I LOVE the smell of petrol and hypocrisy in the morning.

As a fan of the fast-moving circus that is Formula One, I’m used to people pointing out that there’s nothing exciting about some over-paid guys driving round in circles for two hours.

I’ve also become accustomed to being preached at about all that flying around the world and petrol-guzzling engines being terrible environmentally. Shame on me for supporting it, etc.

One of F1’s biggest stars, Lewis Hamilton, has certainly made my life a little harder when one of those conversations kicks off next. He’s told the BBC in an interview that he’s going to adopt a vegan diet, for health reasons and because he’s worried about emissions - from cows.

When he points out that pollution from the back end of our bovine chums is “more than what we produce with our flights and cars”, he’s actually pretty much bang on. Our love of beefy stuff does mean that we’re massively polluting the planet while we enjoy our burgers.

If I said it, you’d probably just ignore me. But Lewis’s chosen profession involves flying around the world all year, supported by hundreds of people, and driving a high-powered car around a track with 19 other guys for sport/entertainment.

Not only that, but he travels a lot by private jet, and regularly nips off between races to other parts of the world for a few days. He must do very well out of Air Miles.

His lavish lifestyle sees him wearing cool leather jackets, performing “burn-outs” on motorbikes and a thrilling range of other activities that aren’t exactly helping to prevent polar bears from trying to balance on ice cubes.

Dog ownership also contributes negatively to saving the planet. All that dog food for his four-legged friend, Roscoe, has to be made somewhere, from meat, from animals that ate crops and did a fair bit of letting off wind before winding up in a tin.

Car manufacturers provide their engines to, and participate in, Formula One because it allows them to fast-track the development of technology that will be on your car not long afterwards - because we all want greater efficiency and that warm glow of knowing we did our bit to help the planet by buying a "green" car. The current energy recovery systems in F1 cars are improving the efficiency of hybrid engines in cars hitting the roads now, but let’s not kid ourselves.

Each driver gets through many sets of tyres per race weekend alone. The pace of development means new parts are produced at an incredible rate. F1 might be trying to do things that lessen its impact, but it’s a long way from environmentally friendly.

What we really need is a multi-millionaire sports star to suggest that his intention to go vegan might encourage others to do so, thus helping the environment.

You’re quick in a car, mate. Apparently you’re not so speedy when it comes to spotting irony.
