Cars contribute to air pollution and carbon emissions, but switching to public transport, cycling, or walking can help reduce your environmental impact. Singapore’s efficient MRT and bus network makes it easy to get around sustainably. For shorter trips, consider using bike-sharing services, or simply walking if your destination is within 2km. You can also plan car-free days, where you rely entirely on public transport or active mobility options for a day each week. Small changes in your daily commute can add up to a significant reduction in emissions and a healthier environment.
