Empire State Building and Others in Owner's Portfolio Go All Green

This will prevent the production of carbon dioxide

As part of the deal, ESRT will be purchasing more than 300 million kilowatt-hours (kWh) of renewable energy to cover their energy use.

"We have purchased renewable power from Green Mountain Energy for the World's Most Famous Building, the Empire State Building, for a decade. We now expand that to all properties in New York State with an additional Direct Energy contract for our Connecticut properties. We continue to advance our commitment to solutions that reduce our environmental impact. Our tenants now work in carbon neutral offices and the investment community can recognize our leadership," said Dana Robbins Schneider, SVP, director of energy, sustainability & ESG at Empire State Realty Trust said in the press release.

ESRT states that this switch will prevent the production of 204 million kg (450 million lbs) of carbon dioxide, which is, according to the company, the equivalent of removing all of NYC’s taxis for a year, turning off every household light in the city for a month or adding two Central Parks.

"At Green Mountain, we’re encouraged by the sustained and vocal advocacy from Empire State Realty Trust that continues to lead New York’s transition to renewable energy," said Mark Parsons, vice president and general manager of Green Mountain Energy, further explaining that their mission is to "use the power of consumer choice to change the way power is made, and we are committed to helping New Yorkers reduce their carbon footprint.”
