Pennsylvania high court maintains RGGI stay

Market: Emissions
01/09/22

The Pennsylvania Supreme Court yesterday opted against overruling a lower court's decision to temporarily block the state from participating in the Regional Greenhouse Gas Initiative (RGGI).

The Supreme Court's decision means that a lower court's preliminary injunction, which halted enforcement of a regulation that cleared the state to join RGGI, will remain in place for at least the near future.

The state's efforts to participate in the eastern US power plant cap-and-trade program have been mired in legal challenges for months.

The Commonwealth Court first handed down the injunction in July, finding that Republican lawmakers and a coalition of coal-related groups had raised "substantial" questions about the RGGI rule's legality. Although Pennsylvania regulators' subsequent appeal functioned as an automatic "supersedeas" under state law, temporarily staying that injunction, the Commonwealth Court issued another order to again block the rule's enforcement.

The Department of Environmental Protection (DEP) had asked the Supreme Court to reinstate that stay of the injunction while legal proceedings play out, with the state poised to lose out on hundreds of millions of dollars in potential auction revenues. And in a filing last week, DEP asked the Supreme Court to expedite its review of RGGI-related cases and to promptly schedule an argument session on the injunction's legality.

The court's order yesterday rejects DEP's request to stay the injunction though it does not weigh in definitively on DEP's claims that the injunction was wrongly decided.

Pennsylvania, which will miss next week's auction because of these legal challenges, will also miss the 7 December auction unless the injunction is lifted by 23 October, DEP says.

Unless the Supreme Court gets more involved in the cases, the Commonwealth Court has scheduled its own argument sessions for this autumn. A September session will explore Republicans' claims that the state sought to publish the RGGI rule prematurely, while the more important November session will consider RGGI opponents' broader claims that the rule is unlawful.

The court has also expressed interest in an argument session next February to review claims raised by a group of owners of natural gas-fired power plants in a related case about the RGGI rule's legality.

EU publishes CO2 car standard tweak proposal

Brussels, 1 April (Argus) — The European Commission has published the long-awaited proposal to give automobile manufacturers more flexibility in complying with the bloc's CO2 reduction targets for cars and passenger vehicles in 2025, 2026 and 2027. Those three years would be assessed jointly, rather than annually, averaging out fleet emission performance. EU climate commissioner Wopke Hoekstra said the additional compliance flexibility shows that the commission has "listened" but the EU is still maintaining its zero-emission targets [for new vehicles from 2035]. "Predictability in the sector is crucial for long-term investments," said Hoekstra. The commission urged the European Parliament and EU member states to reach agreement on the targeted amendment "without delay". German centre-right member Jens Gieseke said there is a "broad majority" in parliament to fast-track approval for May. He noted that the car industry faces over €15bn ($16bn) in penalties for non-compliance with the CO2 standards. A member of parliament's largest EPP group, Gieseke also called for the commission to go further towards technological neutrality. "We need different kinds of fuels, e-fuels, biofuels, every fuel which could help to reduce CO2 should be recognized," he added. This second step, withdrawing the phase-out of internal combustion engines (ICE) from 2035 onwards, Gieseke noted, should come in the last quarter of 2025. German Green MEP Michael Bloss disputed the figure of €15bn in potential fines put forward by automotive industry association ACEA. "Even in the worst-case scenario, the total fines for all car manufacturers would not exceed €1bn," said Bloss. "Car manufacturers have had enough time to adjust their production planning. Many have done so," Bloss said, pointing to Automaker Volvo. Under the current 2019 regulation, fines should be imposed on manufacturers for each year in 2025–2029 when they do not reach their specific fleet-wide target CO2 reductions, compared to 2021 values. But manufacturers have the option to form compliance pools with other firms. "European car manufacturers are already talking to Tesla or Chinese manufacturers about so-called pooling, which must be stopped quickly," said EPP climate and environment spokesman Peter Liese. "We want to maintain climate targets, but not make Elon Musk richer through European legislation," said Liese.

EU commission's CO2 tweak for cars imminent: Update

Updates with likely date for approval Brussels, 31 March (Argus) — The European commission could approve a legal proposal for a limited revision of the bloc's 2019 regulation setting CO2 emission performance standards for new passenger cars and light commercial vehicles (LCVs) on 1 April, an official said. A draft proposal circulating does not change the substance of the 2019 rules but specifies a three-year compliance period (2025-2027) used to calculate potential excess emissions premiums. And the 29-page legal proposal does not alter the bloc's 2030 emissions reduction target to reduce economy-wide CO2 emissions by 55pc, compared to 1990. Nor does it lower the overall CO2 emission standards, the commission said. If agreed by the European Parliament and EU member states, the "one-off" three-year compliance period over 2025-2027, instead of an annual assessment, would provide additional flexibility for vehicles manufacturers, while maintaining investor certainty and predictability, the commission added. The 2019 regulation requires annual EU fleet-wide average CO2 emissions from new cars and new vans to be reduced in five-year intervals. For each year in 2025–2029, a target reduction of 15pc, compared with 2021 values, would normally be applied. Without any legal change approved by parliament and EU states, manufacturers exceeding their specific emissions targets, would have to pay excess emission premiums of €95 per g/km for each new vehicle registered. The commission is also "accelerating" work on a review that will commence "in good time this year", said the commission's energy and climate spokesperson Anna-Kaisa Itkonen. But she had "nothing new" on whether compliant fuels could be expanded beyond e-fuels to include other low-carbon and zero-carbon, such as biofuels.

