Britain has about 250,000 vegans as of the end of 2006, while a typical vegan in the world emits 1.5 tonnes CO2 less than a typical meat-eater because it takes 7kg of feed to produce 1kg of beef, for example, and there’s also all that methane from farting cows and nitrous oxide from fertilizer.

There’s a lot of health benefits to being vegan, but also a lot of challenges just to stay healthy because it is hard to get all the nutrients you need to stay healthy in the quantities you need, like iron.

Looking at this statistic, you should be concerned about your health in your ability to go vegan if you are considering it, and not the nobility of global warming. You can offset the 1.5 tonnes CO2 for about $45, which is a LOT less than the cost you’re going to incur in eating meat compared to going vegan, or your doctor and health bills if you don’t go vegan sufficiently to sustain your health.

I’m not against one or the other. I’m a meat-eater, to be upfront. However, I’m not going vegan because I know I can’t without devoting far more of my life to my diet than I care to do to get the proper requirements to not only stay healthy but also to marathon training. I know others who do it and I know I can’t do what they do so props to them. I’m just trying to put things into perspective, which is part of my purpose in having this blog.

However, here is some great advice from the source article below on how to be a “caring carnivore”, a term that must just make the vegans and vegetarians cringe! [Envirostats author] 

How to be a caring carnivore

* Elect to eat one or two organic, locally produced cuts of meat a week rather than eating cheap processed meat every day

* Roast a chicken and live off it for a week, making stock from the bones and eating the leftovers – avoiding wastage

* Investigate meat alternatives such as tofu (pictured left), tempeh, textured vegetable protein and Quorn

* Buy organic milk, or try soya (pictured right), almond, oat, hazelnut or quinoa milk instead

* Chicken and pork are more carbon-efficient and produces less methane than beef

* Be aware of other good sources of protein. These include pulses, beans, nuts, seeds and, of course, soya beans

* Many kinds of bread and even some vegetarian products contain unnecessary milk products like whey, buttermilk or lactose, or eggs. Check the packaging and avoid buying non-organic dairy by avoiding these products

In 2005, the US environmental industry generated more than 5.3 million jobs – 10X that of the US pharmaceutical industry – while China’s combined sales revenues in solar heating was about $2.5 billion, with more than 1,000 Chinese manufacturers employing more than 150,000 people.

A nice story on the silver or gold lining of global warming with all the green jobs generated, with more similar statistics attached below as excerpts from the source.

The number of jobs created was what was compared to the pharmaceutical industry, not the revenue generated or anything to do with money where I suspect the pharmaceutical industry would reverse the ratio. It was a bit unfair of the source, UNEP, to pick a big industry that is growing but in no way to the extent, but which makes a lot of money so it has a big presence in people’s minds. [Envirostats author]

- The renewable energy programmes in Germany and Spain are merely ten years old but have already created several hundred thousand jobs.

- The Indian city of Delhi is introducing new eco-friendly compressed natural gas buses that will create an additional 18,000 new jobs. - The ethanol programme in Brazil has created half a million jobs and its bio-diesel programme is specifically designed to benefit hundreds of thousands of mostly poor smallholder farmers.

- By the year 2020, Germany will have more jobs in the field of environmental technologies than in its entire automotive industry.

- In Europe, a 20 per cent increase in energy efficiency would create about a million jobs. The same applies in emerging and developing countries.

14% percent of GHG emissions from all sources in Australia in 2006 was from enteric methane from cattle and sheep, but nothing from kangaroos as they have special bacteria in their stomachs that allow them to have methane free flatulence.

Posted by envirostats on Saturday, December 29, 2007

Methane (CH4) has the global warming potential of 21 compared to CO2, meaning a given mass of methane does 21-23 times the global warming damage to the atmosphere as the equivalent mass of CO2, or in another comparison, it’d take 21-23 times the mass of CO2 to do the same damage as a given mass of methane.

