HOW IT WORKS

There are five categories for organisations taking part in our unique two-part survey:

- Big and mid-sized companies with a high environmental impact;

- Big and mid-sized companies with a medium environmental impact;

- Big and mid-sized companies with a low environmental impact;

- Small companies with a high or medium environmental impact;

- Small companies with a low environmental impact.

The Green List brings together the best businesses from all five categories to produce an overall winner.

There are several special awards that cover everything from the greenest workforce to the best environmental strategy.

Green List companies last year employed between 50 and 185,000 staff and represented industries as diverse as retailing, media, leisure, construction, and oil and gas exploration.

Unlike any other environmental contest, we recognise that corporate policies count for little if they are not adopted by staff. So while the first part of our survey looks at green policies, the second part (accounting for 30% of the final score) lets staff tell us how they think their firm measures up.

Don’t be put off if your company has a large carbon footprint or if its line of business means that energy consumption is unavoidably high. It is the commitment to change and evidence of a genuine desire to be more environmentally friendly that will earn a company a place on the 2010 Green List.

Registration remains open until February 19.
