Incentives are one of *the* key things missing to scale GHG removal successfully - and this is vital for achieving #NetZero (alongside cutting emissions, obvs).
You may have noticed we are on something of a hiring spree at the moment. We really hope to build an exciting, diverse and multi-disciplinary team of early-career researchers, advancing this field in the UK...
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.
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...)
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.
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.
