people pollute more than vans

September 16th, 2009 § 3 comments

Ocado, online grocery home delivery service, claim on their vans that they are ‘as green as walking to the supermarket’ and on their website has the statement

With such a lean, efficient operation, we’ve been able to lower our carbon emissions to the point where each Ocado delivery now has a lower carbon footprint (CO2 per £ of sales) than walking to a supermarket.

I’m buggered if I think how driving a van can produce less CO2 than walking, especially as at the moment they are using biodiesel and not something like hydrogen fuel cells which produce only water (not counting all the CO2 produced in the ‘manufacture’ of the hydrogen). I wouldn’t have given it much thought if the claim had been nearly as little as walking, but less…?

So I sent them an email…

To: ocado@ocado.com
from: Sim-O
Subject: your CO2 output

Sri or Madam,

On your vans you claim…

We’re as green as walking to the supermarket

and your website also carries the statement…

With such a lean, efficient operation, we’ve been able to lower our carbon emissions to the point where each Ocado delivery now has a lower carbon footprint (CO2 per £ of sales) than walking to a supermarket.

Could you substantiate that claim, please. It is a big claim and it has to be true otherwise you would not be able to make it, but I am puzzled as to how.

What are you counting as producing CO2 in each type of journey? How far back through the delivery chain are you going? What, exactly, are you comparing for each type of journey?

What are the figures and the maths that enable you to make such a claim?

Kind Regards

I’m not trying make a point, get some info so I can point my finger and yell ‘Cpaitalist Charlatan Pigs!’, but genuinely puzzled. Just by the fact that the van has a driver puts the van on an equal footing with the pedestrian. Doesn’t it?
