A National Movement for Business-Led Climate Action

Green 100 is a national movement launched by Singapore’s Council for a Competitive Climate Transition (C3T) to help businesses accelerate sustainability adoption and unlock green growth opportunities.

Powered by Gprnt’s digital platform, Green 100 enables SMEs to take practical first steps toward sustainability through simplified disclosures at no cost, aligned with TR 149:2026.

Why this Matters

Climate action, made practical

SMEs are key to Singapore’s net-zero transition

They make up 99% of businesses and contribute about 40% of emissions. Yet many SMEs have not started their sustainability journey because it feels complex, costly and difficult to navigate.

This is a shared challenge

SMEs that delay action risk losing customers and missing opportunities to reduce costs and access green financing. At the same time, enterprises cannot accurately measure supply chain emissions or meet stakeholder and regulatory expectations without engaging their SME suppliers.

An ecosystem approach is essential

Government, enterprises, SMEs and solution providers must work together to align requirements, build capabilities and make sustainability simple and affordable to adopt. Green 100 provides the platform to do this at scale.

Led by Singapore’s  
Council for a Competitive Climate Transition (C3T)

C3T is a public-private partnership platform launched in Singapore by the National Climate Change Secretariat (NCCS) and the Singapore Business Federation (SBF), to help strengthen businesses’ climate resilience and competitiveness.

6 April 2026 - The establishment of C3T was announced by Ms Grace Fu, Minister for Sustainability and the Environment and Minister-in-charge of Trade Relations, at SBF’s Post-COP30 Dialogue.

What is TR 149

Built on Singapore's
National Sustainability Standard (TR 149)

Green 100 is anchored on the TR framework, helping SMEs take practical first steps in sustainability through simplified disclosures at no cost.

For many SMEs, navigating evolving sustainability expectations can be challenging due to limited resources, expertise, and fragmented requirements. TR 149 directly addresses these challenges by offering a clear framework for businesses to assess their sustainability maturity level and measure their progress over time.

Through Green 100, SMEs are introduced to the TR 149 Essential level requirements—an accessible starting point designed to help businesses begin their sustainability journey with confidence while paving the way toward higher levels of sustainability readiness over time.

By simplifying disclosures and lowering costs, it helps SMEs get past the first hurdle. By tying the Green 100 badge to procurement incentives and financing opportunities, it makes sustainability not just viable, but valuable for business.

Green 100 supports the C3T’s focus on helping businesses navigate their green transition by making it simpler and faster for SMEs to take the first meaningful step on their sustainability journey. By using TR 149:2026 as a common framework and working through large Queen Bee enterprises, we can scale impact quickly across entire value chains, while keeping costs low and requirements practical for smaller firms.

I encourage more listed companies to step forward, seize the growing array of opportunities available through ecosystem enablers such as SGX, C3T, and Gprnt, and turn climate action into sustainable and practical business outcomes.

SMEs form the building blocks of national economies, yet efforts to green them at scale have met with limited success worldwide. The Green 100 leverages Singapore’s strengths – robust public-private leadership and coordination, a new national standard, and the world’s first digital utility for sustainability reporting – to partner Queen Bees in significantly lowering the barriers for their SMEs to get started, and in doing so access granular and verifiable on their supply chains. And as the Green 100 moves to progressively incorporate real market demand in the form of procurement, financing, and green growth opportunities, we start to make sustainability not just viable, but valuable.
