There are various websites that calculate this for you. I chose co2.myclimate.org as the site is easy to use and they don't seem to have any obvious axe to grind. They also explain how they have worked things out.
Adding up the six flights, I have generated about 4.4 tonnes of Carbon Dioxide.
What percentage of my overall carbon footprint is this?
- Driving the car for a year is about 4 t.
- Living where I do and following my lifestyle is about 8.1 t and
- Breathing for a year is about 0.3 t.
According to myclimate.org, if I:
- Always travelled by public transport, cycled or walked (saving - 1.8 t)
- Never flew (saving - 4.4 t)
- Only eat vegetarian food (saving - 1.2 t)
- Very rarely bought new products, clothes or decorative items (saving - 0.2 t)
- Moved to an energy efficient building (saving - 1.6 t)
- Only took quick showers (already doing it)
- Wore a pullover in winter when I am at home (already doing it)
- Stop breathing (hang on a minute - don't include that!)
If I don't make these changes, can I offset 13.5 tonnes of Carbon?
The most popular ways of offsetting are:
- Replacing fossil energy sources with renewable energy or by promoting energy-efficient technologies.
- Contributing to social, ecological and economic development projects.
- Purchasing Carbon Credits
So would it help if I stopped flying? Errr. Not really. No.
1) HF Holidays would send a different walks leader
2) The plane would fly anyway
3) We'd still be heading for a Climate Catastrophe
Stopping the Climate Catastrophe won't be done by carbon offsetting or a few people flying less.
We need to:
- Shift to renewable energy sources like tidal power
- Provide free public transport as an alternative to driving and flying
- Stop destroying forests for intensive agriculture
- Create protected areas in the oceans in which sea life can flourish
- Encourage people to appreciate their environment and enjoy walking (already doing it)
I guess I'm willing to do things that are easy to do but not things that would have a big impact on my life like becoming a vegetarian or not flying. If there was a genuinely easy alternative, I would use it.
