UK government today unveils some new detail on plans to support greenhouse gas removal:



A good step forward for supporting CCS-based removal methods. Still some details to iron out... (1/6)gov.uk/government/pub…
Key points:
* the plans follow the "contracts for difference" model which has worked well for scaling renewable power in the UK
* 15 yr contracts
* an approach to defining cost elements eligible for inclusion...

(2/6)
* a review published of standards and methodologies:

Will be worth a read, but still work to do on deciding how removals will actually be measured...

So, what were the developments in carbon removal at #COP27?

A thread picking out some points across equity, innovation, reporting & accounting, and the texts...🧵
Equity:

On the one hand, carbon capture & storage (CCS) was in discussions, pushed mainly by fossil fuel interests. CCS on fossil fuel isn't carbon removal, but the same infrastructure applies. Inherited skepticism is therefore a real issue for removals.

On the other hand, the draft cover text initially included a call for developed countries to go net negative by 2030:

unfccc.int/documents/6241…

Obviously it didn't last, but it shows that "beyond zero" is now part of the discussion around fairness.

UNEP Emissions Gap Report out today.

unep.org/resources/emis…

Headline: the gap is very much still there!

But also... (1/n)
Lots of countries have been pledging to go #NetZero in the longer term. This year's report has a chapter zooming in on these #NetZero targets. Here are some key messages...
1. If we want to limit climate change to 2°C, 1.5°C, or any other level for that matter, we need global #NetZero.

Meeting the 1.5°C limit implies getting there for CO2 around 2050.

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...)
