“I worked with Vishal on several sustainability reporting projects. When we transitioned from one global sustainability software vendor to another, Vishal helped us format the data so I could be incorporated by the new software vendor. When we worked to establish GHG Scope 3 emission estimates, Vishal was key to understanding the emission calculations. It has always been a pleasure to work with Vishal.”

Frequently Asked Questions
Clear answers to help you understand ESG assurance and what to expect.
What's the difference between limited and reasonable assurance?
Limited assurance is a review-level engagement – the assessor checks for plausibility and flags anything that appears materially misstated. Reasonable assurance is audit-level- it involves detailed testing, source document verification, and results in a positive opinion (similar to a financial audit). Most first-time reporters start with limited assurance.
Is ESG assurance mandatory for my company?
It depends on your jurisdiction, size, and listing status. Under CSRD, large EU companies will need limited assurance initially, moving to reasonable assurance over time. California’s SB 253 requires third-party verification of emissions data. Many stock exchanges also require or recommend assurance for listed companies. Our ESG assessment quiz can help you determine what applies to you.
How long does an assurance engagement take?
A typical limited assurance engagement takes 4–8 weeks from kickoff to signed report. Reasonable assurance engagements are more intensive and usually run 8-12 weeks. Timeline depends on the quality of your underlying data and how audit-ready your processes are.
Can you provide assurance on just one part of our ESG report?
Yes. Many clients engage an assessor to verify a specific metric (e.g., Scope 1 & 2 emissions) or a single framework’s disclosures, rather than the full report. We match based on your actual scope.
How do you ensure assessor independence?
All assessors in our network are independent practitioners or firms with no advisory relationship to the companies they assure. We verify independence before every engagement to prevent conflicts of interest- a structural advantage over firms that provide both consulting and assurance.
What qualifications do your assessors have?
Our assessors hold credentials such as CPA/CA, CSAP (Certified Sustainability Assurance Practitioner), Lead Auditor certifications (ISO 14001, ISO 14064), and have delivered assurance engagements under ISAE 3000, AA1000AS, or equivalent standards.
The right assurance expert can save you time and uncertainty.
