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 ...

This paper examines the how the South Asian countries are addressing their energy deficiency as the capacity to refine imported crude oil is limited except India. India has developed substantial refining capacity (247.6 million tons per annum) compared to Pakistan (18.8 mtpa) and Bangladesh (1.5 mtpa). India’s refining capacity is being currently utilized nearly 100%. Having no local refining capa...

The Oil Information data service contains time series of oil data for 38 OECD countries and 14 European non-OECD countries from 1960 to 2023 with provisional estimates for 2024. Country aggregates for OECD Total, OECD Americas, OECD Asia Oceania, OECD Europe, IEA Total, EU27 (excluding the United Kingdom) and EU28 are also included.Statistics are available for detailed supply/demand balances, end-...

This document provides a roadmap for the development and implementation of fuel economy policies for ASEAN Member States (AMS), aimed primarily at regulators in government agencies who are or who should be involved in fuel economy policy development. The roadmap is intended to serve as catalyser to engage all relevant stakeholders from government, industry and academia. It not only addresses exper...
