GitHub and the Yale Program on Climate Change Communication surveyed opted-in GitHub users in spring 2026. 80% want energy-efficient coding tools, 74% want ways to measure their software's impact, and 71% are concerned about AI's environmental footprint. Only 10% think their current practices meaningfully reduce impact. The report recommends starting with measurable waste in code, data, I/O and frontend performance. The sample is marketing opt-ins, so the numbers skew toward engaged users.
