Frequently asked questions

What is ESG software?

ESG software collects environmental, social and governance data across an organization and helps report it against disclosure frameworks and regulations.

What is the difference between carbon accounting and ESG software?

Carbon accounting software focuses on calculating greenhouse gas emissions, usually across Scopes 1, 2 and 3. ESG software covers a wider set of environmental, social and governance metrics, and many platforms include carbon accounting.

How do I choose ESG or carbon software?

Start with the frameworks and regulations you must report against, the emission scopes you need to cover, and the data sources it must connect to. Then compare audit trails, integrations and support.

Do I need ESG consulting services as well as software?

Not always. Software handles ongoing data collection and reporting, while ESG consulting services can help with strategy, materiality and first-time disclosures. See the consultants hub.
