Annex I Party
Definition
A Party listed in Annex I of the UN Framework Convention on Climate Change: the countries that were OECD members in 1992, plus countries with economies in transition (EITs) including the Russian Federation, the Baltic states and several Central and Eastern European states. Annex I Parties must adopt national mitigation policies and measures and report regularly on them.

Overview
What it means
The annex system operationalises the principle of "common but differentiated responsibilities and respective capabilities" (CBDR-RC). Annex I Parties take the lead in reducing emissions under the Convention's Article 4. 2 and must include specified information in their national communications.
The group is distinct from Annex II (a subset with finance duties) and from non-Annex I Parties (mostly developing countries).
How it is used
Annex I status shapes negotiation blocs, reporting formats and review processes under the Convention and the Kyoto Protocol. In Paris Agreement interpretation, whether the old annex categories map onto "developed" and "developing" is legally debated — the Agreement does not itself use annex lists.
Why it matters
Annex classifications encode the original 1992 fairness bargain of climate law. Understanding them is essential for reading Convention and Kyoto obligations — and for following disputes over whether the binary division still fits a changed world economy.
