# Best Carbon Accounting Software - Page 7 *By [Lauren Worth](https://research.g2.com/insights/author/lauren-worth)* 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 ## G2 Grid® for Carbon Accounting Software ![G2 Grid® for Carbon Accounting Software plotting products by satisfaction and market presence](https://www.g2.com/categories/carbon-accounting/grids.png?focus%5B%5D=1301114&focus%5B%5D=1323049&focus%5B%5D=20026&focus%5B%5D=1868342&focus%5B%5D=143528&focus%5B%5D=169047&focus%5B%5D=1240642&focus%5B%5D=1318221) Highlighted products: osapiens, Watershed, Workiva, Orki, Greenly, Trace, carbmee EIS, and Google Carbon Footprint.
