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

Green Car Congress

Specifically, in this action, NHTSA is affirming that its statutory authority to set nationally applicable fuel economy standards under the express preemption provisions of the Energy Policy and Conservation Act (EPCA) dictates that such state and local programs are preempted. criteria pollutants—is not affected by the action.

CARB releases results of multi-year E15 study; multiple air quality benefits with slight reduction in fuel economy

Green Car Congress

The test fleet showed statistically significant effects for some pollutants, but not for others. NO x emissions, a target pollutant of concern for this program, did not show any statistically significant difference between the fuels for the FTP nor for each individual FTP phase.

Embark and HP introduce EV drayage within autonomous truck operations

Green Car Congress

This EV drayage pilot gives HP the ability to leverage electric trucks—which currently have a driving range best suited for drayage operations—in a meaningful way within its supply chain, seamlessly complementing the efficiencies provided by Embark-equipped autonomous trucks, which are 10% more fuel efficient than human-operated trucks.

MIT study finds air quality co-benefits of US carbon policies can significantly offset costs, depending upon the policy

Green Car Congress

In fact, policies aimed at cutting carbon emissions improve air quality by a similar amount as policies specifically targeting air pollution. The study is the most detailed assessment to date of the interwoven effects of climate policy on the economy, air pollution, and the cost of health problems related to air pollution.

MECA report finds additional NOx emission reductions from new heavy-duty trucks achievable and cost-effective

Green Car Congress

NO x is a precursor for both ground level ozone and secondary PM 2.5 A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks. —MECA Executive Director, Rasto Brezny.

Study finds air quality models significantly underestimate traffic as source of NOx in Europe

Green Car Congress

It has been a challenge to determine how much each polluter contributes to the emission output. However, the amount of pollutant emissions that vehicles emit on a daily basis depends on numerous factors, for example on individual driving behavior. —Karl et al.

Report argues advanced HD natural gas vehicles foundational for California to hit air and climate goals; near zero-emission potential

Green Car Congress

Compared to the 2010 “Business as Usual” scenario—which includes all adopted emission control measures for the South Coast—NO x levels must be reduced by 65% and by 75% to meet the 2023 and 2032 ozone standards, respectively. An 80% reduction of GHG emissions is targeted for 2050, relative to 1990 levels.
