On Aug. 10, Shawn Williamson put out his family’s first bag of trash in 26 months. That’s right, 26 months and just one bag of trash for Williamson, his wife, Monica, and their 7-year-old daughter Alyssa.
The Brooklin family recycles, reuses or composts 99.3 per cent of their waste, Williamson calculates. “It’s easier and cheaper,” says the management consultant, who specializes in environmental challenges.
“In my office, there’s a container for compostable materials, one for paper and a small one for garbage.” Asked what’s in the garbage container, Williamson says “cut-up credit cards, old pens, some plastic wrapping … I empty it every four or five months.”
There are only two other small garbage containers in the home. But there are plenty for recycling, composting and a couple of large containers destined for the Goodwill donation centre.
Driving by, no one would guess this is a near-zero-waste home. Williamson insists they don’t have a Spartan lifestyle. In fact, he feels a bit sorry for the rest of us: “If you’re putting out three bags of garbage, you’re wasting an awful lot of time and money.”
It all starts at the store, especially the grocery store. Buying pre-packaged and ready-made food not only creates a lot of trash, it is much more expensive and less nutritious than buying fresh. The Williamsons hit the supermarket once a week with their 12-year-old green plastic baskets and preprinted shopping list, with the weekly essentials listed to make shopping more efficient and eliminate impulse buying.
“We still buy things like potato chips occasionally, and those bags can’t be recycled.”
They also buy in bulk. Toilet paper comes from an office-supply outlet in a giant box that barely fits in the car. Staples such as rice come in 50-pound bags. The house is outfitted with more shelving than most homes but Williamson insists it doesn’t look like a warehouse.
“Try eating only fresh for a few weeks and you’ll see a health improvement . . . you’ll feel better,” Williamson says.
When the family does order takeout, they bring their own plastic containers. “We bring the big ones and the take-out places tend to fill them up for the same price.” Most of this is just common sense on how to be more efficient, and Williamson believes it has saved his family hundreds of hours.
“Just take a few seconds once a week to think about how to do something better and do it.” Before you know it, you will be living better, saving money and maybe losing a bit of weight, says Williamson.
Nearly all food waste and organic matter goes into a back-yard composter, to be turned into rich top soil for the vegetable garden. Williamson says he gets a bit of a workout digging in the compost and he finds it very relaxing. And it beats driving to the gym.
“It’s really all about living better, living simpler and living smarter.”
Incineration vs. diversion
The Williamsons live in Durham Region, where 60 per cent of residential waste is now being diverted from the landfills in Michigan, where much of Ontario’s waste has been going for the past decade. But Durham and York regions are proceeding with plans to build a $230-million garbage incinerator in south Courtice, near Lake Ontario. To operate efficiently, the natural-gas-powered furnaces will need to be fed thousands of tonnes of garbage around the clock. That will take the emphasis off waste reduction and the need to improve recycling programs, says Shawn Williamson, whose family diverts 99.3 per cent of its household waste.
“The simple solution to Ontario’s perennial garbage problem is not to create any waste,” he says. “We saw a big change by converting all our garbage cans throughout the house into recycling bins and putting a tiny container for garbage inside.”
Ontario’s overall waste diversion rate has risen from 21 per cent in 1992 to about 44 per cent. Toronto’s diversion rate was 45 per cent last year, far short of its target of 70 per cent. San Francisco and Los Angeles are already at 70 per cent. More than half of Toronto’s households are in townhouses and high-rise apartments or condos, where recycling and composting must be taken down to basement bins and the diversion rate is a paltry 15 per cent

The moon has no atmosphere so it is scorching hot (+100C) during the day and bitterly cold (-150C) at night. The Earth has an atmosphere made up of oxygen, nitrogen, carbon dioxide (CO2) and other gases. Over 150 years ago scientists proved that CO2 traps heat from the sun. We also know without any doubt that burning fossil fuels like oil, gas and coal emits CO2.
Measurements, not computer models or theories, measurements show that there is now 46% more CO2 in the atmosphere than 150 years ago before massive use of fossil fuels. That extra CO2 is like putting another blanket on at night even though you are already nice and warm.
The Earth is now 1.0 C hotter on average according to the latest measurements. Heat is a form of energy and with so much more energy in our atmosphere our weather system is becoming supercharged resulting in stronger storms, worse heat waves, major changes in when and where rain falls and more.
The Carbon Law says human carbon dioxide (CO2) emissions must be reduced by half each decade starting in 2020. By following this “law” humanity can achieve net-zero CO2 emissions by mid-century to protect the global climate for current and future generations.
