Sweep is an enterprise carbon and sustainability management platform used by large companies to measure their emissions, cut them, and report the results to regulators and investors. It is built for the whole value chain, so it handles the hardest part of carbon accounting: Scope 3 emissions from suppliers.
It was founded in 2020 and is led by CEO Rachel Delacour, who previously built the business-intelligence company BIME Analytics (acquired by Zendesk). Sweep has raised roughly $100 million from investors including Coatue and Balderton Capital, is a certified B Corp, and in 2026 was named a Leader in both the Verdantix Green Quadrant and the IDC MarketScape for enterprise carbon and ESG software.
Below: what Sweep does, the regulations it covers (CSRD, California SB 253, ISSB, CDP), its features, pricing, pros and cons, and how it compares to alternatives.

What is Sweep?
Sweep organizes carbon and ESG work around three stages: track emissions across your operations and supply chain, disclose them in the formats regulators and frameworks require, and act by setting targets and modelling reduction scenarios. It pulls activity data from across the business, applies emission factors, and turns the result into audit-ready reports.
Because it was built for large organizations, it emphasizes collaboration: different teams, business units, and suppliers all work in the same system instead of emailing spreadsheets back and forth.
It also includes an AI assistant to speed up data collection and analysis, and it connects to a marketplace of vetted carbon-reduction and offset projects. Sweep is one of the more established carbon accounting software platforms, working with companies such as L’Oreal, Orange, SNCF, Ubisoft, and Swisscom.
Regulations and frameworks Sweep supports
