We work across financial services, energy, manufacturing, real estate, technology, and the public sector. Our frameworks are sector-agnostic but our delivery is always sector-specific, drawing on deep understanding of materiality drivers in each industry.
RSustain operates across 14+ jurisdictions with direct presence in the UK, India, Qatar, and the USA. We provide advisory services covering EU (CSRD/ESRS), UK (SDR/SECR), India (BRSR/SEBI), GCC, and APAC regulatory frameworks.
Yes. Independent assurance under AA1000 (Type 1 and Type 2) and ISAE 3000 is delivered through GSustain QFZ LLC, which holds ISEP accreditation. The advisory practices (UK, India) maintain independence from assurance delivery. RSustain USA also provides verification services.
This varies significantly by scope. A CSRD readiness assessment might take 4–6 weeks, while a full ESG strategy and implementation programme typically runs 6–12 months. We always begin with a scoping conversation to understand your timeline and constraints.
