The BBCA Association has just launched the BBCA Quartier label, a method for measuring and promoting exemplary low-carbon practices on a neighborhood scale. By placing the user at the heart of its principles, the BBCA Quartier label responds to the dual challenge of decarbonizing the act of development (construction, energy, planning) while providing users with a low-carbon living environment by taking into account mobility, food and consumption practices. The label is based on a performance approach, with emission ceilings that must not be exceeded.
