Greenhouse gas (GHG) emissions and air pollution have many common sources. They also share solutions. By integrating air quality management and climate action planning processes, cities can meet local air quality goals and climate goals, while improving residents’ quality of life. This detailed guide to integrated planning, and its summary for policy makers, provides a framework to support cities ...

The research project highlighted common sources and impacts of workplace air pollution in Southeast Asia, such as street food vendors' exposure to grilling emissions. Regional cooperation is essential for sharing solutions, including technological measures, knowledge on addressing occupational air pollution, and assessments of policy effectiveness. The project emphasizes the need for increased and...

Millions of used cars, vans and minibuses exported from Europe, the USA and Japan to low- and middle-income countries are hindering efforts to combat climate change. They are contributing to air pollution and are often involved in road accidents. Many of them are of poor quality and would fail road-worthiness tests in the exporting countries. A landmark, first-of-its-kind United Nations Environmen...

The report "Options for Ammonia Abatement: Guidance from the UNECE Task Force on Reactive Nitrogen" provides comprehensive strategies for controlling and reducing ammonia emissions, which are a significant environmental pollutant. It outlines various abatement techniques, including technological and management practices, aimed at mitigating ammonia emissions from agricultural sources. This guidanc...

The Plain English Guide to the Clean Air Act provides an overview of the Clean Air Act, explaining its purpose, history, and key components. It highlights the importance of addressing air pollution for health, environmental, and economic reasons, and outlines the roles of the EPA, state, tribal, and local governments in implementing and enforcing air quality standards. The guide also details vario...

In order to follow and facilitate the HFC phase-down schedules contained in the Kigali Amendment, the Parties, including both developed and developing countries, will have to implement certain measures. This booklet contains a recommended set of legislative and policy options which the developing (Article 5) countries may wish to consider for implementation. It is intended to be a guide/tool for c...

In order to guide policy-makers in the development of strategic plans to protect their populations from the adverse health impacts of rapid urbanization, the WHO Urban Health Initiative has undertaken a series of projects to train government representatives in the use of tools to objectively evaluate health impact of policies and development trajectories. The integrated set of models provides a fr...

Decarbonization is a process that transforms economies to lower greenhouse gas (GHG) emissions per unit of economic output, aiming towards net-zero GHG emissions. This process could also reduce short-lived climate pollutant (SLCP) emissions, including black carbon and methane. They have relatively short atmospheric lifetimes but have large radiative forcing and impact human health. Therefore, redu...

Limiting global temperature increases to 1.5 °C while respecting ‘the right to health’ requires substantial reductions in Short-Lived Climate Pollutants (SLCPs), including methane, black carbon and hydrofluorocarbons, and co-emitted air pollutants. This study evaluates the inclusion of SLCP and air pollutant mitigation within Nationally Determined Contributions (NDCs) that were submitted between 2...

The objective of this report is to highlight the opportunities in the ASEAN region for more equitable and inclusive policymaking on air pollution – in terms of developing evidence-based policies through use of gender disaggregated data collection and analysis and in terms of the impacts of their implementation. We highlight here the unequal burdens of air pollution by sharing ASEAN region case stu...
