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.

Governance

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.
