It’s important that we feel that we’re fighting this crisis like our lives depend on it, because in fact they do,” said New York mayor Bill de Blasio, announcing the city’s latest energy mandate, which will require about 14,000 buildings to upgrade their boilers, windows, roofs, and water heaters. Hyperbole on climate change is nothing new to de Blasio or to Governor Andrew Cuomo—and it’s necessary to help justify their claims that New York can cut its greenhouse-gas emissions 80 percent by 2050. Both leaders have signed on to the Under 2 MOU, an agreement between states, cities, and provinces worldwide that commits signatories to slash emissions by 80 percent, or to less than two tons per capita per year.
At his September news conference at Brooklyn Bridge Park, de Blasio made it clear that the new regulations on older buildings are just one part of his “80 x 50” plan. Cuts in carbon-dioxide emissions, he said, “would be achieved either by a voluntary action of the private sector or by mandate.” De Blasio likes mandates. The new ones—subject to city council approval—would require landlords to complete building retrofits by 2030 or face stiff fines.
Even if we stipulate that increased energy efficiency in New York buildings is a good thing, the emissions-reduction targets are financially burdensome and unrealistic. Cuomo’s appointees at the New York State Public Service Commission have mandated that buildings must slash their energy use by 600 trillion BTUs by 2030. But as economist Jonathan Lesser points out in a recent report for the Manhattan Institute, the New York Independent System Operator has projected that those energy savings will be about 51 trillion BTUs—or about one-twelfth the required amount.
