New Emissions Analytics study suggests pollution from tire wear now 1,850 times worse than exhaust emissions

Green Car Congress

Since that study, which was transparently designed to quantify the worst-case tire emissions under legal driving, Emissions Analytics has been testing and analyzing tire wear emissions in more detail across a wider range of driving conditions, and has performed a detailed chemical analysis of hundreds of new tires.

T&E: tests show cars powered by electrofuels emit high levels of criteria pollutants

Green Car Congress

Proponents claim that if renewable electricity is used and CO 2 is captured from the air, then the e-gasoline and e-diesel are climate-neutral fuels that will also reduce pollution. A 10% blend was chosen due to existing fleet and EN228 standard compatibility. The emissions were compared to the standard E10 EU gasoline.

Poor air quality to remain a problem in India despite pollution control policies

Green Car Congress

in 2030 even if India were to comply with its existing pollution control policies and regulations. The study shows that only about 833 million citizens (about half of India’s estimated population in 2030) would be living in areas that meet India’s National Ambient Air Quality Standards (NAAQS) in 2030. While current ambient PM2.5

Ricardo testing finds DPF regeneration spikes particulate emissions, resulting in exceedance of Euro limits

Green Car Congress

However, current Euro regulations do not apply the legal limit to regeneration tests. The laboratory tests simulated real-world driving and measured a range of pollutants including those which are currently unregulated and difficult to measure on the road, such as ultrafine particles, volatile and semi-volatile particles and ammonia.

EPA tightens national annual PM2.5 standard to 12 µg/m3

Green Car Congress

In response to a court order, the US Environmental Protection Agency (EPA) finalized an update to its national air quality standards for harmful fine particle pollution (PM 2.5 ), including soot, setting the annual health (primary) standard at 12 µg/m 3. This includes an annual standard of 15.0 ?g/m standard of 35?

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.

EPA, NHTSA issue One National Program Rule; EPA withdraws CA waiver for GHG and fuel economy

Green Car Congress

This action is based on the premise that federal law preempts state and local tailpipe greenhouse gas (GHG) emissions standards as well as zero emission vehicle (ZEV) mandates. California’s ability to enforce its Low Emission Vehicle program and other clean air standards to address harmful smog-forming vehicle emissions—i.e.,
