Empire Building Challenge Partners


The Empire Building Challenge is built on successful public-private partnerships, which are crucial to advancing New York’s goal of a carbon-neutral building stock as we grow the State’s green economy. The following 16 real estate portfolio owners collectively control over 228 million square feet of commercial and multifamily real estate in New York, including more than 70,000 housing units. Through the Empire Building Challenge, these partners have made commitments to rapidly accelerate their decarbonization efforts with the goal of achieving carbon neutrality. Decarbonization actions taken by Empire Building Challenge partners will help to set a precedent for replicable low-carbon demonstrations that will inform the next decade of real estate investment in energy efficiency, sustainability, and healthy indoor environments.

2022 Partners

Six new partners have joined the Empire Building Challenge in the Fall of 2022. Together, these partners control 94 million square feet of New York real estate and have pledged carbon neutrality in 72 million square feet. Within their expansive portfolios, these partners are advancing eight showcase buildings through the Program, comprising 5.6 million square feet across a range of diverse building typologies. Their commitment to reach carbon neutrality by 2035 will support New York State's climate goals, help to grow the green economy, and underscore the potential for scalable and replicable retrofits across the State.
