Researchers use satellite data to show vehicles are an under-recognized source of urban ammonia pollution

Green Car Congress

By disrupting normal societal activities such as driving, COVID-19 lockdowns afforded a unique opportunity to study their impacts on the environment. On a national or global scale, most NH 3 pollution comes from agricultural sources, such as livestock manure. The team analyzed satellite readings of NH 3 , as well as NO 2.

Study finds some improved cookstoves may emit more black carbon pollution than traditional mud cookstoves

Green Car Congress

The variation in performance among the five ICs tested in this study should raise caution about IC assumptions and terminology, particularly as some so-called “improved” stoves in the natural draft category may at times perform even worse than a traditional mud cookstove. —Kar et al.
