Following the lead of Australia, the EU is planning to outlaw the use of old-style filament light bulbs as early as 2008. On the surface, this edict to adopt low energy fluorescent devices looks a great way to reduce energy consumption worldwide. Some analysts claim a saving of 10% energy worldwide if this were adopted by the whole planet which is likely to save much more CO2 than any green generation schemes in a much smaller timescale.
However, my training as a chemical engineer tells me to look at the full environmental life cycle of any new product. Any fluorescent light uses mercury to produce the light as high voltage is applied to vaporise and excite the mercury atoms.
Mercury is particularly bad for the environment because it does not get destroyed and can cause catastrophic effects for the food chain, for example see this article.
Traditional filament bulbs use no mercury - so should we stop this inexorable move towards compact fluorescent bulbs (CFL's)?
In short, no, because the story isn't quite that simple. Ironically, the majority of mercury released into the atmosphere actually comes from burning fossil fuels. A US study found that a filament light bulb actually released over double the mercury into the atmosphere that a CFL did due to this indirect effect. The argument may be more marginal for countries such as France, where a high percentage of power is generated from nuclear.
Another welcome development is that some manufacturers, such as Phillips, are working the reduce the mercury content of the lamps they are producing.
The other thing to remember when you change your CFL after many years of saving the environment is not to toss it into the environment - CFL's are one of the many products subject to the EU's WEEE recycling scheme - the manufacturers are obliged to recycle the products.
Convinced now? If not, see this great video - short and well to the point.....

With the blog race now behind us, the taste of champagne still on our lips, I can't help but ponder the greatest sustainability issues facing England this year. If fact one is unfolding in front of our eyes right now:
Can England sustain the form that made the Aussie's cry just a few weeks ago? A shaky start, but optimism is high as Anderson rips through the Kiwi top order.... The England cricket fan, a helpless victim of Variable ratio reward, is kept on the edge every game. Think of the glory, beer will flow, ugly blokes will get lucky, plasma screens saved from pelting beer cans.
Come on boys, make us proud!
Still to come, can England sustain the ultimate glory, the World Cup of Rugby Crown.

We have all heard of fair trade in our local supermarkets, if you haven't here is a quick intro...
The FAIRTRADE Mark is an independent consumer label which appears on products as an independent guarantee that disadvantaged producers in the developing world are getting a better deal. As always, Wikipedia hits the nail right on the head
So why buy these products? Lets take a look.
The story of Toledo Cocao Growers Association (TCGA) is a perfect example of how much Fair Trade makes a difference. The cooperative has about 126 members and is located in the Toledo region of Belize, which is the poorest in district in the country.
The Beginnings of TCGA The cooperative was formed in 1986 in order to yield higher prices, improve living conditions, and help farmers increase the quality of their cocoa. TCGA's cocoa is grown organically and under a canopy of shade trees including valuable timbers of mahogany, cedar and teak. Farmers also use sustainable methods such as composting and typically grow a diversity of other food crops among their cocoa. Organic production keeps the river water pesticide-free. The preserved shade canopy makes the area a good carbon sink and supports a wide variety of natural species, including at least 187 kinds of birds.
Until the early 1990s TCGA's farmers earned enough from their cocoa to buy clothes, basic necessities and a variety of foods. However, the price of cocoa was suddenly cut in half between 1992 and 1993, falling below the cost of production.
Fortunately, a chocolate company from the United Kingdom called Green and Black's offered a long-term contract for a stable supply of quality cocoa. They agreed to buy all the cocoa TCGA could produce at an above-market price. The cocoa was used to create Maya Gold Chocolate, which was introduced in March 1994 bearing the Fairtrade Mark, denoting Fair Trade certification in the UK. The long-term contracts Fair Trade offers have given the farmers the confidence to make long term plans to improve their production. Many who had abandoned their crops have now returned to their home communities to resume their traditional, sustainable lifestyles.
That was the first product in the UK to bear the mark, there are now 2000 but still the sales represent only 0.5-5% in their product catagories.
Take a look the latest newsletter , or better still, put a product in your trolley and feel good!

