Energy Conservation
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, gasoline, propane, fuel oil, coal and natural gas. The vast majority of the fuel consumed by our facilities is natural gas, which produces less air pollution than coal or fuel oil. In addition to the fuel used on-site by our facilities (categorized as direct energy use), we also track indirect energy, which includes the electricity purchased by Bristol-Myers Squibb.
Our total energy use (including direct and indirect energy use) decreased 17 percent between 2007 and 2008, or by 27 percent when normalized by sales.
The company's Sustainability 2010 Goals include reducing energy use by 10 percent, normalized by sales, from a 2001 baseline. From 2001 to 2008, our total energy use decreased by 21 percent, and decreased by 40 percent when normalized by sales.
Our direct energy use at our operations decreased by nearly 13 percent from 2007 to 2008, or 23 percent when normalized by sales. Overall, our indirect energy use decreased by 20 percent from 2007 to 2008, and by 29 percent when normalized by sales.
Green IT Initiative
The Green IT (information technology) Initiative was designed in 2008 to help track and expand efficiency projects – with the goal of reducing IT-related energy use, waste and greenhouse gas emissions. The initiative focuses on five core IT areas:
- Data Center: Reduce energy use by 10 percent by 2010 through facility power management, server asset layout and virtualization – the hosting of several applications on one server.
- Green PCs: Eliminate all screensavers and convert 100 percent of PCs and laptops to “green standards” based on the Electronic Product Environmental Assessment Tool (EPEAT) and IEEE 1680 Standard for Environmental Assessment of Personal Computer Products for personal desktop and notebook computers and monitors. Considerations include U.S. Environmental Protection Agency ENERGY STAR rating, design for recovery through recycling, degradability, reduction of hazardous substances and recycled material content. As of June 2009, approximately 64 percent of PCs in the U.S. and 54 percent of PCs globally (including the U.S.) conform to the company’s green standards.
- Think before you print: Reduce paper consumption by 20 percent, beginning with a pilot program at Nassau Park, New Jersey. Explore using 30 percent recycled paper on 10 percent of all printers by 2010. Reduce printer standby time from six hours to 30 minutes.
- Mobile Workforce Program: Take 10 cars off the road by 2010. By 2010, our goal is to have 10 IT personnel working from home, thereby eliminating 100,000 personal vehicle miles per year.
- Third-party vendors: Audit Bristol-Myers Squibb business partners, who currently own our hardware, to adhere to green standards. Green IT standards will be added to existing third-party audits and will include energy savings and asset disposal.
The Green IT Initiative is expected to reduce the company’s annual greenhouse gas emissions by nearly 10.4 million kg of CO2 equivalents, reduce annual energy use by 38,000 kilojoules and remove the equivalent of more than 1,740 cars from the road.
Energy Program
Each division is required to develop and maintain an energy management program based on the characteristics of its operations. The corporate environment, health and safety department reviews these programs annually and reports findings to senior management. Program objectives are supported by a number of other company initiatives that address energy issues, including our EHS Policy, acquisition due diligence, review of capital investments for EHS impacts and green chemistry reviews. As a result, our new facilities typically make use of state-of-the art, energy-efficient technologies.
Both our Swords and Cruiserath facilities in Ireland are implementing an IS393 Energy Management System, an Irish initiative that follows an approach similar to ISO 14001. At each site, a dedicated team reviews energy reduction and management opportunities. As a result, the sites reduced their estimated combined carbon dioxide emissions nearly 12,000 tonnes through June 2007. Energy usage at the Cruiserath facility has increased by only 10 percent despite annual production output increasing by 50 percent over the past few years. The facilities received a Responsible Care award for their Integrated Energy Reduction Program from PharmaChemical Ireland Responsible Care Award.
Bristol-Myers Squibb’s Wallingford, Connecticut, facility is voluntarily participating in the U.S. EPA and Department of Energy Labs 21 Program, to improve laboratory energy and water efficiency by encouraging the use of renewable energy sources. The Wallingford facility—a one million square-foot pharmaceutical research and development center covering 180 acres—requires large amounts of energy. The facility constructed a combined heat and power (CHP) plant that uses clean-burning natural gas and a heat recovery system in the form of a waste heat boiler. The CHP system operates at approximately 72 percent efficiency, more than double the estimated efficiency rate of the entire 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 tonnes per year.
Currently, several of our facilities around the world have systems that generate electricity on site, including Hopewell, Princeton and New Brunswick, New Jersey; Wallingford, Connecticut; Delicias, Mexico; Guayaquil, Ecuador; Karachi, Pakistan; Anagni, Italy; and São Paulo, Brazil. 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.
In 2007, our technical operations plant in Anagni, Italy, installed solar panels over 80 square meters of the facility's rooftop. The system feeds directly into the Italian energy network, which in turn gives the Anagni facility the equivalent amount of energy. This project offsets greenhouse gas emissions of 9,700 kg per year. By the end of 2007, a second set of solar panels was installed to run the mechanical systems at the site’s wastewater treatment facility, which will deliver approximately 135 gigajoules of energy per year and further reduce annual carbon dioxide emissions by 15,000 kg.
At our onsite child development center in Hopewell, New Jersey, we installed a solar photovoltaic system that has generated approximately 470 gigajoules of energy and reduced carbon dioxide emissions by more than 43,000 kg since start-up in late 2004.
The 18.6 million kg of carbon dioxide emissions avoided annually by the five projects described above is equivalent to removing more than 3,400 passenger cars from the road or 43,000 barrels of oil from distribution each year (based on U.S. EPA’s Greenhouse Gas Equivalencies Calculator). In 2008, the total amount of energy generated by Bristol-Myers Squibb facilities on site was nearly 1.7 million gigajoules. We also generated 117 gigajoules of energy through renewable energy sources.
