✈️ New legal opinion: airport capacity can be reduced on climate grounds under EU law 🌍 Our latest analysis challenges long-held assumptions about the EU Slot Regulation – and what it means for aviation and climate policy. 🧵 Thread 👇 #LawSky #ClimateSky

🚢 Last week’s decision at the @imohq.bsky.social was a huge setback for tackling shipping’s climate impact. What should have been a historic step toward net zero has instead been delayed. 🧵

🏭 As data centres boom, the US turns back to coal while the Global South leaps to solar. Read our Senior Director of Economics, @meadwaj.bsky.social, on this strange reversal in the global energy landscape – and why yesterday's "disadvantages" are becoming tomorrow's competitive edge. 👇 #GreenSky

🚢 New Arctic shipping route promises 50% cuts. But does it deliver? The Istanbul Bridge just completed the first China-Europe Arctic Express voyage in 21 days vs. usual 30-50. Yet, this route's climate benefits might be too good to be true. Read our Scientific Officer, James Kershaw's explanation👇

🚢 The next two weeks will shape international shipping's transition to net zero. Tomorrow the IMO gathers for MEPC/ES.2 to formally adopt the Net-Zero Framework – shipping's first global pollution fee. This will be followed by ISWG-GHG 20 next week. Here's what's at stake... 🧵 #ClimateSky

🚜 The agriculture & land use sectors account for up to 1/3 of global greenhouse gas emissions – so why are they lagging behind when it comes to global climate targets? Our latest blog explains why agribusinesses should get up to speed on climate action or face financial risks. ⤵️ bit.ly/46xATgB

🌾 The climate cost of agribusiness: why the sector faces growing legal risks. Agriculture is responsible for up to a third of global greenhouse gas emissions – yet policy action has been disappointingly slow. Now, climate litigation is stepping in to fill the gap. 🧵 1/4 #ClimateSky #LawSky
