        The Collective Business of Going Green: Insights from Singapore's Green 100 National Movement

        Catalyst StageHall 3, Singapore EXPOOpen

        About this session

        For businesses, particularly SMEs in value and supply chains, the case for sustainability is often difficult to translate into action. Costs and complexity are immediate while commercial benefits tend to feel distant and uncertain. · Singapore’s Green 100 movement seeks to change the equation. By converging government agencies, trade associations, financial institutions and the private sector around common pathways, Green 100 makes sustainability simpler to start, scale, and unlock value for businesses that take action. The launch of Green 100 Bronze marks an important shift from recognition to reward. Procurement is singled out as the first major “value unlock”, with Singapore’s public and private sectors working to harmonise recognition of Green 100 in supplier selection and incentivisation. What will it take to translate such recognition into sustained market demand? And how can green procurement be reinforced by green financing, market access, grants, and other economic incentives? Singapore’s 2027 ASEAN chairmanship also raises a wider opportunity. Are there Green 100 learnings that other ASEAN Member States can leverage? Which elements – common pathways, trusted credentials, “queen bee” mobilisation, or value unlocks – can be replicated in other markets? And could these different national approaches become increasingly interoperable over time? This panel brings together leaders from the government, business, procurement and finance sectors to examine the choices, challenges, and next steps for Green 100; and how Singapore’s experience might contribute to broader activation of the ASEAN green economy.
