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

To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate he has made of the level of reduction the new Ecodesign Regulations for solid fuel burning appliances in domestic premises will have on (a) regulated air pollutants and (b) greenhouse gases.

The new Ecodesign Regulations for solid fuel burning appliances will ensure that the worst-performing and most polluting products are phased out of the market. Therefore, the Regulations will have a positive effect on the average energy efficiency of these appliances on the UK market now that they have come into force.

At the time the new Ecodesign Regulations were agreed, the EU calculated that by 2030 they, along with the associated Energy Labelling Regulations for solid fuel appliances, would result in an estimated reduction in greenhouse gas emissions equivalent to 400,000 tonnes of CO2, which corresponds to 50,000 tonnes of CO2 when scaled to the UK only.

In addition to this the National Atmospheric Emissions Inventory published in March 2021 accounts for the projected impact of the Ecodesign Regulations on regulated air pollutants, specifically PM_2.5. These projections only partially account for the regulations as the emissions factor data at the time of publishing was limited.
