In the introduction to your 2022 report “London Net Zero 2030: An Updated Pathway” you write that that report “will help us communicate with Londoners about what is involved in reaching net zero. There is great public support for climate action, but we need to build public consensus around the specific policies to get us there. This report is an important contribution.” During London Climate Action Week in June 2025 you made a series of public statements, speeches, and announcements – which of the “specific policies” set out in your 2022 report did you communicate to Londoners or attempt to...

You are still committed to your “London Net Zero 2030: An Updated Pathway” plan to achieve carbon net zero by 2030. This plan states that a pay-per-mile road user charging (PPM) scheme is “required” to deliver your climate target to reduce road traffic. But you also state that you will not introduce PPM. Will you also rule out a clean air charge: a low-level daily charge across all of Greater London for all but the cleanest vehicles?

This plan states that a pay-per-mile road user charging (PPM) scheme is “required” to deliver your climate target to reduce road traffic. But you also state that you will not introduce PPM. Will you also rule out a Greater London boundary charge, which would charge a fee to non-London registered vehicles entering Greater London?

Your “London Net Zero 2030: An Updated Pathway” plan to achieve carbon net zero by 2030 includes a target of “2.2 million heat pumps in operation in London by 2030”. By my estimate, this would require a major increase in electricity generation and distribution across London, in the order of 2 Hinkley Point C-size nuclear reactors, or a similarly extremely large-scale deployment of solar or wind generation. Assuming that this additional electricity can be generated, what actions have you taken to ensure that the power grid in London can cope with this extra load, as required by your Net Zero...

Your “London Net Zero 2030: An Updated Pathway” plan to achieve carbon net zero by 2030 includes a target of “2.2 million heat pumps in operation in London by 2030”. This number of heat pumps would require a major increase in electricity generation and distribution across London especially on peak winter days, by my estimate in the order of 2 extra Hinkley Point C-size nuclear reactors, or a similarly extremely large-scale deployment of solar or wind generation. How do you believe this additional electricity will be generated and are you confident that the extra electricity generation required by your Net...

Prior to adopting a net zero target for London of 2030, your target was 2050. When updating your target in 2022 regarding heat pumps you noted that, referring to the previous 2050 target, “The previous trajectory in the 1.5°C Plan said that by the mid-2020s, 160,000 homes would need to be retrofitted [with a heat pump] each year, 900,000 heat pumps would need to be installed by 2030”. Since we are now in the mid-2020s, how close are you to the 160,000 annual heat pump installations? I assume you are well ahead of it, since you dropped this 1.5C plan...

Your “London Net Zero 2030: An Updated Pathway” plan to achieve carbon net zero by 2030 includes a target of “2.2 million heat pumps in operation in London by 2030”. We are now 3 years into your 8 year plan which notes that this target requires “280,000 heat pumps installed annually at the peak deployment” which it states will occur in 2026. How many heat pump installations do you forecast will occur in London in 2026?
