Meat & Livestock Australia says its latest research by CSIRO shows the Australian red meat and livestock industry has reduced its net greenhouse gas (GHG) emissions by 78 per cent since 2005.
The CSIRO report updates the estimated emissions attributable to the production and processing of beef, sheep and goats based on the 2021 Australian National Greenhouse Gas Inventory.
It found that in 2021, net greenhouse gas emissions from the red meat industry were 31 Mt CO2-equivalent, representing a 78 per cent decrease compared to the reference year of 2005.
MLA Carbon Neutral 2030 (CN30) project manager, Julia Waite, said the reduction was primarily due to impacts in the land use sector.
“Low rates of clearing and greater volumes of regrowth have contributed to a larger pool of carbon on land associated with livestock management, bringing down the collective position of the sector,” Waite said.
“The contribution from land use change was particularly significant between 2020 and 2021 due to high rainfall, which was 9 per cent above the historical average, and conditions favourable for vegetation growth during La-Niña.
“The contrast is especially stark given the previous two reporting years were marred by drought and bushfires.
“Given the variability of the Australian climate, we anticipate sequestration volumes will retract when conditions trend back towards drier El Nino,” Waite said.
She said the annual emissions reports by MLA continued to be informed by the best available science and nationally maintained data. The latest report revises historical emissions, as more accurate data and methods have been adopted into the National Greenhouse Gas Inventory.
Emissions are attributed to the red meat industry based on animal numbers, feed intake, livestock processed, and resource use, which have been part of the industry’s work in annually benchmarking its GHG footprint since 2015.
The largest proportion of direct emissions from red meat is enteric methane produced by grazing beef cattle. These emissions have remained stable in recent years.
Sequestration attributable to the red meat sector is estimated from FullCAM which uses satellite imagery to account for change in Australia’s landscape.
Waite said that while the trajectory was positive since 2005, MLA recognised the broader expectation for direct emissions reduction while maintaining production of high-quality protein. This is supported by investment in research and development, and initiatives to support Australian red meat producers to adopt practices that provide a win-win for business and the environment.
“In the short to medium term, sequestration helps to balance the ledger while the private and public sector continues to invest in options for direct emissions reduction.
“Increasing production and resource efficiency, use of renewable energy, and manure management are the primary tools at our disposal today to lower emissions of livestock production.
“Novel interventions like low methane pastures, supplements, and genetic indexes are likely to play a bigger role in the later part of the decade, provided they are commercially viable with co-benefits for the whole farm business.
“Over time this can reduce the reliance on sequestration,” she said.
Since 2017, Meat and Livestock Australia has co-invested $152 million in R&D and extension to support net emissions reduction of the red meat supply chain.
In 2017 the Australian red meat industry committed to achieving carbon neutrality by 2030 (CN30). The CN30 target definition is Net zero greenhouse gas emissions by 2030.
