On Friday 19 May, the National Audit Office (NAO) published Support for innovation to deliver net zero. The report looks at whether the government is set to deliver value for money from its approach to investment in research and innovation to deliver net zero. It found that the government had made progress in recent years but that more needs to be done to ensure that investments are value for money. The NAO recommends that the Net Zero Innovation Board should specify the desired outcomes for each of the challenge areas in the Net Zero Research and Innovation Framework and define what level of failure is tolerable. This should include publishing update reports against the output and outcome targets for each challenge – for example, the potential for reductions in carbon emissions and the amount of private investment.
