In 2014 the NSW Department of Planning and Environment’s Building Sustainability Index (BASIX) system was revised to set a lower greenhouse gas emission rating for residential wood-fire heating.
Research conducted by the CSIRO found that firewood produces less greenhouse gas than all other domestic heating options. CSIRO’s finding was backed by accepted national and international protocols for assessing greenhouse gas emissions from biomass, confirming that wood forms a natural part of the cycle for carbon and therefore is considered renewable.
The Australian Standards for wood heaters AS/NZS4012&4013 were reviewed in 2019 seeing a further reduction of 40% lowering the level to just 1.5g/kg as well as raising the efficiency to 60% minimum.
This means within the next 5 years emission levels for all new wood fires will be reduced by over 60% on current levels.
This has required industry to redesign and retest their entire range of available models.
These changes will see Australia providing one of the most stringent Standards for hardwood fuelled wood heating appliances in the world.
