Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

In early 2013, the Chinese government declared a war on air pollution and began instituting stringent policies to regulate the emissions of PM 2.5. Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. Over the course of five years, PM 2.5

Study links ambient PM2.5 and ozone specifically caused by vehicle exhaust emissions to ~361,000 premature deaths worldwide in 2010 and ~385,000 in 2015

Green Car Congress

A new study provides the most detailed picture available to date of the global, regional, and local health impacts attributable to emissions from four transportation subsectors: on-road diesel vehicles; other on-road vehicles; shipping; and non-road mobile engines such as agricultural and construction equipment. of global ambient PM 2.5

CARB fines Del Monte $2M for violations of OGV at Berth regulation

Green Car Congress

The At-Berth Regulation is a critical tool for CARB to cut harmful toxic diesel emissions from ships docked in California ports, and we hope this penalty will send a message that violators will pay a hefty price if they fail to comply. The goal of CARB’s At-Berth Regulation is to reduce diesel emissions from ocean-going vessels (OGVs).

New international study finds lab testing of diesel NOx emissions underestimates real-world levels by up to 50%

Green Car Congress

A new international study has found that laboratory tests of nitrogen oxide emissions from diesel vehicles significantly underestimate the real-world emissions by as much as 50%. Real-world NO x emission factors by vehicle emissions standard in key regions. A paper on the work is published in the journal Nature.

EPA issues ANPR on Clean Trucks Initiative, seeking input from public and stakeholders

Green Car Congress

The eventual CTI rulemaking will establish new, more stringent emission standards for NO x and other pollutants for highway heavy-duty engines. This rulemaking will also offer opportunities to streamline and improve certification procedures to reduce costs for engine manufacturers.

EPA launches Cleaner Trucks Initiative to update NOx standards for heavy-duty trucks

Green Car Congress

The US Environmental Protection Agency (EPA) has launched the Cleaner Trucks Initiative (CTI) to further decrease NO x emissions from on-highway heavy-duty trucks and engines. The US has made major reductions in NO x emissions, but it’s been nearly 20 years since EPA updated these standards.

US EPA proposing allowing high-octane, higher ethanol content fuels as part of Tier 3 regs; E30 as example

Green Car Congress

Higher octane fuels can lead to higher compression ratios which in turn can lead to more efficient gasoline engines and reduced fuel consumption. With turbocharged gasoline engines, there is a double benefit: higher compression ratios and increased boost. such a fuel would result in equivalent emissions performance.
