A 🧵on #Article6 as #COP26 wraps up. A6 is the #ParisAgreement’s engine of international cooperation. It’s vital because countries can cut emissions faster & deeper together than on their own. The decision is not perfect; no text is. But overall it's a step forward. Here’s why.

First, a glossary: ITMO=“internationally transferred mitigation outcome” (btw 2 Parties) 6.4ER=emission reduction under new UN crediting mechanism CORSIA=Carbon Offsetting and Reduction Scheme for International Aviation CA=“corresponding adjustment" to prevent double counting

1/ The guidance has strong provisions against double counting of emissions reductions—the most important safeguard of integrity. It requires CAs for *all* ITMOs (incl. 6.4ERs) that are authorized for use toward NDCs or “other international mitigation purposes” (including CORSIA)

Going into #COP26, the key Qs were: Would CAs be required... ...for GHG reductions from outside an NDC? ...right away? ...for CORSIA & other uses? The answer to all three Qs is: Yes. Countries must account for every ITMO they transfer. That is also a powerful spur for quality.
2/ The text wisely drops the provision cynically pushed by PNG to allow unverified, private-label “REDD-dot-plus” credits. Keeping that text out was vital to ensure environmental integrity and preserve a market for genuinely high-quality REDD+ credits such as #ARTREDD.

3/ The main concern: Clean Development Mechanism credits (CERs) from 2013-2020 can be used for the 1st NDC. estimates that there could be 320m such units; UNFCCC says ~118m. Crucially, pre-2020 CERs must be labeled. Buying countries should refuse to accept them!

4/ Also not ideal: CDM projects can transition to the 6.4 mechanism through 2025. estimates that this could mean ~300mtCO2 of tons from projects like large-scale wind that would keep operating regardless. Again, buyer countries should refuse to accept these.

Bottom line: Parties needed clear guidance on A6 at #COP26; they have it. Text is strong on no-double-counting. The potential is there for A6 to drive greater ambition through cooperation. Buyers must ensure integrity by refusing pre-2020 CERs. Civil society will be watching.

You say CAs are required "...for GHG reductions from outside an NDC?". This would require a host to add-in totals from a project not on its NDC tally, only then for it to be subtracted by the beneficiary. Did I understand correctly and if so, on what basis do you say that?
