International commitments

Barcelona has been aware of this problem for many years and has worked both on adopting international and local commitments and on approving various measures and plans aimed at mitigating the effects of climate change or adapting to it. The most relevant international commitments are detailed below:

  • The Covenant of Mayors for Sustainable Energy, signed in 2008 represents the main objective in terms of mitigation and aims for a minimum of 20% reduction in greenhouse gas emissions by the year 2020.

  • The Making Cities Resilient campaign and its “10 essentials” (2013)

  • The European Union’s Covenant of Mayors Initiative on Climate Change Adaptation (Mayors Adapt), signed in 2014, represents the main commitment in terms of adapting cities to climate change and established the preparation of a climate change adaptation plan.

  • The “Compact of Mayors”, signed in 2015, is a global agreement, beyond the European Union, which is the reaffirmation of the city in terms of its main commitments, both to mitigation and adaptation, included in the Covenant of Mayors and in the Covenant of Mayors for Adaptation.

  • The Declaration and Agreement of the Network of Cities and People towards Sustainability in support of the Lima communique, signed in 2015, with no specific quantitative targets, represents a strategic positioning of all the members of the Network of Cities and People towards Sustainability, including Barcelona.

  • The Covenant of Mayors for Climate & Energy, signed in 2017, in which the above European climate change mitigation and adaptation initiatives are combined. This Covenant was born with the aim of blending mitigation through adaptation, with the objective of reducing greenhouse gas emissions by 40% by 2030 and increasing the resilience of cities.

  • Paris statement. The 21st United Nations Climate Change Conference (COP21), which was held in Paris, from 30 November to 12 December 2015. 195 cities assumed a leading role and it was under their Paris Declaration that they agreed to work towards and exceed the goals established in the Paris Agreement to keep global warming below 2 °C; producing participatory resilience strategies and action plans for adapting cities to climate risks (2020) and making the transition to 100% renewable energies and an 80% reduction in GHGs by 2050. Barcelona joined this initiative by presenting the Barcelona Climate Commitment.
