Researchers at University of Exeter assess the viability of CO2 removal via biomass energy in an EES Perspective article which has just been published online.
The feature article concludes that to maximise feedstocks for biomass energy with carbon storage (BECS) requires more efficient agricultural systems and less meat intensive diets.
