Welcome back! It is now week two at COP30. Ministers from around the world have arrived in Belém to participate in the COP High-Level Segment and help guide the negotiations to completion.
Three more updated nationally determined contributions (NDCs) have come in since our last update, from Costa Rica, Mexico, and Yemen. One trend is emerging in new NDCs: more countries are committing to a range (rather than a specific number) of emission reductions. For example, the EU’s commitment is to reduce net greenhouse gas emissions 66.25-72.5% by 2035 compared to 1990 levels. The Alliance of Small Island States (AOSIS) is leading an effort to urge countries to meet the upper end of their targets. AOSIS also underscores that many developing countries can only meet their full NDC commitments with international climate finance.
If you are looking to get caught up on week one of COP30, our newsletters from last week, as well as this excellent Halfway Point Webinar from the Earth Negotiations Bulletin, would be great places to start.
