Study estimates California’s GHG reductions since 2003 could be wiped out by 2020 wildfires

Green Car Congress

In an open-access report in the journal Environmental Pollution , researchers from UCLA and the University of Chicago estimate that California’s wildfire carbon dioxide equivalent (CO 2 e) emissions from 2020 (~127 mmt CO 2 e ) are approximately two times higher than California’s total greenhouse gas (GHG) emission reductions since 2003.

China-based study concludes using political incentives to fight pollution is costly and inefficient

Green Car Congress

The study looked at water quality regulations and found that local officials more heavily enforced regulations on polluting firms that were monitored and tracked by the central government, while not enforcing regulations on firms not tracked. A 10% reduction in pollution led to a 3% drop in productivity for China’s polluting industries.

Study finds rapid increases in nitrogen oxides may be as harmful to the heart as sustained levels

Green Car Congress

Rapid increases in pollution may be as harmful to the heart as sustained high levels, according to new research published in the European Journal of Preventive Cardiology. However, this study investigated whether rapid increases in pollution increase the risk of heart attack, independently of an absolute threshold.
