This study analyses what actions Western Australia needs to take to play its role in global and national efforts to limit warming to 1.5°C. It includes a Paris Agreement 1.5°C compatible carbon budget for all sectors of the Western Australian economy, from 2018 to 2050. The report finds that without acting to reduce emissions, Western Australia is likely to use up its Paris-Agreement 1.5°C compatible carbon budget within 12 years, but rapidly reducing carbon pollution will unlock significant economic opportunities for the state.
CO2 emissions pathway for each of the sectors and energy and industry following transformation is consistent with the Paris agreement in each of those sectors. Total CO2 emissions peak around 2020 and decline to about 37% below 2005 levels in 2030, for total budget of around 950 MtCO2. Excluding the LNG industry, energy and industry CO2 emissions would reduce by about 53% by 2030 below 2005 levels, for a total budget of 716 MtCO2.
GHG emissions pathway for each of the sectors following a transformation consistent with the Paris Agreement in each of those sectors. Total GHG emissions peak around 2020 and decline to about 49% below 2005 levels in 2030, reaching net zero around 2050 contingent upon maintaining a large sink in the LULUCF sector. Consistent with national projections, the LULUCF sink is expected to slowly decline from recent high levels due to saturation of reforestation and other activities. It also assumes vegetation conversion (deforestation in broad terms) leading to emissions is effectively halted by 2025, which would require policy intervention. National projections assume ongoing deforestation losses.
This figure shows the historical trajectory of land use, land use change and forestry (LULUCF) drawn from the June 2019 “State and Territory Greenhouse Gas Inventories 2017” for total LULUCF for all greenhouse gases (mainly carbon dioxide) and deforestation (defined as Forest converted to other land uses). A stylised scenario for the future development of the sector is shown assuming deforestation ending by 2025 and the recent uptake of CO2 due to afforestation reforestation and other processes gradually reduces without further policies, essentially following the relative pathway from the December 2018 national greenhouse gas projections for the Australia wide LULUCF sink, maintained at 2030 levels until 2050.
Western Australia’s Fuel Mix for the Paris Agreement Pathway. Solar and Wind energy become dominant sources from the early 2020s. Coal is phased out before 2030, and gas shortly after 2030.
Growth of LNG production capacity and exports until 2019, with projections until 2030 based upon projected changes/increases in LNG production capacity and assuming 95% of nominal capacity is produced and exported. LNG exports in the reference case are limited to 95% of nominal LNG production capacity.
Growth of LNG processing emissions in Western Australia from natural gas used in liquefaction, CO2 from natural gas reservoirs and fugitive emissions from the LNG manufacturing process until 2019 with projections to 2030. Whilst the intensity of CO2 emissions from direct energy use and liquefaction have remained fairly stable, in terms of tonnes of CO2 per tonne of LNG produced, there has been an increase in CO2 vented from natural gas reservoirs due to the concentration of CO2 in more recently exploited natural gas reservoirs. The reference case projection does not include CO2 CCS at the Gorgon LNG plant, however this is included in the Paris Agreement case and explains the drop of total emissions from 2019 to 2020, when it is assumed that the Gorgon CO2 CCS is capturing 80% of the reservoir CO2 and storing it in a secure geological formation.
Relative role of the abatement options described in the text for reference case LNG demand and see Table 6. Zero emissions are not achieved by 2050. The cumulative emissions remaining between 2018 and 2050 after the assumed mitigation options are applied in this reference scenario is 323 MtCO2e. This amounts to approximately one third of the Western Australian Paris agreement compatible carbon budget for the energy system. There could be more or less emissions left depending upon the rate and scale of the actual mitigation options deployed.
Relative role of different elements of a Paris Agreement LNG demand reduction scenario and mitigation options in reducing emissions from the reference case to close to zero emissions by 2050. The cumulative emissions remaining between 2018 and 2050 after the assumed mitigation options are applied un this Paris Agreement LNG demand scenario is 274 MtCO2e. This amounts to approximately about 29% of the Western Australian Paris agreement compatible carbon budget for the energy system. There could be more or less emissions left depending upon the rate and scale of the actual mitigation options deployed.
Unabated: the Carbon Capture and Storage 86 billion tonne carbon bomb aimed at derailing a fossil phase out
The climate talks at COP28 have centred around the need for a fossil fuel phase out. Our analysis quantifies the risk posed by restricting a phase out commitment to only ‘unabated’ fossil fuels.
No change to warming as fossil fuel endgame brings focus onto false solutions
The CAT's annual warming estimate has risen by 0.1˚C to 2.5˚C. The estimate is largely influenced by weak existing targets rather than shifts triggered by updated Nationally Determined Contributions.
When will global greenhouse gas emissions peak?
The IPCC says peaking before 2025 is a critical step to keep the 1.5°C limit within reach. With emissions set to rise in 2023, this leaves limited time to act. To assess if we can meet this milestone, we look at when global emissions might peak, as well as what we can do to get there in time.
Wind and solar benchmarks for a 1.5°C world
This report presents a detailed methodology for determining the amount of wind and solar capacity that is required for a country to align with the Paris Agreement’s 1.5°C temperature goal. While the focus of the report is the method, it includes illustrative benchmarks for Brazil, China, India, Indonesia, Germany, South Africa.
A 1.5°C future is possible: getting fossil fuels out of the Philippine power sector
The Philippines is also one of the fastest-growing developing countries: poverty is in decline, access to energy is rising and, with that, demand for energy services. However, fossil fuels still dominate the energy system, accounting for 78% of power generation in 2022. This report sets out what the Philippines government needs to do to get the country’s power sector onto a 1.5˚C compatible emissions pathway, replacing fossil fuels with renewable energy.
Production Gap Report 2023
Governments, in aggregate, still plan to produce more than double the amount of fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C. The persistence of the global production gap puts a well-managed and equitable energy transition at risk.
Emissions impossible: Unpacking CSIRO GISERA Beetaloo Middle Arm fossil gas emissions estimates
This report provides an independent evaluation of the CSIRO and GISERA assessments of the potential greenhouse gas emissions that would result from the exploitation of the Beetaloo fossil shale gas reserves.
Adjusting 1.5°C climate change mitigation pathways in light of adverse new information
This study uses an integrated assessment model to explore how 1.5°C pathways could adjust in light of new adverse information, such as a reduced 1.5°C carbon budget, or slower-than-expected low-carbon technology deployment.
