Green Roofs Coming to Toronto

- Adam Clare 1 Comment

Toronto is set to implement a law that would make green roofs mandatory for tall buildings. Being Toronto, the policy is confused and is arguably not bold enough, but the fact that this is being tabled with support across the city is a very good sign. Torontoist author Toodd Aalgaard has a look at the green roofs coming to Toronto:

After January 30, 2010, according to a draft version [PDF] of the by-law being tossed around today, every building “with a gross floor area of 5,000 square metres or greater shall include a green roof,” meaning that rooftops greater than five thousand square metres in area will require 30% green coverage, with 60% for rooftops exceeding twenty thousand square metres. Further, the construction and maintenance of new roofing will toe strict guidelines laid out in the Green Roof Construction Standard [PDF], ranging from assembly and load bearing to fire safety and plant selection. Even minimal alterations will be subject to City approval.

The Globe and Mail also examines Toronto’s green roof law:

The proposed bylaw would mandate specially irrigated rooftop gardens that are said to reduce air-conditioning costs and mitigate the “urban heat island” effect blamed on pavement and dark roofs.

Part of Mayor David Miller’s climate-change initiative, the move was deferred for fine tuning yesterday and was to return to a meeting next month of the city’s planning and growth committee.

Eco-Friendly Golf Courses

- Adam Clare 1 Comment

I never thought I’d be writing about golf courses on this site because golf courses are absolutely awful for the environment. They use lots of pesticides and consume insane amounts of water – all so people can hit a ball into a hole. So, it is with shock that I find out that there are at least seven eco-friendly golf courses on this planet. These are places I’d try to hit a ball!

Machrihanish Dunes, Scotland

This course in Scotland, opening this May, is historic in a number of ways. It’s being built on a Site of Scientific Interest (SSSI), the first time this has ever been allowed. The course steers clear of the rare native plants for its fairways and makes only less important grounds in play. It’s also literally inspired by golf history. The course will use no pesticides, chemicals or non-natural irrigation systems at all. Not even heavy machinery is allowed on the course. It will be a throwback to how the game started, a real natural links course built out of the sand dunes near the Mull of Kintyre. The course’s naturalist approach to the game is a lesson Donald Trump, who has been trying to build a 1 billion pound golf resort on wetlands nearby, would do well to learn.

Urbanites Pollute Less

A Canadian study has looked at how much carbon per capita a person living in Canada produces and the conclusion is that if you live in a city you produce less carbon. Once more it’s proven that living in an urban centre with high density is better for the environment than urban sprawl.

When it comes to climate change pollutants, Toronto residents are among the greenest in Canada, says a new study.

The report, published in the April issue of the journal Environment and Urbanization, says metropolises, commonly denigrated as big, dirty places, are in fact spewing fewer greenhouse gases per capita than the rest of their countries.

“Blaming cities for climate change is far too simplistic,” said author David Dodman, a researcher at the International Institute for Environment and Development in London, England. “There are a lot of economies of scale associated with energy use in cities. If you’re an urban dweller, particularly in an affluent country like Canada or the U.K., you’re likely to be more efficient in your use of heating fuel and in your use of energy for transportation.”

Dodman found that the average Canadian is responsible for 24 tonnes of greenhouse gas emissions each year, while Torontonians just 8.2 tonnes.

Global Recession Saving Globe

- Adam Clare 1 Comment

The great thing about this global recession that we’re in is that the planet has a bit of time to breath and recover from the destructive force of modern hyper-capitalism. I honestly hope that as we start to recover from this recession we’ll have realized that we need to work with the ebbs and flow of ecosystems and not just exploit what finite resources the ecosystems create.

An interesting theme has begun to emerge in Copenhagen: that the financial crisis might end up saving the world. Sure, it’s painful now, this line of thinking goes, but it gives us a chance to build a low-carbon global economy that we might not have had otherwise. And in the meantime, greenhouse-gas emissions could fall sharply as a result of depressed economic activity — factories closing, less driving, less flying, and so on.
Two influential English economists argued as much today at the International Scientific Congress on Climate Change. In a morning plenary talk, Nicholas Stern of the London School of Economics and Political Science explained the reasons why he’s more optimistic about the likelihood of a new, effective global climate agreement today than he was two years ago: the rapid advancement of low-carbon technology, the deepening of public awareness, the Obama administration’s commitment to cutting greenhouse-gas emissions to 80 percent of 1990 levels by 2050 — and the fact that the recession provides an opening for completely remaking the global energy economy. “It should be easier because we have an economic crisis,” he said. Labor is cheap, after all. That will make it cheaper to hire the workers to, for instance, rebuild the electrical grid in both the U.S. and Europe. Besides, he argued, the financial crisis offers a clear lesson. With this financial catastrophe fresh in our minds, we should realize more than ever that if we wait to address a looming crisis, it will bite us that much harder in the end.

Ten Ways to Save the World

- Adam Clare

There are many ways we can save the world and some may sound crazier than others. The independent has complied ten ways to save the world that range from easy to the hard.

Rethink cars

Motoring could be revolutionised if cars were marketed like mobile phones – in a manner that would cut carbon dioxide and reduce the cost of driving. Motorists would get subsidised – or possibly even free – electric cars in the same way that customers currently get mobile phone handsets. In return, they would take out a contract for miles, rather than minutes, entitling them to get power either by plugging in to recharging points (at home, in car parks or on the street) or exchanging batteries at filling stations. The idea is the brainchild of a thirty-something former dot-com entrepreneur, Shia Agassi, who believes it would halve motoring costs. It sounds too good to be true, but Israel, Denmark, Hawaii and San Francisco are already starting to put the system in place – and even Gordon Brown has toyed with the idea. But to tackle climate change properly, the electricity has to be provided by renewable sources or nuclear power rather than fossil fuels.

Embrace scum

Slimy scum could prove our saviour, as algae are emerging as one of the most promising and environmentally friendly sources of biofuel. Algae can grow extraordinarily fast, doubling in weight several times a day. They produce at least 15 times as much fuel per hectare as conventional crops like corn or oilseed rape, and do not take up farmland needed to grow food; they can be grown in lakes, the sea or even in the process of cleaning polluted water. Algae take three times their own weight of carbon dioxide from the air while growing, and the fuel they produce packs much more power for its weight than other biofuels. It is therefore being developed as a potential carbon-neutral way of fuelling aircraft: Air New Zealand has already mixed it with ordinary jet fuel for test flights. Cars have run on pure algae biofuel, and big oil companies are investing in it.
