ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Despite this, research on the environmental and health impacts of tire wear has been neglected in comparison to the research and innovations dedicated to tackling fuel emissions.

Setting New Standards for Clean Cars

Plug in America

A normal vehicle releases several tons of pollutants each year, which depends on the vehicle’s fuel, fuel economy, and how far it is driven annually. federal government has worked on two programs in particular: EPA’s Light Duty Vehicle Emissions (LDV) Standards and NHTSA’s Corporate Average Fuel Economy (CAFE) Standards.

Error bars in b capture the standard error. However, aerosols have a much shorter lifespan in the atmosphere than the gases responsible for global warming, resulting in an atmospheric distribution that varies by region, especially in comparison to carbon dioxide.

Air pollutant emission 2010 limits exceeded in twelve EU Member States; road transport NOx a main factor

Green Car Congress

For the first time, preliminary data recently reported to the EEA by Member States allow a comparison with the legally binding emission limits for 2010 set in the EU NEC Directive. These pollutants can cause respiratory problems, contribute to the acidification of soil and surface water, and damage vegetation. Jacqueline McGlade.

IHS: continued legislative focus on pollutants to drive sensor market for internal combustion engines

Green Car Congress

In 1993, five to seven sensors were required to meet the Euro emissions standard 1 set for European countries. In comparison, to meet upcoming Euro 6 standards beginning in September this year, at least 20 sensors are needed—depending on the engine. The type of engine has an impact on exhaust systems.

ACEEE report recommends steps toward international alignment of heavy-duty vehicle efficiency standards

Green Car Congress

A new report published by the American Council for an Energy-Efficient Economy (ACEEE) recommends the international harmonization of fuel efficiency and/or greenhouse gas emissions standards for heavy-duty trucks and buses. This report explores whether and how heavy-duty standards programs could be better aligned across regions.

Study: US counties with higher PM2.5 concentrations have more stroke deaths

Green Car Congress

Analyzing health data and pollution monitoring information from 1,561 counties across the United States between 2005 and 2010, researchers found the yearly average for fine air pollution ranged from 7.2 The higher the poverty rate and fewer health providers in a county, the greater the health impact of high pollution.
