– Roche Pharmaceutical says it will buy 20 hybrid vehicles as part of the company's commitment to lower greenhouse gas emissions by 10-percent over the next five years.Roche is integrating Toyota Prius and Ford Escape hybrid vehicles into its pharmaceutical sales fleet. This initiative is also an ongoing attempt to continually improve business practices. Initially, 20 sales representatives are involved in the pilot program. These vehicles are expected to emit up to 97-percent fewer hydrocarbons and oxides of nitrogen than vehicles, which currently meet today's nationwide Tier I standards. In addition these vehicles will significantly reduce carbon dioxide emissions, a known greenhouse gas. “We plan to continue to add hybrids and other fuel efficient vehicles into the 1,400 car sales force and eventually replace our entire fleet,” said Jack Kace, vice president, Corporate Environmental & Safety Affairs.Roche has been active in instituting environmentally friendly programs for years, including using recycled products and recycling appropriate materials. In addition, the company sponsors sustainability and energy awareness days to encourage all employees to be environmentally responsible. Roche Corporate Environmental & Safety Affairs (CESA) has recently joined forces with the EPA Climate Leaders Program. Climate Leaders is a voluntary industry-government partnership that encourages companies to develop long-term comprehensive climate change strategies and set greenhouse gas (GHG) emissions reduction goals.
