The Net-Zero Carbon Buildings Declaration has been signed by the leaders of nineteen global cities as a pledge to significantly cut greenhouse gas emissions (GHG) by ensuring that new buildings operate at net zero carbon by 2030.
Eight American cities committed to this sustainability goal are Los Angeles, New York City, Newburyport, Portland, San Francisco, San Jose, Santa Monica and Washington D.C. The Mayors also pledged to ensure all buildings in the cities, old or new, will meet net-zero carbon standards by 2050.
“Climate change poses an existential threat to New York City, and making our buildings more sustainable and efficient is a key part of the solution,” said Bill de Blasio, Mayor of New York City. “With this commitment, we’re delivering on our promise to make New York City cleaner and safer for generations to come by meeting the Paris agreement. We’re proud to stand alongside other cities worldwide that are taking bold and meaningful steps to cut the pollution driving climate change.”
Net-Zero buildings use energy ultra-efficiently and meet any remaining energy needs from renewable sources. These commitments, made ahead of the Global Climate Action Summit in San Francisco, are important steps in delivering on the highest goals of the Paris Agreement and keeping global temperature rise below 1.5℃.
Each signed city will establish a roadmap to reach net zero carbon buildings, develop a suite of supporting incentives and programs, report annually on progress towards meeting targets, and evaluate the feasibility of reporting on emissions beyond operational carbon (such as refrigerants).
This pledge is also part of the World Green Building Council’s Net Zero Carbon Building Commitment for Businesses, Cities, States and Regions.
One comment on “Eight U.S. cities pledge to be net-zero carbon by 2030”
I am not aware of utility-capacity battery storage facilities that would provide satisfactory backup power for the times when “the sun don’t shine and the wind don’t blow.” Therefore, what would provide the zero carbon backup power? This all sounds like a wish and a prayer. Electric power may become very expensive in those cities. Or is this simply a “paper thing” where you buy zero carbon credits. Wind & solar may have only a 20% capacity factor. Therefore, wind & solar generation must be overbuilt in order to provide sufficient credits, and natural gas-fired combined cycle power plants (CCPP) still need to be built for backup power. Since wind & solar will be given priority, the capacity factor of the CCPP units will be horrible, making EVERYTHING more expensive. Who gets hurt first and hardest with more expensive electricity? THE POOR! Very sad.
