The Asia Data Transparency Report 2023 finds that over half of the surveyed Asian economies have poor or insufficient power sector data transparency, affecting the electricity needs of 684 million people. While high-income economies generally score better, some lower-middle income nations like India, Bangladesh, and Sri Lanka are demonstrating good practice. The report emphasizes that granular, real-time, and open-access data is essential for grid optimization and evidence-based policymaking to meet decarbonisation targets. It highlights a successful public-private partnership in India between NITI Aayog and the Vasudha Foundation and provides nine practical recommendations for improving data governance, including the use of machine-readable formats and unique identifiers.

Ember submits that Method 1 for estimating methane emissions from Queensland open cut coal mines is inadequate because it relies on State-based averages that ignore spatial and temporal variability and disguise 'super emitters'. The document recommends phasing out Method 1 in favor of a multi-input measurement model combining geotechnical cores, drones, fixed monitoring, and satellite verification to ensure accurate reporting and support Australia's climate targets.

The EU power system successfully navigated the 2022-2023 winter without a return to coal, as record renewable generation and significant electricity demand reductions—driven by emergency legislation, high prices, and mild weather—led to renewables providing a higher share of electricity than fossil fuels for the first time in a winter period.

In 2022, solar and wind power continued their rapid growth, with solar being the fastest-growing source and wind recording the largest absolute increase. Conversely, nuclear power saw a significant decline, primarily driven by outages in France and Germany. Coal generation reached an all-time record high of 10,186 TWh, although its overall share of the global electricity mix slightly decreased. Hydro power rebounded after a poor 2021 but remains below 2020 levels due to droughts in Europe. Fossil gas generation remained relatively stable despite supply chain disruptions. To align with the IEA Net Zero Emissions scenario by 2030, the report argues that solar and wind must sustain high annual growth rates, coal and unabated gas must be phased out, and nuclear power must grow more rapidly than its recent historical average.

The global electricity sector is the largest CO2 emitter and must reach net zero by 2040 to facilitate the decarbonisation of other sectors. Following the IEA Net Zero Emissions (NZE) scenario, wind and solar are identified as the primary drivers of this transition. By 2030, wind and solar must increase to 41% of global electricity generation, while coal and gas generation must decrease by 54% and 24% respectively. By 2040, unabated coal must be phased out globally, and unabated gas should provide only 0.3% of electricity. This transition is essential to support rising electricity demand in developing regions and the electrification of transport, heating, and industry.

A foreword by Chile's Minister of Energy, Diego Pardow, for the Global Electricity Review 2023, highlighting the economic benefits of electromobility and Chile's progress in renewable energy generation.

In 2022, global electricity generation remained dominated by fossil fuels at 61%, though wind and solar reached a record 12% share. Despite record growth in renewables, global power sector emissions hit an all-time high of 12,431 mtCO2, driven by rising demand in major economies like China and India. The report highlights a gap between current trends and the IEA Net Zero Emissions scenario, which requires a rapid phase-out of unabated coal and gas by 2035-2040.

In 2022, China's power demand grew by 4.4% (374 TWh), with wind and solar generation increasing by 26% to meet 69% of the net demand increase. Despite this clean energy growth, coal generation reached an all-time high in absolute terms (5,420 TWh), though its share of the electricity mix fell to 61%. Since 2000, China's total power sector emissions have increased fivefold to 4,694 MtCO2, even as emissions intensity declined by 21%. To reach a net zero power sector by 2040, China would need to reduce emissions by 261 million tonnes of CO2 annually.

In 2022, global electricity reached its lowest emissions intensity ever at 436 gCO2/kWh, with wind and solar hitting a record 12% of generation. Despite this, total power sector CO2 emissions reached a record high of 12,431 mtCO2 because wind and solar growth could not fully keep pace with a 2.5% increase in global electricity demand. This gap was filled by coal and other fossils, with coal generation rising by 108 TWh to a record 10,186 TWh. While clean electricity sources other than wind and solar saw their first year-on-year decline since 2011 due to nuclear outages and droughts, 2022 is characterized as an 'accelerator year' due to policy shifts like the EU's REPowerEU and the US Inflation Reduction Act.

The global electricity system is transitioning toward clean energy, with wind and solar emerging as dominant forces. In 2022, wind and solar met 80% of the increase in global electricity demand. However, other clean sources like nuclear and hydro are underperforming relative to 1.5°C pathways. The report predicts a structural tipping point as soon as 2023, where clean power growth may finally exceed total electricity demand growth, leading to an enduring decline in fossil fuel generation. While coal plant closures have slowed, particularly in China and India, the report suggests a simultaneous phasedown of both coal and gas power is becoming likely, especially in G7 countries and Asia due to energy security and cost concerns.

The report analyzes Türkiye's shift in renewable energy generation from the hydro-rich east to the wind and solar-rich west and center. It highlights the vulnerability of the energy system to droughts, which historically force a reliance on imported gas. While Konya has seen massive solar growth due to the Karapınar plant, other high-potential southern provinces like Antalya and Van remain underutilized. The report advocates for more ambitious wind and solar targets to ensure energy security and meet net-zero goals.

