In the inaugural episode of the OSS Climate Podcast, host Richard Littauer chats with our first guest, Koen Hufkens, the founder of BlueGreen Labs. They talk about the use of open source tools to address climate change issues, the role of community science, and the responsibility of open source maintainers towards their users. Koen also discusses the challenges of maintaining open source software, the impact of the European Union’s Cyber Resiliency Act on small-scale developers like him and highlights the importance of contributing to a solution for the current climate crisis.
