Study suggests high-mileage light-duty fleets contribute higher emissions and emissions share than expected

Green Car Congress

A study by researchers from the University of Denver and the University of Puget Sound indicates that high-mileage light-duty fleets contribute higher emissions and emissions share than expected based on their actual numbers in the fleet. of the registered vehicles (2000/325000). —Bishop et al.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

Projected changes in summer mean usable capacity of power plants in the US and Europe for the SRES A2 emissions scenario for the 2040s (2031–2060) relative to the control period (1971–2000). This causes downstream thermal pollution affecting, for example, life cycles of aquatic organisms. Source: van Vliet et al. Click to enlarge.
