Frequently Asked Questions

Do I need all these tools?

No. Start with 2–3 tools relevant to your priority areas. Most organisations use GHG Protocol (environment), B Impact Assessment or GRI (social), and a governance scorecard.

Which tools do African banks accept for green financing?

Most accept GHG Protocol calculations and recognised certifications (B Corp, FSC, Fairtrade). Check with your specific bank

Are these suitable for small African businesses?

Yes. We've prioritised free tools that scale to businesses of all sizes. GHG Protocol, B Impact Assessment, and GRI all work for SMEs.

What if i dont find all the data?

Start with what you have. Most tools allow partial completion. Use estimated data initially and refine over time.

How long do assessments take?

Initial assessments: 2–10 hours depending on complexity and data availability. Annual updates: 2–4 hours once systems are in place.

Can I use multiple tools simultaneously?

Yes, and it's recommended. GHG Protocol for emissions, B Impact Assessment for social metrics, and GRI for comprehensive reporting complement each other.
