WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. Their paper is published in Atmospheric Environment. That gave them rare, real-world look at pollutant exposure. Earlier post.). the least.

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.

UN Environment report says national GHG pledges only bring one-third of reductions needed for Paris Agreement

Green Car Congress

Even if the current Nationally Determined Contributions (NDCs) are fully implemented, the carbon budget for limiting global warming to below 2 ˚C will be about 80% depleted by 2030. Given currently available carbon budget estimates, the available global carbon budget for 1.5 ˚C C will already be well depleted by 2030.
