The first evidence that exceeding the World Health Organization (WHO) ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke is published today in European Heart Journal, a journal of the European Society of Cardiology (ESC).

Production of meat, dairy and rice are the leading sources of food-related emissions.

A wildfire can pump smoke up into the stratosphere, where the particles drift for over a year. A new MIT study has found that while suspended there, these particles can trigger chemical reactions that erode the protective ozone layer shielding the Earth from the sun’s damaging ultraviolet radiation.

A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements.

Europe’s life science laboratory EMBL is leading the TREC project: the first pan-European and cross-disciplinary effort to examine life in its natural context at unprecedented scales.

The Phlegraean volcanic fields just west of Naples, Italy, are among the top eight emitters of volcanic carbon dioxide in the world. 

Conifers are generally better than broadleaved trees at purifying air from pollutants.

Air toxic emissions from on-road mobile sources are significant contributors to the degradation of air quality in urban and dense population centers. Research led by the United States Environmental Protection Agency (EPA) identified more than 1162 hazardous air pollutants (HAPs) in the exhaust and evaporative emissions from on-road mobile sources.

A new study shows what it will take for the plastics industry to become completely sustainable: lots of recycling combined with the use of CO2 from the air and biomass. 

Carbon dioxide emissions from wildfires, which have been gradually increasing since 2000, spiked drastically to a record high in 2021, according to an international team of researchers led by Earth system scientists at the University of California, Irvine.
