Offsets required to reduce the carbon balance of sheep and beef farms through carbon sequestration in trees and soils.

Jigsaw Farms was net zero between 2010 and 2017.

“The study by Doran-Browne et al. (2018), and sequestration data from this study estimate that Jigsaw Farms was net zero between 2010 and 2017 (shaded in Table 1).”

A previous assessment in 2018 estimated that Hensley Park achieved zero net emissions between 2010 and 2014.

“A previous assessment in 2018 estimated that the Hensley Park property achieved zero net emissions between 2010 and 2014 (Doran-Browne et al. 2018).”

The previous carbon assessment (Doran-Browne et al. 2018) for the property was for the Hensley park property only.

“The previous carbon assessment (Doran-Browne et al. 2018) for the property was for the Hensley park property only.”

The emissions from the enterprise and the emissions intensity of beef, sheep meat and wool were calculated using the sheep and beef greenhouse accounting framework tool (SB-GAFv2.3).

“The emissions from the enterprise and the emissions intensity of beef, sheep meat and wool were calculated using the sheep and beef greenhouse accounting framework tool (SB-GAFv2.3)(Doran-Browne et al. 2018).”

On average, livestock emissions and sequestration were respectively 2.6 and 1.6 times lower in Doran-Browne et al. (2018) than calculated in the current assessment.

“A comparison indicates that on average, livestock emissions and sequestration were respectively 2.6 and 1.6 times lower in Doran-Browne et al. (2018), than calculated in the current assessment (Table 1).”

In Doran-Browne et al. (2018), total gross emissions ranged from 2336 t CO2-e in 2000 to a maximum of 8520 t CO2-e in 2006, declining to 4805 t CO2-e in 2014.

“which ranged from 2336 t CO 2 -e in 2000,”

Total gross emissions in the current assessment were higher than those in Doran-Browne et al. (2018).

“Total gross emissions were higher than the assessment by Doran-Browne et al. (2018), which ranged from 2336 t CO 2 -e in 2000,”

The previous assessment indicated that livestock and farm practice emissions would exceed annual rates of carbon sequestration from 2017 onwards.

“This assessment indicated that soil and tree sequestration rates would decline over time as soil carbon reached maximum potential and tree growth rates slowed, and that livestock and farm practice emissions would exceed annual rates of carbon sequestration from 2017 onwards.”

In the previous assessment, Hensley Park was calculated to have achieved net zero between 2010 and 2014.

“In the previous assessment, Hensley Park was calculated to have achieved net zero between 2010 and 2014 (Table 1) (Doran-Browne et al. 2018).”

Estimated tree carbon sequestration in the current assessment is higher than previous modelling by Doran-Browne et al. (2018).

“Estimated tree carbon sequestration is also higher than previous modelling by Doran-Browne et al. (2018), where tree sequestration was estimated at -37,003 t CO 2 -e from 2000 to 2014, with a peak of -5104 t CO 2 -e in 2011 Table 1).”
