If you are reading this, the chances are you're either cool yourself or at least involved in some cutting edge activity worthy of that accolade.

That would be the verdict of Cate Trotter, an entrepreneur with a background in eco design and CSR who has set up a tour of London's green hotpsots for those wishing to sample the capitals sustainable delights.

Ms Trotter, who describes herself on promotional material as a 'cool hunter', has launched the tours under the aegis of her company Insider London in an effort to show that being green is hip - and that the capital is on the crest of the wave when it comes to innovation and inventiveness.

The eclectic tour of the city centre takes in a smattering of landmark sustainable buildings - showing off green roofs and a variety of architectural practices making the structures more efficient in terms of energy use and waste production.

It also takes a look at green corporate strategies and examines what's going on in the board rooms of big business and its spin off companies.

Take Andaz, for example, a green hotel which is owned by a splinter of the Hyatt group, an uber-ethical outpost of the Timberland empire and the efforts of a son of the Clarks footwear dynasty who is making some of the greenest shoes on the planet.

The tour also looks at some at how smaller companies build on the principles of sustainability, often the product of their owners' passion for the environment and a certain way of life, are thriving in London.

Among these is Rootmaster, a vegan restaurant in a double decker bus, Junky Clothing, a kind of Frankenstein's clothes shop which hacks up unwanted outfits and sews them back together into quirky hybrid outfits.

Add to this food shops which take concerns about food miles, fair trade and organic produce to a charming extreme and you've got a pretty mixed bag of a tour.

According to Ms Trotter, the tour is aimed at environmental professionals 'in weekend mode' as well as anyone who's curious about how the environmental agenda is shaping our capital from the grassroots up.

It manages to be professional and relaxed at the same time, and likely to surprise even the most knowledgeable London greenies.
