Methane Emissions

Baroness Blackstone Excerpts

Wednesday 22nd February 2023 Lords Chamber

Asked by

[Baroness Blackstone]

To ask His Majesty’s Government, further to their commitment to the Global Methane Pledge launched at COP26, what plans they have to set a target for reducing methane emissions by 30 per cent on 2020 levels by 2030.

[The Parliamentary Under-Secretary of State, Department for Energy Security and Net Zero (Lord Callanan) (Con)]

My Lords, the UK has adopted early and ambitious measures to tackle methane emissions. Between 1990 and 2020, UK methane emissions dropped by 62%, more than any other OECD country. The Government recognise the urgency to do more and are pursuing efforts to secure further emissions reductions in line with the net-zero strategy and our carbon budgets. The Government’s approach is consistent with the global methane pledge as a global reduction target.

[Baroness Blackstone (Lab)]

My Lords, I am grateful to the Minister for his Answer, but I am not absolutely sure whether he is saying that the UK itself is committed to a 30% reduction, or whether it is just taking part in a collective reduction. Can he clarify that? I also want to ask him about the vexed problem of landfill sites, where we are still capturing only 70% of the biogas coming from them—and the proportion has declined since 2016. How will the Government increase methane capture rates to nearer 90%, as happens in some sites, by both reducing greenhouse gas emissions and harvesting more useable gas for the economy? If he does not know the answer to these questions, can he write to me?

[Lord Callanan (Con)]

I do know the answers to the noble Baroness’s questions, she will be shocked to know. In answer to her first question, I say that the UK is signed up to, and helping to implement, a global target. On the waste sector, she is absolutely right that we need to do more. Landfill emissions over the last 25 years have been tackled in two ways: by reducing the amount of biodegradable waste going to landfill, with the landfill tax being a key driver, and by increasing the efficiency of methane collection from existing landfills. The other thing we need to do more is to increase waste food collections, so that we can generate more clean gas through anaerobic digesters, which is part of my department’s policies.
