🎉 This week we’re welcoming two new Legal Officers to our team – Lucía Saborío Pérez & Laurent Sammouri! Lucía’s work will be focussed on building legal strategies in the shipping sector, and Laurent's role will cut across a range of legal approaches and industries. A huge OG welcome to you both!

✈️ Every transport sector pays for its pollution. Except one. Cars. Trains. Trucks. All are subject to fuel taxes, VAT and carbon pricing. Aviation? Still mostly exempt. 📲 Share this post if you think aviation should pay its fair share.

🚼 Two weeks’ paternity leave is still the UK norm – that’s a problem. At Opportunity Green, all parents get 6 months’ full pay + up to 12 months’ leave with pension contributions throughout. Equal leave doesn’t just support families, it helps close the gender gap. Read more👇

✈️ Aviation’s climate impact goes beyond CO₂ – and it’s time to fix it. Flights departing Europe emitted 140 million tonnes of CO2 in 2023 – roughly equivalent to the entire annual emissions of the Netherlands. But CO2 is only one part of the story. 🧵👇 #ClimateSky #GreenSky

✈️€26 billion. That’s what the EU has lost because international flights aren't charged for their pollution. Now the EU must decide whether to close that gap. We break down what the ETS is, why international aviation has been left out and what's at stake. Watch our ETS 101 video below👇 #ClimateSky

🚢 Mega profits, micro taxes: is global shipping paying its fair share?  From 2019–2023, the world’s largest shipping companies made $300bn in profits. Our latest update shows that in 2024 alone, they made $42.9bn – nearly double the previous year. So where did all that money go? 🤔🧵 #ClimateSky

✈️ A short flight in Europe? You pay for the emissions. A long-haul flight to New York or Dubai? You don’t. That’s the gap left by the EU’s Emissions Trading System (ETS). 1.1bn tonnes of CO₂ unpriced. €26bn missed. The EU is now deciding whether to fix it. Our FAQ explains what's at stake👇

✈️ Can airlines be competitive and meet climate goals? YES. By extending the EU ETS to international flights – a polluter pays approach that funds climate action. Since 2012, it could have raised €26 bn. With the ETS under revision this year, there’s a real opportunity. Read more 👇 #ClimateSky
