The Green Party has published its ten point cycling plan for Dublin. Among the key points are:

Writing on the BBC Website, Mark Mardell profiles Freiburg, perhaps the world's greenest city. Mardell writes:

What is missing is the constant low thrum of traffic in the background. It's not that cars are completely banned from the city, but most of the centre, rather than the odd street, is a pedestrian zone. You pedal or walk to trams or trains. Freiburg can lay claim to being the greenest city in the world, and it's all rather pleasant.

Interesting news from Toronto, where plans by mayor David Miller to make green roofs mandatory in the city are being criticised by both the construction industry and green roof advocates.

Via Treehugger, architect Cameron Sinclair writes in the Huffington Post :

For the past twenty years the voice of the architecture profession has mainly been drowned out by the computer generated sky-piercing towers of luxury. Year after year the biggest names in architecture tried to out do each other in what is technically feasible...This constant craving to create jewels of desire in the urban fabric left the general public wondering what on earth we do. Now, with the global economy in tailspin, these exercises in object making have come to a crashing halt. For many of us, we couldn't be more thankful...For those of us that work in this arena we are being swamped with requests for help from the camps in the eastern Congo to the hoovervilles in southern California. The desire for well built, sustainable structures is immense and young professionals seeking meaning are finding themselves drawn to providing their expertise to these communities. There is immense opportunity for architects to work in the service of humanity rather awkwardly trying to define it or worse impose a solution on it.

The Japanese government is to spend 15 trillion yen (£100bn, or as I prefer to write it to really let it sink in, £102,000,000,000) on an economic stimulus package focused on green technologies such as electric cars, solar panels and energy saving building materials, according to an article

TreeHugger has posted an interesting slideshow on the best in green design and architecture, including Edouard Francois & Duncan Lewis designed French holidays homes (below) that are designed to fit seemlessly into the surrounding environment, and the green roof on the California Academy of Sciences (bottom).

A quick look through the summary of today's budget measures at budget.gov.ie reveals the following under the list of capital expenditure measures:

An interesting discussion on TreeHugger on the merits of various forestry certification programs, including the below photo (courtesy of Heart of Green) that apparently shows both FSC (Forestry Stewarship Council) and SFI (Sustainable Forestry Initiative) certified forests.

A new report from the UK's Green Building Council has recommended a variety of steps that builders, planners and architects can take to enhance biodiversity in the built environment. Among the recommended design features are:

- Nesting bricks built into cavity walls for birds such as swifts and starlings
- Ledges on high buildings that mimic cliff faces for peregrine falcons and other birds of prey
- Careful lighting and roosting boxes under bridges to allow bats to inhabit areas that are usually too bright
- Green roof and walls (explored at length in Construct Ireland last year)

A quick glance through the ideas short-listed in the UK Sustainable Development Commission's 'Breakthrough Ideas' competition reveals a few concepts that have previously been discussed in depth in Construct Ireland.

Following my last post on the debate that broke out in the Guardian about using biochar (just another term for charcoal really) to mitigate climate change, Peter Read became the fourth person to write an article in response to George Monbiot's initial criticism of biochar's proponents.

Fine Gael launched its economic stimulus plan yesterday, an investment programme the party says will create 100,000 jobs within five years.