When we first started this blog site it was to look at two aspects:
- Would we be able, as complete novices, to put together and run a blog that would gather enough readership? and, more importantly,
- To highlight the growing impact of the issue of sustainability in everyday life.
In the early days it was the likes of Friends of the Earth and others that brought the issues of the planet to the fore however this area has grown to become more and more main stream as it jumped over the chasm and into the main stream with the likes of the Fortune sustainability rankings. Nowadays it would seem unforgivable for a company to put out their Annual Report without the use of the word sustainable in their CSR section if nowhere else.
I would argue it has now become unacceptable for companies not to at least point their investors at some of their sustainability projects/ developments. But in the cynical world in which we live one can certainly feel that some of the major corporations that publish their green credentials set themselves up when the reality does not match their marketing. If you are going to advertise yourself as green then one bad news story that runs contra to that message can ruin the thousands of dollars spent on image. A most recent example was BP; having gone through a significant greening campaign over the past years the oil spill in Alaska and the subsequent inquiries have undoubtedly gone along way to undo all the past CSR work.
So what does the corporate world do? Do we almost need a root and branch check of our processes and systems along the lines of a "Sarbanes-Oxley" for sustainability - help no! Companies that are in business for the long term have a reason to act in a sustainable way. We need to help the others to come to this conclusion through legislation and our own buying habits.

These are strange times in which we live. Ray Stubbs, a former credible sports presenter, is singing karaoke in front of millions on Fame Academy. At the same time, David Cameron, the leader of the conservative party in the UK, is trying to get back into power by running counter to usual Tory philosophy and arguing for HIGHER taxes on airline fuel. In both cases, there seems a smack of desperation by trying to persuade an increasingly fickle public to vote for their particular approach. The fundamental problem with the conservatives' ideas is their complexity - each passenger will be allowed one short haul flight per year without the higher tax as well as an VAT exemption for business travel - but the bureaucracy required to manage the scheme will allow loopholes and dodges for the usual beneficiaries of such schemes (i.e. those with the money to outmanoeuvre the rules).
In fairness to the Tories, personal flight allowances are but one of several options being considered. But they should be taking their traditional stance and rather than meddling, should be looking to market based solutions such as carbon trading. This is one area where the Prime Minister elect, Gordon Brown, actually has stealt a march by publicising the idea of a World Carbon Trading market being based in London.

Keeping up with Jones has been a quite typical past time in many countries - not only in the UK! However could we be about to see this extended in to monitoring of carbon footprints in the future? In the past an outward sign of "we're doing well" would be the number of cars parked on the drive and the size of their engines - this could well be reversed with the neighbour hiding his gas guzzling engine away in the garage rather than proudly polishing it on the drive at the weekend... In the winter time look to your neighbour's roof - if the snow's still sitting there then they have insulation if it comes off then obviously then do not... you can just imagine where this new one up man ship could go... "How much recycling do you do?" brings Neighbourhood Watch in to a whole new ball game! And think about those annual Xmas light competitions - will the behaviour picture about be acceptable?
Or is this all a fashion statement with the icons if the media tootling around in their Prius cars? My feeling is it is here to stay... In Italy the idea has caught on as households publish how good their energy efficiency rating was for their property .. with the home buyer's pack requirement coming in in the UK the need for the seller of the property to announce this in the future to all prospective buyers begins to give the householder a reason, other than "mere energy saving", to think about investing in insulation and other energy saving devices. In the past the owners may have thought they would not recoup their investment before they potentially move along the housing ladder this in the future means a quicker sale or better price.
No doubt when this does become the next big craze rather than just the minority investing in wind turbines and such like then we will all grumbling and moaning eventually catch up and maybe, just maybe, it will all become acceptable behaviour to think about energy usage or carbon footprint size as we decide our future actions.
