Energy is the main contributor to air pollution that kills millions each year, but a 7% increase in energy investment could cut death toll significantly, says new IEA report.London, 27 June – Each year an estimated 6.5 million deaths are linked to air pollution with the number set to increase significantly in coming decades unless the energy sector takes greater action to curb emissions. Air pollution is a problem felt around the world, particularly the poorest in society.
No country is immune as a staggering 80% of cities that monitor pollution levels fail to meet the air quality standards set by the World Health Organization. Premature deaths from outdoor air pollution are projected to rise from 3 million today to 4.5 million by 2040, concentrated mainly in developing Asia.
Meanwhile, premature deaths from household air pollution will decline from 3.5 million to 3 million over the same period, although they continue to be heavily linked to poverty and an inability to access modern energy.
In its first ever in-depth analysis of air quality, the IEA’s World Energy Outlook (WEO) special report released today highlights the links between energy, air pollution and health. It identifies contributions the energy sector can make to curb poor air quality, the fourth-largest threat to human health, after high blood pressure, poor diets, and smoking.
Energy production and use – mostly from unregulated, poorly regulated or inefficient fuel combustion – are the most important man-made sources of key air pollutant emissions: 85% of particulate matter and almost all of the sulfur oxides and nitrogen oxides. Millions of tonnes of these pollutants are released into the atmosphere each year, from factories, power plants, cars, trucks, as well as the 2.7 billion people still relying on polluting stoves and fuels for cooking (mainly wood, charcoal and other biomass).
In the central outlook of the WEO special report, growing attention to this issue and an accelerating energy transition post-COP21 puts global emissions of these pollutants on a slowly declining trend to 2040. However, the problem is far from solved and global changes mask strong regional differences: emissions continue to fall in industrialised countries. In China, recent signs of decline are consolidated. But emissions generally rise in India, Southeast Asia and Africa, as expected growth in energy demand dwarfs policy efforts related to air quality.
“Clean air is a basic human right that most of the world’s population lacks,” said IEA Executive Director Fatih Birol. “No country – rich or poor – can claim that the task of tackling air pollution is complete. But governments are far from powerless to act and need to act now. Proven energy policies and technologies can deliver major cuts in air pollution around the world and bring health benefits, provide broader access to energy and improve sustainability.”
The air quality outlook is not set in stone, but rather it is a policy choice. The report presents strategies tailored to various country circumstances to deliver cleaner air for all. A Clean Air Scenario demonstrates how energy policy choices backed by just a 7% increase in total energy investment through 2040 produce a sharp improvement in health. Under such a scenario, premature deaths from outdoor air pollution would decline by 1.7 million in 2040 compared with our main scenario, and those from household pollution would fall by 1.6 million annually.
The IEA strategy for cleaner air requires the implementation of a number of proven policies. Actions to deliver access to clean cooking facilities to an additional 1.8 billion people by 2040 are essential to reducing household emissions in developing countries, while emissions controls and fuel switching are crucial in the power sector, as is increasing energy efficiency in industry and emissions standards that are strictly enforced for road transport. Overall, the extra impetus to the energy transition means that global energy demand is 13% lower in 2040 than otherwise expected and, of the energy that is combusted, three-quarters is subject to advanced pollution controls, compared with only around 45% today.
“We need to revise our approach to energy development so that communities are not forced to sacrifice clean air in return for economic growth,” said Dr Birol. “Implementing the IEA strategy in the Clean Air Scenario can push energy-related pollution levels into a steep decline in all countries. It can also deliver universal access to modern energy, a rapid peak and decline in global greenhouse-gas emissions and lower fossil-fuel import bills in many countries.”
Aligned with its energy policy strategy for cleaner air, the WEO special report highlights three key areas for government action:
- Setting an ambitious long-term air quality goal, to which all stakeholders can subscribe and against which the efficacy of the various pollution mitigation options can be assessed.
- Putting in place a package of clean air policies for the energy sector to achieve the long-term goal, drawing on a cost-effective mix of direct emissions controls, regulation and other measures, giving due weight to the co-benefits for other energy policy objectives.
- Ensuring effective monitoring, enforcement, evaluation and communication: keeping a strategy on course requires reliable data, a continuous focus on compliance and on policy improvement, and timely and transparent public information.

About the IEA Founded in 1974, the International Energy Agency was initially designed to help countries co-ordinate a collective response to major disruptions in the supply of oil. While this remains a key aspect of its work, the IEA has evolved and expanded. It is at the heart of global dialogue on energy, providing authoritative statistics and analysis. The IEA examines the full spectrum of energy issues and advocates policies that will enhance the reliability, affordability and sustainability of energy in its 29 member countries and beyond.
