⛽ 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.

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 👇

How EU policy measures against the science of aviation non-CO2 impacts — Opportunity Green
This factsheet reveals the huge impact of non-CO₂ effects like contrails – and why the 2026 EU ETS revision is a vital chance for the EU to finally tackle aviation’s full climate footprint.

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.

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.

“By taking this legal action, we hope to engage with ArcelorMittal on the actions it must take to address its climate impacts in line with the OECD Guidelines,” says our Legal Manager, Kirsty Mitchell.

OECD complaint filed against steel major ArcelorMittal over climate inaction — Opportunity Green
Opportunity Green has filed an unprecedented complaint under the OECD Guidelines, arguing that Europe’s largest steel producer, ArcelorMittal, is failing to address its climate impact.

This is not only unacceptable given the urgency of the climate crisis, it is also inconsistent with the OECD Guidelines. These expect multinational enterprises to operate responsibly – including by adopting and implementing science-based climate strategies aligned with the 1.5ºC limit.

The problem: Despite promising a revised climate strategy by 2024, ArcelorMittal hasn't published one since July 2021.

Their excuse? "Policy uncertainty."

The steel sector is responsible for ~8% of global emissions.

ArcelorMittal is Europe's largest steelmaker, yet 75% of its steel is still coal-based, emitting over 100m tonnes of CO2e annually.

Aoife also called on the EU to include international flights in the ETS in 2026.

“Aviation has enjoyed free passes on climate for far too long and next year the EU has the chance to put that right by including emissions from international flights in the ETS."

More countries are backing fair levies on premium flights to fund climate action, even as ICAO tries to limit such efforts. 👏

These solidarity surcharges can generate meaningful finance for countries most impacted by aviation’s emissions.
