Reducing coal mine methane (CMM) emissions is presented as a critical, low-cost opportunity to avoid 0.2C of warming by 2050 and prevent over 180,000 premature deaths annually by 2030. While the IEA and UNEP estimate that between 54% and 63% of global CMM emissions can be mitigated by 2030, current action is negligible, with only 130 of 1,800 active mines reporting mitigation projects. The most cost-effective methods include drainage systems, where 62% of the 7,460 kilotonnes of abatement potential is available at negative net cost, and ventilation air methane (VAM) oxidation, which could reduce emissions by 23.7% with a $2.5 billion USD investment.

Satellite observations of methane plumes from coal mines increased by approximately 1,400% between 2019 and 2024, yet a significant gap remains between theoretical detectability and actual monitoring. While 71% of global coal production is located in regions with favourable conditions for detection, only 10% of hard coal production has been observed via satellite. This discrepancy is attributed to factors such as satellite overpass frequency and instrument tasking priorities. High detection rates in Canada and Poland are linked to regional prioritisation by Carbon Mapper and regulatory scrutiny under the EU Methane Regulation, whereas major producers like India, South Africa, and Australia show substantial monitoring gaps despite favourable geography.

Global coal mine methane (CMM) emissions remained broadly steady at 34.7 million tonnes in 2023, despite an 8% increase in global coal production since 2021. This trend undermines the Global Methane Pledge's goal to cut anthropogenic methane emissions by 30% by 2030. Analysis reveals significant data gaps, as six of the nine largest emitters failed to submit official 2023 CMM data to the UNFCCC. Independent estimates from the IEA, GEM, and satellite data often diverge sharply from official figures, particularly in South Africa, Indonesia, and Russia, suggesting widespread underreporting and a reliance on outdated emission factors rather than mine-level measurements.

Coal mine methane (CMM) emissions remained steady at approximately 34.7 million tonnes in 2023 despite rising coal production, indicating a failure to align with the Global Methane Pledge. The report highlights a critical data gap, estimating that 89% of emissions were unreported to the UNFCCC in 2023 and that 87% of global production relies on generic emission factors rather than direct measurement. While satellite monitoring is increasing, it currently captures only 10% of hard coal production. Technically, 54-63% of CMM emissions could be mitigated by 2030 using proven technologies, with drainage station capture offering significant potential at negative net cost and ventilation air methane (VAM) oxidation capable of cutting nearly a quarter of emissions.

The document details the technical processes Ember uses to track coal mine methane (CMM) emissions, including how it fills historical data gaps using emission intensity factors and forecasts future emissions based on IEA production data. It outlines a confidence scoring system (0-6) for national reporting based on recency, similarity to independent estimates, and methodology robustness. Additionally, it explains how Ember calculates the proportion of surface versus underground mining and the percentage of hard coal production associated with satellite-detected methane plumes.

The report highlights significant gaps and uncertainties in global coal mine methane (CMM) emissions reporting, noting that 89% of emissions were left unreported in 2023. It criticizes the reliance on generic emission factors (Tiers 1 and 2) used for 87% of global coal production and advocates for the transition to direct, facility-level measurements (Tier 3) to increase data confidence and support mitigation policies.

Ember recommends that governments mandate direct measurement and reporting for all coal mines, integrating satellite and independent data to identify super-emitters. The report advocates for banning venting from drainage systems, implementing binding reduction requirements for large emitters, and creating incentive mechanisms for ventilation air methane (VAM) mitigation. It further emphasizes the necessity of phasing down coal use and requiring comprehensive mine-closure plans to prevent ongoing emissions from decommissioned sites.

The report finds that by 2025, fossil fuel power generation fell below its peak in all 38 OECD member countries, driven by the rapid scaling of solar and wind energy. This trend is extending to emerging markets, with 2025 marking the first year this century (excluding 2020) that non-OECD fossil generation fell, specifically in China and India. The transition is increasingly driven by economic imperatives, as the levelized cost of solar and onshore wind is now 60% lower than combined cycle gas turbines.

In 2025, global electricity generation reached a historic milestone as renewables overtook coal power for the first time in 100 years, accounting for 33.8% of the global mix. This shift was driven by a record increase in solar power generation (636 TWh), which alone met 75% of the global electricity demand growth. Consequently, global fossil generation saw a slight decline of 38 TWh, marking the first such decrease since 2020 outside of a global recession or exceptionally mild year. This trend was most prominent in China and India, where fossil generation fell for the first time simultaneously in the 21st century. While Asia remains the only region where coal still exceeds renewables, the global emissions intensity of electricity fell to 458 gCO2e per kilowatt hour in 2025.

