  1. Montreal Protocol outshines Kyoto PETER HADEKEL, The Gazette Published: 6 hours ago It's been described as the most successful global environmental agreement ever negotiated. The Montreal Protocol, signed in 1987 and ratified by 191 countries, has been extraordinarily effective in phasing out the use of harmful chemicals that depleted the the ozone layer in the Earth's stratosphere. The agreement showed that the global community really could respond to a serious environmental threat. [/url] Twenty years later, environmental officials from government and industry are meeting this week, at a United Nations conference in Montreal, to assess their progress and recommend further action. And some are asking whether the Montreal Protocol could serve as a template for action on a far bigger and more complex problem - greenhouse gas emissions. Despite progress in eliminating 95 per cent of ozone-depleting chemicals, there's still more that can be done to protect the ozone layer, said Mack McFarland, a scientist at chemical giant E.I. DuPont de Nemours and global environmental manager of the company's fluorochemicals business. The phase-out for developing countries could be speeded up, he said in an interview yesterday. That's one proposal on the agenda at this week's meeting. The ozone layer acts as a filter in the Earth's stratosphere, absorbing harmful ultraviolet radiation from the sun. By the mid-1980s, gaping holes in the layer had begun to appear, linked to the world's consumption of such chemicals as halons (in fire extinguishers) and chlorofluorocarbons, or CFCs (in refrigeration, air conditioning and aerosol propellants). After scientific proof was published about the the causes of ozone depletion, industry began to acknowledge its role in the problem, McFarland said. DuPont, which had invented CFCs, began to call for their elimination a year before the Montreal Protocol was signed. Progress was rapid in eliminating use of most ozone-depleting substances, he noted. "In developed countries, halons were gone by 1995, and CFCs by 1996." As of 2005, more than 95 per cent of all the chemicals controlled by the protocol had been phased out. But healing the stratosphere will take longer, because chemical residues will be present for a while. The United Nations Environment Program estimates that the ozone layer should return to pre-1980 levels by 2050 to 2075. Health benefits will be substantial as the ozone layer is restored. It's estimated that the global community will avoid millions of cases of fatal skin cancer and save trillions of dollars in health-care costs. "At this stage, the question is: Is there more that can be done to protect the ozone layer," McFarland asked. Use of less damaging HCFCs is still being ramped down, but could be speeded up in both developed and developing countries, he said. Six groups of countries have presented proposals to accelerate that process. Industry has poured hundreds of million of dollars into research and development of safer chemical substitutes for use in such processes as refrigeration. One result, McFarland said, is that production of global warming gases has also been reduced. Between 1990, when ozone-depleting substances were at peak levels, and 2000, the elimination of those chemicals yielded a net reduction of 25 billion tonnes of global-warming gases. Can the success of the Montreal Protocol serve as a model for tackling climate change? In one respect, it can, McFarland said, because a science-based approach was followed and countries, while agreeing to respect targets, were to free to implement the Montreal Protocol as they chose. Also, realizing that science and technology were not static, there were provisions to revise the Montreal Protocol at least every four years. Of course, a critical difference is that developing countries were on board from the start. That's not the case with the Kyoto Protocol on climate change. "The climate change issue is many orders of magnitude more challenging," McFarland said. "We're dealing with the very fabric of our society - the way we produce and use energy. "You've got to make sure that the goals you set under these international agreements are achievable." phadekel@videotron.ca

  4. Canadian smog costs $1 billion, 2,700 lives: CMA Canwest News Service Published: Wednesday, August 13, 2008 The Canadian Medical Association estimates that by 2031, more than 4,900 Canadians, mostly seniors, will die prematurely each year from the effects of polluted air.Dean Bicknell/Canwest News ServiceThe Canadian Medical Association estimates that by 2031, more than 4,900 Canadians, mostly seniors, will die prematurely each year from the effects of polluted air. OTTAWA -- Smog this year will contribute to the premature deaths of 2,700 Canadians and put 11,000 in hospitals, costing the economy and health-care system $1 billion, Canada's doctors say. A report by the Canadian Medical Association calculates that deaths linked to air pollution will rise over the next two decades, claiming nearly twice as many lives each year and costing $1.3 billion annually in health care and lost productivity. The study estimates that by 2031, more than 4,900 Canadians, mostly seniors, will die prematurely each year from the effects of polluted air. Ontario and Quebec will bear the brunt, with smog-related deaths soaring among aging baby-boomers and the chronically ill. In Ontario, the number of premature deaths could double, to 