In 1997, the Garden installed one of the first Compressed Natural Gas (CNG) Stations and converted our fleet of diesel trams and other Garden Vehicles, reducing Greenhouse Gas (GHG) emissions by 48% in these vehicles. We are also using smaller electric vehicles (golf carts, utility carts) to replace gasoline fueled pick-up trucks and vans. Most recently, the Garden was awarded a grant for two electric trucks through a program with the NYS Attorney General’s office.
Also in 1997, the Garden’s major heating plants (Conservatory and Library) were converted from #4 heating oil to dual fuel (natural gas/oil). The primary fuel, natural gas, has a 51% lower GHG emission than #4 heating oil.
Every year since 2007, the Garden performs a carbon audit that measures how much GHG emissions we produce. Since establishing our baseline (2MT eCO2 with a building area of 412,000 square feet), we have decreased our emissions by 53% while increasing our building area by 90% (due primarily to the addition of the parking garage).
