PFOA Precursors to be phased out

Leftovers may explain perfluorinated compound puzzle:

See my earlier post about this. Looks like the EPA did want the companies to phaseout not just the PFOA, but the precursor compouds as well, and according to this article, quite a bit of progress has been made.

Eight companies have pledged to slash releases of several perfluorochemicals at their operations around the world, EPA announced on March 2.

Arkema, Asahi, Ciba, Clariant, Daikin, DuPont, 3M/Dyneon, and Solvay Solexis have agreed to reduce emissions of perfluorooctanoic acid (PFOA), its longer chain homologs, and compounds that can degrade into PFOA, EPA said. The companies will also reduce levels of these compounds in their products. Responding to a challenge EPA made in January, the eight firms volunteered to cut industrial releases of PFOA as well as amounts of the chemical in products 95% from 2000 levels by 2010 or earlier. The companies also pledged to work on eliminating releases and content of PFOA in products by 2015.

Here are the individual companies’ commitment letters. They all loudly proclaim their commitment to reduce PFOA levels in their products, not quite so universally unequivocal on the precursors… I need a lawyer to parse some of the language. 3M, for instance, says that they do not “manufacture” the telomers’, which is not the same as saying they do not use them. Solvay Solexis, is extremely straigtforward and agrees to the EPA conditions in a letter actually written in plain English! Dupont, good letter too. Let’s see how this situation plays out, outright elimination in 10 years seems nice, which leads me to believe that the companies are already moving in this direction. The journal article suggests that the residuals are mainly due to inefficiencies in the manufacturing process. The reaction yield is 70%, meaning the 30% left behind from the monomer formation reaction will need to be removed from the product.

  • Canada and Climate Change Regulation – Politics as Usual

    Weasel (from wikipedia)

    *Weasel picture courtesy wikipedia

    “We need to hear more about the American position, the European position, the Chinese position” before considering the bill, McGuinty told CBC News.

    CBC

    With that rather weasely statement, Canada’s Liberal Party signalled that it will support a further delay in a vote that would set realistic limits on Canada’s Greenhouse gas emissions. I was too angry yesterday to write a decent post about it, but hey, as my partner often says, “Anger is a positive emotion”. So, here goes.

    What is it?
    Bill C-311 – The Climate Change Accountability Act. aims to set binding emission targets for greenhouse gas emissions (excluding land use, land use change and forestry) for Canada. Here’s the a short sentence from the preamble:

    this legislation is intended to ensure that Canada reduces greenhouse gas emissions to an extent similar to that required by all industrialized countries in order to prevent dangerous climate change, in accordance with the scientific evidence on the impacts of increased levels of global average surface temperature and the corresponding levels of atmospheric concentrations of greenhouse gases;

    Okay, ending a long sentence with a semi-colon, strange, but there it is, a very clear and concise statement of fact intending for Canada to set realistic targets for GHG reduction

    What are the targets?
    25% below 1990 levels by 2020, 80% below 1990 levels by 2050. This is in line with IPCC recommendations (pdf) (See page 776, thanks Climate Progress) to stabilize temperature rise to < 2°C and GHG concentrations to 450 ppm CO2 eq.
    Hansen, other prominent scientists and activists at 350.org have a more ambitious target in mind, 350 ppm. In comparison, proposed legislation by John Kerry and Barbara Boxer in the US senate would reduce GHG emissions by 20% from 1990 levels, and 80% by 2050. So, this bill proposes targets that are in line with what the world’s greatest polluter (per capita, historical) is proposing and current official consensus. There is a lot of small print in the exemptions, agriculture is a big one on the US side and land use and forestry appear to be a rather significant omission on the Canadian side.

    Bottom Line: The targets are exactly what is recommended by the IPCC, are reasonable and in line with what our biggest trading partner has proposed. They need to be strengthened in the near future, but are good for now.

    What it doesn’t do
    It does not establish a mechanism to bring about these reductions, only specifies that the government come up with scientifically sound interim targets and an emissions reduction regulatory strategy, be it emissions trading, or carbon taxes, etc. That’s fine, given Canada’s balance of powers and separation of province-federal powers, it would be best for an executive approach to regulation writing.

    History

    Bill C-311 is not new. An identical version passed the House of Commons in 2008 and was stymied by an election call. Since Canada has a bicameral legislature, the bill needed to be passed by the Canadian Senate as well and the election blocked this vote. Right now, it needs a vote to get out of committee and on the floor of the House.

    So what happened?
    Well, the NDP wanted to get the bill out for vote. The Bloc Quebecois supported them. The Conservatives, in a delaying tactic, wanted to extend the committee study period for another month, citing a “need for more expert testimony”, the Liberals agreed with them and the bill is stalled for now. Why? It is all politics.

