Carpooling and Hybrid Work Could Slash G20 Carbon Emissions by 20%

A new report finds that combining carpooling, increased bus usage, and hybrid work arrangements could reduce G20 carbon emissions by up to 20%. The study projects that raising average car occupancy by 50% above current levels could deliver annual savings of approximately 237 million tonnes of CO2 by 2050. These behavioral and mobility shifts are seen as practical, low-cost interventions that complement broader decarbonization strategies. The findings highlight the significant emissions impact of everyday commuting choices across the world's largest economies.
