Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, with reference to the Answer of 22 January 2022 to Question 102534 on Firewood: Air Pollution, if he will publish all the research studies to estimate the contribution of domestic wood burning to primary emissions of particulate matter that the Government has commissioned since 1 January 2022.

The contribution of domestic wood burning to primary emissions are estimated in our national atmospheric emissions inventory (NAEI). We publish the methods we use in the Informative Inventory Report and methods document on an annual basis on the NAEI website. The latest report can be found here.

We have commissioned a number of projects to estimate the emissions associated with different solids fuels and appliances and to track trends in domestic burning practices across the UK. The reports will be published in due course.
