This article is designed to help you understand the work before you start. It uses the service scope, document checklist and common questions maintained by LEGAL CENTRE; final requirements remain subject to the relevant authority and your facts.
Why this matters to a new or growing CA practice
ICAI’s Sustainability Reporting Standards Board issued an exposure draft of SSA-5000 in May 2026.
Even before final implementation, the draft is a useful signal for new CAs: sustainability assurance is moving toward structured engagement acceptance, evidence, quality and reporting disciplines similar in seriousness to established assurance work.
What to understand
- Read the exposure draft with a focus on engagement acceptance, materiality, evidence and reporting.
- Compare financial-audit evidence habits with sustainability-data evidence.
- Learn how greenhouse-gas, social and governance metrics are generated inside businesses.
- Track the final standard before accepting work that depends on it.
What to do in practice
- Create a sustainability learning file.
- Map common BRSR metrics to underlying source systems.
- Practice evidence testing on non-financial data.
- Record changes between exposure draft and final standard when issued.
Working-paper checklist
- Create a dated working-paper note stating the objective and scope.
- Keep the primary-source document or link used for the conclusion.
- Record client/practice impact, owner and next action.
- Retain reviewer sign-off for material professional judgement.
Common mistakes to avoid
- Treating an exposure draft as final law.
- Ignoring the need for subject-matter competence.
- Assuming sustainability data has the same controls as financial ledgers.
Current-source note

Answers before you start.
Is this article a substitute for the current ICAI or regulator material?+
No. Use it as a practice orientation and working-paper checklist. Verify the current primary source for the engagement date and facts.
What should a newly qualified CA document first?+
Document the objective, scope, primary source, key facts, professional judgement, reviewer conclusion and next action.
How should a small CA firm use this guide?+
Convert the relevant points into a repeatable checklist or standard operating procedure, then adapt it to the client and engagement.
How do I keep this topic current?+
Maintain an official-update log and record the effective date and impact whenever ICAI or the regulator issues a new announcement, circular, standard or portal change.
Rules, forms, portal processes, statutory fees, timelines and eligibility can change. Confirm the current requirement for your specific case before relying on a filing or compliance step. LEGAL CENTRE is a private service-assistance platform and is not a government authority.
