Sainsbury’s cannot say they will be carbon neutral by simply ignoring the consequences of its own actions. Doing so is, in fact, is a caricature of the denial implicit in the whole climate crisis to date, where it has always been pretended that emissions are an externality and someone else’s problem. They’re not. And in this case Scope 3 emissions are Sainsbury’s concern. Their claim that they will be net-zero carbon is not true unless they take them into account.
This is sustainable cost accounting again.
Scope 3 is emissions from things people sell. So, Sainsbury’s sells me petrol, Sainsbury’s is on the hook for the emissions I make.
And don’t forget, everyone should be bankrupt if they can’t go net zero.
A potato cannot be net zero. I eat it, I convert the contained energy into the ability to inhale oxygen and exhale CO2. I don’t eat it, it rots, there could be, anaerobic style, methane emissions. Non-anaerobic, CO2. Or it’s eaten by the mice who do the exhale thing.
If all are responsible for their Scope 3 emissions then it is impossible to sell a tuber.
Unless, of course, you’re a Tuber selling yourself for a grant cheque.