    The Politics
    This is where the story gets interesting, and epitomizes everything that is wrong with Canada’s current political system! Canada is currently (since 2006 and 2 elections on), run by a minority Conservative government. Minority governments work very differently in Canada compared with typical parliamentary democracies such as India, Israel, etc. There are no coalitions, no alliances, especially now since the Conservative party is well to the right of every other party in Parliament. Canada has four other prominent parties, the Liberals, a centrist, business friendly party that has previously governed, the NDP, a left leaning union friendly party, the Green party, an environmental issues and good governance driven party (no seats in parliament), and the Bloc Quebecois, a regional party based in Quebec which wins seats only in Quebec.

    For the Conservative party to pass legislation, they need the support of one other party. Of course, to stymie legislation, they can use various parliamentary procedures. This is why C-311 is a private member’s bill, the government, which is vehemently opposed to any meaningful climate change mitigation regulation, would not bring something like this up for vote.

    The NDP would like to be responsible for meaningful regulation on climate change as it is in line with their stated principles and also neatly aligns with their desire to be seen as a serious opposition party, and as a party capable of governing at the federal level.

    The Liberals, well, they ran their last election on a radical restructuring of the Canadian tax system called the Green Shift. This envisaged a reduction in personal income taxes combined with the establishment of a carbon tax. The Liberals lost the election, and have been a lot more cautious about bringing up environmental issues. I happen to believe that the loss was primarily due to poor election strategy, a leader with the charisma of a freshly painted wall, and a flawed electoral system that allows for too much vote splitting, “wasted” votes and is unrepresentative. But, the media has run with the “it must be the environment” meme, and currently view any environmental legislation as a vote loser. This is in direct contradiction with polling data (pdf) that indicates the opposite to be true.

    Anyway, the Liberals appeared to be getting back into the energy game. Their dear leader Michael Ignatieff (@m_ignatieff) recently tweeted about a revolutionary new clean energy plan, which seems sensible enough and forward thinking. Also, the Liberals supported this identical bill last year, and until recently. Here’s the NDP with a collection of helpful quotes from the Liberals on C-311:

    “Parliamentarians don’t know where this country is going, as a sovereign nation state, on climate change. The really good news and the good faith behind Bill C-311 is helping to prompt a timely debate of where we’re going in advance of the important Copenhagen negotiation.” – David McGuinty, Environment Committee, June 18, 2009

    “[Bill C-311] has been reintroduced under a new MP, a bill that was put forward in the last Parliament by the leader of the NDP. As such, it really has no material changes compared to its predecessor bill.” –David McGuinty, Hansard, March 4, 2009

    “It’s very simple: we won’t be taken seriously until we are serious about the environment.” – Speech to the Vancouver Board of Trade, October 13, 2009 – MIchael Ignatieff

    Unfortunately, the price for success against the government in this half-assed minority government situation is likely an election! Opinion polls indicate that an election held today would likely result in very much the same situation as the last time around, maybe even an increased near majority for the Conservatives.

    The Conservatives (in blue) have a solid lead over the Liberals (Red) and the NDP (in orange) apparently have a 20% ceiling. In a normal parliamentary system, this would mean an alliance between the NDP and Liberals to win the election pretty handily (note that the votes would not additive, but there is a conservative vote ceiling around 40%). But as long as electoral reform is off the table, and the extremely hidebound Canadian mainstream media does nothing other than bemoan the lack of electoral participation while roundly condemning any alternative that would increase such participation, we are stuck with ths situation in which a Conservative government takes this country slowly rightward where it really does not want to be taken, given that solid majorities are against said conservative policies.

    In Conclusion
    Canada dithers again on climate change. To the core supporters of the Conservative party, this is as should be. However, for the majority of the country, for the international reputation of the country, and for the political system as a whole, this is an unacceptable delay. The Liberals win no friends by being indecisive and showing no leadership. The NDP is stuck with no amount of “responsible” opposition work giving it any traction in the polls, the political intelligentsia of Canada would not accept an NDP ascendancy. The political system does not reward cooperation. So, we remain stuck, a country of many beautiful words and very little action.

    Happy Friday!

    You breathe in toxic chemicals too.

