Atmospheric chemistry: Are plant emissions green?

Alex Guenther1

Top

Hydrocarbon emissions from living vegetation are thought to be harmful to the atmosphere. But the latest study suggests that the negative impact of these emissions in pristine environments is less than expected.

Do trees produce more pollution than cars? Terrestrial vegetation produces copious quantities of hydrocarbons and other volatile organic compounds (VOCs) that dominate global gas emissions.
