We love coming across projects that when you first hear what they are all about you say, 'surely that can't be done'. This is exactly what we thought when we heard about Izhar Gafni's Cardboard Bicycle Project.

Drawing inspiration from a cardboard canoe (yeah we're with you: HOW DOES THAT WORK?? Cardboard + water = disaster right?), Izhar made a cardboard bike from scratch using origami techniques. It is capable of sustaining up to 485 pounds, that's over 200 kilos!

And the best thing: it only cost about $9 or £5.50 to make!!

Take a look at the making of in this video:

Everyone knows that getting on your bike is a great way to reduce CO2 emissions while keeping fit. Why not go the extra mile and make your cycling as green as possible.

As a kid, one of my favourite ways to wind up my Dad was throwing his ornamental pine cones on to our open fire in the winter. Not to be mean: I just couldn't resist it. I loved the way the (carefully collected and long-cherished) giant cones lit up so quickly and burnt with a brilliant blue flame, created by the salt in the sea air they'd absorbed as they grew.

So I was filled with childish, pyro glee when I found that you could now buy pine cones specially made and prepared for burning, along with other naturally fire-attracting and fragrant forms such as bay leaves, dried lemons and chillis. Designed to be used on barbeques and bonfires, natural herb barbeque lighters are a charming alternative to chemically laden fire-lighters and are scented with herbs and thyme oil. These are a damn site better for the environment and smell delicious too. Hand-made in Dorset, they're £14.50 for a pack of 12 at the Green Rewards Shop.

Ting, the small London label behind those funky bags, belts and wallets made from upcycled materials, has really shown what its designers can do with this full-sized hammock made from car seatbelts.

The belts in the 'ting sling' are woven together and available in a choice of bright shades including hot pink, orange, camel, turquoise, chocolate or black. You'll have to contact the makers to find out how to get your hands on one, but what an awesome alternative to the traditional hammock!

Bicycle baskets are a must-have for the modern day eco-worrier, and are even better when they're designed to detach and double up as shopping bags like this pretty pannier by designer Marie Louise Gustafsson.

The inspiration for the basket's unusual design comes from Gustafsson's Swedish grandmother's crocheted tablecloths. True granny chic!

How does the idea of staying in a cozy, pre-erected, eco-friendly tent for this summer's festivals grab you? As someone who loves music but has a phobia of mud, it's certainly sounding like the way forward to me, so I checked out Tangerine Fields' site to find out the deal with their festival accommodation.

I was pleasantly surprised at the prices, which start at around £47 per person for a tent-only deal. A step up are the special packages, which include such luxuries as a seperate area within the main festival campsite, with toilets and hot showers exclusively for Tangerine Fields customers -- these start at around £70 per person, so for a modest £30 extra you can lord it over all the poor old sods in the normal tents, having to queue for the chemical bogs.

If you're chosing to spend your holiday in the UK you're already off to a good start in the green stakes, and if you choose accommodation with sound eco credentials, you'll lesser the impact of your trip even further.

The Green Tourism site is a great first port of call if you're looking for an eco friendly B&B or hotel in the UK, and has a handy online list of establishments that have been approved by the scheme. And this weekend, I had the chance to visit one hotel that's doing its bit for the environment, Three Acres Country House, which is set in the beautiful, remote surroundings of Exmoor National Park.

Nothing is more evocative of summer than the smell of sizzling barbeque food (even if you happen to be veggie). But how green is this form of outdoor cooking? The answer is it can be either decidedly ungreen, or not bad at all depending on which methods and fuel types you choose...

Lucy Sigel has given some good tips in this article on how to reduce the impact of your barbeque; the main point being that you should avoid the modern sort that pump out vast quantities of gas or electricity and ensure you use sustainable charcoal. A traditional, charcoal-burning model is the greener choice, and I love the fact that she mentions the best barbeque she ever had was cooked on a customised wheelbarrow.

You can always trust Firebox to come up with groovy gadgets to capture the imagination, and its range of solar powered toys is growing all the time.

Just in time for summer are these funky, Chinese-style LED lanterns, which soak up the sun during the day and give off a gorgeous glow as night descends. Each lantern is equppied with a dusk sensor so you need do nothing more than hang them in an eyecatching position and wait for the evening to begin. Each pack contains three red lanterns and three white ones. But here's the clever bit: the white lanterns contain colour changing LEDS that gently cycle through a kaleidoscope of entrancing colours. Trippy! £29.95 at Firebox

It won't be long before we're all reaching for our beach tennis bats and baguettes, as parks and green spaces everwhere prepare for an onslaught of litter and discarded food...

Firebox has come to their aid, with this fabulous, totally biodegradable picnic kit that will leave minimum impact on the environment if you accidentally drop a knife while diving into the brie. The crockery in the set is made from our old friend cassava (the tapioca plant), with wooden spoons, forks and knives. You can even choose a gingham or camouflage cloth to complete your al fresco dining experience. All for just £14.95

A year ago, the idea of a cardboard tent seemed like a highly unlikely, if not undesirable prospect for your temporary festival home. But following a successful trial, the Myhab is about to make its debut on the festival circuit.

Compared with pitching up your own tent, choosing a Myhab is in many ways a luxury option. They come pre-erected at various festival sites, including Reading, Leeds, Latitude, T in the Park and End of the Road festivals, and are fully waterproof, made from ultra tough recycled plastic and water proof cardboard.

I have to admit I was a bit flummoxed when I saw this claim being made. Barbeques? Butterflies? Perhaps it's to do with making sure you don't singe their tiny wings as you cook your Linda McCartney bangers al-fresco style.

But no: what's important here is not where you place your barbie, but the charcoal you use on it. It turns out that a lot of the charcoal we burn in the UK comes from abroad, and this is bad for the environment in a nuber of ways. First, there's the carbon cost of transporting the stuff. But less obviously, choosing instead to use homegrown charcoal can also be beneficial to wildlife, as it's sourced from woods that are managed to provide habitat for butterflies and birds.

Enjoy a 'picnic with a conscience' with this ecofabulous outdoor dining set that helps you reduce your impact on whatever beauty spot you choose to spread you mat on.

The set contains fully biodegradable and compostable plates, cups, glasses, cutlery and napkins, all kept together in a cute, jute bag you can also use for shopping. Every part of the set comes from sustainable plant sources and is ethically produced Choose between a 4-person and 8-person set.

From £16.99 at Nigel's Eco Store

Literally, that is! If you're brave enough to set up camp somewhere so remote that showering the conventional way isn't an option, then this little pouch will provide you with the relative luxury of a hot wash, using the suns rays to warm the water.

Simply fill the pouch with water (it takes a generous 20 litres), leave it in a sunny spot and give it three hours to warm. Once it's ready, the solar shower will let you freshen up in comfort. £8.99 at Ethical Superstore.

Into extreme sports? Unfortunately, with the demand for new products, urge to travel to new spots, and need to keep wind, rain, snow and waterproof, surfers, snowboarders and skaters have to admit they've got a pretty high carbon footprint.

But admitting exactly what each of us, as individuals, contribute is the vital first step; Patagonia, already known as a pioneering eco friendly company, started by a passionate surfer, is leading the way with it's latest project - The Footprint Chronicles.
