Fermentation turns greenhouse gases into useful chemicals

Physics World

Unfortunately, they are manufactured from fossil resources using highly energy-intensive techniques that release hazardous waste and greenhouse gas (GHG) emissions. As the climate crisis intensifies, researchers are seeking alternative means to lessen the climate impact of producing these commodities.

Greenhouse gas emission impact from peatland fires underestimated by 200%-300%, shows new study

Frontiers

Deforestation fires in Brazil and Indonesia accounted for 3% and 7%, respectively, of the planet’s total greenhouse gas emissions (GHG) in 2019 and 2020, finds a new study in Frontiers in Climate. In Brazil, a total of 11,088 km 2 of forest were destroyed from August 2019 to July 2020. Image: PARALAXIS/Shutterstock.
