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.

Mining and money: Financial fault lines in the energy transition
This report analyses global financing of transition mineral mining, showing concentrated capital flows, weak financial institution policies, and material environmental and human rights risks. It links bank and investor finance to mining harms across key regions and calls for stronger regulation and safeguards to enable a just energy transition.
Systems-informed stewardship part II: Bringing a systems perspective to stewardship
This article applies a systems lens to stewardship, arguing that fragmented intermediation and entrenched short-term time horizons undermine sustainability outcomes. It calls for recognising these structural barriers as a critical step toward more effective, systems-informed stewardship.
IQAir world air quality series
The World Air Quality Report is an annual research series assessing global air quality using ground-level PM2.5 monitoring data. It provides consistent country, regional and city-level comparisons, supported by transparent methodology and harmonised datasets to inform policy, research and investment analysis.
IPE Green supply chain
The Institute of Public & Environmental Affairs Green Supply Chain Supplier Database tracks environmental compliance of Chinese suppliers. It consolidates government violation records and corporate disclosures to support supply chain due diligence, risk screening, and ESG assessment by investors and companies.
Institute of Public & Environmental Affairs (IPE)

It operates public databases on air, water and supply chain compliance, supporting ESG research, responsible investment, environmental risk analysis, and sustainability decision-making in China.
WESR: Ocean
WESR: Ocean provides high-level insights into ocean-related environmental risks and pressures, including marine ecosystems, pollution and resource use. It supports risk identification and contextual analysis for financial decision-making linked to ocean health, coastal exposure and sustainability considerations.
WESR: Air Visual
The IQAir × UNEP air quality tool aggregates real-time PM2.5 data from thousands of monitors worldwide to show current air pollution exposure and estimates by age group, relative to WHO guidelines. It supports global air quality assessment through an interactive map and hourly updated exposure statistics.
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.
Fashion’s plastic paralysis: How brands resist change and fuel microplastic pollution
The report examines fashion brands’ continued reliance on synthetic fibres, highlighting how voluntary commitments, lobbying, and weak accountability delay fibre reduction and regulation. It links current business models to rising microplastic pollution and concludes that systemic policy and production changes are required.
Assessment of the health impacts and costs associated with indoor nitrogen dioxide exposure related to gas cooking in the European Union and the United Kingdom
The report estimates premature mortality, years of life lost and asthma cases in the EU and UK attributable to indoor nitrogen dioxide from gas cooking. Using modelling of indoor exposures and concentration–response functions, it quantifies associated economic costs and highlights potential health gains from transitioning to cleaner cooking energy
Long-term impact and biological recovery in a deep-sea mining track
The study finds that deep-sea mining disturbance leaves long-lasting physical impacts, with partial biological recovery after 44 years. Some mobile and sessile fauna have re-established, but communities remain altered. Plume effects are limited, yet track disturbance persists, indicating slow ecosystem recovery and informing future management.
Sustainable Finance Roundup November 2025: Transition Turning Points and Rising Accountability
This month’s sustainable-finance roundup highlights faster transition momentum, rising physical risks and a tightening focus on accountability. COP30 reinforced expectations for stronger 2035 targets, while national actions underscored diverging paths toward decarbonisation. Markets continued shifting toward clean energy and resilience, and new science made climate harms more visible. With regulatory scrutiny and litigation increasing, transition credibility and real-economy resilience are becoming core drivers of financial risk and investment decisions.
Transparentem
Transparentem is a non-profit organisation that investigates human-rights and environmental abuses — including child labour, forced labour and pollution — across global supply chains. Through detailed field investigations, supply-chain mapping, and engagement with companies, Transparentem pushes for remediation and systemic industry change to ensure fair working conditions and environmental justice.
Solutions from the One Planet network to curb plastic pollution
The report outlines solutions to curb plastic pollution by improving sustainability information, driving behaviour change, advancing sustainable procurement, and promoting circular economy measures, particularly for plastic packaging. It presents coordinated actions across sectors, including tourism, to reduce plastic use and support systemic, upstream interventions aligned with SDG 12.
The pollution premium
The report “The Pollution Premium” analyses how industrial pollution influences asset pricing. Using U.S. firms’ toxic emission data (1991–2016), it finds that companies with higher emission intensity earn around 4.4% higher annual returns than their low-emission peers, even after accounting for known risk factors. The study introduces environmental policy uncertainty as a new systematic risk, showing that firms more exposed to potential regulatory tightening demand higher expected returns as compensation.
