Australia’s 2030 Target Gap and the Role of LULUCF: An IPAT Analysis

Under the 2016 Paris Agreement, Australia committed to reducing emissions to 43% below 2005 levels by 2030 and aims to be net zero (including LULUCF) by 2050.This commitment is part of the global effort to limit warming to below 2°C (Department of Climate Change, Energy, the Environment and Water, 2025).This short commentary applies the IPAT model to assess how population, affluence, and carbon intensity drive GHG impacts.Australia celebrated 26 years of uninterrupted economic growth from 1991 to 2017 (Leal et al., 2019), reflected in rising affluence.However, it is a country with extensive non-renewable resources such as coal, oil, and natural gas (Leal et al., 2019).The electricity sector is the largest emitter, with coal accounting for roughly two-thirds of all electricity generation, resulting in Australia having the highest CO2 emissions per capita in 2019 (OECD, 2019).Additionally, Australian CO2 emissions account for 1.33% of total global emissions, with 0.97% originating from the electricity sector (Ahmed et al., 2021).As the largest emitter, the electricity sector significantly drives overall GHG growth.Historical trends presented in Table 1 from 1970-2023 show a 1.12% average annual growth (AAG) in total GHG emissions, a 1.43% AAG in population, a 1.57% AAG in GDP per capita, and a -1.87%AAG in Carbon intensity.A negative carbon intensity growth rate means
