Legislators, courts, investors and civil society are all converging around the idea that the most severe environmental harms should attract the highest level of responsibility - including criminal liability - for decision-makers.
The Independent Expert Panel for the Legal Definition of Ecocide, convened by the Stop Ecocide Foundation, proposed in 2021 a consensus definition of “ecocide” that has rapidly become a reference point for lawmakers, academics and practitioners worldwide.
Ecocide law sits alongside developments such as:
- growing climate and biodiversity litigation against corporates and directors
- mandatory human rights and environmental due diligence regimes, and
- recognition of the right to a clean, healthy and sustainable environment in many jurisdictions.
The rapidly growing momentum behind international, regional and national ecocide laws means that helping clients understand and anticipate ecocide-related developments is part of robust horizon scanning, risk management and governance, placing ecocide law within this bigger picture as a logical next step in environmental accountability.
In-house counsel and private practice lawyers supporting corporate, finance and insurance clients are uniquely placed to advise on ecocide law in a constructive and commercially relevant way, helping to embed ecocide law in a framework for responsible business strategy.
The good news for clients
Ecocide law is targeted at the worst harms
The emerging standard focuses on severe damage that is widespread or long-term, and on conduct that is unlawful or wanton – a far higher bar than ordinary regulatory non-compliance. It is not designed to criminalise every environmental incident, but to address the most egregious cases of ecological destruction.
Responsible businesses have most to gain
- Clear criminal boundaries sharpen the line between good and bad practice.
- Companies already investing in high environmental standards benefit from a more level playing field as competitors cutting corners face meaningful consequences.
- Strong internal governance now can significantly reduce future liability and reputational risk.
Early preparation is cheaper than late reaction
- Mapping operations against emerging ecocide-type thresholds helps identify “red flag” activities before they become stranded assets or litigation hotspots.
- Integrating ecocide considerations into due diligence, project finance documentation, insurance and M&A processes can be incremental, building on existing ESG and risk frameworks.
