Climate change is a serious problem that affects us all. There is strong evidence that human emissions of greenhouse gases are also changing the world’s climate. The main greenhouse gas is carbon dioxide (CO2), produced when we burn fossil fuels like coal, oil and gas for energy.
A carbon footprint is the amount of greenhouse
gas a country, business, product or individual is
responsible for emitting.
So, if you divide the 650 million tonnes figure by the number of people who live here in the UK it is estimated the average carbon footprint is about 11 tonnes per person. To help you workout your own carbon footprint there are lots of on line calculators you can use. Why not take a look at the Act on CO2 calculator at: www.actonco2.direct.gov.uk/index.html
Sending one item through the mail generates an average of 26g of CO2. The amount of energy required to power a computer for one minute produces 1.8g of CO2. Thus, one hour’s use of a computer produces 5 times as much carbon as is produced by the delivery of one letter.
At just 0.01kg of carbon per letter per person per year, a normal letter still represents good carbon value, especially relative to other forms of communication; mobile-phone chargers alone account for between 35kg to 70kg of carbon per person per year.