A “carbon law” is a new concept unveiled March 23 in the journal Science. It is part of a decarbonization roadmap that shows how the global economy can rapidly reduce carbon emissions, said co-author Owen Gaffney of the Stockholm Resilience Centre, one of international team of climate experts.
“Coal power plants under construction and proposed in India alone would account for roughly half of the remaining carbon budget.” –Steven Davis
To keep the global temperature rise to well below 2°C, emissions from burning fossil fuels (oil, gas and coal) must peak by 2020 at the latest and fall to around zero by 2050. This is what the world’s nations agreed to at the UN’s Paris Agreement in 2015. Global temperatures have already increased 1.1 degrees C.
“After the Paris agreement we began to work on a science-based roadmap to stay well below 2C,” Gaffney told IPS.
The “carbon law” is modelled on Moore’s Law, a prediction that computer processing power doubles every 24 months. Like Moore’s, the carbon law isn’t a scientific or legal law but a projection of what could happen. Gordon Moore’s 1965 prediction ended up becoming the tech industry’s biannual goal.
A “carbon law” approach ensures that the greatest efforts to reduce emissions happen sooner not later, which reduces the risk of blowing the remaining global carbon budget, Gaffney said.
This means global CO2 emissions must peak by 2020 and then be cut in half by 2030. Emissions in 2016 were 38 billion tonnes (Gt), about the same as the previous two years. If emissions peak at 40 Gt by 2020, they need to fall to 20 Gt by 2030 under the carbon law. And then halve again in 2040 and 2050.
“Global emissions have stalled the last three years, but it’s too soon to say if they have peaked due largely to China’s incredible efforts,” he said.
“In the last decade, the share of renewables in the energy sector has doubled every 5.5 years. If doubling continues at this pace fossil fuels will exit the energy sector well before 2050,” says lead author Johan Rockström, director of the Stockholm Resilience Centre.
The authors pinpoint the end of coal in 2030-2035 and oil between 2040-2045 according to their “carbon law”. They propose that to remain on this trajectory, all sectors of the economy need decadal carbon roadmaps that follow this rule of thumb.
“We identify concrete steps towards full decarbonization by 2050. Businesses who try to avoid those steps and keep on tiptoeing will miss the next industrial revolution and thereby their best opportunity for a profitable future,” said Hans Joachim Schellnhuber, director of the Potsdam Institute for Climate Impact Research in Germany.
Elements of these roadmaps include doubling renewables in the energy sector every 5-7 years, ramping up technologies to remove carbon from the atmosphere, and rapidly reducing emissions from agriculture and deforestation.
The immediate must-do “no-brainer” actions to be completed by 2020 include the elimination of an estimated 600 billion dollars in annual subsidies to the fossil fuel industries and a moratorium on investments in coal. Decarbonization plans must be in place for all cities and major corporations in the industrialized world.
Rapidly growing economies in India, Indonesia and elsewhere should receive help to take a green path to prosperity. They cannot use coal as China did because CO2 emissions are cumulative and there is little room left in the global carbon budget, said Gaffney.
This is an extremely urgent issue. India is already on the brink of taking the dirty carbon path.
Davis, who was not involved in the carbon law paper, agrees that rapid decarbonization to near-zero emissions is possible. Cost breakthroughs in electrolysis, batteries, carbon capture, alternative processes for cement and steel manufacture and more will be needed, he told IPS.
All of this will require “herculean efforts” from all sectors, including the political realm, where a cost on carbon must soon be in place. Failure to succeed opens the door to decades of climate catastrophe.
Update: The Trump admin approved the Keystone XL pipeline Friday March 24, 2017. My article from 2011 details how Keystone will be an export pipeline since the US is awash in oil. This even more so today. The Keystone project is only about selling Canadian oil to countries in Asia or Europe. Meanwhile Americans living along the route are stuck with the consequences and the costs of a spill. — Stephen
“The only way Keystone XL could be considered in the national interest is if you equate that with profits for the oil industry”
By Stephen Leahy
UXBRIDGE, Canada, Sep 2, 2011 (IPS)
With four times as many oil rigs pumping domestic oil today than eight years ago and declining domestic demand, the United States is awash in oil.
The country’s oil industry is primarily interested in who will pay the most on the global marketplace. They call that “energy security” when it suits, but in reality it is “oil company security” through maximising profits, say energy experts like Steve Kretzman of Oil Change International, an NGO that researches the links between oil, gas and coal companies and governments.
The only reason U.S. citizens may be forced to endure a risky, Canadian-owned oil pipeline called Keystone XL is so oil companies with billion-dollar profits can…
