Generational Sustainability Behaviors: Gen Z Singaporeans Talk Green but Baby Boomers More Likely to Act: NUS SGFIN Study (Feb 16, 2026)

Unpacking the Singlife-SGFIN Sustainable Future Index 2026

The Singlife-SGFIN Sustainable Future Index (SFI) 2026, a collaborative research effort between leading insurer Singlife and the Sustainable and Green Finance Institute (SGFIN) at the National University of Singapore (NUS), sheds light on generational sustainability behaviors in Singapore. Released on February 16, 2026, this study surveys 1,500 Singaporeans and Permanent Residents to explore how awareness translates—or fails to translate—into action across daily habits, spending, financial decisions, and community engagement.

At its core, the index employs the Awareness-Knowledge-Ownership-Action (AKOA) framework to dissect 25 specific sustainability-related actions grouped into four pillars: responsible investing, acting on climate change, inclusive and sustainable solutions, and society and culture. This rigorous approach reveals a striking paradox: while Generation Z (born 1997-2012) boasts the highest awareness, Baby Boomers (born 1946-1964) demonstrate the most consistent green actions.

Generational Breakdown of Sustainability Awareness

Singapore's youngest cohort, Gen Z (survey sample n=260), reports 60% fully or mostly aware of environmental sustainability concepts, outpacing Millennials (42%, n=581), Gen X (40%, n=549), and Baby Boomers (31%, n=111). Awareness of social sustainability follows suit at 43% for Gen Z versus 35% Millennials, 27% Gen X, and 29% Boomers. Economic sustainability awareness is more even, with Gen Z at 34% and Boomers at 32%.

This heightened awareness among youth stems from greater exposure to climate discourse, social media, and global events like pandemics, positioning Gen Z as vocal advocates. However, the study underscores that knowledge alone does not suffice; it must couple with ownership—the personal belief in one's responsibility to effect change.

The Action Gap: Boomers Lead in Everyday Green Habits

Despite superior awareness, Gen Z trails in action adoption. For reusable bags and containers, 95% of Boomers and 90% of Gen X use them regularly, compared to 73% of Gen Z. Waste recycling sees 78-81% among older groups versus 52% Gen Z. Public transport, walking, or cycling: 77% Boomers, 72% Gen X, 62% Millennials, 49% Gen Z. Energy-efficient appliances: 81% Boomers, 70% Gen X, 72% Millennials, 56% Gen Z.

Low-barrier actions like eating less red meat (96% overall) and consuming clean electricity (94%) enjoy near-universal intent, highlighting feasibility when cost is minimal.

Ownership: The Key Driver Bridging Say and Do

Ownership emerges as pivotal: 83% across generations feel personally responsible for reducing environmental harm. Yet, translation to behavior varies. Boomers exhibit strongest alignment, with 81% prioritizing support for vulnerable groups—essential for sustainable society. Gen Z shines in community ownership, with 74% intending to volunteer for seniors/disabled care and 64% for sustainability events.

Associate Professor Zhang Weina, SGFIN Deputy Director, emphasizes the AKOA framework's role in pinpointing gaps: "This year's survey findings enable us to identify specific gaps to influence Singaporeans across different age and income groups to adopt sustainable lifestyles."

Barriers Holding Back Sustainable Choices

Financial trade-offs loom large: 65% prefer sustainable companies, but only 38% will pay premiums. Gen Z, often price-sensitive, favors affordable fast fashion despite eco-preferences. Convenience and doubt in individual impact further widen the say-do chasm, particularly among youth questioning systemic efficacy.

• High cost of organic food, EVs, eco-labels deters uptake.
• Urban density limits options like home composting.
• Trend-driven consumption overrides intentions.

Gen Z Excels in Social Sustainability

While lagging environmentally, Gen Z leads socially: 66% plan community health events, 74% volunteer support. Actions like sharing sustainability discussions or donating thrive here, reflecting digital natives' community focus.

This aligns with global trends where Gen Z prioritizes equity alongside ecology, per studies like Deloitte's Gen Z surveys.

Singapore's National Green Push and Individual Roles

The Singapore Green Plan 2030 anchors national efforts with five pillars: City in Nature, Energy Reset, Sustainable Living, Green Economy, Resilient Future. 2026 targets include 20% waste-to-landfill reduction per capita, quadrupling solar deployment, and cleaner vehicles. Individual behaviors amplify these: reusable habits support waste goals, efficient appliances aid energy reset.

Government incentives like EV rebates bridge cost gaps, yet the study calls for tailored nudges per generation.
