Using the npower carbon calculator
Your business may not yet be affected by legislation such as the Carbon Reduction Commitment Energy Efficiency Scheme, but as pressure grows – from both consumers and larger companies looking at the environmental credentials of their supply chain – it can be useful to have an idea of the CO2 emissions your business is responsible for.
We have therefore designed a Carbon Calculator to help you estimate your CO2 emission levels. For the sake of simplicity, the Carbon Calculator does not include emissions arising from processes such as cement and lime production, brewing, smelting aluminium or magnesium and certain chemical reactions.
Calculate your carbon footprint
Download the Carbon Calculator spreadsheet and complete the figures requested in the boxes. You’ll find tips on where to find this information alongside each box.
It doesn't matter if some of your data is not completely accurate at this stage. It can be refined later if emissions from that source prove to be important.
