We will put affordability and fairness at the heart of our reforms to reach net zero. Our latest estimates put the costs of net zero at under 2% of GDP—broadly similar to when we legislated for it two years ago—with scope for costs of low-carbon technologies to fall faster than expected. Most of those represent increased investment in growth markets of the future. However, I take my hon. Friend’s point. All I would say is that he should wait until the net zero review is published.
