Patch

Patch is a climate platform that helps companies source, buy, and manage carbon credits and removals, offered both as a self-serve platform and as an API. Through Patch, a business can browse a catalog of vetted projects spanning nature-based removal, engineered removal like direct air capture, and avoidance credits, filter by price, delivery timing, and quality criteria, purchase credits, and then track and retire them with documentation suitable for sustainability reporting. The API lets developers build carbon purchasing directly into their own products and workflows, for example adding climate contributions at checkout, in expense and travel tools, or in logistics software, by passing an amount or an emissions estimate and receiving completed orders back. In 2025 Patch launched an expanded platform that combines its marketplace with data, a climate science advisory team, and AI tooling to help buyers develop a strategy and navigate a fragmented market, and it built a database covering tens of thousands of projects across major registries. Patch is aimed at corporate sustainability teams and at companies embedding climate action into customer experiences. It is sold as a paid platform, earning fees on credit transactions and offering subscription tiers for platform access, advisory support, and API usage.
