I came accross this article about carbon footprint in Haring Ibon, issue 32 by Dominic Gonzales of Manila Waldorf School. I have been seeing about this over the web but never really understand it, let's educate ourselves...
A carbon footprint is a measure of the impact our activities have on the environment, and in particular climate change. It relates to the amount of greenhouse gases produced in our day-to-day lives through burning fossil fuels for electricity, heating and transportation etc. The carbon footprint is a measurement of all greenhouse gases we individually produce and has units of tonnes (or kg) of carbon dioxide equivalent.
A carbon footprint is made up of the sum of two parts, the primary footprint and the secondary footprint.
Primary Footprint
The primary footprint is a measure of our direct emissions of CO2 from the burning of fossil fuels including domestic energy consumption and transportation. We have direct control of these.
Breakdown (46%):
1. Home: a. Gas, oil and coal (15%), b. Electricity (12%)
2. Transport: a. Private (10%), b. Public (3%), c. Holiday flights (6%)
Secondary Footprint
The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use - those associated with their manufacture and eventual breakdown. To put it very simply – the more we buy the more emissions will be caused on our behalf.
Breakdown (54%):
1. Food and drinks (5%)
2. Clothes and personal effects (4%)
3. Car manufacture and delivery (7%)
4. House - buildings and furnishings (9%)
5. Recreation and Liesure (14%)
6. Financial services (3%)
7. Share of public services (12%)
Well we do now clearly see how vastly we affect the climate change with our little doings. So reduce you carbon footprint and do your part!
