A look at N2O: Nitrous oxide emissions may be higher than previously thought

Climate Change News - ENN - June 22, 2015 - 6:01pm
In addition to carbon dioxide there are plenty of other greenhouse gases. Nitrous oxide is one of them. However, a global assessment of emissions from the oceans is difficult because the measurement methods used so far have only allowed rough estimates. Using a new technology for continuous measurements, researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Christian-Albrechts-Universität zu Kiel have now discovered that nitrous oxide emissions from the Southeast Pacific are much higher than previously thought. They publish their data in the international journal Nature Gesoscience.

The Obama administration announced new rules today that would require tighter emissions guidelines for medium and heavy-duty trucks in an effort to reduce greenhouse gases.The rules, proposed by the Environmental Protection Agency and the Department of Transportation's National Highway Traffic Safety Administration (NHTSA), were expected to cut carbon dioxide emissions from trucks and vans by one-quarter by the year 2027.The proposed standards affect semi-trucks, large pickup trucks and vans, buses and work trucks and cover model years 2021-2027, officials said.
