In a bid to offset the carbon emissions generated by her jet set lifestyle, the Queen is said to be sending £3 million worth of our taxes abroad for use in eco friendly projects - including the production of power using pig waste in Thailand. Er-hem. Much as my somewhat anarchic sensibilities mean that my head is literally filled with cheap cracks at this precise moment in time, I shall resist the urge to publish any of them.

As Eurostar moves its HQ from Waterloo to St. Pancras, and shaves off 20 minutes' journey time to the continent, another milestone is being somewhat overlooked: it's about to complete its first ever carbon neutral journey.

The greenest Eurostar trip yet will leave London for Paris on at 11.03 on Wednesday November 14th. All journey on Eurostar from then on will be carbon neutral, at no extra cost to passengers.

Stagecoach has decided to power its Scottish buses and coaches with chip fat - hot on the heels of McDonalds doing exactly the same thing with its delivery vehicles. It sounds like a strange choice for a fuel, but used chip fat makes a good biofuel because it doesn't present the same problems regarding destruction of natural habitats or interference with the food chain which other biofuels do.

I have to admit to the fact that Stagecoach, like McDonalds, is not one of my favourite companies - if you remember the scandal involving Brian Souter donating £1m to the Scottish Schools Boards Association in order to campaign to keep Section 28 in place, you'll know why. However, while I have reservations about Stagecoach as a company after Souter's actions, I have to admit that this latest initiative is a good idea.

Planning to move house? It seems that Bradford is the place to go for the green minded individual. The city was revealed to have the lowest environmental impact of any British city, in spite of its undeniably large role in the Industrial Revolution. Contrary to popular belief, Bradford's rivers were not polluted beyond redemption during this period in its history, and the streams surrounding the city are now a veritable haven of wildlife! Bradford also boasts large areas of green space, and has a number of successful recycling schemes in place. You can read more about Bradford's environmental initiatives - from their 'real nappy' scheme to the Forest of Bradford project, which aims to extend areas of woodland in Bradford - at the Bradford Environmental Action Trust.

Liverpool was voted the least sustainable place to live, with poor water quality and a lack of evidence that it is working towards a more sustainable future dragging it to the bottom of the list.

The survey of cities was carried out by charity Forum for the Future.

British Telecom today unveiled plans to meet a quarter of its electricity needs using wind turbines by the year 2016. BT already reduced its carbon emissions by 60 per cent between 1996 and 2006, and it is estimated that the use of turbines will cut BT's C02 emissions by a further 500,000 tonnes. The project is set to be the largest corporate wind power initiative outside the energy sector. The cost of the project will be in the region of £250 million.

BT has applied for planning permission to build test masts at Goonhilly Satellite Earth Station in Cornwall, Wideford Hill Radio Station in Orkney and Scousburgh Radio Station in Shetland. It is hoped that 100MW of energy will already be being produced by turbines by 2012.

Despite the fact that it is a signatory of the 1959 Antarctic treaty, which stipulates that no new claims shall be made over any land in the Arctic, the Foreign Office has revealed that Britain has made plans to extend its rights to oil, gas and mineral exploitation up to 350 miles offshore into the Southern ocean. A good proportion of the resources which Britain plans to extract from the Antarctic are yet to reach levels shallow enough for them to be mined, but fears nevertheless abound regarding the possibly detrimental impact which Britain's proposed move will have on the environment.

This proposal comes at the same time as WWF are calling for areas of the Antarctic to be turned into marine reserves in order to protect endangered species.

If you're finding your daily grind unsatisfying, and you long to get up every morning with saving the world on your mind as well as paying the bills, then this guide could well provide you with some food for thought. 'The Ethical Careers Guide' offers a range of advice on different careers, as well as fascinating case studies of people in positions ranging from a Campaigns Officer in a charity to a social worker working for a local council.

