Green Options

A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.

As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

London Mayor Boris Johnson has announced plans to create Britain’s first “hydrogen highway” by building a network of hydrogen filling stations throughout the capital.

As part of the scheme, a pilot fleet of around 150 hydrogen cars, five buses and 20 black taxis will be assembled in the run-up to the 2012 London Olympics.

The flamboyant mayor has gone on record as saying that he wants Britain to become a world leader in fuel cell technology and his team have made the ambitious claim that, within twenty years, up to one in three of the 31m cars in Britain could be fuelled by hydrogen.

On the same day that a loophole in endangered species trade law was closed, officers from the Metropolitan Police Wildlife Crime and Chinatown Units raided a TCM shop.

Approximately 200 products made from endangered tiger, leopard, and musk deer were seized from a “traditional Asian medicine” shop in London’s Chinatown area - a productive raid on the first day that an amended wildlife trade law came into effect.

London’s mayor announced a new 2 million tree plan to help fight climate change and keep Londoners cool.

The plan is designed to counteract the “urban heat island effect” in which urban areas absorb and release more heat than surrounding areas, due to having more pavement, traffic and power demand.

A new organization, starting off in South London, but open to working in other areas as well, is making links in the green world on the grassroots level and is getting some serious attention.

A new series of wildlife-rich ponds and marshlands will attract frogs, toads, water voles, great crested newts and dragonflies to London’s city center.

The habitat will be found in Paddington Recreation Ground, and it will be made readily accessible to the public via a network of decking pathways and a wooden “dipping” platform to allow school children to take part in pond-dipping and to learn about the variety of animals that live in the water.

Last year, 300 folks across North America turned in their car keys for a month as part of the 2008 Zipcar Low-Car Diet. And, in addition to cutting congestion, they also walked 85% more, biked 136% more and decreased their miles driven by 71%. Pretty impressive, eh? Starting July 15, a new crop of participants from all Zipcar cities worldwide* will begin the 2009 Low-Car Diet: one full month of living [...]

Earlier this week, London launched Britain’s first ever electric car hire scheme.  The initiative, run by Streetcar, the country’s largest pay-as-you-go car-sharing club, will offer members a specially adapted Toyota Prius at rates starting from £5.95 (just under $10) an hour.

If the trial proves a hit with club members, Streetcar plans to roll out extra electric cars throughout the capital to meet rising demand.

A new hydrogen-powered car, whose designs will be “open source” and posted for free use on the web, was unveiled today in London. The company behind the Riversimple urban car claim the new model proves hydrogen automotive technology is ready for roll-out now rather than in 10 years’ time.

The open-source approach means entrepreneurs around the world could download the designs and manufacture the two-seater prototype locally for free.

The car, which drove in to the launch event, is capable of a 50mph top speed, 0-30mph acceleration in 5.5 seconds, and has a 240 mile range. The car’s backers say it has greenhouse gas emissions of 30g/km CO2, less than a third of the latest hybrid petrol cars such as the Toyota Prius and Honda Insight.

The lightweight Smart car-size vehicle uses hydrogen in a modest 6kW fuel cell, and – in the case of this prototype – uses hydrogen converted from natural gas. Hydrogen can also be created from water using electrolysis and potentially even from bio-fuels.

Fuel cell technology is a pollution-free electricity generation technology that is expected to compete with traditional methods of creating and distributing electricity. Fuel cells can be likened to a continuously fuelled battery that operates by using the chemical properties of hydrogen and oxygen to create useable electric current.
