The City of Brussels has signed the Covenant of Mayors for climate and energy, and has drawn up its climate action plan. This new commitment follows on from the 'Agenda 21' launched in 2008. As such, the climate plan will supplement what has already been achieved in terms of mobility, sustainable urbanisation, green spaces, energy, etc. This tool is essential for planning the efforts to reduce greenhouse gas emissions, and adapt the territory to climate change. It was drafted in 2 stages: firstly an assessment and then the climate plan itself.


In the first instance, the City had an assessment (FR) carried out. It includes the following:

  • a calculation of the greenhouse gas emissions produced within the territory, also referred to as a mitigation diagnosis,
  • a vulnerability study of the territory regarding the effects of climate change, or an adaptation diagnosis.

Mitigation diagnosis

The results in terms of emissions of greenhouse gases are encouraging :

  • 16% fewer CO2 emissions produced by the City administration since 2008.
  • 18% fewer CO2 emissions produced by the activities linked to the City's territory.

Adaptation diagnosis

Thanks to the adaptation diagnosis, two major risks that could impact the City of Brussels were highlighted:

  • more intense rainfall which could increase the risk of flooding,
  • the occurrence of the urban heat island effect, corresponding to a very localised rise in temperatures. The risk of these phenomena is exacerbated in particular in streets without greenery.


Participatory process

The City of Brussels wanted to put the public at the heart of the action, by consulting Brussels residents, who submitted more than 300 ideas. These formed the basis of the climate plan, which was supplemented by the expertise of staff members.

EU objectives

With this plan, the City of Brussels targets the European objectives which it has undertaken to achieve by 2030 by signing the Covenant of Mayors for climate and energy:

  • reduce emissions of greenhouse gases by at least 40% (compared to 1990)
  • bring the proportion of renewable energies to the minimum threshold of 27%
  • improve energy efficiency by at least 27%

In addition, it wishes to adapt the territory to the effects of climate change.
