Global Witness - 20th Anniversary logo


The Global Witness Challenge Fund campaign: For every £20 you give to Global Witness, the Open Society Foundations will add another £10.

Global Witness has shown that by applying a forensic focus on evidence, reporting on matters of public interest and proposing solutions, we can achieve great change.

The Open Society Foundations (OSF) has shown its confidence in Global Witness and wants to help build a campaigning organisation that is deep-rooted, long-lasting and even more effective, with a strong infrastructure at its core. They have pledged a grant of approximately £4.5 million to help Global Witness develop and strengthen over the next decade, but only if we match it by raising twice that amount. This is our challenge.

So for every £20 you give to Global Witness they will add another £10.

This is an unprecedented and historic opportunity for us to address the increasingly critical issues the world faces today. You too can join us in debating these issues by joining GW20 or the Campaigners’ Alliance. However, donors of any size will be invited to events and will receive an e-newsletter updating you on our campaigns and investigations.

We need your support to strengthen our fight to change the system by exposing the economic networks behind conflict, corruption and environmental destruction. We can’t continue our investigations and campaigns without your help. We are almost halfway there and with your support, we will reach our goal. All donations of any size are essential and greatly appreciated. Thank you.

Since 1993, Global Witness has been investigating and campaigning to stop elites getting away with looting entire states, from armed factions militarising the natural resource business and for an end to the exploitation of our environment that is destroying lives, habitats and ecosystems.
