Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, with reference to page 26 of the research paper by Chatham House entitled BECCS deployment: the risks of policies forging ahead, published in October 2021, if she will make an assessment of the implications for her policies of that paper's findings on the carbon payback period of a mature tree; and whether her Department has made an estimate of the carbon payback period for unabated wood burning.

The Government views sustainably sourced biomass as low carbon, in line with independent organisations such as the CCC and IPCC, as set out in the Government Biomass Strategy, published in August 2023.

Only biomass that complies with strict sustainability criteria receives support from Government. For forest derived biomass, the criteria includes requirements around sustainable forest management including regeneration rates and sustainable harvesting, requiring that the carbon stock of the forest is not decreased.

In 2024, Government will consult on a cross sectorial sustainability framework to see where we can strengthen the criteria further based on latest evidence.
