One in two employees say that they regularly lobby their workplace or employer to encourage greener business practices, according to a new U.K. survey from Fujitsu Siemens Computers.

Eighty percent of British workers believe that they're more environmentally conscious today than they were three years ago – and the majority of them are bringing their green consciences into the workplace, putting pressure on employers to do their part.

Employees are also taking matters into their own hands, the survey finds. Some impressive numbers:

• 71% percent of respondents turn off their PCs overnight, up 57% since 2005
• 82% recycle paper, an increase of nearly 62% over the last three years
• 37% reduce their daily fuel consumption by carpooling with a co-worker

"Our research shows that the gap between how green we are at home and how green we are at work is certainly closing," says Steve Kendall-Smith, managing director U.K. at Fujitsu Siemens Computers. "We hope that the increased lobbying from this now well-established group of 'green collar workers' can only help to continue to make many more U.K. businesses greener places to work in the future."

Companies are taking a wide range of approaches to meet employee demand for more green practices. WIPRO, India's leading IT provider, has developed "eco chapters" to engage employees on green issues so they can apply their learnings to company projects. Alcoa recently launched an interactive website to encourage employees to help the company manage its carbon footprint and reduce energy costs.