2,200, from 1,200 per year, while hospital admissions over the same period could jump by as much as 70%. The annual health-care and economic costs could rise by as much as 30%, to $740 million, from $570 million. Quebec's mortality rate could rise by 70%, from 700 a year to 1,200, while hospital admissions could spike by 50% annually, costing the province 10% more, or up to $290 million a year. While smog can trigger lung problems, accounting for up to 40% of hospital visits, heart attack and stroke are the real problems, responsible for more than 60% of all air-pollution-related hospital admissions, the study found. Pollutants such as nitrous oxide damage the heart by harming blood vessels, leading to atherosclerosis, a disease that makes people susceptible to heart attack and stroke. Besides the direct costs to the economy and the health system, the study tries to put a price on the poor quality of life and loss of life caused by smog-related deaths. With those estimated costs included, this year's total bill -- in addition to the $1 billion estimate for economic and health-care costs - would amount to more than $10 billion. That figure would rise to $18 billion a year by 2031, with nearly $16 billion of that the price the doctors' association puts on lost lives. But Gordon McBean, a renowned climatologist at the University of Western Ontario, questioned the accuracy of such estimates. While he praised the report and called most of its data sound, he said the attempt to put a price tag on lost life is problematic. "Health-care costs you can do a reasonably good job quantifying, but quality of life and the actual value of life is a bit difficult," said Mr. McBean, co-author of a recently published Health Canada report on the impact of climate change on human health. As a Canadian representative to the Nobel Prize-winning Intergovernmental Panel on Climate Change, Mr. McBean said the world's top experts have tried unsuccessfully to come up with similar estimates for the human cost of climate change. "That became very controversial because the people who did it said, 'Well, a North American is worth so many thousand dollars and an African is worth a small fraction of that.' And people like me didn't think that was acceptable," he said. Given that climate change likely will lead to more smoggy days, the report does not exaggerate the level of anticipated deaths caused by air pollution, said Mr. McBean. "They're not overstating the problem. If anything, these are lowball estimates."
  5. Battle lines drawn on environment at premiers rendezvous in Quebec City LEE GREENBERG and MARIANNE WHITE, Canwest News Service Published: 5 hours ago Alberta Premier Ed Stelmach issued a stern warning against a national cap-and-trade program yesterday, underscoring divisions among Canada's 13 premiers and territorial leaders at the outset of a three-day meeting featuring discussions on climate change strategy. Stelmach and Saskatchewan Premier Brad Wall scuttled any hope of a unified cap-and-trade program, making it clear they consider the policy a thinly disguised attempt to share in the billions generated by western oil and gas. "There's only one inter-regional transfer of wealth in this country and it's called equalization," Stelmach said. Sam the man and the premiers: An actor portraying Samuel de Champlain mingles with provincial premiers and territorial leaders attending the Council of the Federation in Quebec City yesterday. "There won't be another one from the province of Alberta. And that's as straight an answer as I can give." "We will fight aggressively against any initiative that would redistribute not just wealth, but opportunity, and threaten our 'have' status," Wall added. "Because (our prosperity) is good for the country." The two Prairie premiers placed themselves squarely against Ontario and Quebec, which recently announced their intention to begin a cap-and- trade program in 2010, as well as B.C. and Manitoba, which have both signed on to cap-and-trade programs under the aegis of the Western Climate Initiatives. The group also includes Quebec and seven U.S. states. Cap-and-trade would require companies exceeding emissions caps to trade for credits from greener firms. Both Wall and Stelmach cast aspersions on the viability of cap and trade, touting instead carbon capture and storage (CCS) technology. Alberta last week announced a $2-billion investment in CCS, also known as sequestration, a process that aims to store carbon emissions by injecting them into deep geological formations. Most provinces have at least something in common when it comes to climate change - they have better plans to tackle it than Ottawa, according to the report released yesterday by the David Suzuki Foundation. As the premiers gathered for the Council of the Federation, the conservation group noted that almost all provinces are stepping up with strong targets and policies in the absence of federal leadership. The report card shows that British Columbia is leading the pack with its carbon tax. The Suzuki Foundation gives a good rating to Quebec and Ontario for their policies to reduce greenhouse gas emissions and their proposed cap-and-trade system. Manitoba also gets the thumbs-up. Not surprisingly, Alberta rated the worst, with Saskatchewan not far from the bottom. "For Alberta to be moving backward is incomprehensible," said Dale Marshall, climate-change policy analyst with the Suzuki Foundation.
