Law and policy

Since 2009, there has been renewed international interest in efforts to enhance the weak legal framework intended to protect the environment in relation to armed conflicts (PERAC). The topic has been addressed by the UN’s International Law Commission, and by the International Committee of the Red Cross, and has also been the feature of resolutions at the UN Environment Assembly. Meanwhile, wider questions around environmental security are increasingly on the agenda of the UN Security Council and the war against Ukraine has foregrounded questions of accountability. To learn more about PERAC read our FAQ and our publications.

Briefing: Defining Nature, Peace and Security (NPS)

Narrowly interpreting the relationships between nature and security and prioritising the national security of a few risks repeating past environmental securitisation mistakes, doing little to address the drivers of biodiversity loss. This briefing explores what a more holistic approach to nature, peace and security should encompass, and offers recommendations for its development.

Introducing WISEN: The wartime incidents to environment database

We believe that a more systematic and comprehensive approach to monitoring environmental change in areas affected by conflicts could radically improve how damage is understood, perceived and addressed. Here we introduce our contribution to that vision, our Wartime IncidentS to ENvironment Database, or WISEN.

WISEN: A tool for post-war environmental accountability?

CEOBS’ WISEN tool can help systematically identify and map conflict-linked environmental harm. Lydia Millar explores how this data could be used to improve accountability at local, national and international levels, and the challenges of holding those responsible to account.

1/3 Exciting to see the outcomes from Humanity in War's global initiative for humanitarian law. We participated in the consultations on naval warfare and IHL and peace. 118 states are part of the Initiative, together with the ICRC. https://www.upholdhumanityinwar.org/en #PERAC

2/3 The detailed environmental considerations in the naval warfare outcome are incredibly timely given what we are monitoring in the Black and Azov seas, Persian Gulf and Red Sea.

3/3 As for the the IHL and peace outcome, as an organisation that works to mainstream the environment in humanitarian disarmament, just having environmental risk mitigation and toxic remnants of war situated in an ERW and disarmament context is welcome. https://www.upholdhumanityinwar.org/en#documentation

There's a huge accountability gap when it comes to wartime environmental damage.
