We believe the only way to scale credible climate and ESG action is through intelligent data infrastructure — powered by technology, made affordable through automation, and grounded in real-world operations.
Where We Create Impact
Lead with Rio
Financial institutions face growing pressure from investors, regulators, and clients to improve ESG transparency and integrate sustainability across their portfolios.
Rio supports banks, asset managers, and private equity firms by providing audit-grade sustainability data, automated reporting tools, and advanced ESG risk insights.
Use Rio to monitor and benchmark sustainability performance across your entire investment portfolio, generate accurate and defensible emissions data, and automate workflows to meet internal and external disclosure demands.
Whether you're tracking financed emissions, managing ESG due diligence, or enhancing stewardship efforts, Rio gives financial leaders the tools to report confidently and act strategically.
"We believe that to effectively address sustainability in finance we need to bring finance, technology, and sustainability specialisms together. That is how we have constructed our approach to ESG at Coller Capital and that is how Rio.ai has constructed their business also."
Partner, Head of ESG and Sustainability, Coller Capital
Build with Rio
In infrastructure, winning contracts and delivering projects increasingly depends on how well you meet sustainability requirements. From planning to delivery, Rio gives developers, constructors, and operators the visibility, control, and credibility needed to meet ESG expectations across the value chain.
Use Rio to gather and assess real-time data on emissions, waste, water use, biodiversity, and social impact across suppliers, subcontractors, and materials. Align projects with international benchmarks such as PAS 2080 and sectoral net-zero goals, while uncovering opportunities to reduce costs, minimise risks, and deliver long-term value. From rail to real estate, Rio helps infrastructure firms embed sustainability at every level.
“Carbon reduction is the single most pressing challenge of this century and investors need the tools to understand their contribution to the problems and solutions. Greenlight recognise the absolute importance of carbon reduction (for our own/portfolio company's) footprint. We have found Rio’s support in managing and understanding our data invaluable. If investors are to make meaningful changes, having the tools and expertise of a partner such as Rio is a must.“
Managing Director, Greenlight Group
