UNESCO's Environmental Commitment and Policy

"I am strongly committed to making environmental considerations central to all of UNESCO’s operations, facilities and activities, drawing on our expertise from many successful UNESCO programmes in the area of environmental sustainability and climate action. We need to bring about sustainability from within." Audrey Azoulay - UNESCO Director-General

UNESCO's environmental sustainability management

Environmental protection and climate action are a core part of UNESCO’s mission – these considerations are embedded within both its programmes in support of Member States as well as its own operational conduct. By integrating ambitious environmental criteria and targets into UNESCO’s management strategies, administrative policies and operations, the Organization’s environmental footprint could be substantially reduced since 2019. 

By setting up its Environmental Management System (EMS) in line with the ISO 14001 standard and rolling it our across the UNESCO Field network, great steps forward have been made in improving the environmental performance of UNESCO

Key objectives of UNESCO’s Environmental Sustainability and Management Policy:

  • Fully account for the externalities imposed by UNESCO’s own operations and facilities.
  • Minimize any possible negative impact on the environment through targeted measures and continuous improvement, and contribute positively to protecting the environment and communities in which the Organization operates.
  • To fully compensate for UNESCO’s unavoidable environmental footprint by systematically measuring and reducing greenhouse gas emissions, in line with the goals of the Paris Agreement, and offsetting all emissions which remain.

Key highlights and achievements

UNESCO is implementing a global Environmental Management System (EMS), in line with the UN’s 2020-2030 Sustainability Strategy. This has driven the development of a holistic framework to plan and conduct activities, aiming to minimize the negative impacts on the natural environment and fostering continuous improvement. While this agenda encompasses both increasing efficiency and integrating ambitious operational measures, it has embedded environmental sustainability across UNESCO’s global operations.

UNESCO
December 2021

Face-to-face meetings have a considerable impact on the environment, caused mainly by the associated travel, facilities, catering and accommodation and support material. While shifting meetings online or hybrid is the best way to reduce their environmental impact, this is not always possible. Therefore, 91Âé¶¹¹ú²ú¾«Æ·×ÔÅÄ developed Guidelines for Green Meetings to help minimize the environmental impact of meetings and events organized by UNESCO.