In 2022, wind and solar reached a record 12% share of global electricity, driving carbon intensity to a record low of 436 gCO2/kWh. However, absolute power sector emissions reached an all-time high of 12,431 mtCO2 because clean power growth did not fully meet rising global demand, which grew by 2.5% (+694 TWh). While coal generation rose by 1.1% to a record 10,186 TWh, the report forecasts that 2023 could be the first year of structural decline in fossil generation and the peak for power sector emissions. The analysis highlights a significant gap between current growth and the IEA NZE pathway, which requires wind and solar to reach 41% of global generation by 2030.

In 2022, solar and wind energy accounted for 92% of India's new power generation capacity, totaling 15.7 GW, while coal additions dropped by 78% compared to 2021. Solar energy was the primary driver, adding 13.9 GW in a single year. Rajasthan and Gujarat emerged as the leading states, together contributing 8.6 GW of solar capacity and accounting for one-third of India's national 2030 renewable energy capacity target of 450 GW. Rajasthan set a state-level record by adding 6.7 GW of combined solar and wind capacity in 2022.

In 2022, Türkiye's coal generation returned to its previous peak of 113.6 TWh, driven largely by imported coal, with Russia becoming the primary supplier and the import bill reaching a record $5.3 billion. While wind and solar combined for a 15.5% share of generation, solar deployment lags behind its potential and faces grid capacity barriers. Hydropower proved critical for energy security during a ten-day gas supply disruption from Iran in January 2022, demonstrating its flexibility as a complement to variable renewables.

Ember's analysis finds that the Whitehaven coal mine in Cumbria is likely to emit 15 times more methane over its lifetime than estimated by the developer, West Cumbria Mining Limited (WCML). The report argues that WCML understated methane content by using core samples instead of official National Atmospheric Emissions Inventory (NAEI) factors and overstated mitigation potential by claiming a 95% destruction rate, whereas the IEA suggests 69% is realistic for such mines. These discrepancies could lead to the mine producing 12 kilotonnes of methane in 2030, significantly impacting the UK's goals under the Global Methane Pledge.

The document critiques the findings of the Australian Senate Inquiry into the Safeguard Mechanism, noting that while the committee acknowledged the "massive climate harm" of coal mine methane, its final recommendations failed to provide a sufficient plan to tackle the issue. Ember proposes three specific improvements: implementing Level 5 Oil and Gas Methane Partnership 2.0 measurement standards, setting production-adjusted emissions intensity baselines (3 kg/tonne for coking coal and 1 kg/tonne for thermal coal), and limiting the use of offsets (ACCUs and SMCs) to prioritize onsite mitigation.

Ember's analysis suggests the Whitehaven coal mine in Cumbria will emit 15 times more methane over its lifetime than estimated by the developer, West Cumbria Mining Limited (WCML). The report argues that WCML underestimated methane risk by ignoring official UK emission factors and overstated the feasibility of its mitigation plans, which claim a 95% destruction rate compared to an IEA benchmark of 69% for coking coal mines. Consequently, the mine could substantially increase the UK's methane emissions from fossil fuel production by 2030, potentially jeopardising the UK's targets under the Global Methane Pledge.

The document analyzes the Australian government's proposed reforms to the safeguard mechanism and the subsequent Senate Committee inquiry. While the Committee acknowledged the "massive climate harm" of coal mine methane, Ember argues the final recommendations missed a key opportunity to mandate rigorous measurement, reporting, and verification (MRV) standards or a separate emissions intensity baseline for methane. The brief highlights that current reporting may underestimate methane emissions by 63% and warns that unlimited access to carbon offsets (ACCUs) weakens incentives for onsite mitigation. It recommends implementing Level 5 Oil and Gas Methane Partnership 2.0 standards and setting specific methane baselines for coking and thermal coal mines.

The report identifies two primary loopholes in the EU methane regulation: the weakening of venting thresholds for thermal coal and the delayed regulation of coking coal. These gaps are projected to result in an additional 2.2 million tonnes of methane emissions by 2050, failing the EU's 58% reduction goal. The analysis highlights that Poland is the primary source of EU coal mine methane (CMM), with seven high-methane thermal coal mines accounting for all of Poland's reported thermal hard coal emissions. Ember recommends tightening venting thresholds to 1 tonne methane/kilotonne of coal by 2030, prioritizing the retirement of high-methane mines, and implementing a 5 tonne threshold for coking coal to avoid 3 million tonnes of methane by 2050. Additionally, the report notes that Romania's abandoned mines represent a significant opportunity for methane capture, potentially generating 0.5 TWh of electricity.

The briefing argues that the EU is on course to reach a 45% renewable energy share by 2030, rendering the current 40% Fit-for-55 target outdated. This trajectory is driven by solar capacity growth, heat pump adoption, and electric vehicle expansion, which are all outpacing original policy forecasts.
