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.

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

Green Car Congress

Testing of two popular Euro 6d-temp diesels by Ricardo, commissioned by the environmental NGO Transport & Environment (T&E), has found that the periodic regeneration of diesel particulate filters (DPFs) in the light-duty vehicles can generate spikes of particulate emissions of more than 1,000 times the normal rate.

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.,

CARB settles with American Honda Motor for $6.9M for violations of air quality regulations on small off-road engines

Green Car Congress

In 2019, CARB testing revealed several small off-road engine (SORE) products did not meet CARB evaporative emission standards. These standards control the amount of raw fuel that is allowed to evaporate from these engines, which are typically used in lawn and garden equipment such as lawn mowers and pressure washers.

Engine products group files legal challenge to EPAs partial waiver for E15

Green Car Congress

Yet, E-15 has been shown to adversely affect engines in non-road products and later model year vehicles, cause emission failures and increase air pollution due to misfueling, the group says. We want to be sure that any new fuel will not increase air pollution, harm engines or endanger consumer safety. Earlier post.).

California ARB approves ACC II rule; 100% of LDVs to be PHEVS, ZEV by 2035; LEV IV emissions requirements

Green Car Congress

The rule establishes a year-by-year roadmap so that by 2035 100% of new cars and light trucks sold in California will be zero-emission vehicles (ZEVs) and plug-in hybrid electric vehicles (PHEVs). It does not impact existing vehicles on the road today, which will still be legal to own and drive.
