The Partnership for Clean Fuels and Vehicles (PCFV) has been working with developing and transitional countries to reduce vehicular air pollution through the promotion of cleaner fuels and vehicles. This regulatory toolkit is part of that ongoing campaign and is meant to introduce the need for a systems approach to vehicle emission reduction. A systems approach matches fuels and vehicle improvemen...

Including non-CO₂ pollutants and air quality measures in the upcoming round of Nationally Determined Contributions (NDC 3.0) offers a wide range of benefits to countries from improvements to the climate, human health, food security, energy security, economic development, and beyond.Optimizing these benefits requires understanding and capacity as well as effective coordination and engagement from e...

The Regional Climate Strategy, supported and led by ECOWAS, creates a coherent basis for long-term climate action (2030 and 2050 horizons). It aims to consolidate and make coherent an intervention framework for the fight against climate change in the ECOWAS zone, taking into account both the adaptation and mitigation dimensions of climate change in line with the Paris Agreement and the 2030 Agenda...

Several publications were released in recent years that have provided insights and better understanding of short-lived climate pollutant (SLCP) science, including on their emissions, inventories and impacts, as well as on the benefits of emissions mitigation. They have also provided stronger scientific basis for action on SLCPs.This Climate and Clean Air Coalition Scientific Advisory Panel 2018 An...

The AERMOD Modeling System is a steady-state plume model that incorporates air dispersion based on planetary boundary layer turbulence structure and scaling concepts, including treatment of both surface and elevated sources, and both simple and complex terrain.This document provides information on the recommended use of AERMOD to address specific issues and concerns related to the implementation o...

Global anthropogenic emission inventories remain vital for understanding the sources of atmospheric pollution and the associated impacts on the environment, human health, and society. Rapid changes in today's society require that these inventories provide contemporary estimates of multiple atmospheric pollutants with both source sector and fuel type information to understand and effectively mitiga...

The MODIS instrument is operating on both the Terra and Aqua spacecraft.  It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.405 and 14.385 µm, and it acquires data at three spatial resolutions -- 250m, 500m, and 1,000m.Along with all the data from other instruments on board the Terra spac...

In existence for more than 50 years, and with participants coming from all over the world, especially the main motor vehicle producing countries, the World Forum for Harmonization of Vehicle Regulations (WP 29) offers a unique framework for globally harmonized regulations on vehicles. The benefits of such harmonized regulations are tangible in road safety, environmental protection and trade.WP.29 ...

The Partnership for Clean Fuels and Vehicles (PCFV) is a global public-private partnership working with developing and transitional countries to reduce air pollution from vehicles through the promotion of cleaner fuels and vehicles.  EPA was a charter member of the Partnership, which began its work in 2002 and now includes 73 partners. The partnership kicked off its international cooperation ...

This study focuses on efforts in Southern and Western Africa by the Climate and Clean Air Coalition’s Heavy-Duty Diesel Vehicles and Engines Initiative to reduce vehicles’ contribution to outdoor air pollution, and the health and climate impacts of vehicles’ emissions. The goal of this report is to provide a roadmap to support the implementation of comprehensive clean fuel and vehicle policies in ...
