London is now announcing that it plans “to create a new network of quick, simple, and safe routes for cyclists and pedestrians that represents the largest investment in walking and cycling in the city’s history.”

This is not some token initiative, either. London is committed to spending US$975 million over the next ten years to implement five new programs “with the aim of having one in ten round trips in London each day made by bike, and saving some 1.6 million tonnes of CO2 per year .”

The photo above of the bike ambulance makes me super-happy!

Drivers now have to display a coloured sticker on their vehicle to enter the inner city zones. The colour depends on the pollutants the vehicle emits.

The cities are gradually phasing in fines of 40 euros (£29;$58) for anyone caught driving without a sticker.

Other German cities – but not all – plan to have such zones later in 2008.

The stickers – green, red or yellow – are mandatory not only for locals but also for foreign drivers, including tourists.

There is a one-off charge of five to 10 euros for the stickers, issued by Germany’s vehicle registration authority and authorised garages.

Bike couriers in Cambridge, UK have been given tricked-out cellphones that monitor the air pollution around them and ten report that information to a research team. What a clever way to gather this information.

The technique is made possible by small wireless pollution sensors and custom software that allows the phones to report levels of air pollutants wherever they happen to be around town.

“Mobiles are everywhere, and now have a lot of computing power,” says Eiman Kanjo, the computer scientist at Cambridge University, UK, leading technical development of the project. “They can provide an alternative to expensive custom hardware and report from places that otherwise aren’t monitored.”

Kanjo and colleagues gave local cycle couriers air-pollution sensors and GPS units that connect to their cellphones via Bluetooth. Custom software lets the phone constantly report the current air quality and location to servers back in the lab.

“They cycle around the city as usual and we receive the data over the cellphone network,” says Kanjo. “We can find out what pollutants people are exposed to and where.”

Can this invention get any better?

We’ve managed to develop a way to successfully capture a majority of the emissions from the dirtiest motor we could find,” Palmer, who has consulted for organizations including the World Health Organisation and GlaxoSmithKline, told Reuters

By cycling instead of driving or taking public transport, you are doing your part to keep the air clean. The problem is that you have to cycle through all the pollution created by people who aren’t making any effort.

The Spacing Wire has information on what Canadians can do to get the federal government to support cycling.

Under the Climate Change Bill, carbon dioxide emissions must be cut by at least 60 percent by 2050. It also sets a legally-binding interim target for carbon cuts of 26 to 32 percent by 2020. Failure to meet targets could land the government in court says environment minister David Milliband who is behind the draft.

Previously, we looked at an artistic display of this concrete.

“Visitors to the Italian Pavilion of the architecture exhibition in the Venice Biennale, which will remain open until Nov. 19, will get a breath of fresh air. That’s because parts of the concrete walls and grounds have been built with cement containing an active agent that, in presence of light, breaks air pollutants such as carbon monoxide, nitrogen oxide, benzene, and others through a natural chemical process called photocatalysis.”
