New buildings in 19 global cities, including London, Los Angeles, New York City, San Francisco, Tokyo and Paris, will have zero emissions by 2030, with existing buildings becoming zero carbon by 2050.
The mayors of the 19 cities signed the Net Zero Carbon Buildings Declaration in London, to help their metropolises significantly cut their greenhouse gas emissions in line with the requirements of the Paris Climate Agreement.
Net-Zero Buildings use energy ultra-efficiently and meet any remaining energy needs from renewable sources. “Such bold commitments, made ahead of the Global Climate Action Summit in San Francisco, are essential steps in delivering on the highest goals of the Paris Agreement and keeping global temperature rise below 1.5C” said the C40 Cities initiative, a group of cities committed to taking bold climate action, which co-ordinated the initiative.
