  • Australia’s CRC changes calculations for greenhouse emissions

    Embedded in Australian accounts: The AGO has utilised these
    findings in the National Greenhouse Gas Inventory, adopting new factors
    which lower the estimates of Australia’s greenhouse gas emissions. “The
    results have attracted interest nationally and internationally with
    presentations in Japan and the USA being supported by the research
    community, the waste and forestry sectors, and accounting bodies,” said
    the 2005 annual report.

    The wood not the trees: “This work established that ‘woody
    thickening’, where plants in a landscape store more carbon as a result
    of the increased presence of woody species, had occurred in a test site
    in Queensland following the introduction of European land-management
    practices. This work has been extended across the Burdekin catchment to
    evaluate the extent of woody thickening and increased carbon storage.
    Simultaneously, a separate project in NSW has found that the combined
    effects of disturbance (such as by grazing and fire) and increases in
    atmospheric concentrations of carbon dioxide (one of the major drivers
    of the enhanced greenhouse effect) could promote the invasion of
    grasslands by woody plants”.

    AGO’s use of results: The AGO used results from this research to:
    • support the use of lower decomposition rates for wood products in
    landfill in estimates for the National Greenhouse Gas Inventory
    • calibrate a model providing estimates of greenhouse gas emissions and
    carbon stored in wood and wood products for the National Carbon
    Accounting System
    • provide technical guidance to international agencies and support
    Australia’s position in international negotiation on climate change.

    States base accounts on CRC tools: The state agencies were
    particularly interested in the ability to detect woody regrowth using
    RADAR data calibrated with LIDAR, in conjunction with Queensland’s
    existing satellite imagery program.

    Results inserted in education curricula: Two major tools were made available on the web site during the past year:
    • CASS (Carbon Accounting Simulation Software) – a simplified model of
    terrestrial carbon dynamics designed for college and tertiary-level
    education.
    • A modified version of the Range-ASSESS software. Range-ASSESS is a
    map-based tool that allows the user to assess the impacts of various
    grazing and other management scenarios on soil and biomass carbon
    stocks.

    Trees grow 80 x faster after fire: Some of the curious findings of a CRC experiment were:
    • snow gum tree seedlings growing in bare soil under ambient or
    elevated CO2 were, respectively, nearly 50 or 80 times larger than
    seedlings surrounded by grass; and
    • more atmospheric CO2 is likely when phosphorus availability is
    limited (as is typical in Australian soils). It was likely that
    nitrogen inputs would constrain the ability of ecosystems to sequester
    additional carbon to a greater extent than is currently recognised. The
    consequence of this is that atmospheric CO2 concentrations may rise
    more rapidly than expected. Australian soils generally contain low
    phosphorus.

  • US move to promote plug-in cars

    WASHINGTON — A partnership of cities, municipal utilities and
    organizations — including the cities of Los Angeles and Irvine — kicked
    off a national campaign Tuesday urging automakers to build plug-in
    hybrid vehicles.

    This next-generation type of “green” transportation uses an
    additional battery to boost mileage and allows drivers to plug their
    gasoline-electric cars into standard electrical outlets for recharging.

    The technology is designed to appeal to urban commuters who routinely travel relatively short distances in heavy traffic.

    Once charged, the hybrid relies solely on electricity for 25 to 35
    miles or more and can achieve fuel efficiency exceeding 80 miles per
    gallon. That makes the vehicle ideal for city travel, where stop-and-go
    and slow-moving traffic is common.

    “It’s 95% the same car,” said Edward Kjaer of Southern California
    Edison. “You’re just putting a new battery and charger on board.”

    Austin, Texas, will lead the effort by purchasing 600 of the hybrids when they become commercially available.
