Controversies

In october of 2025 the Global Center on Adaptation was the subject of a major controversy involving fabricated and exaggerated results. Over a period of six months, NOS investigated the Global Center on Adaptation, speaking with more than seventy individuals involved both domestically and internationally. In addition, hundreds of documents were reviewed, finding and concluding that the GCA was taking credit for other people’s work. Not only did the GCA exaggerate its own contributions to projects, with GCA claiming to have initiated $25 billion in investments, which supposedly benefited more than 82.5 million people and created jobs for 900,000 people — all while operating on an annual budget of just €23 million, but it also claimed to be part of at least 18 World Bank projects — which it was not.The NOS spoke with more than twenty former employees of the GCA, revealing that CEO Patrick Verkooijen personally exerted pressure to exaggerate results in order to secure donor funding. Verkooijen also claimed that Norway and Denmark would be increasing their support for the GCA in the near future, despite both countries denying this.
