Frequently asked questions
B Lab's B Impact Assessment environmental section requires a greenhouse gas emissions inventory covering at minimum Scope 1 and Scope 2 emissions. Increasingly, companies scoring highly also measure and report Scope 3. You'll need documented reduction targets and evidence of year-on-year progress.
B Corp certification is valid for 3 years. At recertification, B Lab reassesses your B Impact Assessment score and requires updated environmental data. Having consistent, platform-based emissions tracking makes recertification significantly easier than rebuilding data from spreadsheets.
No. B Corp certification is voluntary, but it requires a legal commitment — you must amend your articles of association (or equivalent) to formally consider stakeholder impact alongside shareholder returns. The certification itself is administered by the non-profit B Lab.
Climatise provides the complete emissions inventory, reduction tracking, and audit-ready documentation that B Lab's environmental assessment requires. Rather than assembling data manually every 3 years, your emissions data is continuously tracked and ready for assessment at any point.
