The new #NetZeroStrategy from @GOVUK:

gov.uk/government/pub…

Here are all the key commitments in one 🧵...
Power
Fuel supply and hydrogen
Industry
Heat & buildings (lots here!)
Transport
Natural resources, waste & F-gases
Greenhouse gas removal
Thoughts to follow, especially on that last topic ;)

A thread on one of the new bits in the #NetZeroStrategy: greenhouse gas removals (GGR)...
There are many ways to do removal. @GOVUK splits them between biology (e.g. trees and soils, which it puts in the “Natural Resources” part of its strategy) and engineering.

Here I’ll focus on the engineered ones, but the biological ones are worth a thread, too 🌲🌳🟫
The strategy lists these specific engineered removal approaches as deployable: BECCS, DACCS, wood in construction, enhanced weathering and biochar.

On the day the UK's #NetZero strategy is due out, including a strategy on GHG removal, I'm pleased to share this job opportunity:

bit.ly/3aRAHuY

Come work with us on economic policies and incentives for removals, @TheSmithSchool as part of @CO2REhub
It's a 2yr postdoc position, working with the likes of @SamFankhauser, @ElizBaldwin, @abhaney, @camjhep, me and the wider @CO2REhub team...
Incentives are one of *the* key things missing to scale GHG removal successfully - and this is vital for achieving #NetZero (alongside cutting emissions, obvs).

It was a pleasure to be on the Advisory Group for this report by the National Infrastructure Commission. Well done to the author team!

A few brief thoughts... 🧵
While about "engineered removals" this report focusses quite specifically on two approaches: bioenergy with carbon capture and storage (BECCS) and direct air carbon capture and storage (DACCS).
As people say, "other brands are available" (e.g. trees, soil enhancement, enhanced weathering of minerals, non-energy uses of biomass such as biochar, construction...)

So there have been a couple of carbon removal developments in the UK today, although they haven't been spelled out together so here we go... 🧵
First, UKRI has announced a new research programme including a national hub (which I am a part of) and 5 carbon removal demonstrators.

Demos will be on:
* trees 🌲🌳
* peatlands 🏞️
* biochar ◾️
* energy crops 🌿
* enhanced rock weathering 🪨

Second, @BEISgovuk has announced 24 carbon removal innovation projects with commercial partners.

Lovely to see coverage today of our report on the quantity & quality of #NetZero targets around the world: netzeroclimate.org/innovation-for…

There are excellent threads already by co-authors @_richardblack and @thomasnhale (check them out). Just a few additional thoughts from me...
1. 2050 is a strong anchor date for these targets (not surprising given the IPCC Report on 1.5°C). The huge post-2050 chunk we see for countries is solely down to China. Quite a few states and companies are aiming earlier.
2. Despite countries having the most well-developed climate governance (the UNFCCC), those with #NetZero goals still by no means have it all in place. Companies are doing similarly well on setting plans and reporting at least annually.

How to manage the inclusion of carbon dioxide removal (CDR) measures in climate targets? I have a comment on it out today in @CommsEarth:

nature.com/articles/s4324…

It's open access, but here's the Twitter-friendly version...🧵
Several papers and reports have flagged that "net-zero" targets allow some level of CDR to balance out residual emissions, and worry that this could dilute action in various ways. They propose that the way to fix this is to keep separate targets for emissions and removals.
This isn't a theoretical argument, it's live now. The UK and other have set net zero targets; the EU is actively thinking about whether/how to include CDR.
