A simple emissions calculator for households, businesses or workplaces, providing a general sustainability indicator. Based on your answers to a quick online survey, you get a Green Street score indicating whether you are a low, moderate or high contributor. The tool has been validated externally against global standards and endorsed by the United Nations Global Compact Cities Programme.

You will be asked to do your Green Street Score when you join Green Street as a household or business/workplace. After scoring, you will see some suggested ways to improve household and workplace sustainability. You can add some of these to your pledge, which is displayed on your profile. A personalised Green Street Certificate is automatically generated when your Green Street Score is finalised – you can print or share this as a reminder of your pledges.

The Green Street Score is a way for businesses and households to assess their level of sustainability, and see suggestions on ways to lower emissions. Members can use the calculator regularly to reassess their scores and make new pledges.

Everyone! Households, businesses and other enterprises, large or small.

To use the online calculator and get a Green Street score, join Green Street, or sign in if you are already a member.
