Cisco is to ration the amount of carbon its employees are allowed to use.

The trial, set to start next year, will see the company’s departments allocated with a ‘budget’ of how much carbon they should use.

“We are going to try and give out a carbon budget next year,” said Chris Dedicoat, president of European markets. “It’s going to be our way of focussing people to look for alterative ways of doing things. By using metrics, they will see everything they do has an environmental impact.

“I will be interested to see what people say with a carbon budget.”

If the company follows traditional models of carbon rationing, it could mean some departments trade their allowances, if they have enough left over.