Animal flatulence, as well as human, deliver a significant amount of methane, and thus greenhouse gases, to world GHG emissions. The story was about scientists trying to get farm animal stomachs to work the same way as kangaroo stomachs and eliminate methane from those animals’ flatulence.  [Envirostats author]

Canada’s demand for energy fell by 2.0% in 2006, to 7,643 petajoules from 7,796 petajoules, with 1 petajoule being roughly the equivalent to the amount of energy required to operate the Montréal subway system for one year.

Posted by envirostats on Thursday, December 27, 2007

Great context by Statistics Canada that provided the figure, because probably until you read what 1 petajoule meant, it was just some big amount of energy. Many other great statistics from the source’s analytical summary is below. The source report link is at the end and contains even more with over 120 pages of analysis on Canadian and provincial energy statistics.

You know, our Canadian media might not cover a lot of our environmental statistics like some other countries’ media, but our statistics agency in Statistics Canada is second to none. Too bad some of our other federal departments don’t jump on these to put out announcements and their own articles with more in-depth coverage of some specifics. [Envirostats author]

Most of the 2.0% decline was due to declining consumption in the nation’s industrial and residential sectors that was more than the 2.0% net, but offset by increases in consumption in the transportation sector, particularly fuel used to pipe natural gas, as well as a small increase in the commercial and public administration sector.

Energy use derived from the three main fossil fuels – natural gas, refined petroleum products and coal – declined 1.0%, due to reductions in demand from the pulp and paper, chemical and residential sectors.

The industrial sector, the biggest user of energy, consumed 2.6% less in 2005 than the year before. The reduction was due primarily to two industries: pulp and paper, and chemical. Historically, the industrial sector accounts for just under one-third (31%) of total energy consumption, the highest proportion of all sectors.

Demand slipped 1.1% in the residential and agriculture sector, which accounts for about 20% of total consumption.

Energy consumption increased 1.8% in the transportation sector and edged up 0.5% in the commercial and public administration sector. The transportation sector, the second largest user of energy, accounted for about 30% of final demand.

Crude oil production falls

Canadian companies produced about 146 million cubic metres of crude oil in 2005, down 2.1% over 2004. (A cubic metre contains 1,000 litres). This amounted to about 401 000 cubic metres a day.

While decreases were recorded for all types of crude oil production, the most significant decline occurred in synthetic crude oil where a facility fire hampered output throughout the first three quarters of 2005.

However, production levels in the fourth quarter were strong reflecting the return to normal production in the oil sands area combined with the start up of production at the White Rose Field in offshore Newfoundland and Labrador.

Alberta’s oil sands remain an important source of crude oil production. In 2005, they accounted for over 39% of total crude oil and equivalent production, up slightly from 38% in 2004 and well above the proportion of 28% in 2000.

In 2005, the oil sands produced 149 000 cubic metres of oil a day. In 2006, this figure had jumped to an estimated 159 000 cubic metres of oil a day, roughly 50% of Canada’s total crude oil production.

By 2010, oil sands production is forecasted to surpass 477 000 cubic metres of oil a day, or 67% of total Canadian crude oil production. Capital investment is expected to reach an estimated $11 billion in 2006 and $16 billion in 2007.

Exports of crude oil, primarily to the United States, decreased 2.4% from 2004. These exports now account for more than 62% of all Canadian production.

The US Midwest is still the most significant market for Western Canadian crude oil, consuming 57% of total exports to the United States. According to the United States Energy Information Administration, Canadian crude oil now represents 16% of total US demand for imported crude oil.

In 2005, average Canadian crude oil prices rose to more than $52 a barrel. This was a 30% increase over 2004, and more than double 1990 prices.

Natural gas production posts modest gain

Natural gas production increased 2.0% in 2005 from 2004. Despite record gas drilling activity in the last three years, production gains have been modest as a result of lower productivity from maturing wells.

Natural gas exports reached 4 066 petajoules in 2005, up 1.1% from 4 022 petajoules in 2004. Slightly higher production levels combined with lower domestic demand, due to milder weather in Canada, resulted in higher exports in 2005.

Well over half (56%) of total Canadian natural gas production goes for export. In the United States, Canadian natural gas accounts for 17% of total American demand for natural gas.

