As extreme weather becomes more frequent and severe, climate-related damages will increase, particularly within the least resilient economies that typically have the lowest carbon footprint. COP27 saw the framing of the UN’s Loss & Damage (L&D) fund to compensate for damage stemming from climate change. This presentation will outline Ortec Finance’s practical approach towards how the L&D could be executed to allow funding to commence and the important role open source could play in such an intertwined and complex resolution, showcasing Open Source Climate (OS-Climate) as an example of community collaboration in the field of physical climate risk and resilience. The ideas are developed in a recent Nature Comment: Climate loss-and-damage funding: a mechanism to make it work (nature.com,
