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.

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...

The report is an outcome of the last component of the UHI model process, policy tracking and monitoring outcomes. The report proposes a framework for tracking urban health policies, with a special focus on the impacts of air quality and energy access on human health and well-being in African countries, giving some examples from the pilot project in Accra. The report also provides resources to surv...

The report, "Seeking Synergy Solutions: Integrating Climate and SDG Knowledge and Data for Action," highlights the necessity of bridging the gap between climate action and sustainable development goals (SDGs). It emphasizes the importance of integrated policies to enhance resource efficiency and policy coherence, stressing the need for accessible and relevant data to support synergistic decision-m...

The report emphasizes the importance of addressing short-lived climate pollutants (SLCPs) to simultaneously combat climate change and improve air quality. It highlights integrated policy approaches that target both greenhouse gases and SLCPs, like methane and black carbon, for synergistic benefits. The document also provides guidance on leveraging air quality management frameworks to implement eff...

The "Toolkit for MSMEs to Control Air Pollution" provides a comprehensive guide for Micro, Small, and Medium Enterprises (MSMEs) to identify and mitigate air pollution sources within their operations.
