Combating climate change will need everyone individually to change the way they live their lives and the first step towards a more sustainable lifestyle is to monitor your own impact on the environment.
Global environmental consultancy WSP Environment & Energy created the Personal Allowance Carbon Trading scheme (PACT) to enable its employees to do just that. Not only can they track their carbon impact, but there are rewards for those who meet the company-wide target - and penalties for those who fail.
PACT is a voluntary scheme that was designed to support the company's own environmental commitment and to engage staff. It was launched in 2007 with a pilot in the UK operation of WSP's Environment and Energy division, and has since been taken up by other divisions of the group and at locations overseas such as Dubai and South Africa. It's been so successful, in fact, that a number of other organisations, including Cisco UK, Invensys Rail, five London boroughs, renewable energy supplier Good Energy and the Petroleum Institute in Abu Dhabi, have taken the scheme under licence for their own employees.
