CIBSE’s campaign to encourage businesses to cut down on their carbon emissions has finished.

The 100 Hours of Carbon Clean-Up campaign challenges participating businesses to commit 100 hours of staff time to carbon-reduction activities, which includes assigning one member of staff to be their designated ‘low carbon champion’.

The businesses signed up to the campaign had 3 months to complete their 100 hours. This year’s campaign was the institute’s third consecutive carbon reduction campaign and saw around 500 businesses sign up.

The end of campaign party was held at Surya, which claims to be the world’s first eco-club.

CIBSE Chief Executive Stephen Matthews said: “Once again we have been impressed with the level of enthusiasm and dedication displayed by participants and wish them every luck in their continued efforts to reduce the amount of carbon emitted from the workplace. With the current economic climate, the energy efficiency of buildings will increase in importance as people look to cut energy bills and work towards a more sustainable future.”
