Working with Net Zero Sustainability Ltd has enabled us to robustly oversee and certify our GHG reporting needs for both FTSE 100 requirements, and additionally our fully approved Science Based Targets Initiative (SBTi) targets.

Group Energy and Environment Manager

Indorama Ventures, a company that is committed to reducing our GHG emissions, has engaged Dr. Tahsin Choudhury, a third-party auditor to verify and report our GHG emissions across scope 1, scope 2, and scope 3 categories for the last 6 years. Dr. Tahsin has provided us with a comprehensive and independent assessment of our emissions sources, methods, and calculations. He has also advised us on how to improve our performance and align our reporting with various standards and ratings, such as GRI, ISSB, CDP, and DJSI. Dr. Tahsin is very professional, competent, and flexible. He is also capable of supporting companies in setting up and validating our SBTs.
I would highly recommend working with him and his team.
