London's Zero Carbon Pathways Tool

Created 2 years ago, updated a month ago

London’s Zero Carbon Pathways Tool shows the ways that carbon emissions might be reduced to net zero by 2050, despite a growing population.

To model London’s current energy consumption and carbon emissions, we have used a detailed information on building type, energy consumption, power demand and capacity, transport activity and emissions from industry. From this baseline, we have run several scenarios for how London’s emissions could reach net zero by 2050:

  • On energy efficiency: The central scenario represents an estimate of how we could reduce energy demand if there is a significant policy effort started immediately. Sensitivities on this assess the impact of delaying or bringing forward these policies, or reaching more or less households, through them
  • On energy systems: we investigated scenarios to reach zero carbon by 2050 through a focus on electrification, decentralised energy, decarbonised gas or a patchwork combination of these
  • On grid decarbonisation: the UK electricity grid has already decarbonised rapidly and the Government’s Green Book projections show that this is likely to continue, but it remains a key factor influencing London’s carbon pathways

Energy and carbon results are presented by sector, as well as some sector specific results such as vehicle kilometres for transport and supply by fuel type for district heat. For each energy efficiency scenario, the implied number of retrofits and heat pump installations are presented. Detailed cost and peak demand impacts have been modelled for the central energy efficiency scenario and all energy systems scenarios. This has been modelled on a pan-London basis so borough level results are an estimate only. Please get in touch for further information on borough specific carbon budgets.
