Paris is a city in transition: from dependence on fossil fuels to renewable energy; from streets dominated by cars to routes adapted to cyclists and pedestrians; from being part of the cause of climate change to offering part of the solution.  There’s a long way to go, to meet the targets in the city’s climate and energy plan, but there are lots of positive projects underway.

One symbolic, but also practical, aspect of the city’s environmental commitment is the installation of green walls and green roofs; the transition from grey to green.There are over a hundred green walls of various sizes already in place in the city and another 41 due to be installed soon.  A panel of greenery doesn’t instantly make a building energy efficient but green walls and roofs do make a positive contribution to insulation and to summer cooling.

Other, less eye-catching developments are in progress to reduce the energy use of the city’s building stock and to generate renewable energy.  These solar panels are part of a temporary exhibition outside the Hôtel de Ville.  In normal use, installed according to the city’s guidelines, they would be inconspicuous or out of sight on a roof or facade.

Hidden within the structure of a building, new systems in development, in collaboration with utility companies, will reclaim heat from waste water and harness the energy of water flowing in the supply network. (Click on the image to enlarge it, to see the detail).

Transition to an ecologically sustainable future needs global cooperation but also local attention to detail in every aspect of the city’s life and work. Now more than ever it’s time to ‘think globally and act locally’.
