On the topic of carbon budgets, you've heard the back-and-forth with the minister comparing the U.K.'s carbon budget approach to the approach he chose to take with climate targets. I believe the words he used were “dancing on the head of a pin”. Maybe “potato, potahto” would be a better comparison.
I'm wondering what your perspective is on this. Are these essentially similar approaches just phrased differently, or are there key substantive differences between the carbon budget approach and the climate target approach?
