Air Quality Index (AQI)- AIRNow

The AQI tells the user the quality of the air in any region, state or local major metropolitan area and whether it will affect your health. EPA, state, and local agencies work together to report current and forecast conditions for ozone and particle pollution. AIRNow describes current conditions and also forecasts next-day air quality. It also allows the viewer to visualize the changing conditions hourly from the previous 24-hour period. Read More

Mobile Source Emissions: Past, Present and Future

This site presents information on air pollution from vehicles, engines, and other machines that move. Includes information on motorized vehicles, equipment, tools, etc. which typically are not considered part of the mainstream pollution generating vehicles such as the automobile. Read More

Symposium Summary: 2003 MIT Symposium on Particulate Matter

The 2003 MIT Symposium on Particulate Matter was an event that comprehensively discussed issues around particulate matter pollution including emissions trends, health effects, monitoring, and policy. This document summarizes the remarks of various researchers and policy makers, including Noble laureate Mario Molina, on the current knowledge of effects and effective policy of particulates in the atmosphere.

Are Cap-and-Trade Programs more Environmentally Effective than Conventional Regulation?

This paper explores the consequences of cap-and-trade policies, where the total air pollutant emissions of a whole set of polluters are limited, and they are allowed to trade among themselves for the right to pollute up to the cap. The paper focuses on whether these policies have been effective in addressing environmental problems. The article provides background on the policies of U.S. cap-and-trade programs and provides a policy analysis of the effectiveness of these programs. Read More

Sources of Emission Reductions: Evidence from U.S. SO2 Emissions from 1985 through 2002

This paper describes database studies that have examined where the greatest emission reductions in sulfur dioxide have occurred over the past twenty years. Specifically, the paper examines whether reductions have come from retrofits of existing power generation plants, or replacement of old plants with new generating capacity. The paper finds that the greatest reductions have been gained through plant retrofits, though new plants have also displace potential emissions from the generation facilities they replaced.

On the Road in 2020, a Life-cycle Analysis of New Automobile Technologies

The study provides a comparative analysis of passenger vehicle technologies that could be on the market by the year 2020. The authors analyzed cost,energy consumption and greenhouse gas emissions over the entire life cycle of the vehicle. The authors also studied the impact of the transition to these technologies on significant stakeholders. Read More

Fuel Savings Potential and Costs Considerations for US Class 8 Heavy Duty Trucks through Resistance

This report explores options for greater fuel efficiency in heavy duty commercial trucks. Strategies explored include changes to driving resistance, fuel technology, engine technology, and driver skills. The authors find that significant fuel efficiencies could be gained through technological and skill improvements. The authors also compared urban and highway driving, and their effects on efficiency improvements. Read More

Final Report: EPA Center for Airborne Organics

The document summarizes the accomplishments of the EPA Center for Airborne Organics; including summaries of research projects, symposia, and the development of the center itself. The central concern of the research was the production of organic air pollutants and their effects. Topics include the chemistry of airborne organics, engine production of organics, fuel additives, particulates, soot, aromatic hydrocarbons, aerosols, transport and transformation of air pollutants, monitoring and source attribution, and regulation. This is the final report of a cross-institute collaboration of the Massachusetts Institute of Technology, California Institute of Technology, and the New Jersey Institute of Technology. Read More
