Bristol-Myers Squibb collects and reports data on electricity and fuel use from our facilities worldwide. For worldwide fuel usage, our facilities track diesel fuel, propane, fuel oil, and natural gas. Gasoline consumption is tracked for our sales fleet. The majority of the fuel consumed by our facilities is natural gas, which is cleaner burning than fuel oils. In addition to the fuel used on-site by our facilities (categorized as Scope 1 direct energy use), we also track indirect energy (Scope 2), which includes the electricity purchased by Bristol-Myers Squibb. Energy from business air travel (Scope 3) is based on short, medium and long haul flight segment fuel consumption.
Our total energy use decreased 1.0 percent between 2013 and 2015, and decreased less than 1.0 percent when normalized by sales.
The company's Sustainability 2015 Goals included reducing total energy use by 15 percent from a 2009 baseline (excluding acquisitions - see footnote on Key Performance Indicators table). We have decreased total energy use by 13.1 percent absolute through 2015.
A position of Director, Global Energy Services has been established with worldwide responsibility. An energy management program is maintained and regularly updated. The corporate environment, health, safety and sustainability department reviews this program annually. Program objectives are supported by a number of other company initiatives that address energy issues, including our EHS Policy, review of capital investments and acquisitions for EHS impacts and green chemistry reviews. As a result, our new facilities typically make use of state-of-the art, energy-efficient technologies.
Our Swords and Cruiserath, Ireland facilities have reduced energy consumption from 2009 to 2015 by over 55 million kWh (23%) versus 2009 actual usage, equating to an estimated carbon footprint reduction in excess of 12,000 metric tons. Examples of the innovations introduced are: reductions in building air change rates, changeover to the use of “cold” standby boilers, modifications on incinerator burners to increase gas efficiency and the installation of variable speed drives on large site motors.
The Wallingford, Connecticut facility—a one million square-foot pharmaceutical research and development center situated on180 acres—requires large amounts of energy. The facility constructed a combined heat and power (CHP) plant that uses clean-burning natural gas and incorporates a waste heat boiler as a heat recovery system. The CHP system operates at approximately 72 percent efficiency, more than double the estimated average efficiency rate of the U.S. electric system. The CHP system, which recovers heat from the gas turbine to make steam for heating the complex during the winter months, has reduced greenhouse gas emissions at the Wallingford facility by approximately 20 percent—or about 6,600 metric tons per year.
Currently, several of our facilities around the world have systems that generate electricity on site, including Hopewell and New Brunswick, New Jersey; Wallingford, Connecticut; and Anagni, Italy. Some of these locations have cogeneration facilities on site. Cogeneration produces electricity plus steam or hot water for site operations using one fuel (typically natural gas), thereby greatly increasing efficiency and decreasing the site's use of purchased electricity. Additional cogeneration opportunities across the company are currently being evaluated.
Our manufacturing facility in Anagni, Italy installed solar energy photovoltaic systems to provide electricity to its offices and the facility’s wastewater treatment plant. More than 480 square meters of rooftop solar panels provide power and reduce greenhouse gas emissions. The solar panels produced about 47,000 kilowatt-hours of energy in 2015, which correlates to a greenhouse gas reduction of 18,600 kilograms per year.
At our onsite child development center in Hopewell, New Jersey, we installed a solar photovoltaic system that has generated approximately 622,144 kilowatt hours of energy and reduced carbon dioxide emissions by more than 437 metric tons since start-up in late 2004.
Also in Hopewell, New Jersey, we installed a solar photovoltaic system on the roof of our parking deck that has generated approximately 1,895,000 kilowatt hours of energy and reduced carbon dioxide emissions by more than 1,332 metric tons since start-up in early 2014.
In 2015, the total amount of energy generated by Bristol-Myers Squibb facilities on site was 3.4 million gigajoules. In 2015, we generated 4,100 gigajoules of energy through renewable energy sources.
