Pollution
Pollution is the contamination of the environment by chemical, physical, or biological agents that alter its natural characteristics. Long-term pollution exposure can cause severe health and environmental impacts. Sustainability efforts focus on reducing pollution by minimising waste, promoting recycling, and converting waste into useful materials. Investors can engage with companies to encourage pollution reduction initiatives, adoption of cleaner technologies, and transparent reporting on environmental impacts.

The thematic assessment report on the interlinkages among biodiversity, water, food and health
IPBES assesses links between biodiversity, water, food, health and climate, finding siloed decisions worsen trade-offs. It identifies integrated governance, sustainable consumption, ecosystem restoration and finance reform as response options to support more just and sustainable outcomes.
The unseen costs of blue skies: Pollutant substitution and biodiversity loss
China’s PM₂.₅-targeted regulation reduced particulates but increased O₃ via pollutant substitution driven by incentive distortions. Resulting ozone rises increased mortality and reduced biodiversity, offsetting ~24% of policy benefits. Findings highlight welfare losses from narrow performance metrics and the need for multi-pollutant regulation.
The case for pricing pollution: Reducing emissions, strengthening the economy, and delivering a fair share for Australians
The report argues Australia should introduce a Polluter Pays Levy and Fair Share Levy to cut emissions, raise revenue, compensate households, improve productivity, and secure fairer returns from fossil fuel resources.

Historical redlining and cumulative environmental impacts across the United States
This study analyses 202 US cities, linking historic redlining to higher present-day cumulative environmental burdens. Using EJScreen data and modelling, it finds redlined neighbourhoods face significantly greater combined pollution exposures, particularly from traffic, hazardous waste and wastewater sites, with strongest disparities in western regions.