World Bank loans Peru $500mn for climate adaptation

Lima, 31 March (Argus) — The World Bank loaned Peru $500mn to fund public climate adaptation programs, including investments for developing its burgeoning renewable energy sector, distributed generation and electric mobility. This new funding, requested by Peru's government and approved by the World Bank, aims to build on reforms to strengthen Peru's climate resilience and adaptation. Peru is considered among the countries most vulnerable to disasters driven by climate change, including earthquakes, flash floods, landslides and glacier melting. The loan will go toward funding energy transitions in key sectors like electricity and transportation, as well as developing sustainable cities and clean technologies, the World Bank said. It is also expected to strengthen disaster risk management through a national coalition of government agencies tasked with prevention and mitigation of disasters, including climate-related ones. These initiatives could include implementing a geo-referenced information system that helps in early mitigation and decision-making. Peru has had a sluggish transition in its renewables sector, but last year wind power production grew by 66pc and solar by 32pc over the year prior. In January, overall renewable power production grew by 16pc over the same month last year, with hydroelectricity leading most of that growth. Peru's electricity grid is mostly powered by natural gas — about 51pc thermoelectricity, 38pc hydropower, 7pc wind and 3pc solar electricity. Peru's congress passed a new electricity law in January, easing the path for renewable energy companies to compete for public electricity contracts and potentially reduce costs. Though the law has not yet been implemented, it faced stiff opposition from Peru's oil and gas industry which argued it gave unfair favoritism to renewable companies.

Global energy mix evolves as electricity demand surges

Climate change is becoming a bigger factor behind electrification, but cleaner energy use is slowing the growth in global emissions, writes Georgia Gratton London, 28 March (Argus) — A substantial increase in electricity demand — boosted by extreme weather — drove an overall rise in global energy demand in 2024, lifting it well above the average pace of increase in recent years, OECD energy watchdog the IEA announced this week. This led to a rise in natural gas consumption, although renewables and nuclear shouldered the majority of the increase in demand, leaving oil's share of total energy demand below 30pc for the first time. Global energy demand rose by 2.2pc in 2024 compared with 2023 — higher than the average demand increase of 1.3pc/yr between 2013 and 2023 — according to the Paris-based agency's Global Energy Review . Global electricity consumption increased faster, by 4.3pc, driven by record-high temperatures — that led to increased cooling needs — as well as growing industrial consumption, the electrification of transport and the rapid growth of power-hungry data centres needed to support the boom in artificial intelligence, the IEA says. Renewables and nuclear covered the majority of growth in electricity demand, at 80pc, while supply of gas-fired power generation "also increased steadily", the IEA says. New renewable power installations reached about 700GW in 2024 — a new high. Solar power led the pack, rising by about 550GW last year. The power generation and overall energy mix is changing, as economies shift towards electrification. The rate of increase in coal demand slowed to 1.1pc in 2024, around half the pace seen in 2023. Coal remained the single biggest source of power generation in 2024, at 35pc, but renewable power sources and nuclear together made up 41pc of total generation last year, IEA data show. Nuclear power use is expected to hit its highest ever this year, the agency says. And "growth in global oil demand slowed markedly in 2024", the IEA says, rising by 0.8pc compared with 1.9pc in 2023. A rise in electric vehicle (EV) purchases was a key contributor to the drop in oil demand for road transport, and this offset "a significant proportion" of the rise in oil consumption for aviation and petrochemicals, the IEA says. Blowing hot and coal Much of the growth in coal consumption last year was down to "intense heatwaves" — particularly in China and India, the IEA found. These "contributed more than 90pc of the total annual increase in coal consumption globally", for cooling needs. The IEA repeatedly noted the significant effect that extreme weather in 2024 had on energy systems and demand patterns. Last year was the hottest ever recorded, beating the previous record set in 2023, and for CO2 emissions, "weather effects" made up about half of the 2024 increase, the watchdog found. "Weather effects contributed about 15pc of the overall increase in global energy demand," according to the IEA. Global cooling degree days were 6pc higher on the year in 2024, and 20pc higher than the 2000-20 average. But the "continued rapid adoption of clean energy technologies" restricted the rise in energy-related CO2 emissions, which fell to 0.8pc in 2024 from 1.2pc in 2023, the IEA says. Energy-related CO2 emissions — including flaring — still hit a record high of 37.8bn t in 2024, but the rise in emissions was lower than global GDP growth. Key "clean energy technologies" — solar, wind and nuclear power, EVs and heat pumps — collectively now prevent about 2.6bn t/yr CO2 of emissions, the IEA says. But there remains an emissions divide between advanced and developing economies. "The majority of emissions growth in 2024 came from emerging and developing economies other than China," the agency says, while advanced economies such as the UK and EU cut emissions last year and continue to push ahead with decarbonisation.
