The Green City Accord is a movement of European mayors committed to making cities cleaner and healthier. It aims to improve the quality of life of all Europeans, and accelerate the implementation of relevant EU environmental laws. By signing the Accord, cities commit to addressing five areas of environmental management: air, water, nature and biodiversity, circular economy and waste, and noise.

The following cities have signed the Accord:

What is the Green City Accord?

Objectives and scope

Cities are critical to meeting the EU's environmental objectives. Many successful actions have already been taken at city level, but further efforts are necessary to tackle rising environmental challenges.

Signatories’ commitments

Signatory cities will commit to tackling the most urgent environmental challenges facing their cities. By joining the Accord, mayors agree to step up their efforts in five key areas by 2030:

  • air: significant improvement in air quality by moving closer to respecting the WHO’s air quality guidelines and ending exceedances of EU air quality standards as soon as possible
  • water: making significant progress in improving the quality of water bodies and the efficiency of water use
  • nature and biodiversity: considerable progress in conserving and enhancing urban biodiversity, including through an increase in the extent and quality of green areas in cities, and by halting the loss of and restoring urban ecosystems
  • circular economy and waste: advance towards the circular economy by securing a significant improvement in the management of household municipal waste, an important reduction in waste generation and landfilling, and a substantial increase in re-use, repair and recycling
  • noise: significantly reducing noise pollution in cities and moving closer to WHO recommended levels

In each of these areas, signatories commit to:

  • establishing baseline levels and setting ambitious targets that go beyond minimum requirements set by EU laws within two years of signing
  • implementing policies and programmes in an integrated manner, to achieve their targets by 2030
  • reporting on implementation and progress every three years

Monitoring framework

Reporting is a core component of the Green City Accord.

Signatory cities are required to report their progress in the five different domains of the Green City Accord. The Monitoring & Reporting system - currently still under development - will reflect progress towards these goals.

To monitor progress towards the Green City Accord’s goals and allow for comparability across cities, a small set of mandatory indicators has been established. All signatories will use these indicators for reporting purposes.

You will find the list of mandatory indicators below.
