A child in Lahore breathing polluted air, a farmer in Sindh watching floodwaters destroy his crops and a family in Balochistan struggling with drought and extreme heat are experiencing different consequences of an environmental crisis that extends far beyond national borders. Climate change has exposed one of the deepest inequalities in the modern world. Its causes, consequences and financial costs are distributed unevenly, leaving countries with limited resources to confront a crisis they contributed relatively little to creating. Pakistan stands on the frontline of a crisis it has done relatively little to create. Its exposure to climate disasters is immense, yet its share of global greenhouse gas emissions remains marginal. The disparity lies in the growing gap between those who contribute most to environmental damage and those who have the least capacity to survive its consequences.
Pakistan’s Nationally Determined Contribution 3.0, submitted in 2025, places the country among the world’s relatively low per-capita greenhouse gas emitters, at approximately 2.3 tonnes of carbon dioxide equivalent per person. Yet it faces disproportionate exposure to climate hazards, including accelerated glacial melting, recurrent floods, prolonged droughts, rising temperatures and changing rainfall patterns. The country’s experience during the 2022 floods demonstrated the scale of this vulnerability. More than 33 million people were affected, over 1,700 lost their lives, and the combined damages and economic losses exceeded $30 billion. The disaster destroyed homes, damaged agricultural land, disrupted transport networks and pushed already vulnerable households towards deeper poverty. These were not merely losses recorded in government assessments. They represented years of household savings, livelihoods and economic security washed away within weeks.
The crisis is no longer confined to floods and extreme weather. Pakistan’s recurring urban smog reveals another dimension of environmental insecurity. Lahore, Faisalabad, Gujranwala and other urban centres continue to experience dangerous concentrations of particulate pollution. The latest figures offer a revealing picture of the problem. According to an analysis by the Pakistan Air Quality Initiative, Lahore’s average PM2.5 concentration declined by 27% in October 2026 compared with the same month last year across 26 monitoring sites. However, after accounting for weather conditions, the actual improvement was estimated at 4%. More disturbing is that pollution exceeded Pakistan’s prescribed daily limit on every day of October. The situation deteriorated further in early November, when Lahore’s Air Quality Index crossed 530, with Gujranwala experiencing even more severe pollution. Emissions from vehicles, industries, brick kilns and agricultural residue burning, combined with unfavourable atmospheric conditions, continue to undermine urban air quality. Smog is not simply a consequence of global warming. It also reflects domestic pollution, weak enforcement, inadequate transport planning and the failure to regulate industrial emissions. Climate change and air pollution are distinct problems, but together they expose the growing inability of public institutions to protect people from environmental hazards. A child should not have to sacrifice the right to breathe clean air because governments cannot enforce environmental standards
The international dimension of this injustice is equally important. Wealthier industrialised economies have accumulated much of the historical emissions responsible for global warming, while developing countries face mounting adaptation costs and disaster-related losses. International climate agreements recognise the principle of common but differentiated responsibilities, acknowledging that countries have different historical contributions and capacities. Yet climate finance remains a contentious issue. At COP29 in 2024, developed countries agreed to take the lead in mobilising at least $300 billion annually for developing countries by 2035, alongside a broader ambition to scale up financing from all sources to $1.3 trillion annually. For vulnerable economies, the difference between announced commitments, actual disbursements, grants and loans is substantial. A country already struggling with debt cannot be expected to finance its climate survival through additional borrowing.
Pakistan’s own climate commitments reveal the magnitude of the challenge. Its 2025 NDC 3.0 estimates that achieving its climate objectives will require approximately $565.7 billion by 2035. The proposed emissions reduction target of 50% by 2035 is divided between a 17% unconditional commitment and a further 33% dependent on international financial support, technology transfer and capacity building. These figures expose the gap between climate ambition and financial capacity. Pakistan cannot reasonably be expected to undertake an expensive transition towards cleaner energy, resilient infrastructure, sustainable transport and climate-smart agriculture without access to affordable financing. At the same time, international assistance cannot become an excuse for domestic inaction. Environmental regulation, urban transport reform, industrial compliance, water conservation, forest protection and accountable disaster management require sustained national commitment.
The consequences extend beyond Pakistan. Bangladesh faces recurring coastal flooding and displacement, small island states confront rising sea levels, and parts of Africa face prolonged drought and growing food insecurity. These countries differ in geography and economic circumstances, but share an uncomfortable reality. Their populations are increasingly exposed to environmental threats while their financial capacity to respond remains limited. Climate migration, food insecurity and competition over water will increasingly affect economic stability, regional relations and international security. Treating these consequences as isolated national emergencies overlooks their common global origins and the need for collective responsibility.
Climate action must move beyond diplomatic declarations and conference commitments. It requires predictable financing, greater access to grants and concessional resources, technology transfer, effective loss-and-damage arrangements and greater accountability for those responsible for emissions. It also requires vulnerable countries to strengthen their own institutions and ensure that available resources reach the communities most at risk. Pakistan cannot continue responding to every flood through emergency relief or to every smog episode through temporary restrictions. Its climate challenge demands a fundamental shift towards prevention, adaptation and effective environmental governance. The gap between responsibility for climate change and exposure to its consequences is becoming one of the defining inequalities of our time. The atmosphere belongs to everyone, but its destruction is exacting the heaviest price from those least able to bear it.
