OECD COP28 Virtual Pavilion

Supporting climate- and health-friendly urban communities and economies

Nov 28, 2023 | 3:00 PM - 4:30 PM


Currently, half of the world population resides in cities, with this figure projected to rise until 2050. The increasing trend of migration to cities is often attributed to an “agglomeration of benefits” that cities offer such as access to employment opportunities, education, and healthcare. But the health and well-being of residents in cities is negatively affected by a lack of opportunities for physical activity, exposure to high levels of outdoor air pollution, and rising temperatures more acutely felt cities. Cities are also a key contributor to global warming, consuming two-thirds of the world’s energy and producing over 70% of all CO₂ emissions. Because of widespread car ownership and car-centric urban design, people in cities frequently drive for short trips that could be walked or cycled. Overall demand for transport activity (for both passenger and freight) is growing rapidly and is predicted to roughly double between 2005 and 2050. This session will discuss projects that are being undertaken at city level to reduce both air pollution and GHG emissions, focusing on best practice policies and highlighting the importance of partnerships between cities and other stakeholders to ensure these practices are more widely promoted and taken up.
