Factsheet: the IMO Net-Zero Framework: what is it and how does it work? — Opportunity Green A factsheet to understand what has been agreed at the International Maritime Organization (IMO) MEPC 83 in April 2025 to cut international shipping emissions.

Last month at @imohq.bsky.social’s #MEPC83, states approved a draft Net-Zero Framework for shipping.

✅ A win for multilateralism
❌ But not enough for the climate

🤔 What actually got agreed?

We created a factsheet to help you understand the deal👇

A significant event for shipping! The momentous and action-packed #MEPC83 approved @imohq.bsky.social's Net-Zero Framework, which is the first ever fee-based #GHG emissions reduction measure based on 2-Tier GHG Fuel Intensity thresholds, on Well-to-Wake basis, for all vessels over 5000 GT. 1/2

Although the ambition of the agreed measures has fallen short of expectations, OceanCare welcomes the outcome at #MEPC83, where the International Maritime Organisation's (IMO) approved on a series of measures to reduce shipping emissions. 🚢 #ClimateAction #MartimeSector 1/3

#MEPC83 was a missed opportunity, but the baton now passes to national and regional authorities to raise their ambition and double down on efforts to decarbonise shipping and regulate to fill in the gaps the IMO agreement has left. 🌍🚢

🌎🚢 IMO negotiations ended in disappointment on Friday. What actually happened at #MEPC83 and why does it matter for shipping, climate and climate vulnerable nations?

Here’s a quick thread to get you up to speed, and read our PR on the IMO negotiations' conclusion. 👇

Shipping nations agree on historic greenhouse gas tax – DW – 04/11/2025 From 2027, all ships are required to use less CO2 emitting fuels, or face penalties. It is aimed at forcing the industry to lower its carbon footprint and not everyone is happy with the deal.

Last week countries agreed a historic shipping decarbonisation plan 🚢🌡️

"This should signal a turning of the tide on greenhouse gases from global shipping. However, key aspects of this agreement fall short of what is needed" says WWF's @marklutes.bsky.social #IMO #MEPC83 #ClimateAction

🚢The IMO laid a foundation — but not enough. The energy transition is happening. Industry must lead:

✅ Invest in wind & clean fuels
✅ Avoid short-term LNG traps
✅ Push equity in the transition

A groundbreaking global deal just landed to cut emissions from shipping

This makes shipping the first global sector with a regulated pathway to net zero, but key aspects of the agreement fall short of what is needed to drive rapid action in the near term #IMO #MEPC83 #ClimateAction

🚨 🚢 | BREAKING: A groundbreaking shipping deal just landed putting the sector on a path to net zero by 2050 - but weak measures risk blowing progress off course

It’s a big step, but our experts warn it’s not moving fast enough to tackle the climate crisis #IMO #MEPC83

This week, our Director of Skills and Education, Tim Slingsby, attended the IMO #MEPC83, speaking alongside Costas Triantafillou, Head of Strategy and Development at HELMEPA, and a panel of global maritime industry experts.

World's first-ever global emissions tax is on the table at crunch shipping talks Although far from a foregone conclusion, a robust pricing mechanism in the shipping sector would be considered one of the climate deals of the decade.

"It’s not really a question of whether they get agreement, it’s just how ambitious it is, how effective it is and how many unhappy people there are. " - John Maggs cnbc.com/2025/04/09/c...

⚓️The International Maritime Organization is meeting in London at #MEPC83 to discuss decarbonization. The future of shipping and energy transition CANNOT rely on biofuels! Biofuels drive deforestation and harm human rights. Shipping shouldn't fuel another environmental disaster!

Malgré un soutien grandissant, de lourds dissensus persistent entre les États, et une nouvelle mouture de cette taxe vient d'être mise sur la table avec des niveaux de taxations différents selon le niveau d'émissions des navires. #MEPC83

Transport maritime : la taxe carbone en ballotage 176 pays se réunissent cette semaine pour cinq jours pour décider des modalités d’une possible taxe carbone internationale sur les plus gros navires marchands. Face aux importants dissensus, une propo...

Mettre en place une taxe carbone internationale sur le transport maritime est un levier qui semble incontournable pour décarboner le secteur, et pourrait être décidé cette semaine, à Londres lors d'une réunion de l'IMO International Maritime Organization www.rsedatanews.net/article/arti... #MEPC83

Important international talks are underway this week focussed on cutting shipping emissions and protecting the marine environment

WWF's Melanie Lancaster spoke on the first day about the need to reduce underwater noise

Tomorrow, our Director of Skills and Education, Tim Slingsby, will attend the IMO's #MEPC83 - discussing the Foundation-funded and HELMEPA-led #METAVASEA programme, which is advancing a people-centred transition for maritime decarbonisation. Learn more about the programme: youtu.be/11Qg5mUTlrM

This week will define the future of #shipping and it is a key moment for #climate action and #multilateralism! #IMO #MEPC83

@dcuclimate.bsky.social

"During #MEPC83, IMO member states must knuckle down and approve an ambitious fuel standard and a high levy on all GHG emissions from ships - or risk missing the IMO’s goals for emission reduction and clean energy uptake, with the threat of increasing inequity.”

“During #MEPC83, govs must adopt a proposal calling for a resolution urging member states and ship operators to avoid using scrubbers in IMO-designated particularly sensitive sea areas (PSSAs)..." eelcoleemans.bsky.social cleanarctic.org/2024/02/14/i...

Landmark deal to put shipping on course for net-zero is in sight Governments will try to agree on how to get the shipping industry to meet its net-zero goal. The discussion includes a levy and green fuel.

A net zero shipping deal is in sight! 🚢

Next week, countries have the opportunity to secure a landmark agreement that would see the sector rapidly cut emissions and environmental harms

2025 will be crucial for #shipping decarbonization with key decisions expected at #MEPC83

@dublincityuni.bsky.social is proud to support negotiations by training members of #IMO delegations. Yesterday, we welcomed 70 delegates from over 30 governments.

Many thanks to all who made this possible!
