About Us
Founded on practical sustainability expertise and a belief that impact happens through people
At Sustainao, we believe sustainability is more than a responsibility—it is a strategic advantage.
We see sustainability as a continuous journey, driven by people through the decisions they make every day. That’s why we believe the role of sustainability consultancy isn’t just to produce strategies and reports— it's to empower teams, build capabilities, and drive meaningful progress across the organisation.
As your fractional sustainability team, we help turn sustainability from a complex challenge into a practical driver of business value.
Whether you're just beginning your sustainability journey or looking to strengthen and scale existing initiatives, we provide the expertise, structure, and support needed to embed sustainability into everyday operations and decision-making.
Our approach is built around The Sustainao Method, our structured five-pillar framework covering Awareness, Strategy, Deployment, Reporting, and Recognition. Through our Start, Shape, and Sustain offerings, we apply this framework at the right depth and pace for your organisation's needs and maturity.
We work with organisations of all sizes—from SMEs to multinational companies—across a wide range of sectors. Our support spans sustainability strategy, governance, training, implementation, reporting, ESG ratings, and specialised topics such as climate change, sustainable procurement, labour and human rights, and diversity, equity and inclusion (DEI).
Most of our client relationships are long-term partnerships, allowing us to operate as an extension of their teams and provide continuous support as their sustainability needs evolve.
We have helped organisations strengthen their sustainability performance, achieve recognised ESG ratings such as EcoVadis, CDP, and GRESB, and earn awards including the Singapore Apex Corporate Sustainability Awards and Company of Good.
More than advisors, we become part of your team—providing clarity, building trust, and delivering actionable insights that make sustainability your business advantage.
We don’t just offer advice—we walk the sustainability path with you.