Canada’s trade surplus for crude petroleum, refined petroleum and other products, natural gas, coal and electricity reached $53.0 billion in 2005, up from $43.5 billion the year before.

Marginal increase in electricity production

Electricity production from primary sources (hydro, nuclear, wind and tidal) increased 5.7% in 2005 as water conditions continued to improve in many parts of Canada. Nuclear generation posted a marginal increase in 2005.

Hydro generation accounted for 59% of electric power in 2005, the largest source. Nuclear energy provided about 14% of total Canadian electricity production.

However, in Ontario, nuclear power accounts for more than 51% of total electricity generation, enough to supply all the homes in the province.

Nationally, electricity generated using fossil fuels declined marginally in 2005, due to higher generation from primary sources and rising thermal fuel costs.

Although electricity generation from wind, solar and tidal continues to increase, total generation from these sources currently represents less than 0.5% of total generation.

Two large wind projects started up in late 2005: a 99-megawatt project located in St. Leon, Manitoba, and the 150-megawatt “Centennial project” in Swift Current, Saskatchewan.

Electricity demand increased 1.2% in 2005, mainly the result of increased demand by smelting and refining.

First decline in volumes of motor gasoline sales in 14 years

Volumes of motor gasoline sales declined in 2005 for the first time since 1991, possibly the result of soaring prices at the pump. Canadian drivers consumed more than 40 billion litres of motor gasoline, down slightly from 2004 levels.

Gasoline prices across Canada peaked in September 2005. In Montréal, prices reached an average of 118.5 cents per litre for regular unleaded at self-service stations. In Toronto, they averaged 107.2 cents, in Edmonton 102.2 cents and in Vancouver 112.7 cents.

Total demand for all refined petroleum products increased marginally in 2005 over 2004 levels.

Coal production, exports and consumption decreases

Coal production slipped 1.0% in 2005, the result of slightly higher imports.

Final demand for coal by the manufacturing sector declined 1.4% from 2004. Exports of coal fell 6.2%, due primarily to lower demand for Canadian coal from Japan.

Saskatchewan fastest growing province in energy consumption

Energy consumption declined faster than the national average in six provinces: British Columbia, Prince Edward Island, New Brunswick, Nova Scotia, Quebec and Alberta.

Saskatchewan’s growth in consumption led the pack, increasing 2.9% from 2004. Higher demand for natural resource-based products, combined with agricultural gains, contributed more to the growth of the economy than any other industry.

Energy use by all sectors, or “final demand”, declined 3.8% in Prince Edward Island; 2.2% in British Columbia, 1.1% in Alberta and Nova Scotia, 0.6% in Quebec, and 0.5% in New Brunswick.

The decline in Alberta was due primarily to lower energy use in the oil-producing province’s pulp and paper and chemical sectors. Alberta accounted for 18% share of total national consumption.

Energy consumption edged up 0.2% in Ontario , which accounted for over 34% of the country’s entire energy demand. Consumption in Quebec fell slightly, putting its share at 21%.

Japan used 515,414 tonnes of PET plastic for bottling soft drinks in 2006, at a recycling rate of near 65.6% that was in 2005, but which had increased from a mere 0.4% in 1993, though about 180,000 tonnes were still dumped, burned or sold abroad.

Posted by envirostats on Wednesday, December 26, 2007

The increase in rate is amazing! Unfortunately, so is the amount not recycled. The 180,000 tonnes figure is rounded from 178,333 but had to be an estimate in two significant figures to accommodate for the rough estimate for the 2006 recycling rate that was not available, but presumably along the same line as the 2005 rate supplied by the Japanese Council for PET Bottle Recycling.

Source article was about how fashionable some of Japan’s PET softdrink bottles are, and fashionable they definitely are! I’ve always said about Japanese packaging that it is often so beautiful, I would never want to consume or use whatever it held. This is a perfect example. Unfortunately, often times, it is also often excessive, and in more ways than just human efforts put into it. [Envirostats author]
