The Yankees are committed to helping promote a sustainable environment and have implemented many green initiatives at Yankee Stadium.
In March 2009, Yankee Stadium purchased over 33 million kilowatt-hours in renewable energy certificates (RECs) - meeting 100% of the stadium's purchased electricity usage for the next two years. Hess Energy, the stadium's supplier, leverages its bulk buying power and skilled team to purchase enough certificates from high-quality, green energy producers to help the Yankees reach their green goals. Renewable Energy Certificates allow any customer, anywhere in the country to support renewable energy generation. For every REC purchased, one megawatt-hour (MWh, or 1000 kilowatt-hours) of renewable electricity is generated and delivered to the power grid. When you buy a REC, you are investing in the future development of renewable energy sources, and making a commitment to support greener sources of power.
Later in 2009, the Yankees became an early adopter of another Hess Energy product, C-Neutral. Through C-Neutral, the team is able to completely neutralize the greenhouse gas emissions associated with their natural gas energy consumption. Carbon Offsetting is a way to compensate for greenhouse gas emissions by investing in sustainability projects across the country and around the world. These projects can range from the development of renewable energy sources and energy efficiency technologies to agricultural and reforestation initiatives. Working with the information provided by the Yankees, Hess engineers completed the calculations to determine the environmental impact of the energy used at the stadium throughout the year. These calculations generated the number of carbon offsets that would be required to make the Yankees' operations carbon neutral while providing the best value.
The sustainable efforts of the Yankees are the equivalent of taking more than 4,700 passenger cars off the road for a year. Together, the Yankees and Hess are proud to be working as a team to do their part to address the growing climate concerns.
Each lighting fixture above Yankee Stadium consumes approximately 300 fewer watts than a typical stadium fixture and has a 50 percent reduction of "light spill" onto adjacent property. Control systems and building automation increase the lifetime of the lighting system. These improvements mean that during one night game, nearly 207,000 pounds of CO2 emissions are saved. That's the equivalent of about one tree being planted for every pitch of the home season.
This program ensures the efficiency of equipment while focusing on energy reduction. Instead of petroleum-based plastics, beverage cups are made of biodegradable material. Waste generation is tackled through composting and recycling cardboard, glass, metal and plastics/paper and should divert more than 80 percent of Yankee Stadium's trash away from landfills. This also results in fewer trash pickups and trash trucks on the road.
The different systems used to operate Yankee Stadium are calibrated to the specific usage patterns of the Stadium and reduce the power consumption of lighting and ventilation systems when they're not needed.
The Great Hall will not have air-conditioning, instead relying on natural cooling. The savings is about the same as 10,000 New York City apartments shutting off their air-conditioning for a summer day.
Each year, Yankee Stadium's plumbing fixtures are projected to save 3.1 million gallons of water and reduce Yankee Stadium's water consumption by 22 percent. Additionally, Yankee Stadium uses GoJo hand soap, which doesn't require water for use. Close to 1 million gallons of water will be saved per season if every guest uses this soap.
The Yankees are committed to purchasing only paper products made from 100 percent recyclable paper. Yankee Stadium is the first major league ballpark to commit to keeping all of its operations and maintenance manuals 100 percent electronic. This saves 10 trees, 100 pounds of solid waste, 1,000 gallons of waste water and 10,000 kilowatt-hours of electricity.
Yankee Stadium is located within close proximity of the subway, Metro-North, buses and other mass transportation systems. Guests and employees are encouraged to utilize public transportation in order to reduce CO2 emissions and reliance on foreign oil.
Yankee Stadium has recycled 8,879 gallons of cooking oil from Yankee Stadium this year to date. This oil has been used to produce 7,192 gallons of biodiesel fuel. When used in vehicles, this biodiesel will displace 129,455.8 pounds of carbon emissions. That is the equivalent of removing 11.76 cars from the road for a full year.
