Sustainability at ACG

Human activity undeniably impacts nature and climate with devastating consequences on the planet and all its inhabitants. As a leading educational institution, Τhe American College of Greece (ACG) recognizes the environmental, economic, and social benefits of resource efficiency and commits to educate, inspire and empower its students, as well as faculty, staff, parents, alumni, trustees, and business partners, to develop a sustainability culture on campus, collaborating with the local community in promoting sustainability best practices.

Following US best practices and as also reflected in its President’s 2025 vision, The American College of Greece is gradually developing an ever-growing number of sustainability best practices. ACG is committed to systematically addressing issues from sustainability focus in academic programs and research and reducing its carbon footprint while improving its energy efficiency, to enhancing its social impact and increasing transparency and accountability in its daily operations.

For all its relevant activity, ACG has been awarded the STARS Gold Rating, in recognition of its best practices in five categories: Academics, Engagement, Operations, Planning & Administration and Innovation & Leadership. ACG is the only academic institution in Greece to have received a distinction by the US AASHE – an internationally acclaimed association. Through its membership in the UN Global Compact, the UN Academic Impact and the UN Sustainable Development Solutions Network (SDSN), ACG has committed to always operate in support of the UN SDGs – and most importantly, Goal No 4: Quality Education.

At ACG we place a strong emphasis on providing our students – the leaders of tomorrow – with the knowledge, values, and experiences needed to navigate this everchanging environment while acting as engaged and responsible citizens and professionals, in order to help create a more socially, economically and environmentally sustainable world.
