The Unpaid Climate Debt: Historical Responsibility
For decades, developed nations fueled their industrialization and economic growth with fossil fuels, emitting vast quantities of greenhouse gases into the atmosphere. This historical emissions legacy has created a 'climate debt' to the Global South, which now bears the brunt of a crisis it largely did not cause. The principle of 'common but differentiated responsibilities and respective capabilities' (CBDR-RC), enshrined in the UNFCCC, acknowledges this uneven contribution. According to the World Resources Institute (WRI), [2021], the United States is responsible for the largest share of historical greenhouse gas emissions, contributing approximately 25% of cumulative global emissions from 1850-2019, with the EU-27 responsible for around 17%. In stark contrast, the average per capita CO2 emissions in high-income countries were around 9.2 tons in 2021, compared to approximately 2.5 tons in low-income countries, according to the Global Carbon Project, [2022].
Pakistan, ranked 8th among countries most affected by extreme weather events by the Germanwatch Global Climate Risk Index, [2021, for 2019 data], exemplifies this injustice. Our farmers, coastal communities, and urban centres face existential threats while contributing negligibly to the problem. The financial support required for adaptation, mitigation, and 'loss and damage' is not a handout; it is restitution for a harm already inflicted, a debt owed.
Climate Change as a Human Rights Crisis
The impacts of climate change are not merely environmental; they are profound human rights violations. The right to life, health, food, water, housing, and self-determination are all imperiled by rising temperatures, extreme weather events, and environmental degradation. When floods destroy homes and livelihoods, when droughts decimate crops, or when heatwaves render entire regions uninhabitable, fundamental human rights are systematically eroded. According to the Internal Displacement Monitoring Centre (IDMC), [2023], over 32 million new internal displacements were triggered by disasters in 2022, with weather-related events being the primary driver. The Lancet Countdown on Health and Climate Change, [2023], reported that heat-related deaths among people over 65 increased by approximately 85% between 1990-1999 and 2013-2022.
International human rights law imposes duties on states to protect their populations from foreseeable harm, including harm stemming from environmental degradation. Furthermore, states have extraterritorial obligations to ensure their actions do not infringe upon human rights in other countries. The failure of major emitters to adequately reduce emissions and support vulnerable nations constitutes a dereliction of these duties.
"Climate change is the biggest global health threat facing the world in the 21st century, but it is also the greatest opportunity to redefine the social and environmental determinants of health." – Dr. Margaret Chan, former Director-General, World Health Organization (WHO), [2015].
The Legal Principle of 'No Harm' and State Responsibility
At the core of international environmental law lies the principle of 'no harm' (or sic utere tuo ut alienum non laedas – use your own property in such a manner as not to injure that of another). This principle dictates that states have a responsibility to ensure that activities within their jurisdiction or control do not cause damage to the environment of other states or of areas beyond the limits of national jurisdiction. The transboundary nature of greenhouse gas emissions unequivocally links the industrial activities of one nation to the environmental and human costs in another.
This legal duty extends beyond mere mitigation. It encompasses the responsibility to compensate for harm already caused and to provide the means for adaptation to inevitable changes. The international community, through various conventions and declarations, has implicitly and explicitly recognized this. The IMF, [2023], warns that unmitigated climate change could reduce global GDP by approximately 7% by 2100, underscoring the vast economic damage being inflicted. The annual adaptation costs for developing countries are estimated to be USD 215-387 billion per year by 2030, according to the UNEP Adaptation Gap Report, [2023]. These are not optional expenses; they are consequences of a global failure to adhere to the 'no harm' principle.
Addressing the Counterargument
Some argue that while historical emissions are a factor, developing nations are also rapidly increasing their emissions and must take responsibility. This perspective, while holding some truth for future mitigation efforts, deliberately obscures the fundamental injustice of the past and present. Developing nations, including Pakistan, are striving for economic development to lift their populations out of poverty, often with far lower per capita emissions than their developed counterparts. The argument that all nations should bear equal responsibility for a problem predominantly created by a few ignores the historical context and the current capacity gap. The focus should be on additional and new finance for climate action in developing countries, not diverting existing aid or placing the burden of historical emissions solely on those least responsible.
A Path Towards Enforceable Justice
For Pakistan and other climate-vulnerable nations, the pursuit of climate justice must transcend diplomatic pleas and enter the realm of legal enforceability. This requires strengthening international legal frameworks, exploring avenues for climate litigation in international courts, and establishing binding mechanisms for 'loss and damage' finance. The recent establishment of the Loss and Damage Fund at COP28 is a nascent step, but its operationalization and adequate capitalization remain critical challenges. It must be recognized as a legal entitlement, not a discretionary fund.
Pakistan, as a prominent voice for the Global South, must continue to champion this cause, advocating for a paradigm shift where international law unequivocally recognizes climate justice as a non-negotiable obligation. Only then can we move beyond the charade of charity and demand the justice that is our right, ensuring a more equitable and sustainable future for all.
