The report examines the impact of transitioning from state-based average emissions factors (Method 1) to site-specific estimates (Method 2) for fugitive methane emissions in Australian open-cut coal mines. It finds that this accounting shift has consistently decreased reported emissions by 65–70% according to Reputex, with a particularly stark effect in New South Wales, where reported fugitive emissions intensity is six times lower than the state-based factor.

Underground coal mine closures have been the primary driver of fugitive emissions reductions in Australia's coal sector, as a small number of 'super-emitting' mines contribute a disproportionate share of total emissions. While strategic investments in methane capture have helped, most reductions resulted from the closure of older mines or safety-related shutdowns. However, the document warns that 27 proposed projects and recent license extensions, such as for the Narrabri mine, threaten to undermine national and state climate targets.

Australia's coal production grew by 170% between 1990 and 2022, yet fugitive emissions increased by only 0.17%. This trend is driven by the closure of high-emitting underground mines and a transition toward open-cut mining, which relies on estimated rather than measured emissions. The report highlights a concerning shift toward site-specific emissions reporting (Method 2), which has significantly lowered reported emissions in New South Wales compared to state-based averages. While underground mine closures have provided historic emissions wins, new project expansions and extensions threaten to reverse these gains.

The report argues that Australia is a 'fossil fuel behemoth' whose exported emissions are projected to be 3.3 times larger than its domestic emissions within five years. It highlights that despite IEA warnings against new developments, Australia has approved 30 new coal and gas projects since 2021. The document asserts that a conservative selection of planned projects could consume 6.2% of the remaining global 1.5°C carbon budget. It further criticizes the Australian Safeguard Mechanism as insufficient because it does not manage exported emissions or prevent new project approvals. Finally, it contrasts Australia's fossil fuel expansion with its public commitments to Pacific nations and its bid to co-host COP31.

Ember argues that the Boggabri coal mine's fugitive emissions are severely under-reported, using a self-led estimate that is 95 times lower than NSW state guidance. The submission warns that the proposed Modification 10, which involves mining deeper coal seams between 2033 and 2040, could result in Scope 1 emissions being 9 million tonnes higher than reported if state-recommended factors were used. Ember highlights a lack of assessment regarding how increased mining depth affects methane release and calls for a peer-reviewed assessment of pre-mine drainage mitigation before approval.

The report argues that a proposed shift toward unverified company-led emissions reporting (Method 2) in Australian open-cut coal mines allows operators to significantly understate their climate impact. By analyzing eight operating and two proposed mines, Ember finds that some company-led estimates are up to 135 times lower than state-based averages, leading to the 'erasure' of millions of tonnes of CO2-e from national inventories. The document criticizes the Australian government for proposing to expand this self-reporting regime without implementing the Climate Change Authority's recommendations for mandatory top-down verification and increased transparency.

Ember's submission to the NSW Parliament inquiry into Net Zero highlights that the coal mining sector is the biggest potential risk to the state's emission goals. The document argues that existing federal mechanisms, such as the Safeguard Mechanism and the Coal Mine Waste Gas method, are insufficient to drive material onsite reductions. Using Tahmoor Colliery as a case study, Ember demonstrates that Ventilation Air Methane (VAM) mitigation via Regenerative Thermal Oxidiser (RTO) technology is technically and commercially feasible but underutilised due to a lack of state-led regulatory pressure and the availability of carbon offsets. The submission calls for a pause on new coal mine expansions and a dedicated report from the Net Zero Commission by June 2025 to assess sectoral risks and develop a coal-specific emissions target.

The document provides a submission to the Federal Department of Climate Change, Energy, the Environment and Water (DCCEEW) regarding the review of the Coal Mine Waste Gas (CMWG) method. Ember argues that the CMWG method is a critical supplementary incentive for decarbonising the resource sector, particularly for metallurgical coal, and should be extended beyond 2025. The submission specifically advocates for expanding the method's eligibility to include open cut mines, as current regulatory frameworks like the Safeguard Mechanism may perversely reward lower-emitting open cut mines. Ember also suggests improving measurement and verification by moving away from state-based emissions factors toward site-specific measurements and top-down verification. Additionally, the document proposes that the CMWG could help manage increasing electricity demand in the mining sector by using waste gas to 'firm' renewable energy output and could potentially incentivise the mitigation of abandoned mine methane.

Ember's analysis indicates that Whitehaven Coal Limited could release over 1.2 million tonnes of methane by 2050, with emissions potentially doubling by 2030 due to planned expansions. The report highlights severe discrepancies in reporting, noting that the Narrabri mine's actual emissions have been nearly five times higher than final EIS estimates. Ember argues that Whitehaven's use of internal emission factors for open-cut mines—which are often significantly lower than Australian averages—leads to underreporting. The report recommends third-party verification, improved transparency, and a 75% reduction in portfolio-wide methane emissions by 2030 to align with 1.5 degree pathways.

The document categorizes plastics-related instruments into government legislation, voluntary multistakeholder standards, and non-governmental initiatives. It identifies significant gaps in standards for upstream production and reuse systems, while noting a concentration of existing efforts in waste management. The authors argue for enhanced international cooperation to reduce regulatory fragmentation and improve inclusivity for developing countries, suggesting that a future global plastics treaty could drive the development of harmonized design and transparency standards.

