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 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. Energy from business air travel is based on short, medium and long haul flight segment fuel consumption.
Our total energy use decreased 3.8 percent between 2009 and 2011, or decreased by 14.5 percent when normalized by sales.
The company's Sustainability 2015 Goals include reducing total energy use by 15 percent from a 2009 baseline.
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 July 2010, approximately 90 percent of PCs in the U.S. and 82 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. The print volume in the first quarter of 2010 represented a 13% reduction in volume.
- Mobile Workforce Program: Take 10 cars off the road by 2010. By 2010, we achieved our goal to have 10 IT personnel working from home, thereby eliminating 100,000 personal vehicle miles per year, and by the end of the year roughly 80 employees were in the IT mobile workforce program.
- 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. As of the second quarter of 2010, 44% of discarded assets were sold or recycled.
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.
A position of Director, Global Energy Services has been established with worldwide responsibility. An energy management program is maintained and updated based on the characteristics of specific operational situations. 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, 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 are operating with a structured Energy Management System approach to deliver sustainable energy efficiency. The sites are committed to energy and carbon emissions reductions. The reduction of energy is a core objective for both sites and receives the full support of the Senior Management Team. The benefits of a structured approach to energy efficiency can clearly be seen by the successful reduction of energy usage at both sites. From 2008 – 2011 there has been an energy reduction in excess of 16%, and this was at a time when manufacturing output increased. As a result of energy initiatives over the last three years, the Irish sites have used an estimated 27 mm KWh less of energy, equating to an estimated carbon footprint reduction in excess of 10,000 tonnes. 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. Both sites continue to look for innovative ways to provide sustained reduction in energy usage and emissions of carbon dioxide to the atmosphere.
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 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.
Our technical operations plant 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 produce about 37,500 kilowatt-hours per year of electrical energy, which correlates to a greenhouse gas reduction of 15,000 kilograms per year.
At our onsite child development center in Hopewell, New Jersey, we installed a solar photovoltaic system that has generated approximately 1,100 gigajoules of energy and reduced carbon dioxide emissions by more than 148,000 kilograms since start-up in late 2004.
In 2011, the total amount of energy generated by Bristol-Myers Squibb facilities on site was 1.6 million gigajoules. In 2011, we generated 342 gigajoules of energy through renewable energy sources.
