We think it's a good place to start. Not only is reusing Carbon Neutral, it is Carbon Negative.

That means, every time you buy a pre-owned / Used thing not only you don't harm the planet any further but on top of that you reduce the damage that has already been done to the planet by factories who mass produce new stuff using fossil fuels to make plastic (which is a petrochemical) or to generate electricity for their hungry power needs and much more.