Ember argues that approving 15 reconsidered coal projects would increase Australia's annual coal mine methane emissions by approximately 190 thousand tonnes. The organization emphasizes that meeting the 1.5C warming limit requires a 75% reduction in energy sector methane emissions by 2030, which cannot be achieved through mitigation technology alone without reducing coal production. Ember specifically recommends closing the gassiest thermal coal mines and avoiding new thermal coal mines, while suggesting that metallurgical coal mines only be approved if they employ available mitigation technologies and cooperate with the UNEP’s International Methane Emissions Observatory.

The document argues that coal mine methane (CMM) is a critical but underreported driver of emissions in New South Wales, accounting for over 90% of the state's energy sector methane emissions. Ember proposes two new pillars for the NSW EPA's Action Plan: 'Inform and Plan' and 'Mitigate'. The 'Inform and Plan' pillar suggests collaborating with international initiatives like the International Methane Emissions Observatory and implementing high-tier IPCC measurement, reporting, and verification (MRV) methodologies to address reporting gaps. The 'Mitigate' pillar recommends a 75% reduction target for methane emissions by 2030, the closure of 'gassy' thermal coal mines, and a commitment to no new coal mines or expansions. The report highlights that current reporting may be significantly underestimated, citing IEA estimates that Australia's reported CMM emissions could be missing 800 thousand tonnes.

Australia could reduce its annual methane emissions by 18% by 2030 by focusing on coal mine methane (CMM) mitigation. The report argues that CMM is one of the cheapest and fastest sources of methane to mitigate, costing approximately $270 AUD per tonne of methane, which is four times cheaper than agricultural mitigation. Key recommendations include phasing out thermal coal mines by 2030, preventing new coal mine expansions, and implementing technical solutions like ventilation air methane (VAM) capture and extensive drainage. The report also warns that current reporting is likely underestimated, citing the IEA's estimate that 800 thousand tonnes of methane are missing from reported figures.

Australia's coal mines are a major source of methane, with evidence suggesting official reports significantly underestimate the actual emissions. The report highlights that a small number of 'super-emitter' mines contribute a disproportionate amount of emissions and warns that proposed new coal projects will further increase these levels. It advocates for a transition to direct measurement over emission factors, the adoption of ventilation air methane (VAM) abatement technologies, and the phasing out of coal, particularly the gassiest mines, to meet climate targets.

Australia has become a global leader in decarbonizing high-end commercial buildings through 'ambition loops'—positive feedback cycles where government regulation, industry collaboration, and market demand reinforce each other. Early leadership from the Victoria state government and the Australian Sustainable Built Environment Council (ASBEC) helped overcome initial knowledge gaps and lack of demand. The implementation of mandatory efficiency codes and transparency tools, such as the Commercial Building Disclosure Program and the National Australian Built Environment Rating System (NABERS), created a competitive environment where sustainable buildings attract more corporate tenants and investors. This model has since influenced residential and construction sectors in Australia and exported rating systems to New Zealand and the UK.

The WWF Australian Wildlife & Nature Recovery Fund raised $50 million to address the catastrophic 2019-2020 bushfires, which burned over 29 million acres of forest and killed or displaced nearly 3 billion animals. The fund's activities were divided into three phases: immediate emergency response (Phase I), landscape restoration and protection (Phase II), and long-term societal future-proofing (Phase III). Key investments included $10 million for Indigenous engagement to incorporate traditional fire management, $9 million for species recovery and adaptation, and $8 million to stabilize climate change. Specific projects included the deployment of seed drones to restore koala habitats, the establishment of a wildlife hospital in the Northern Rivers region of New South Wales, and the development of fire-resistant nest boxes for the greater glider. The fund's work has transitioned into a five-year comprehensive campaign called 'Regenerate Australia' to mitigate future climate events.

The document details the establishment of the Mine Audits Unit and the role of the Chief Auditor in British Columbia, created to ensure independent, transparent evaluation of the provincial mining regulatory framework. This initiative followed the 2014 Mount Polley tailings storage facility breach and a 2016 Auditor General report that found compliance and enforcement activities were inadequate. The first major audit focused on Tailings Storage Facilities (TSFs), concluding that 2016 Code revisions have had positive impacts but identifying seven recommendations for improvement, including resolving inconsistencies with the Water Sustainability Act and clarifying ambiguous language. The Ministry has accepted these recommendations and established a Strategy and Advisory Services Team to implement them.

The 'Warming Up' project leverages Australia's community radio sector to document and amplify local experiences of climate change, focusing on marginalized communities like the Barkindji people in Wilcannia. By providing training and resources for participatory audio production, the project seeks to bridge the gap between remote regional experiences and urban decision-makers.

The document examines a landmark Australian Federal Court ruling where Justice Mordecai Bromberg found that the Federal Environment Minister owes a duty of care to young people to protect them from the climate crisis. While the court did not grant an injunction against the expansion of the Vickery coal mine, the ruling establishes a precedent for climate-based litigation under the law of negligence and requires the government to consider the impacts of climate change on youth when approving fossil fuel projects.

The report examines the mechanisms used to ensure mining companies provide sufficient funds for environmental rehabilitation if they fail to meet closure obligations. It details various financial instruments, cost estimation methodologies, and policy requirements from leading jurisdictions including Australia, Canada, Germany, South Africa, and the United States.
