The Comptroller & Auditor General has disclaimed the Whole of Government Accounts for 2023-24.

This is due to a lack of audited accounts for English local authorities, with only 4% of these bodies producing audited accounts.

Read the C&AG's opinion here: www.nao.org.uk/reports/whol...
“It’s essential that the Government’s reforms to the local government audit system in England are effective in restoring timely and robust assurance in that sector so that the accuracy of the UK’s Whole of Government Accounts can be properly assured. Even more importantly, local taxpayers in England deserve timely audited accounts from their local council.” Gareth Davies, Comptroller & Auditor General, National Audit Office

The UK Emissions Trading Scheme plays an important part in helping the UK meet its net zero ambitions. But the UK's low price for carbon allowances, and a lack of investment opportunities for low-carbon tech could undermine the Scheme.

Our report: www.nao.org.uk/reports/uk-e...
How the UK Emissions Trading Scheme incentivises decarbonisation Scheme participants and other market traders can trade allowances with each other on a secondary market. Participants that can reduce emissions can sell allowances to participants with emissions in excess of their allowances. The value of allowances on the market sets a carbon price - £37 the Scheme's average carbon price in 2024. Over time, participants are incentivised to reduce emissions by investing in new low-carbon technology as this becomes preferable to paying the carbon price for emitting carbon. 11 million tonnes: total reduction in emissions in the three sectors covered by the Scheme, 2021 to 2023. IMAGES: in the centre of the page. A single ticket saying 'one allowance', with four factories surrounding it. There are double headed arrows between each factory. Next to this image are two wind turbines atop a hill.
