What does the green / yellow / red banding mean?

The colour-coded banding that is presented throughout the app is based on the carbon intensity of your local electricity supply. The bands represent low, moderate and high carbon intensity. The numerical definitions of the banding are shown below.

Moderate (amber)

200-299

Low (green)

The average carbon intensity across the country has been steadily decreasing in the last five years. The following table shows an estimation of the historical average annual carbon intensity of UK electricity since 2012. The Committee on Climate Change estimates that the power sector should aim for an average carbon intensity of between 50-100g/kWh in order to reach the 2050 target of carbon neutrality.