  6. Harper is on the second day of a three-day tour of Europe, with environmental issues at the centre of the agenda. Most European countries are wary of Canada's mixed record on the Kyoto Protocol for greenhouse gas emissions, with far more political and public support for reductions in Europe than is generally found in this country. Before he left, some environmentalists criticized the prime minister's trip for its own greenhouse gas emissions. They say the air travel involved in taking Harper's retinue to several European cities in three days will generate more than 400 tonnes of carbon dioxide emissions, as much as 100 cars produce in a year. But Harper and his officials say expressing Canada's position on climate change is crucial, as well as discussing this country's booming trade with Europe, worth some $110 billion in the past year. Speaking to UN delegates in Bonn, Harper said Canada was the first industrialized country to ratify a biodiversity treaty in 1992, and that this country took a varied approach to environment protection, involving all sectors of society, and not just government. "Canada has gone to great lengths to protect and preserve our rich and diverse environment," Harper said in Bonn. "In our country, this is not just a government enterprise. We are partnered with many private individuals, corporations and non-governmental organizations dedicated to environmental philanthropy." CBC's chief political correspondent, Keith Boag, travelling with the prime minister, said there was little about the address that was new in policy terms. "The speech was really just a once-over-lightly about how beautiful Canada is," Boag said. "How many lakes and rivers and streams and mountains and forests and fields and so on [the country] has." The Bernier resignation is still very much on the mind of the prime minister and officials and journalists travelling with him, Boag said. Canada could do more: environmentalists Environmental groups at the Bonn meeting say there is sometimes more words than substance to Canada's positions on biodiversity and other environmental issues. William Jackson with the International Union for the Conservation of Nature said Canada can be proud of its domestic achievements in environmental protection, but its international role in holding up agreements on issues like climate change has raised eyebrows. "I have not seen Canada blocking things to the point [that] decisions are not being made," Jackson says, "but I've seen them expressing their views strongly." Federal Environment Minister John Baird, who is with Harper, dismissed accusations Wednesday that Canada isn't doing enough to curb greenhouse gas emissions. Baird said the Canadian government actions include regulating big polluters, a hydrogen initiative in B.C., encouragement of carbon capture and storage efforts, an electricity grid between Ontario and Manitoba and support for tidal power generation in the Maritimes. Harper was hoping to convince European leaders that his plan for fighting greenhouse gases is a good one, despite criticism from environmentalists. Unlike most of Europe, Canada and the U.S. oppose any new climate change pact that would exclude major polluters, such as China or India. Harper is using this trip to lay the groundwork for the upcoming G8 meeting this summer in Japan, which will focus on climate change. On Wednesday in Bonn, Harper is also meeting German Chancellor Angela Merkel. The two leaders pledged last year to increase co-operation between their two countries on a range of issues, including environmental policy and trade. Harper's next stop will be Rome for meetings with Italian Prime Minister Silvio Berlusconi before travelling to London where he has meetings scheduled with the Queen and his British counterpart, Gordon Brown, as well as a speech to business leaders at the Canada-United Kingdom Chamber of Commerce.
