環保促進會已獲得聯合國環境規劃署(UNEP)的非政府組織認證。本認證為非政府組織提供了數個優勢，包括參與集合了來自全球不同團體的會議、與各國政府代表互動以及影響政策制定的平台。
自2013年起，環保促進會響應UNEP於每年6月5日舉辦的世界環境日，舉辦屬於我們的香港綠色日。
The Green Council has been accredited by the United Nations Environment Programme (UNEP). Accreditation offers several advantages for NGOs including participation in meetings of global groups, interaction with representatives of governments, and a platform to influence policy formulation.
The Green Council echoes with UNEP for World Environment Day to organise the Hong Kong Green Day since 2013.
