The Arctic is a vital region that helps preserve the balance of the global climate. The Arctic environment is particularly sensitive to short-lived climate pollutants, including black carbon, due to their strong warming effect.

This report quantifies the environmental, health and economic consequences of policy action on air pollution in Arctic Council countries, with a focus on sectoral differences. The report takes a modelling approach and compares a baseline scenario that reflects current legislation, with a policy scenario in which the best available techniques to reduce emissions are deployed in all emitting sectors. The report highlights that benefits from air quality improvements can be obtained when considering emission reductions throughout the economy, and not just in the sectors that are targeted more often, such as industry and transport. The results presented in the report also highlight the need for country-specific policy strategies that take into account the current levels of policy stringency, the sectoral contributions to air pollution, and the need for sectoral investment in new technologies, which also vary by country.

The Arctic is a vital region that helps preserve the balance of the global climate. The Arctic environment is particularly sensitive to short-lived climate pollutants, such as black carbon, which is the most light-absorbing component of particulate matter. Ambitious policy action to reduce air pollution would therefore reduce the negative environmental, health and economic impacts of air pollution, while slowing down climate change by reducing emissions of short-lived climate pollutants.Due to their proximity to the Arctic region, a central role in reducing air pollution in the Arctic is played by Arctic Council countries, namely Canada, Denmark, Finland, Iceland, Norway, the Russian Federation, Sweden, and the United States. Arctic Council countries have affirmed their support to collectively bring black carbon emissions down by 25-33% by 2025 from 2013 levels. Ambitious policy action to reduce air pollution in Arctic Council countries would help achieve this target.This paper presents a quantitative assessment of the environmental, health and economic consequences of ambitious policy action to reduce air pollution in Arctic Council countries. The scenario analysis is based on a suite of modelling tools to project the impacts of increasingly ambitious policies up to 2050. The paper compares a business-as-usual scenario with policy scenarios in which Arctic Council countries, and other regional groupings, adopt the best available techniques to reduce air pollutant emissions, including end-of-pipe technologies, the use of cleaner fuels, and measures to reduce emissions in the agricultural sector.The modelling shows that these policies could substantially curb emissions of several air pollutants, including bringing black carbon emissions well below the collective target. The benefits would include better air quality, and reductions in air pollution-related premature deaths and illnesses. The costs of achieving the emission reductions would be offset by the economic benefits resulting from improved human and environmental health.

This report provides a comprehensive assessment of the economic consequences of outdoor air pollution in the coming decades, focusing on the impacts on mortality, morbidity, and changes in crop yields as caused by high concentrations of pollutants.

Outdoor air pollution kills more than 3 million people across the world every year, and causes health problems from asthma to heart disease for many more. This is costing societies very large amounts in terms of the value of lives lost and ill health. Based on extensive new epidemiological evidence since the 2010 Global Burden of Disease study, and OECD estimates of the Value of Statistical Life, this report provides evidence on the health impacts from air pollution and the related economic costs.