I was given a copy of this book by a friend after I left university. I'd decided my next step was to find some voluntary work - with the eventual aim of doing some paid work for a charity - and I definitely found the book useful in terms of inspiring me in my quest. In particular, I think the fact that it includes a large number of case studies makes things sound a little less daunting, as the case studies make you feel as if you're having an informal chat with someone rather than reading a 'guide' per se.

In what is believed to be the first move of this kind taken by a local council, St Albans City and District council have transformed a 1950s semi-detached house into an ecohome and opened it to visitors. The house's impressive range of energy-saving features includes a 1 kw wind turbine, solar thermal roof panels and a 4,700-litre rainwater-recycling tank.

The project has been awarded the Green Apple award for Environmental Best Practise by The Green Organisation. The Green Organisation is an independent company which seeks to recognise and confirm environmentally-aware practices in business and government. They state their aim as being to provide a service which operates not as an 'environmental watchdog' scheme, as so many other organisations do, but rather as a more positively focused, reward scheme system.

The contractor, Borras, also won a Considerate Constructor award for its successful use of so many recycled demolition materials in the creation of the house.

The government has pledged to almost completely eradicate the use of conventional light bulbs by 2012, with the phasing out process beginning in earnest next year. The move, which was announced at the end of last month by environment minister Hilary Benn, is said to have the potential to reduce greenhouse gas emissions by more than six million tonnes a year.

The government is also at pains to stress that, despite that fact that energy-saving light bulbs cost more to buy than their non-energy-saving counterparts, their use will ultimately save homeowners money, as they last up to 12 times as long as normal light bulbs and use nearly 80% less electricity. Just replacing one conventional light bulb with an energy-saving equivalent could save a household £7 a year.

If you've got plans to redecorate your house, but don't want to alter the world, or your own lungs, in the process, then Ecos Organic Paints might be the answer. Most paints currently on the market are laced with nasty substances like formaldehyde and lead. Ecos produces the only range of guaranteed non-toxic paints in the world, for people who don't want to contribute to global warming or risk their health just for the sake of changing the colour of their walls. Ecos paints don't contain of the any animal products like bone or tallow fatty alcohol which are often found in other paints, either, so you can rest assured you're making a completely ethical choice when you buy them.

You can order a brochure or buy paint through the Ecos Organic Paints website.

Professor Chris Ripley, new director of the Science Museum, has revealed plans for a £6 million exhibit showing people exactly how global warming has already affected the planet, and what implications it could hold for the future. Ripley is at pains to stress that the purpose of the exhibition is not to promote a particular course of action, but to allow people to "come to their own conclusions" about which policies should be put in place in response to global warming.

The exhibition is not due to open until 2009, but, in the meantime, a small trial run exhibition opens next week in the Science museum's Wellcome wing, focussing in particular on the role of biofuels in cutting levels of carbon emission.

A list of countries which ranks their relative environmental impacts, from most environmentally friendly to least, has just been released. The list was created by US environmental economist Matthew Kahn, using the United Nations' 2006 Human Development Index and the 2005 Environmental Sustainability Index. Factors taken into consideration included renewable energy use, greenhouse gas emissions and conservation efforts. General quality of life was also looked at, with things like levels of education, employment and health swaying final results as well as environmental concerns.

According to the list, Finland is the most environmentally friendly country. Ethiopia was judged to be the least environmentally friendly. In general, Scandinavian countries came out on top, and countries in Asia featured nearer the bottom of the list.

In a bid to shake its image as an evil, money-grabbing multinational, and show that it cares, the world's largest retailer, Walmart, has launched a campaign to become a more environmentally friendly company. Plans are in place to improve waste reduction and energy efficiency measures across all its stores, factories and transportation vehicles. It has even launched a website, Walmart Green, where it showcases the energy efficient appliances, recycled furniture and organic cotton clothes and bedding that it now sells.

Critics are saying, however, that simply going green is not enough to win Walmart the status of an ethical company, and that they are using it as a diversion tactic to draw attention away from the fact that they refuse to improve conditions and wages for their workers.
