  • Sainsbury’s purchase of fish fingers isn’t enough to sustain certified palm-oil

     

     

    The roundtable and the environment group WWF set up a certification system to recognise sustainably produced palm oil. Production began in several countries last year, and in November, five years after the roundtable was set up, the first shipload of certified palm oil arrived in Rotterdam from south-east Asia. “Companies now have the means to buy responsibly,” said WWF’s Rodney Taylor.

     

    So, guess what. Nobody wants it. The stuff has been on sale for six months. But WWF reported last week that “only 1% of the sustainable palm oil available on the market has been bought.”

     

    “So far around 1.3m tonnes of certified sustainable palm oil has been produced, but less than 15,000 tonnes has been sold,” says Taylor. That’s out of a total annual global palm oil production of 28m tonnes.

     

    The trouble is that the certified oil commands a premium price that allows manufacturers and retailers to advertise the products as sustainable. And few companies seem to want to pay the higher price. So the remaining 1.285m tonnes has been poured back into the giant tub of regular palm oil and sold at regular prices.

     

    The only significant buyers of sustainable palm oil identified by WWF are Sainsbury’s in the UK. The retailer has so far bought products such as fish fingers containing 450 tonnes of certified palm oil and plans more products later in the year.

     

    If things continue like this the scheme will crash. And there will be a lot of palm oil growers in south-east Asia – many of whom didn’t see the point of the scheme in the first place – saying “I told you so”.

     

    In fact, if the roundtable operated by the rules it publishes, most of its members might have been thrown out. The RSPO says that “members are expected to communicate on an annual basis their progress in contributing directly to the production and use of sustainable palm oil … only those members who openly communicate progress will be allowed to continue their participation in the RSPO.”

     

    That “open communication” is ensured by putting the reports up on the RSPO web site. So we can all check that they are sending in their annual reports.

     

    I wondered how UK retailers were getting on? All the big supermarkets are members of the RSPO. But several have no progress report on the RSPO web site. One is Asda, which two years ago got headlines for a promise to “ban the sale of palm oil from unsustainable sources

     

    Another is the Co-op, self-proclaimed as “Britain’s greenest grocer”. A third is Tesco. Its own website claims it is an “active member” of the RSPO and is “working on incorporating” certified palm oil into its products when they become available. So it’s not exactly up to date there either.

     

    Waitrose has not filed a report to the RSPO web site since 2006. Even Sainsbury’s, the good guys in the WWF press release, are out of time, having last updated in September 2007.

     

    In fact the only two British retailers with up-to-date annual progress reports are Marks & Spencer, which says it is selling six products containing certified palm oil from Colombia, and the electricity company npower, which sent in a note last autumn to say it had dropped plans to burn palm oil in its power stations.

     

    Among British manufacturers that took the trouble to join the roundtable, Cadbury, Northern Foods and Youngs Seafoods have not put progress reports on the website, United Biscuits and Heinz have not filed since 2007 and only Jordans cereals are up to date.

     

    It’s not a pretty picture. Why haven’t these companies been thrown off the RSPO for failing to follow its rules? There is a loophole in the rules that allows them to report “in members’ existing communications with their stakeholders, such as annual reports”, rather than on the website. But hiding the information in corporate reports does not really meet the requirement for “open communication”.

     

    And why join a club if you can’t be bothered to fill in its simple forms to explain how you are upholding its values. Unless of course it was greenwash in the first place.

     

    The RSPO probably only has a few months to get its act together. Companies like Sainsbury’s and food manufacturer Unilever promised when the RSPO was set up that all their products would be made from sustainable palm oil by 2015 – but less than a tenth of 1% of palm oil for sale is sustainably produced. The suspicion grows that few RSPO members really take its rules or its purpose seriously.

  • Ross Garnaut tells senators to pass emissions trading scheme laws.

    He said there was no reason to wait until after the December climate change summit in Copenhagen to introduce an emissions trading scheme, saying he was encouraged by Barack Obama’s leadership ahead of the conference.

    “I don’t think there’s much doubt about where the world is headed,” he said.

    He dismissed research from the Minerals Council of Australia suggesting the Government’s minimum target of a five per cent of 2000 emission levels would cost 24,000 mining jobs over the next 10 years.

    “There’s no reason to think that a regime of ambitious emissions reduction will lead to a net fall in jobs,” he said, adding there would be as many new jobs created as old ones lost.

    Coalition senators have complained about the time they have to examine the ETS legislation before it is debated next week.

    “We’ve received something that’s just slightly bigger than War and Peace, 1300 pages, that’s been launched on our desk,” Barnaby Joyce said.

    The colourful Queensland National said the committee had only been given the time it takes to read a Phantom comic to go through the bills.

    Western Australian Liberal Alan Eggleston said the Government was holding the inquiry even before the close of submissions on June 4.

  • Canadian Research Team Reports Major Breakthrough in Lithium Battery Technology

    — Dr. Linda Nazar, Canada Research Chair, University of Waterloo

    The research team of professor Linda Nazar, graduate student David Xiulei Ji and postdoctoral fellow Kyu Tae Lee are one of the first to demonstrate robust electrochemical performance for a lithium-sulfur battery. 

    The prospect of lithium-sulfur batteries has tantalized chemists for two decades, and not just because successfully combining the two chemistries delivers much higher energy densities. Sulphur is cheaper than many other materials currently used in lithium batteries. It has always showed great promise as the ideal partner for a safe, low cost, long lasting rechargeable battery, exactly the kind of battery needed for energy storage and transportation in a low carbon emission energy economy.

