### Watershed

Watershed is the enterprise sustainability AI platform. Companies like Airbnb, Carlyle Group, FedEx, Visa, and Dr. Martens use Watershed to measure, report, and act on their emissions—producing audit-ready carbon footprints that drive real decarbonization. Purpose-built AI agents accelerate every step, from data cleaning and emissions factor mapping to report drafting, while embedded climate intelligence and human review ensure results you can stand behind. Named a leader in the Verdantix 2026 Green Quadrant and a CDP-accredited gold solutions provider, Watershed now manages more than 3 gigatonnes of CO2e emissions through our customers. Key features: - Measurement: More than 60 pre-built integrations and a library of 500,000+ emissions factors, benchmarks, and methodologies deliver granular, audit-ready carbon footprints across your entire business—down to individual products and suppliers. - Reporting: Prepare and file sustainability disclosures across global frameworks, including ISSB, CDP, CSRD, TCFD, California SB253/261, and more. AI agents draft reports in the right format using your data, with full data lineage, peer benchmarks, review workflows, and change tracking. - Sustainability AI: Purpose-built AI agents automate data cleaning, formatting, and analysis—getting teams to actionable data up to 80% faster. Watershed Product Footprints uses AI to decompose purchased goods into their underlying materials and processes, so procurement and sustainability teams can compare suppliers, run what-if scenarios, and surface real reduction levers. All AI is built with encoded sustainability intelligence, multi-agent safeguards for accuracy, full transparency into how results are calculated, and human control at every step. - Decarbonization: Develop a sustainability plan, model SBT-aligned targets, and track progress against them. Identify the highest-impact reduction levers across your operations and supply chain. Switch to clean power through virtual power purchase agreements, and access a marketplace of scientifically vetted, high-quality carbon removal and avoidance projects. - Security and compliance: Enterprise-grade API, data governance, user access controls, and SOC 1 and SOC 2 compliance on a cloud-based platform. What Watershed solves: For most companies, the majority of emissions sit in their supply chains—and until recently, that data was either too slow or too imprecise to act on. Watershed gives sustainability and procurement teams a single platform to measure with precision, meet evolving disclosure requirements, and build a credible decarbonization plan. Sustainability AI built on climate science surfaces reduction opportunities that traditional approaches miss, while connecting sustainability data to real business decisions like procurement, energy sourcing, and supplier engagement.

Carbon accounting software helps companies track carbon emissions and implement programs to reduce them through decarbonization. Businesses use this software to improve their environmental protection initiatives and demonstrate their efficiency to interested parties like investors, partners, government agencies, NGOs, and the public.

This type of software is used mainly by industries that produce high emissions, such as manufacturing, oil and gas, mining, transportation, and utilities. Carbon accounting software can also be used by IT companies since hardware, such as servers, produce CO2 emissions. While carbon accounting features may be found in [sustainability management software](https://www.g2.com/categories/sustainability-management) and [environmental, social, and governance (ESG) reporting software](https://www.g2.com/categories/environmental-social-and-governance-esg-reporting), many vendors provide standalone software that offer advanced features such as decarbonization.

To qualify for inclusion in the Carbon Accounting category, a product must:

- Provide features for monitoring carbon emissions from multiple sources
- Create emissions reports that are compliant with carbon regulations
- Allow users to create and analyze emissions scenarios and forecasts
- Deliver decarbonization plans to help companies reduce carbon emissions
- Provide access to marketplaces to buy and sell carbon credits
- Include metrics and analytics specific to carbon accounting
