The World Benchmarking Alliance's Nature Benchmark measures and ranks the world's most influential companies on their efforts to protect our environment and its biodiversity.

This metric relates to the Indicator: The company reduces the production of air pollutants across the most material parts of its value chain.

Rationale: The production of air pollutants, such as nitrogen oxides and sulphur oxides, through companies' operations and business activities, has adverse effects on the climate, habitats, biodiversity, agriculture, air quality and the health of both animals and humans (GRI, 2021). Moreover, the increase in certain air pollutants can disrupt the provision of ecosystem services, for example nutrient cycling and carbon cycling, but also water supply, on which planetary and human life depends. As such, this indicator measures companies' approach to measuring and reducing harmful air pollutants across the value chain, including beyond national and international regulations.
