Why Europe’s data-center label may not reveal the sector’s true footprint

The complaint from Lighthouse Reports argues that EU confidentiality rules breach access-to-information rights under the Aarhus Convention by preventing disclosure of facility-level energy and water data.[1] Commission figures show European data centers consumed 20.7 terawatt-hours of electricity and more than 8 million cubic meters of water in 2025, although incomplete reporting means those totals do not capture the sector’s full use.[1] Carbon-pricing systems now cover roughly 30% of global emissions, twice their 2020 reach, as countries including India and Vietnam begin applying limits to heavy-emitting sectors such as steel and cement.[2] Separately, a coalition co-chaired by China, Brazil and the European Union approved a work plan through 2030 aimed at making national carbon markets work with one another.[3] El Niño conditions appeared in the central and eastern equatorial Pacific in May, after which sea-surface temperature indices rose rapidly, according to China’s National Climate Centre.[4] Officials project the index will peak around November at 3.2°C to 3.5°C, which would make the event the strongest since instrumental measurements began.[4]

How emerging economies are redrawing the map of carbon pricing

Carbon-pricing systems now cover roughly 30% of global emissions, twice their 2020 reach, as countries including India and Vietnam begin applying limits to heavy-emitting sectors such as steel and cement.[2] Separately, a coalition co-chaired by China, Brazil and the European Union approved a work plan through 2030 aimed at making national carbon markets work with one another.[3]

Why it matters

Broader coverage puts more industrial emissions under an explicit cost or cap, while cooperation between markets could determine whether national systems can interact rather than remain isolated.[2][3]

Key insights

  • The global emissions share covered by carbon-pricing measures has doubled from about 15% in 2020 to roughly 30%.[2]
  • The emerging-market expansion reaches difficult-to-decarbonize industries, including steel and cement.[2]
  • The coalition approved its 2030 work plan at its second meeting in Wuhan, and Brasília is negotiating a carbon-market agreement with Beijing.[3]

How a record-strength El Niño could amplify climate disruption

El Niño conditions appeared in the central and eastern equatorial Pacific in May, after which sea-surface temperature indices rose rapidly, according to China’s National Climate Centre.[4] Officials project the index will peak around November at 3.2°C to 3.5°C, which would make the event the strongest since instrumental measurements began.[4]

Why it matters

The projected peak provides a measurable near-term indicator of an extreme Pacific warming event that can compound heat in an already warming climate system.[4][5]

Key insights

  • The event’s development is being tracked through sea-surface temperature indices in the central and eastern equatorial Pacific.[4]
  • China’s projected November peak is between 3.2°C and 3.5°C.[4]
  • The 2026 UN Climate Summit emphasized adaptation, resilience monitoring and renewable-energy deployment as key responses to intensifying climate impacts.[5]
