That is the central finding from a new survey of 1,039 GitHub users conducted by GitHub and the Yale Program on Climate Change Communication.

This ProductLaunch is relevant to the technology intelligence record because it involves GitHub. The source article should remain the factual reference for follow-up coverage.

• That is the central finding from a new survey of 1,039 GitHub users conducted by GitHub and the Yale Program on Climate Change Communication.
• Eight in 10 respondents said they were interested in tools that help them write more energy-efficient code.
• Nearly as many wanted best practices for reducing software’s environmental footprint, and almost 75% wanted ways to measure the impact of their software or development process.
• There is an opportunity to turn that interest into normal engineering work: identify unnecessary compute, propose a change, test it, and let maintainers decide what ships.
• Developers care about climate change and AI’s environmental impact The survey, drawn from GitHub monthly active users in the United States, asked about climate change, AI, software efficiency, and the responsibilities of organizations across the technology sector.
