According to the State of Global Air Report 2025, 7.9 million premature deaths annually can be linked to air pollution. UNEP highlighted in its 2024 Food Waste Index Report that in 2022 alone, the world wasted more than 1 billion tonnes of food in the retail, food service, and household sectors combined.
