Biomass Strategy 2023: Cross Sectoral Sustainability Framework

Baroness Sheehan Excerpts

Wednesday 15th November 2023 Lords Chamber

[Baroness Sheehan (LD)]

My Lords, I declare at the outset that I have a biomass boiler, which came with the house I live in—but, honestly, we are trying to get rid of it. It takes trees between 44 and 115 years for sequestration of carbon. The lower estimate takes us well beyond 2050, the upper beyond the lives of anyone born today. So clearly biomass is not renewable within the timeframe needed to tackle climate change. Will the Government take that into account and ensure that the UK applies the precautionary principle and ends the ridiculous classification of biomass as a renewable power source?

[Lord Callanan (Con)]

I am pleased to hear that the noble Baroness has a biomass boiler. In fact, she does not need to get rid of it, because if she sources her pellets from the appropriate sources, that is a renewable resource. These are not pellets from virgin forests but by-products from the timber production process. There are very strict sustainability criteria attached to them and, even if those pellets were not used for biomass production, they would be a waste product because the timber would still be harvested for its other uses. So the noble Baroness does not need to feel so guilty.

--- Later in debate ---

[Lord Callanan (Con)]

I am not sure I know what third and fourth generation biomass is. I will have to have a cup of coffee with noble Lords afterwards and we can have a chat about it.

[Baroness Sheehan (LD)]

Does the Minister agree that trees decompose only once they are felled?

[Lord Callanan (Con)]

I suppose, if we want to get into a debate about that, they absorb CO₂ when they are growing. If they are felled and just rot on the ground they emit CO₂, but also when they are burned.
