Businesses in Scotland's two biggest cities rank climate change at the bottom of the list of their priorities, according to research.
The trust is urging Scottish businesses to reduce emissions
The government-funded Carbon Trust said 45% of firms in Glasgow and a third in Edinburgh were taking no action to cut carbon emissions.
Those businesses surveyed cited a lack of information and not knowing how to tackle the problem for their inaction.
John Stocks, from the Carbon Trust, said attitudes need to change.
The Survey Shop carried out the research on behalf of the Carbon Trust in May 2005, with 1,500 interviews conducted with 60 companies in 25 locations throughout the UK.
REDUCING CARBON EMISSIONS
Encourage staff to turn lights off where possible
Reduce workplace temperature by 1 degree
Switch off computers at night
Use air conditioning sparingly
Replace standard bulbs with low energy
In Glasgow, only 8% of businesses believed climate change would have a major effect on their organisation within the next five years.
Only a fifth of firms in Edinburgh thought climate change could hamper their performance.
Mr Stocks said the business sector as a whole should realise that acting on climate change could save firms money in the long-term.
"The extreme weather conditions that climate change can cause and the associated higher insurance premiums, coupled with legislation introduced to mitigate climate change, will affect business," he said.
"Businesses will soon see the benefits if they start taking measures to mitigate climate change - they will be helping not only the environment but also their bottom-line as cutting carbon and energy use will save them money."
