Let’s get things straight from the start – gas-powered vans aren’t supposed to be saviours of the planet or even a panacea for all fleet ills.

Indeed, the vast majority of van fleet operators won’t be interested in them as most need to travel more than 300 miles in a day without returning to base.

But if short haul stuff is your game and you seriously want to be environmentally friendly, there’s no doubting the credentials of the two vehicles on test here.

The money-saving aspect is, of course, the icing on the cake.

What could be greener than taking waste gas from a landfill site that would otherwise just disappear into the blue yonder and use it to fuel commercial vehicles – which in the case of Camden Council were collecting waste for landfill sites anyway.

The C02 emissions reductions of 62% over diesel are staggering – in fact the gas-powered Daily already conforms to Euro VI standards – and most van manufacturers haven’t even reached Euro V yet.

Don’t run away with the idea that natural gas power is something new.

The Europeans have been using it for years with no problems and in fact Iveco has a history of producing such vehicles, so we can assume that any of the old problems (such as fuel quality) will have been ironed out by now.

Current European sales are running at around 1,000 per year, mostly in Italy and Spain.

The full range of Daily will be available with gas power – trucks, panel vans and tippers from 2.8 tonnes to 6.5 tonnes, although only one engine power is on offer – 3.0-litre with 136bhp and 258lb-ft of torque.

There are 28 different models on offer altogether.
