This year saw the release of new detail on the Government’s plans for Net Zero with the publication of the Carbon Budget Delivery Plan (CBDP) prompted by last year’s High Court judgement. But policy development continues to be too slow and our assessment of the CBDP has raised new concerns. Despite new detail from Government, our confidence in the UK meeting its medium-term targets has decreased in the past year. The increased transparency embodied in the CBDP is welcome, but a key opportunity to raise the overall pace of delivery has been missed.
