Dec 1 – Early December: Calls for policy shifts and investor optimism

Germany urged to prioritize consumers in grid expansion

E.ON’s CEO asked Germany to give priority to households and job‑creating businesses when connecting new projects to the electricity grid. Renewable sources already supply more than 60 % of Germany’s power, but he said adding wind farms with high integration costs delivers little benefit. He also proposed ending long‑term solar subsidies, which he said impose billion‑euro burdens on ratepayers.

Investors maintain climate focus despite political headwinds

At the Reuters Next conference, leaders from Temasek and Builders Vision said long‑term investors remain focused on energy security and climate opportunities. Clean‑energy stocks have outperformed the broader S&P 500, rising about 48 % so far in 2025 versus 16.5 % for the benchmark index. The panel noted that climate and energy themes will shape portfolios regardless of U.S. policy roll‑backs.

Dec 9 – Dec 12: Warming milestones and regulation rollbacks

2025 set to be among the hottest years on record

Europe’s Copernicus Climate Change Service projected that 2025 will likely be the second‑ or third‑warmest year ever recorded. The average global temperature for 2023‑2025 is expected to exceed the 1.5 °C threshold relative to the 1850–1900 baseline, marking the first three‑year period above this level. Scientists warned that Typhoon Kalmaegi and Spain’s deadly wildfires were examples of extreme events made more intense by climate change.

EU waters down corporate sustainability rules

EU lawmakers narrowed the scope of the Corporate Sustainability Reporting Directive and the due‑diligence law. Only companies with more than 1 000 employees and €450 million turnover must report environmental and human‑rights risks under the CSRD, while the due‑diligence directive will apply only to firms with over 5 000 staff and €1.5 billion in revenue. Requirements for climate transition plans were dropped, raising concerns that the EU is retreating on transparency and accountability.

La Niña expected to end early 2026

The U.S. Climate Prediction Center forecast that the current La Niña will fade by January–March 2026. Neutral conditions are expected with a 68 % probability, which could improve crop yields but may also bring wetter weather to southern Brazil and Argentina. La Niña’s cooler Pacific waters have increased flood and drought risk in some regions.

Dec 13 – Dec 16: Extreme weather and clean‑energy expansion

Researchers link Southeast Asian storms to warming and deforestation

The Sustainable Switch newsletter reported that deadly storms in Sri Lanka, Indonesia, Malaysia and Thailand were supercharged by sea temperatures 0.2 °C above the 1991‑2020 average. Cyclone Ditwah alone killed over 600 people and caused US$7 billion in damage. Scientists said global warming and mangrove destruction made the storms far more intense; without warming the ocean would have been about 1 °C cooler.

ReNew partners with Google on 150 MW solar project

Indian renewables firm ReNew signed a deal with Google to build a 150 MW solar plant in Rajasthan. The project will supply about 425 000 MWh of clean electricity per year – enough to power more than 360 000 households – and aligns with India’s goal to double non‑fossil capacity to 500 GW by 2030. Google aims for carbon‑free energy 24/7 in Asia by 2030.

EU Parliament approves diluted sustainability law

The European Parliament passed a compromised version of the sustainability due‑diligence law. The vote clears the final hurdle for legislation that dramatically reduces the number of companies required to assess environmental impacts.

Dec 17 – Dec 19: Carbon politics and energy funding

U.S. moves to dismantle climate research centre

The Trump administration announced plans to dissolve the National Center for Atmospheric Research and transfer its activities. Officials derided NCAR as a source of “climate alarmism” and proposed deep budget cuts to NOAA’s climate research division. Colorado’s governor warned that weakening NCAR would jeopardise vital weather forecasting and America’s competitive edge.

EU expands and tightens its carbon border levy

The European Commission proposed broadening the Carbon Border Adjustment Mechanism to cover more downstream products such as car parts and washing machines. It also sought to close loopholes by including scrap metals and introducing default emissions values for importers who under‑report. A quarter of revenue would be returned to industries investing in low‑carbon production. European steel and aluminum producers welcomed the step but urged the EU to include post‑consumer scrap to prevent carbon leakage. Brussels reiterated that Britain would not receive an exemption from the levy unless the UK links its carbon market with the EU’s.

Germany launches a €30 billion public‑investment fund

Berlin unveiled the Deutschlandfonds, which aims to mobilise €130 billion of private capital for industrial decarbonisation, renewable infrastructure and deep‑tech startups. The state will provide €30 billion in guarantees and equity stakes, including €8 billion to support heavy industry and a €600 million guarantee to encourage geothermal drilling. Officials said the fund would help Germany maintain competitiveness while cutting emissions.

Global coal demand peaks amid energy transition

The International Energy Agency’s Coal 2025 report said coal use reached a record 8.85 billion tonnes in 2025 but is likely to plateau and decline by the end of the decade as renewables, nuclear and gas expand. India’s coal consumption fell due to increased hydropower and lower demand, while U.S. coal use edged up because of high gas prices and policy support.

Jostling over EU climate policy

Germany’s economic minister defended a scaled‑back plan to build only 10 GW of new gas‑fired power plants – down from 20 GW – after pro‑industry voices feared reliability risks. The plants must be hydrogen‑ready and carbon‑neutral by 2045. In neighbouring Czechia, the industry minister argued that the EU must rethink its climate aims or risk losing competitiveness, urging Brussels to scrap its planned carbon market for buildings and road transport.

Further energy and investment moves

The EU rejected a UK request for an exemption from its carbon border levy, meaning British steel and cement producers will face import charges unless the UK aligns its carbon market. Meanwhile, the UAE’s ADNOC raised $11 billion through a pre‑export financing deal to monetize future gas production from its Hail and Ghasha projects, with heavy participation from Chinese banks.

Private investment and green hydrogen projects

A Just Energy Transition Partnership study estimated Indonesia needs $31 billion of investment by 2030 and $92 billion by 2050 to decarbonize its coal‑heavy captive power sector. Renewable power’s share in captive generation could rise from 9 % in 2024 to over 80 % by 2050. Separately, the International Renewable Energy Agency’s head predicted that sustainable biofuels will be a central focus at COP 30 and called for a pledge to quadruple production by 2035.

Carbon capture deal signals growing investor interest

Italian energy firm Eni sold 49.99 % of its carbon‑capture unit to BlackRock’s Global Infrastructure Partners. The joint venture will develop carbon‑storage projects in the UK’s Liverpool Bay and Bacton gas fields and the Netherlands’ L10‑CCS site. Eni said the partnership boosts its industrial potential; critics note that carbon capture remains expensive and unproven at scale.
