Doing nothing is more expensive than investment to reach zero carbon. The UK Government investment is led by the Treasury, which is deliberately excluded from having to consider climate change in its decisions. This was something the Lords tried to amend in the Environment Bill, but MPs rejected the idea.
Pre-COP26 we have a budget that makes domestic flights cheaper and once again, stops the fuel duty escalator from going up as it was meant to do to discourage driving. The result is that it is often cheaper to fly than take the train, and cheaper to drive than take the bus.
The chancellor has also continued to subsidise fossil fuels and to encourage exploration everywhere from the North Sea to the Isle of Wight.
I suggested the Treasury borrow some Green Party economists.
