A survey of more than 1,800 UK office workers found that a third took no action to reduce the amount of resources they use during the working day.
'This research sends out a clear signal to UK businesses that good domestic environmental practices do not necessarily translate to the workplace,' said Mary Leonard, Envirowise's marketing director.
'By ensuring gas, electricity, water and recycling bills are not cloaked in mystery, staff will have a greater understanding of how their actions can help reduce costs.'
She added that the current financial climate should provide businesses with another incentive to cut their bills.
'With the credit crunch continuing to bite, cutting costs through better resource efficiency and minimising waste have never been more important,' Ms Leonard said.
'Those businesses that make positive changes to reduce their environmental impact and reduce costs now will be better equipped to survive and thrive during the current downturn.'
Envirowise recommended businesses should appoint 'champions' to lead environmental incentives, urge employees to switch off lights and computers at the end of the day, and install water saving devices in toilets and kitchens.
It has also recently produced a guide to help businesses decide whether rainwater harvesting would be a suitable way to save resources in their workplace.