In 2025, clean power met all global electricity demand growth for the first time since the pandemic, as China's fossil generation plateaued. Solar power is the primary driver of this shift, and the deployment of battery storage is increasingly enabling solar to displace fossil fuels during non-daylight hours. India is expected to follow a less coal-reliant path than China due to lower energy intensity and the maturity of low-cost clean technologies.

In 2025, global electricity generation saw a significant shift toward low-carbon sources, with solar and wind reaching a combined 17.3% share of total generation. Solar was the fastest-growing source, adding 636 TWh and meeting 75% of global demand growth. Conversely, coal's share of global electricity fell below one-third for the first time on record to 33.0%, and renewable generation exceeded coal generation for the first time. Low-carbon sources (including nuclear) reached 42.6% of total generation, while the emissions intensity of electricity dropped by 2.7% in 2025, the largest annual decline in two decades.

The report provides a detailed analysis of the power sectors of seven major countries and regions in 2025, which collectively represent 72% of global electricity demand. Key trends include China's unprecedented solar growth and first absolute decline in power sector emissions since 2015, the US seeing wind and solar overtake nuclear power for the first time, and the EU's wind and solar generation exceeding fossil generation. India saw renewable growth double its demand increase, while Brazil maintained one of the cleanest systems globally with 87% renewable generation. Conversely, Russia and Japan continue to rely heavily on fossil fuels, with Russia's wind and solar remaining marginal at less than 1% of its mix.

In 2025, global electricity demand grew by 2.8% (849 TWh), all of which was met by low-carbon power generation, leading to a 0.2% decline in fossil fuel generation. Solar power was the primary driver, increasing by a record 636 TWh (30%) and meeting 75% of the net demand increase. For the first time in the modern era, renewables (33.8%) overtook coal (33.0%) in the global electricity mix. This shift was led by China and India, both of which saw declines in fossil generation in 2025. Additionally, battery storage is scaling rapidly, with costs falling 45% in 2025, enabling the shift of daytime solar generation to other hours.

Drax biomass power station received record public subsidies of £999 million in 2025, costing UK households approximately £13 each per year. These payments are expected to drop by about half to £460 million per year starting in 2027 as the Renewables Obligation scheme ends. Despite the subsidy reduction, Drax is projected to remain the UK's largest carbon emitter until at least 2030, while its long-term plans for carbon capture technology remain uncertain.

The report analyzes the 'twin fossil shocks' of the 2020s—the 2022 Russian invasion of Ukraine and the 2026 shutdown of the Strait of Hormuz—comparing them to the 1970s oil crises. It contends that unlike the 1970s, today's energy transition is driven by 'electrotech' (solar, wind, batteries, and EVs) that is cheaper, faster to deploy, and more secure than fossil fuels. The authors suggest these shocks will accelerate the absolute peak of fossil fuel demand, particularly by pushing LNG out of power generation and oil out of road transport, especially in Asia. The document concludes with policy recommendations to prioritize electrification and remove fossil fuel subsidies to end fuel dependency.

The report analyzes the role of renewable energy in shielding Britain from a fossil fuel crisis in March 2026. It finds that new wind and solar capacity reduced gas-fired power generation by 39% compared to 2021, avoiding approximately £7 million in daily gas purchases during the first four weeks of the crisis.

Drought in Türkiye has led to a permanent decline in hydroelectric output, with the average capacity factor of plants falling from 38% (1996–2005) to 26% over the last decade. This decline is compensated by natural gas power plants, increasing the country's reliance on energy imports. The long-term impact of drought on energy imports is estimated at an average of $1.8 billion per year, with the three largest dams alone (Atatürk, Karakaya, and Keban) contributing to $400 million in additional annual gas imports.

Turkey experienced record growth in wind and solar energy capacity in 2025, with combined new installations reaching 6.5 GW and total installed capacity for both sources hitting approximately 40 GW. Solar electricity generation doubled between 2023 and 2025, rising from 18.4 TWh to 37.3 TWh. While Turkey leads in its immediate region, its overall renewable energy share of electricity production (43% in 2025) remains below the European Union average of 48%.

Turkey needs to commission 8 GW of new wind and solar capacity annually to meet its 2035 goals, requiring an estimated $28 billion in additional grid investment. The report identifies critical bottlenecks in grid connection capacity, particularly for unlicensed and storage-based projects, and suggests accelerating permitting through the 2025 "super permit" legislation. It recommends diversifying energy sources via floating solar and offshore wind, leveraging hybrid solar installations at hydroelectric plants to mitigate drought risks, and increasing regional interconnection capacity to enhance grid flexibility. Additionally, it argues that the $8.7 billion purchase guarantee for domestic coal plants contradicts renewable goals and complicates system management.

The report finds that drought has caused a permanent decline in Turkey's hydroelectric capacity factors, leading to a reliance on natural gas to compensate for the loss, which increases energy imports by an estimated 1.8 billion dollars annually.
