Improving air quality monitoring in G20 countries through low-cost sensor-satellite synergies
Air pollution, a critical global environmental problem, severely threatens human health and well-being. To address this crisis, global stocktaking and transparency is crucial. Measurement, reporting, and verification of emissions are vital, necessitating tools like low-cost sensors and satellite systems. The G20 nations, representing a significant portion of the global population and economy, are pivotal to regulating and mitigating air pollution. This policy brief focuses on the challenges that emerging economies face, highlights the role of the G20 in dealing with these challenges, and proposes policy recommendations to enhance monitoring systems. These recommendations involve collaborative research and development, global data-sharing platforms, cooperation with international organisations, and integration with the Lifestyle for Environment (LiFE) mission. The emphasis is on formalising standardised protocols, subnational action plans, and capacity building. By implementing these recommendations, the G20 countries can effectively improve air quality monitoring and contribute to cleaner and healthier environments.
