ecbi has published its 2023 Annual Report. The Bonn Seminar, Fellows Colloquium, and Oxford Seminar took place during the report period, covering a range of issues of relevance to the intergovernmental climate negotiations, such as the Global Stocktake, climate finance particularly for loss and damage, and Paris Agreement Article 2.1.c on making financial flows consistent with the goals of the Paris Agreement. ecbi also published a report assessing Key Outcomes from COP27, as well as an Updated Pocket Guide on the Paris Agreement. Other ecbi publications, including discussion notes, policy briefs, and blog posts, addressed, among others, a proposed climate solidarity levy to help fund the response to loss and damage. In addition, ecbi Director Benito Müller presented at numerous events, including at COP27, promoting the idea of climate solidarity levies, which, he said, could come in the form of levies imposed on air tickets and/or shipping containers, and which could help capitalise the newly-established loss and damage fund. The report includes reflections from Müller on the untimely passing of ecbi co-founder Salemul Huq, who headed ecbi's Training and Support Programme though the International Centre for Climate Change and Development (ICCCD).
