Scientists’ open letter to Oakeshott: Burning forests for energy will make climate change worse

Independent MPs Rob Oakeshott and Tony Windsor announced a plan in early February to convince the government to count native forest wood-fired power stations as a renewable energy source. Their plan would mean wood-fired power would qualify for renewable energy subsidies.

Below is an “open letter of concern” to Oakeshott from 16 Australian scientists about his support for “incentives for native forest biomass burning”.

Dear Mr Oakeshott,

Your decision to support incentives for native forest-burning power stations has alarming ramifications for communities and natural ecosystems across Australia.

These include:

• The likelihood that carbon emissions will increase. In many circumstances, forest biomass emits more greenhouse gases than fossil fuels per unit of energy produced.i. Australia’s current accounting rules also mean most logging emissions are not accounted for, hiding real emissions.

• Australia’s forests are some of the most carbon dense on Earth.ii Government policy that encourages the logging and burning of these forests to produce energy will lead to significant carbon emissions that would take centuries to recover.

• Current logging regimes are not ecologically sustainable. The logging of old growth and high conservation value forests and threatened species’ habitats continues in Australia under existing regulatory regimes, and these regimes are demonstrably failing to protect environmental values.iii Biomass harvesting is likely to involve intensified logging and heightened impacts on soil and invertebrate biodiversity and other forest values.iv

• Under the “high value test” covering biomass harvesting, the majority of timber from a logging operation could still be used as feedstock. High value products may form only a small percentage of the volume of timber removed from a logging area, indirectly making biomass the primary beneficiary of harvesting, just as low-value woodchips have historically been the driver for large scale logging.

• Biomass is a dirty fuel. In the United States, leading Medical Societies and health advocacy groups have called for a ban on biomass power plants as they pose an unacceptable risk to the public’s health by increasing air pollution. Burning hundreds of thousands of tonnes of native forest will generate dangerous emissions of nitrogen oxides, particulate matter and sulphur dioxide.v

• Providing renewable energy subsidies to the logging industry will undermine opportunities for the development of clean energy technologies and could decrease funding available to clean energy technologies through the Clean Energy Fund. The cap on Renewable Energy Certificates means native forest burning power stations could displace other, less polluting and damaging forms of renewable electricity.vi

• Australians do not want energy generated from the burning of native forests supplied to their homes.vii Major electricity retailers and the National GreenPower group have also rejected native forest biomass power.viii

Australians overwhelmingly support greater native forest protection.

Mr Oakeshott, we urge you to consider seriously all the evidence and potential consequences related to your disallowance motion. It is our considered opinion that an evidence-based policy in this circumstance would retain the changes as proposed by the Multi-Party Climate Committee.

We urge you to support this sensible policy change and act to safeguard Australian communities and ecosystems.

Yours sincerely,

Biomass Supply and Carbon Accounting for Southeastern Forests

A new study of southeastern forests in the U.S. finds that in the long run, burning wood instead of fossil fuels to make electricity can reduce heat-trapping carbon dioxide in the atmosphere, but not soon enough to prevent worsening the conditions leading to global climate change.

The study also shows that as the industry expands in the Southeast, biomass energy will increasingly come from cutting standing trees instead of using wood residues from sawmills and other sources, emphasizing the need to balance forest ecosystem health and related values, such as drinking water and wildlife habitat, with renewable energy objectives.

Based on current trends in using wood for large-scale power plants and exporting fuel pellets to Europe, biomass energy in the Southeast is projected to produce higher levels of atmospheric carbon for 35 to 50 years compared to fossil fuels. After that, biomass will result in significantly lower atmospheric levels as regrowing forests absorb carbon from previous combustion.

The study, Biomass Supply and Carbon Accounting for Southeastern Forests, was conducted by the Biomass Energy Resource Center in partnership with the Forest Guild and Spatial Informatics Group on behalf of the National Wildlife Federation and the Southern Environmental Law Center, and was funded by a grant from the Doris Duke Charitable Foundation.
