# 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.
