So, what to make of it all? It's pretty good, no? https://www.businessgreen.com/news/4023559/government-promises-unleash-net-zero-investment-blitz-point-plan-green-industrial-revolution

Again, here is the Prime Minister of one of the world's largest economies, the crucible of the first industrial revolution, essentially saying the fossil fuel age will be over before most people under 40 have retired. You can't get away from how significant that is.

And more than that, he's saying within 10 years the majority of the UK's power will come from offshore wind and the age of the internal combustion engine will be over.

Plus, there's a plan to achieve all this (sort of). Significant chunks of funding for CCS, hydrogen, nature, energy efficiency, and especially EVs, plus very imminent policies for nuclear, renewables, etc.

But, of course there's a but. It is hard to get round the fact £12bn (only £4bn of which is new) is significantly lower than the sums being mobilised by Germany and France.

Yes, there's differences in accounting, but look at the multi-billion sums being pumped into hydrogen in France, Germany, and Japan compared to the 'up to £500m' for hydrogen in the UK. Look at the £20m funding for green maritime R&D. Too many parts of the plan look underpowered.

The plan looks very good on the stuff the UK is good at - offshore wind, EVs - but it looks light on the really hard stuff. Energy efficiency funding is still badly underpowered, so is green aviation and maritime, so is nature.

It's understandable - no one has solved this big gnarly problems - but if the government wants to leverage in private sector finance to make progress in these really difficult areas then the Treasury needs to send big serious signals.

Again, it is starting to do that and this is undoubtedly a horrendous fiscal climate. But if you really want to turbocharge a green recovery now is the time to borrow to invest. Invest in energy efficiency, in sustainable jet fuels, in CCS, etc, at serious scale.

Overall though, it is an exceptionally good plan filled with strong investment signals. Private capital is already flooding in and a lot more will do so. It will up the pace of decarbonisation and create lots of green jobs. It is a step change in political engagement from the top

But it is a starting point and now the onus is on individual departments and businesses to build on it. To remove the barriers to investment, to deliver the just transition plans, to engage the public. Basically, to get on with it.

One coda to this. The plans obviously aren't advanced enough, but it would have been great to have one big funding commitment behind something really eye-catching, like @drvox proposal this morning to electrify every school bus in the US. The UK could and should do that ASAP.

In conclusion and on balance...
