By “significant” you actually mean “insignificant”.

No less than three of these pieces of advice assume you already own a car. Tell me — how much greenhouse gas would you actually save by following this advice? I can tell you from the article — less than 20% of the amount produced by your car alone.

To put it another way — if everyone did all these things, it might account for as much as two years’ growth in greenhouse gases — in other words, it would delay the climate catastrophe by two years.

And the article quite reasonably points out that getting even 10% compliance on this would be ambitious.

The idea that we can fix the problem of exponentially growing consumption and exponentially growing waste by tiny, convenient, basically unnoticeable changes to our lifestyles is a delusion.

There are a billion gasoline powered cars on the planet. For us to avoid the worst effects of climate change, we have to take those cars off the road. We can’t just tune them up, pump up the tires, and happily go on driving everywhere as if we’ve solved the problem.

Everyone seems to think that we can fix everything by just buying a package with a green sticker or inflating our tires, and not actually have to give anything up or exert any great effort.

Your article is yet another example of how deep we are in self-delusion. I have to say that it made me despair, rather than hope.
