Pharmaceuticals company Merck reduced its absolute carbon emissions by 5 percent year-on-year, from 2.2 million metric tons of CO2e in 2010 to 2.09 million in 2011, according to the firm’s latest sustainability report.
In the same period the company’s total energy use fell 3.3 percent, from 27.1 trillion to 26.2 trillion BTUs. Over that time the company increased the proportion of its energy it draws from natural gas from 54 percent to 60 percent, and reduced the proportion of its energy use attributable to fleet fuel from 12 percent to 10 percent.
Seven Merck sites installed solar arrays in 2011. Together they eliminated over 2,500 metric tons of CO2 emissions, the report says. The company also installed two 2 MW wind turbines at its Cramlington, UK, site in late 2010.
