Within the overall competition that produced the Green List five smaller contests took place:

- Big and mid-sized companies (with more than 250 employees) with high environmental impact (14 companies in this category made the overall top 60);

- Big and mid-sized companies with medium environmental impact (11 companies);

- Big and mid-sized companies with low environmental impact (11 companies);

- Small companies (with between 50 and 249 employees) with high and medium environmental impacts (18 companies);

- Small companies with low environmental impact (six companies).

Two new awards will be made this week recognising the special challenges facing larger companies trying to be greener:

- Best big company for corporate environmental strategy;

- Best big company for employee engagement.

And from them all, one firm will be chosen for the ultimate accolade: best green company in Britain.

The competition attracted businesses ranging in size from supermarket Tesco with 185,000 employees to office-supplies firm Wiles Greenworld with 50.

The top 60 remained balanced in terms of size with 12 big companies (with 5,000 or more employees), 23 mid-sized firms (with 250 to 4,999 employees) and 25 small enterprises (with 50 to 249 employees).
