I love my Landrover Discovery. I’ve had a Landrover of some sort for around 20 years now - from an ex-military Series III Lightweight, through a ‘79 Range Rover which is in a pile of bits waiting for time, enthusiasm and budget to ‘have some fun with’, and a ‘64 Series II.

My daily commute is almost a pleasure in my 4wd armchair, and on occasions I get to pull tree roots out, tow stranded vehicles, or pull loads of hay around.

But I’m being made to feel increasingly guilty because of my excessive carbon footprint.

Now I’m quite good the rest of the time - I very rarely go on holiday so no frequent flyer miles for me. We’re very good at recycling, and try to keep our energy use under control.

Discos on the whole aren’t as bad as they’re cracked up to be - mine has a 2.5 litre turbocharged diesel engine, and on average I get around 550 miles out of a 70 litre tank full. If I had a 4.2 litre v8 supercharged Range Rover Sport (as much as I would dream of one) or a Tuareg, or those silly Porsche things.

I’m not saying the rest of my life is perfectly eco-friendly, but I don’t think it’s too bad. Aren’t I allowed a little luxury?
