For 14 years, the Climate Change Working Group (CCWG), founded in 2008, has been a driving force in climate action. The CCWG brings together international and Vietnamese non-governmental organisations, development agencies, institutions, professionals, and other interested parties to exchange ideas and discuss lessons learned and good practices. The CCWG has grown to be a powerful coalition of over a hundred organisations, with a combined budget of approximately USD invested in climate change actions between 2018 and 2020. In addition, the CCWG maintains an approximately 1,300-person mailing list.
