“Investors need to recognise the potential financial and reputational liabilities – even before regulatory breaches occur – and take action as recommended in this briefing.”

“The litigation risk posed to big polluters is significant and foreseeable. Companies could face claims for personal injury, private nuisance, negligence and human rights-based challenges,” says our Legal Manager, Matilda Graham.

Together with @foxglovelegal.bsky.social and @globalactionplan.bsky.social, OG has submitted evidence to the Environmental Audit Committee calling for data centre energy demand to be properly accounted for within the UK’s decarbonisation plans, alongside other recommendations.

🧵5/5

Despite this, the UK government is actively encouraging data centre expansion and is not yet accounting for their energy use or emissions in the last carbon budget set by the Committee on Climate Change.

3️⃣ Because data centres (particularly those supporting AI) require high, continuous power and are expanding at speed, this rapidly growing demand is mainly being met by fossil fuels.



🧵3/5

1️⃣ The UK already has the third highest number of data centres in the world, behind only the US and Germany – with around 100 more currently in planning.


2️⃣ If built and operated, proposed developments could add electricity demand equivalent to almost the entire country of Denmark.

⛽ The SASHA Coalition grew to 18 members, accelerating green hydrogen in shipping and aviation, with strategic expansion in Brussels and Dublin.

📚 Expanded our work across shipping, aviation, steel, agriculture, finance, trucks and data centres.

🇪🇺 Continued our EU Taxonomy legal challenge, with a court date set for early next year, contesting flawed sustainable finance rules that label polluting planes and ships as “green”.

🇺🇳 Alongside @maketheshift.bsky.social, we contributed to the UN Committee on Economic, Social and Cultural Rights recognising for the first time in its UK review that states must decarbonise housing to comply with international human rights law.

Some of our key impacts in 2025:

⚖️ Won a landmark ruling against MSC Cruises, with the UK Advertising Standards Authority confirming LNG is not green.

⚖️ Filed Europe’s first climate-related OECD complaint in the steel sector against ArcelorMittal.

📌 Why this matters now

The 2026 EU ETS revision is a crucial chance to align aviation policy with climate science and regulate aviation’s full climate footprint.

📄 Our new factsheet explains how EU policy measures against the science of aviation’s non-CO₂ impacts and what needs to change 👇

🧵 4/4

In 2023, flights departing Europe emitted 140m tonnes of CO₂ – about the same as the Netherlands’ total emissions.

Yet, the EU ETS:
- Only prices flights within Europe.
- As a result, over 1bn tonnes of CO₂ went unpriced between 2012-2023.
- Does not price non-CO₂ impacts.

🧵 3/4

Flying doesn’t just warm the planet through CO₂.

Non-CO₂ effects – especially contrails and nitrogen oxides (NOx) – can add up to roughly twice the climate impact of CO₂ on short timescales.

The problem? EU policy barely addresses this.
