UBoC Carbon Calculator

UBoC Carbon Calculator

This calculator was developed by United Bank of Carbon (UBoC), University of Leeds, and Carbon Green.
It estimates one person's carbon footprint for one year and is valid for UK residents only.

What is a Carbon footprint?

A carbon footprint is defined as the total emissions caused by an individual, event, organisation or product, expressed as carbon dioxide equivalent (meaning that other greenhouse gasses are also accounted for).

How accurate is this?

A truly accurate figure can only be found by answering a lot of very difficult questions, which can put people off. So this calculator uses a representative set of easy-to-answer 'indicative' questions and UK Government data, to provide a fair estimate of one person's annual footprint.

Domestic 2: How many people (aged 17 and over) live in your house?

The calculator divides household energy use by occupancy. If it divided by everyone in the house, large families would seem to have a smaller average footprint than they should. So the calculator divides by the number of adults, because they are in charge of most of the decisions.
