmental governance possible — or does power always determine who pays the price?
🌍 Why This Matters In 2023, the small island state of Tuvalu signed a treaty with Australia granting its citizens the right to migrate as sea levels threaten to submerge the entire nation — the first agreement of its kind in history. Tuvalu contributes less than 0.001% of global greenhouse gas emissions, yet faces complete territorial extinction. This is not merely an environmental story; it is a story about power, sovereignty, justice, and who bears the costs of decisions made by others.
🔑 Key Concept Link Environment engages all four key concepts simultaneously. Sovereignty is challenged when states must cede control over their own resources and emissions to meet collective targets. Power shapes who sets the environmental agenda, who enforces it, and who is exempted. Legitimacy is at stake when affected communities — especially in the Global South — are excluded from decisions that determine their survival. Interdependence is the defining feature of environmental politics: no state can solve climate change, biodiversity loss, or ocean pollution alone, yet cooperation requires overcoming deep conflicts of interest. Return to these four concepts throughout.
Why Environment Is a Political Issue
It is tempting to treat environmental problems as purely scientific or technical — a matter of measuring carbon parts per million or calculating species loss. But every environmental question is also a political question: who has the right to use natural resources, who bears the costs of environmental damage, who has the authority to regulate behaviour, and whose knowledge counts. Politics is inescapable.
📖 Definition — Environmental Politics Environmental politics refers to the processes by which societies make collective decisions about the use, protection, and distribution of natural resources and environmental goods, including the negotiation of who bears the costs and benefits of environmental change.
- Scarcity and competition: natural resources — water, land, fisheries, fossil fuels — are finite; their allocation involves winners and losers, generating political conflict at every level.
- Externalities and the commons: environmental damage often crosses borders and affects people who had no say in the decisions that caused it — the classic "tragedy of the commons" problem at global scale.
- Contested values: economic development, ecological preservation, intergenerational equity, and indigenous land rights are all legitimate values that frequently conflict.
- Unequal vulnerability: the same environmental event (a flood, a drought, a heatwave) affects wealthy
