ClimateLedger is a blockchain-powered platform designed to provide immutable and transparent verification of climate-related claims, investments, and project impacts. It addresses the growing issue of “climate deception” and the “trustworthiness gap” in the green energy sector by allowing companies, governments, and consumers to track and verify environmental performance, carbon footprint reductions, and renewable energy project outcomes. Users can upload data from sensors, energy meters, and certified audits, which is then timestamped and secured on a distributed ledger, making it auditable and resistant to manipulation. This helps expose greenwashing, build trust in genuine climate initiatives, and provides concrete, verifiable evidence for legal or regulatory actions, as well as for transparent reporting of climate change costs and benefits.