    “The difficult challenge was always the cathode, the part of the battery that stores and releases electrons in the charge and recharge cycles,” said Dr. Nazar. “To enable a reversible electrochemical reaction at high current rates, the electrically-active sulfur needs to remain in the most intimate contact with a conductor, such as carbon.”

    The Canadian research team leap-frogged the performance of other carbon-sulfur combinations by tackling the contact issue at the nanoscale level. Although they say the same approach could be used with other materials, for their proof of concept study they chose a member of a highly structured and porous carbon family called mesoporous carbon. At the nanoscale level, this type of carbon has a very uniform pore diameter and pore volume.

    Using a nanocasting method, the team assembled a structure of 6.5 nanometre thick carbon rods separated by empty three to four nanometre wide channels. Carbon microfibres spanning the empty channels kept the voids open and prevented collapse of the architecture.

    Filling the tiny voids proved simple. Sulfur was heated and melted. Once in contact with the carbon, it was drawn or imbibed into the channels by capillary forces, where it solidified and shrunk to form sulfur nanofibres. Scanning electron microscope sections revealed that all the spaces were uniformly filled with sulfur, exposing an enormous surface area of the active element to carbon and driving the exceptional test results of the new battery.

    “This composite material can supply up to nearly 80 percent of the theoretical capacity of sulfur, which is three times the energy density of lithium transition metal oxide cathodes, at reasonable rates with good cycling stability,” said Dr. Nazar.

    What is more, the researchers say, the high capacity of the carbon to incorporate active material opens the door for similar “imbibed” composites that could have applications in many areas of materials science.

    The research team continues to study the material to work out remaining challenges and refine the cathode’s architecture and performance.

    Dr. Nazar said a patent has been filed, and she is reviewing options for commercialization and practical applications.

  • Air-fueled Battery Could Last Up to 10 Times longer

     

    Improved capacity is thanks to the addition of a component that uses oxygen drawn from the air during discharge, replacing one chemical constituent used in rechargeable batteries today. Not having to carry the chemicals around in the battery offers more energy for the same size battery. Reducing the size and weight of batteries with the necessary charge capacity has been a long-running battle for developers of electric cars.

    The STAIR (St Andrews Air) cell should be cheaper than today’s rechargeables too. The new component is made of porous carbon, which is far less expensive than the lithium cobalt oxide it replaces.

    This four-year research project, which reaches its halfway mark in July, builds on the discovery at the university that the carbon component’s interaction with air can be repeated, creating a cycle of charge and discharge. Subsequent work has more than tripled the capacity to store charge in the STAIR cell.

    Principal investigator on the project, Professor Peter Bruce of the Chemistry Department at the University of St Andrews, says: “Our target is to get a five to ten fold increase in storage capacity, which is beyond the horizon of current lithium batteries. Our results so far are very encouraging and have far exceeded our expectations.”

    “The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery,” says Bruce.

    The oxygen, which will be drawn in through a surface of the battery exposed to air, reacts within the pores of the carbon to discharge the battery. “Not only is this part of the process free, the carbon component is much cheaper than current technology,” says Bruce. He estimates that it will be at least five years before the STAIR cell is commercially available.

    The project is focused on understanding more about how the chemical reaction of the battery works and investigating how to improve it. The research team is also working towards making a STAIR cell prototype suited, in the first instance, for small applications, such as mobile phones or MP3 players.

  • Owner of Coles imposes salary freeze for board members, senior executives

    Executive bonuses are determined in two parts, the individual component and the financial performance component.

    The individual performance part of the bonus isn’t being paid as part of this cost-saving measure, and relates to non-financial performance factors such as management and safety sustainability, for example.

    Executives can still collect performance bonuses for meeting the financial targets in their given divisions.

    Wesfarmers could save up to $4.5 million from this measure.

    The conglomerate had already put its employee share scheme on hold as a result of the Australian Government’s taxation plan on those programs.

    Australia’s federal Government, as part of its recently unveiled budget, announced plans to tax employees up-front when they are granted share discounts, or options on shares, rather than when they take ownership of the shares, or sell them.

    Mr Goyder said in his letter that he was disappointed by the proposal and that Wesfarmers planned to make “strong representations” to the Government about the matter.

  • CPRS will lock out massive jobs boom

    “The Rudd Government’s Continue Polluting Regardless Scheme sandbags the
    old, polluting economy instead of embracing the tremendous potential of
    wholesale economic transformation.

    “Study after study has shown that a serious plan to transform Australia
    into a carbon neutral powerhouse would create a jobs boom, but a weak
    target and $12.6 billion in handouts to the biggest and noisiest
    polluters simply cannot deliver.

    “To deliver a clean energy jobs boom, we need jobs and training packages
    for workers most at risk in the old economy. We need an industry and
    manufacturing plan, along with policies to roll out renewable energy,
    energy efficiency, public transport systems and an intelligent grid, to
    create the jobs. And we need to aim high, with a strong emissions target
    that will actually protect the climate.

    “The Greens have been promoting these positive, jobs-creating policies
    for years, but the old parties are closing ranks with the old polluters
    and are locking out the climate and the community.

    “The Australian community expects the Minerals Council to fight tooth
    and nail for their short-term interests, but they have a right to expect
    their Government to stand up for Australia’s long-term future.

    “Tragically, the Rudd Government is more interested in listening to
    industry rent-seeking than the community demands for action to prevent
    climate crisis.”
