From environmental modelling to independent assurance — we don’t just report ESG, we engineer, verify, and operationalise it. Across 14 jurisdictions.
Your regulatory obligations are multiplying. We work across all of them.
Sustainability — using resources in a way that allows them to renew and continue without external input.
Resilience — the ability to recover from disruption by anticipating risks and building systems that adapt.
Resilient Sustainance — engineering both together so environmental performance is durable, verifiable, and built to last.
We are an ESG, sustainability, and climate advisory group — engineers, scientists, and field experts who don’t just plan, we execute. Across 5 entities in 4 countries, we engineer the environmental performance that survives the audit.
From air dispersion modelling and EIA to CSRD reporting, carbon verification, and AA1000 assurance — we cover the full lifecycle from site assessment to independent verification. And we build the digital tools so organisations can operate independently after we leave.
To accelerate the transition to a climate-resilient, equitable, and sustainable future — by making environmental performance a strategic advantage for every organisation.
Environmental engineering, air/noise/water modelling, EIA, and site assessments — the technical foundation that makes compliance real.
ESG strategy, climate risk, multi-framework reporting, carbon management, and CSR — across 20+ frameworks and 14+ jurisdictions.
Independent assurance under AA1000, ISAE 3000, and ISSA 5000. GHG verification through GAB-accredited GSustain. ISEP accredited.
6 platforms and 50+ tools — so organisations can operate independently after we leave the room.
Six integrated service lines spanning environmental engineering, specialist modelling, ESG advisory, corporate responsibility, water & waste, and regulatory compliance.
Materiality, strategy, climate risk, net-zero roadmaps, multi-framework reporting (GRI, CSRD, BRSR, ISSB), assurance preparation, ratings advisory, and green finance.

The Hinduja Foundation appreciates the work carried out by RSustain in the Engineering Audit of our Lake Rejuvenation and Water Initiatives across Tamil Nadu, Andhra Pradesh, Maharashtra, Karnataka, and Chhattisgarh. The RSustain team completed field assessments, reviewed technical and impact-related data, and submitted recommendations that have supported our programme improvements.
RSustain helped us build a complete CSRD-ready data architecture in 10 weeks. When our auditors arrived, every evidence trail and calculation note was exactly where it needed to be. No surprises.
We were overwhelmed by CBAM requirements. RSustain ran a supplier engagement programme, built our embedded emissions calculations, and had us filing accurate quarterly reports within 6 weeks.
The RSustain Academy FCEM course gave our team a shared language and rigorous methodology. Three months later, we passed our first ISEP-aligned environmental audit with zero non-conformances.
The course enhanced my understanding of key fundamentals and decision-making tools that I can apply professionally. A solid foundation for environmental management practice.
I developed a deep understanding of sustainable buildings, UK legislation, and report writing including EIA, CEMPs, and SEA.
I gained strong knowledge in critical concepts like life-cycle thinking, EIA, and cost-benefit analysis. The course was well-balanced.
Environmental & Sustainability services for Doha Metro projects, provided by the RSustain team through Qatar Design Consortium, were good quality and on time. I would recommend other contractors to avail of their services, which are economical and at the same time, meet the requirements of the project.
The RSustain team worked with us on a large EPC-type project in Doha handling Environmental Management. They had to cope with extended environmental requirements of local regulation and our own hesitation to spend major efforts on what we considered sideline environmental issues. They solved the given tasks fast and successfully. Real professionals.
Having worked with the RSustain team, I have found them willing to go the extra mile and make that extra effort, often in the face of adverse and pressing circumstances. Their knowledge of environmental issues is second to none and they always delivered when requested, even in the face of tight deadlines. Pleasant, very personable and consummate professionals.
The RSustain team managed the Lagoons Project involving multiple players, sometimes with conflicting interests. Yet, they managed to weave their way through and were able to efficiently and productively provide the client with the requested services. Their work was well appreciated.
It was a real pleasure working with the RSustain team. They are competent, knowledgeable and experienced in environmental issues and concerns. Helpful and easy to get along with, whilst continually delivering good quality results consistently meeting deadlines and targets. Solid and reliable.
If you need someone to be proactive and up to date with all Environmental and Sustainability laws and protocols — an all-round Environmental specialist — then RSustain is one of your top choices to go to.
We appreciate the timely completion of the CSR Programme Fund Audit covering compliance and eligibility review, governance and documentation assessment, financial systems verification, and submission of observations and recommendations. The scope was delivered on schedule and to standard.
