    Will veganism save the planet?

    Researchers from Oxford concluded that consumers have significant power to 'deliver environmental benefits on a scale not achievable by producers' by excluding animal products from their diets. Interestingly, this report comes at a time when the uptake of veganism is growing significantly, both globally and in Australia.

    Forecast: political storm over energy

    Summer is here, and so is the political spin about blackouts. This year, with a record November heatwave in Victoria and a press gallery hypersensitised to energy politics, the blame game started early - well before anything has actually gone wrong.

    Electric carmaggedon

    There are lots of reasons why China wants to accelerate the uptake of electric vehicles. It desperately needs to curb air pollution, which the World Health Organization estimates kills more than a million of its citizens each year. It also wants to reduce dependence on imported oil, and help meet climate change targets. Most crucial, however, is China's intention to dominate the global market for electric vehicles and the technology that powers them, lithium-ion batteries.

    'The evening news has become like a nature hike through the Book Of Revelations,' says Al Gore, the politician-cum-climate activist who made waves with his Oscar-winning 2006 documentary An Inconvenient Truth.

    Tolkien's inspiration for climate advocates

    To Tolkien, 'the long defeat' described the idea that so often in the world you find yourself fighting for a cause where there is very little chance of success, but you fight for it anyway because it is the right thing to do and because you can't imagine doing anything else. He paired this with the concept of eucatastrophe, a sudden and unexpected change of fortune for the better. Despondent climate activists do well to remember that the latter doesn't come without the former.

    Getting off gas not so easy for renters

    Standard electric heaters turn roughly one unit of electricity into one unit of heat. A reverse cycle air conditioner, however, uses electricity to 'pump' heat from one place to another and is incredibly efficient. Using electricity from the grid creates more pollution than burning gas, but the electric reverse cycle air conditioner is so efficient it's still less damaging overall. That's great news for households with air con, but galling for anyone who can't afford one, or isn't allowed to install it.

    Is your super doing dirty work?

    An accelerating number of institutions and individuals are moving their money out of planet-heating fossil fuels and into climate solutions. The total assets guided by some form of divestment policy was $3.4 trillion at 2 December last year, 50 times more than what was up for divestment 12 months earlier. It sounds like a lot, but it's a small amount compared to the $100 trillion-plus invested in the usual way. That's our money, in banks and super funds, managed funds and insurance companies.

    Sulphur sunshade is a stupid pollution solution

    Geoengineering means intervening in the Earth's climate to offset global warming. It's hacking the planet on a monumental scale. The most widely studied proposal is spraying sulphate particles into the upper atmosphere to reflect sunlight, cooling the planet. The idea comes from huge volcanic eruptions, which can blast millions of tonnes of sulphur into the stratosphere, creating a kind of chemical sunshade. After decades of being taboo, this outlandish scheme is now being taken seriously.

    A word to the wise on selling climate action

    The best known examples of framing come from American cognitive linguist George Lakoff. He argues that George W. Bush replaced the phrase 'tax cuts' with 'tax relief' to reframe paying tax as an affliction. Embedded in those two words is a neo-conservative worldview against government intervention in the private sphere. If you accept the term, you absorb the worldview. In a similar way, a few words could build political will to tackle climate change. The problem is no one is sure what they are.

    Political roadblocks to Sydney's electricity evolution

    In the early 1990s London engineer Allan Jones took the suburb of Woking off the grid by establishing a system of tri-generation, which reduces waste by generating power locally. The Sydney City Council employed Jones in 2009 to bring the same approach to Australia. But regulations from previous eras that greatly favour the incumbent power companies are preventing any meaningful change. Once again we find that the main challenges with tackling global pollution are not technical, but political.

    Self-righteous road use causes accidents

    Better infrastructure such as dedicated bike lanes helps to avoid cyclists being injured. But the road is not a battleground and increased armoury is not the answer to our need for safer roads. A more gracious attitude to each other on the part of both motorists and cyclists is just as important.

    China calls a halt to dirty coal imports

    From 1 January 2015, China will ban the import of coal with high ash or sulphur content and impose a three per cent tariff on all coal imports. In the muddle of politics and policy, we have a concrete example of worsening environmental conditions forcing policy makers to act. Australia's economy propped up by coal exports, but it's also time to think beyond the specific implications of China’s proposed restrictions.
