Greenhouse gas emissions from burning US-sourced woody biomass in the EU and UK

This paper examines one particular source of woody biomass: pellets sourced from the US that are burnt for electricity and combined heat and power in the EU and UK. Accounting for emissions from their combustion, their supply chain, forgone removals of carbon dioxide from the atmosphere due to the harvesting of live trees and emissions from the decay of roots and unused logging residues left in the forest after harvest, it finds that US-sourced wood pellets burnt in the UK were responsible for 13 million–16 million tonnes of CO2 emissions in 2019, equivalent to the emissions from between 6 million and 7 million passenger vehicles.
