<s>[INST] The next text is a question of a member of the European parliament:"Around one hundred cities across the European Union have signed up to the ‘Mayors Adapt’ initiative, under which their city councils commit to developing a comprehensive climate adaptation strategy or integrating this aspect into existing plans so as to address the consequences of climate change.   This is one of the action plans set up by theEU to deal with this challenge, with emphasis on the importance of cities, which are becoming ever more populous and which represent approximately 70% of the world’s demand for energy and of global greenhouse gas emissions.  However, the number of cities that have assumed this commitment is still low.  What measures will the Commission adopt to publicise this initiative and get more cities to sign up to it?  What other instruments will be employed to achieve greater commitment from the conurbations where most of the population is concentrated with a view to addressing the challenges posed by climate change for the European Union?"
