Carbon Footprint Journal (2)

Last week I decided to eat less meat to make my carbon footprint drop. So I did. For the past week, I only ate three times meat. I also did my shopping on the market last Sunday and bought fresh vegetables and fruits. I realised that it cost me less money than buying at the grocery store.
I also bought some low-energy light bulbs for my bedroom.

Product follow-up: PAIC Citron

PAIC Citron is a hand washing-up liquid that is sold by Colgate-Palmolive.

The main constituents are these listed below:

C14-C17 Alkyl Sec. Sulfonate
Sodium Laureth-Sulfate
Lauryl Amidopropyl Dimethyl Amine
Myristyl Amidopropyl Dimethyl Amine oxide

Perfume
Preservatives

The company assures that all the chemical agents are biodegrable and it has been tested so.

The sulfate can be dangerous for humans and animals if it is swallowed in an important quantity. It is also a corrosive chemical.
I did not find more information on the preservatives that are in the liquid , although the danger they may represent is different from one another.

The challenge for the company is to produce a hand washing-up liquid from vegetal basis. They also have to work on making it the least corrosive as possible.
They can alos work on the packaging of the product to make it more environment friendly.

Carbon footprint journal

On March 12th I calculated my carbon footprint with WWF Ecological Footprint calculator. It  was up to 2.24 planets meaning that if everyone on the planet lived the same way as me 2.24 planets would be necessary to meet our needs of primary resources. It also told me that the way I live right now makes me produce 8.72 tonnes of carbon per year.


My food habits contribute to 23% of my carbon footprint. It seems like I eat too much meat per week and not enough fresh and local vegetables. I decided to improve this figure. I will try to buy and eat more fresh fruits and vegetables in the coming weeks and eat less meat.

Travelling contributes to 21% of my carbon footprint. This can be explained by the fact that I've been travelling by plane a few times this year. I did not go very far away, but I flew to London, Berlin and Madrid. It seems hard to make this figure lower. Travelling by plane remains cheaper than travelling by train and it is more practical.

My home contributes to 20% of my carbon footprint. I live in an old appartment down town Grenoble that I share with three roomates. So we have a good-size appartment. The appartment is not well isolated, for exemple there is no double glazing. Futhermore as the service charge is included in the amount of the rent, I do not really pay attention to my consumption regarding water and electricity. I can improve a lot on this. I just have to be more carefull about switching off my heating when the air is cooler outside and switching off the lights every time I leave a room.

Stuff contributes to 36% of my carbon footprint.I have bought several household items in the past few months (camera, cell phone,...). I also spend quite a lot of money on bath products and jewelry. My consumption in terms of bath products can be improved a lot because sometimes I buy products that I never use afterwards.
