Estimates Day debate on the spending of the Department for Energy Security and Net Zero on energy infrastructure

On Wednesday 5 July MPs will debate the spending of the Department for Energy Security and Net Zero on measures relating to energy infrastructure. 

The Department for Energy Security and Net Zero (DESNZ) is responsible for: 

• delivering security of energy supply 
• ensuring properly functioning energy markets 
• encouraging greater energy efficiency 
• seizing the opportunities of net zero to lead the world in new green industries. 

The department works with 14 agencies and public bodies. 

The UK has adopted a net zero carbon emission target for 2050, making it the first major economy to pledge to cut emissions to zero. This will trigger a profound economic shift in the country and the Estimate for the Department includes a £790 million increase in budget for Net Zero.  

The DESNZ Estimates memorandum (PDF) published alongside the Main Estimate 2022-23 contains a detailed breakdown of the department’s spending. This includes information on spending controls and key drivers of spending changes since last year.  

The Climate Change Committee (CCC) is an independent, statutory body that advises the UK government and devolved administrations on emissions targets. On 28 June 2023, the CCC published its 2023 Progress Report to Parliament on progress made in reducing greenhouse gas emissions and preparing for and adapting to the impacts of climate change. 

This briefing provides background information for the debate and also parliamentary and media coverage of the issues.
