Amid increasing climate-related challenges, businesses and organizations are leveraging data to craft sustainability strategies and global initiatives aimed at reducing environmental impact. Access to comprehensive and transparent environmental data is crucial for researchers to understand and mitigate climate change, yet remains limited. Public web data serves as a valuable tool for governments, businesses, and individuals to achieve environmental, social, and governance (ESG) goals by offering insights into supply chain impacts, air pollution, and carbon intensity, exemplified by projects like those at the UK Turing Institute and Denmark's drone technology for oil spill management. Initiatives such as Subak use shared data to support climate-focused startups and policy changes. Success in combating climate change hinges on global cooperation in data sharing, investing in innovation, enhancing data literacy, and building a culture of collaboration, as emphasized by the commitments made during the COP26 conference.