    Behind a frigging pay wall, as usual! Kelly et al. argue in Science that hydrophobicity, the tendency to favor oil over water (to break it down to the simplest explanation) is not the only factor that explains biomagnification. The underlying theory used to be that compounds that can dissolve in water would swiftly degrade (either chemically or biologically) and not be of any concern to humans. Compounds like dioxins, PCB’s, DDT, etc. accumulated in fat tissue of aquatic animals and these were the compounds that would biomagnify through ingestion (eating!). Kelly et al. uncover another pathway that probably made every scientist go “D’uh”! – Apparently, chemicals animals breathe in can also bioaccumulate if they are not cleared efficiently by the lungs. So, air breathing cows, chickens and pigs can also cause significant bioaccumulation of certain compounds. Which ones? I guess you’ll have to pay to find out more, but this Scientific American article adds some context. Turns out, it is about 10000 chemicals, not all of them known to be harmful, but because they were never suspect, their metabolism is unknown.

    Well, if anything, it will keep the biomonitoring folks busy for a while!

    Chemical Consequences — 317 (5835): 165g — Science

    Global regulators of commercial chemicals apply a scientific paradigm that relates the biomagnification potential of the chemical in food webs to the chemical’s hydrophobicity. However, Kelly et al. (p. 236; see the news story by Kaiser) show that current methods fail to recognize the food web biomagnification potential of certain chemicals. Certain chemicals do not biomagnify in most aquatic food chains, but biomagnify to a high degree in air-breathing animals, including humans, because of low respiratory elimination. Thus, additional criteria for evaluating biomagnification and toxicity in chemicals that biomagnify are required.

  • John Kerry and the Environment

    The fight in the Senate | Gristmill: The environmental news blog | Grist

    Kerry, everyone’s favorite democrat summarizes the non-coal/auto democrat’s energy/environmental policy plans int he US senate.

    Highlights:

    1. Increase Fuel Economy standards
    2. Increase contribution of renewable sources
    3. No drilling in the Alaskan National Wildlife Refuge (ANWR)
    4. No liquid coal
    5. NO MORE COAL WITHOUT SEQUESTRATION!!!

    This is all very sensible. He does not mention biofuels/corn ethanol, which I guess is because he’s from Mass, not exactly corn central.

    He’s a good man, this John Kerry.

  • Canadian Federal Government GHG Mitigation – FAIL

    Two central programs that the Conservative government has claimed will result in significant reductions in Canada's greenhouse gas emissions are nearly impossible to verify, the federal environment commissioner says.

    A tax credit intended to encourage public transit use, part of the maiden Tory budget in 2006, will “lead to negligible reductions” in Canada's greenhouse gas emissions and the tools to measure its impact don't yet exist, Scott Vaughn's audit of the government's tools for cutting air emissions found.

    And impressive claims that a $1.5-billion climate change trust fund would lead to an 80-megatonne cut in emissions by giving provinces money to go green appears to be based more on a best-case scenario that may be flawed, the audit found.

    Not that the Conservative government is serious about its climate change mitigation strategies. Their programs were easily tagged as worse than useless. A transit tax credit is useless without increasing transit options, discouraging urban sprawl and increasing automobile fuel efficiency. I like the fact that I can get $10 off a monthly bus pass with this program, but in the end, most people will pay 10 bucks a month if it means getting to work in half an hour, instead of an hour and 15 minutes. When you use exclusively tax based solutions, everyone optimizes their short term gains and nothing happens in the long term.

  • Wow, Conventional Milk makes Twins!

    44m.jpgHoly tentacular twins, Batman! This is crazy news, the first study linking the incidence of twins with environmental factors. The culprit is growth hormone fed to cows to increase milk production. According to this Wikipedia article, a third of all dairy cattle use Monsanto’s rBGH (or rBST) brand Posilac®, so obviously, use is widespread.

    FEED – July 2006 (from the Union of Concerned Scientists)

    1. Engineered hormone in milk may be linked to twinning. A recent study found that women who consumed dairy products were five times more likely to give birth to twins than vegan women. The study suggested that the use of engineered bovine growth hormone/bovine somatotropin (BGH/BST) to boost milk production in dairy cows may be related to the higher level of twinning. BGH is known to increase twinning in dairy cows. In addition, the rate of human twinning is twice as high in the United States, where BGH is used, as in Britain, where BGH is banned. BGH affects twinning rate by increasing insulin-like growth factor (IGF), a protein produced in the milk of both animals and humans, that promotes ovulation and may help early-stage embryos survive. A separate study found that levels of IGF were 13 percent lower in vegan women than in women who consumed dairy products. Read a press release about the study, which was published in The Journal of Reproductive Medicine.

    If true, no woman should ever drink “conventional” milk (non-organic, non rGBH free, etc). Twins are fun, I love my twin nieces very much, but they are much more difficult to carry and deliver, and there are more complications.

    Scary, but I suspect this is the tip of the iceberg as far as environmental effects on childbirth are concerned.
