In July, climate experts raised concerns to the new Labour government about the slow progress in reducing carbon emissions. The UK aims to achieve net zero by 2050, but the Climate Change Committee (CCC) reported that only a third of the necessary actions to reach the target of a 68% reduction in greenhouse gas emissions by 2030 were covered by credible plans. This puts the UK off track for net zero.
The London Assembly’s environment committee also received warnings that Sadiq Khan’s goal of achieving net zero in London by 2030 may be at risk. While there has been significant progress in reducing emissions by 50% compared to 1990 levels, the focus now needs to shift to decarbonising buildings and transport in the capital.
Buildings and transport are the main challenges in London when it comes to reducing greenhouse gas emissions. Mayor Khan’s ambitious target requires extensive efforts such as properly insulating two million homes, installing 2.2 million heat pumps, connecting 460,000 buildings to clean energy heating networks, transitioning to a net-zero bus fleet, and setting up 40,000 electric vehicle charging points within five years.
The estimated cost of making all 3.8 million homes in London energy efficient is £49 billion, and an overall investment of £75 billion by 2030 will be needed. While City Hall plays a significant role, collaboration with central government and private investors is crucial. The CCC emphasized the importance of urgent action to get the country back on track towards achieving net zero.
Efforts are underway to address the challenges. Transport for London is seeking investors for solar farms to power the London Underground network, while solar panels are being installed at the London Stadium using financing from the Green Finance Fund. Plans for low-carbon heat networks in central London and other areas are also in progress with government funding support.
In addition to specific projects, the recent restructuring of Khan’s London Partnership Board aims to coordinate city-wide action on climate change. The board brings together various stakeholders to drive collective efforts in tackling the climate emergency.
Despite the progress made, challenges remain in decarbonising buildings and transportation in London. Urgent and coordinated action is necessary from all levels of government and private sectors to meet the ambitious climate targets. It is crucial to continue raising awareness, investing in sustainable solutions, and working together towards a greener future for London and the UK as a whole.
