50% reduction in scope 1&2 emissions and 25% reduction in scope 3 emissions by 2032 (on a 2017 base year) Origin’s current medium-term emission reduction targets have been approved by the SBTi. We have committed to halve our Scope 1 and Scope 2 greenhouse gas emissions on an equity share basis by 2032, from our FY2017 baseline of 18,246 kilotonnes (kt) CO2-e. Emissions reported on an equity basis captures the emissions relating to the assets we own, including our generation fleet and our 37.5 per cent share of Australia Pacific LNG, which includes the downstream operations and non-operated areas. We have also committed to reducing Scope 3 emissions by 25 per cent by 2032 from the FY2017 baseline of 27,451 kt CO2-e. Our SBTi Scope 3 target covers a minimum two-thirds of our total Scope 3 equity emissions in the baseline. This Scope 3 target covers all supply chain emissions incurred within the domestic market, including the electricity and gas that our Energy Markets business sells to customers and the Origin equity gas Australia Pacific LNG sells to domestic customers. It does not include Australia Pacific LNG’s LNG exports.

Our total Scope 3 emissions reported under our SBTi-approved emissions reduction target increased by four per cent in FY2021 to 22,347 kt CO2-e, and were 19 per cent lower than our FY2017 baseline, largely reflecting lower output from our owned and contracted generation resulting in an increase in net electricity purchases from the NEM and external sources, partly offset by a reduction in domestic gas sales at Australia Pacific LNG primarily due to the roll off of legacy contracts. Further details are provided in the following section. The world is rapidly accelerating towards a lower-emissions future, and we will play an important role in that transition. We will help bring to bear the energy and technologies needed to meet decarbonisation goals, not just for the energy sector, but also for other sectors across the economy. We are progressing the decarbonisation of our business. In 2017, we became the first company in Australia to set science-based emissions targets independently approved by the Science-Based Target initiative (SBTi). Our medium-term, SBTi-approved targets cover Scope 1, Scope 2 and Scope 312 emissions. One of the ways we will achieve our targets is by exiting coal-fired generation by 2032 or earlier. We continue to progress work on updating our existing emissions r
