Me not getting my own signature is just a baseless thought of yours, with a sole purpose to insult.
Why should I have to prove my every word, when it doesn't seem to be a common requirement?
Before I made any claims about my carbon footprint, I actually took a test by government based foundation. And it concluded according to my fundamental choices, the carbon footprint was about half from average. It covered the basic stuff.
Of course the test didn't even consider my shopping habits. - when in need of something, prefer second hand and natural materials. Some over ten years old clothes are still in use, giving the rest to charity.
Most of our furniture are old, durable, gifted or recycled.
Cosmetics consumption minimum, prefer soap bars and organic makeup. Not dying my hair.
Buy immarerial gifts, or books for my kid's friends birthday parties - even if they cost more.
Buy simple food with no exessive plastic, it's also healthy for me.
Etc.
