As the City of Ithaca considers possible next steps on climate action, it would do well to look downstate for inspiration. On April 18 the New York City Council passed a sweeping “Climate Mobilization Act” to fight climate change, a package of seven bills that supporters said would help build a “Green New Deal for New York City.” The legislation passed by a 45-2 vote.

• Requires green roofs, solar panels, and/or small wind turbines on certain buildings
• Establishes a renewable energy and energy efficiency loan program
• Streamlines the application and siting process for wind turbine installation across the city
• Orders the city to carry out a study on the feasibility of closing its 24 oil- and gas-fired power plants and replacing them with energy storage and renewable power

“This legislation will radically change the energy footprint of the built environment and will pay off in the long run with energy costs expected to rise and new business opportunities that will be generated by this forward thinking and radical policy,” said Timur Dogan, an architect and building scientist at Cornell University.

As the New York Times observed in its coverage of the story, “Buildings are among the biggest sources of greenhouse gas emissions because they use lots of energy for heating, cooling and lighting, and they tend to be inefficient, leaking heat in the winter and cool air in the summer through old windows or inadequate insulation.” An inventory published in 2017 of greenhouse gas emissions in New York City found that buildings accounted for two-thirds of the city’s overall emissions.

It is for this very reason that TCCPI moved in 2016 to establish the Ithaca 2030 District as its new flagship program, joining a network of 22 cities in North America seeking to improve the energy and water performance of their downtown commercial buildings. Currently, the network has 493 million square feet committed. New York City is in the process of also establishing a 2030 District in Downtown Brooklyn and Lower Manhattan, and it should soon be up and running.

The Ithaca Green Building Policy marks a significant step towards encouraging new development projects to become more environmentally sensitive. As the policy enters the process of codification, however, it is important to remember that the overwhelming majority of commercial construction in the city is made up of already existing buildings. How does Ithaca intend to address this issue? The Climate Mobilization Act just passed by the New York City Council points the way.
