Sustainability at ACG

Today, the fact that human activity impacts nature and climate in a harmful manner with direct consequences on the environment, society and the economy is an undisputed scientific reality. It is vital for today’s students -the leaders of tomorrow- to understand how sustainable development can reverse environmental degradation and the climate change spiral and mitigate their tremendous social and financial side effects.

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. In this context, the ACG Center of Excellence for Sustainability (CES), officially established in 2011, is a collaborative initiative, operating under the Office of Public Affairs, which leads all sustainability-related activity, bringing together education, research and operations to advance sustainability on campus.

Our Vision

Our Mission

To raise awareness and engagement of ACG students with sustainability best practices and empower them to become knowledgeable, sensitized and responsible citizens of the world.
