by Mike Schuler (G Captain) Leading environmental organizations have submitted a joint proposal to the International Maritime Organization (IMO) calling for measures to prevent the shipping industry’s expansion into crop-based biofuels that could threaten climate goals, natural ecosystems, and food security.

Pacific Environment, Environmental Defense Fund, Clean Shipping Coalition, and the World Wildlife Fund are urging the IMO to incorporate strict safeguards against high Indirect Land Use Change (ILUC) biofuels in the upcoming technical working group meeting (ISWG-GHG-20) scheduled for October 20-24.

“Crop-based biofuels have been portrayed for decades as a ‘climate friendly’ solution for the transport sector but are tied to deforestation, food insecurity, and land and water grabbing,” the groups stated in their submission.

...

The organizations propose that the IMO should factor ILUC directly into lifecycle values, which would effectively exclude crop-based biofuels from ships. Alternative approaches include excluding or capping biofuels based on feedstock.

...

The submission encourages IMO Member States and international organizations to provide concrete proposals on incorporating quantitative metrics into a risk-based ILUC framework and establishing safeguards against high-ILUC risk feedstocks.

With palm oil plantations having grown 370% since 1990 and nearly half of that expansion occurring on high-carbon forests, the environmental groups emphasize that identifying and quantifying ILUC emissions is fundamental for recognizing the real impacts of these fuels. READ MORE

Excerpt from Pacific News Agency: IMO members are meeting next week (week of October 13, 2025) in London to vote on the adoption of the Net-Zero Framework.

Experts note that while biofuels can play a limited role in the transition, they are unlikely to meet the sector’s long-term needs. The aviation sector is already competing for the same feedstocks, creating a high risk that scarce resources will be diverted away from shipping.

Climate science underscores the urgency of focusing on scalable, long-run solutions. The latest assessments show global warming has already averaged 1.54°C above pre-industrial levels in 2024, with highly disruptive tipping points that are likely to be triggered between 1.5–2°C. “Investing in fuels that cannot scale wastes precious time we do not have,” Kautoke warns.

Instead, Pacific countries are pushing the IMO to design the Net-Zero Fund’s reward system to incentivise true zero-emission options – using mechanisms like auctions or contracts-for-difference to provide certainty for investors while ensuring accessibility for low-income countries.

“Member state priorities and preferences differ significantly when it comes to defining ZNZs. Our message is clear: the NZF needs to steer the environmental integrity of the long-term energy transition while ensuring food security. That means not rewarding the use of biofuels,” says Kautoke.

Excerpt from Biofuelwatch: Biofuelwatch, Forest Watch Indonesia and Global Forest Coalition are calling the International Maritime Organisation (IMO) to exclude harmful biofuels from compliance with the Net-Zero Framework. Last week, during the Extraordinary Session of the Marine Environment Protection Committee (MEPC ES.2) in London, countries decided to postpone the decision on the adoption of the Framework to 2026. But important discussions will continue on 20–24 October on key details on clean energy incentives in the Framework, and the organisations stress the importance of preventing biofuels from being included as a supposed “green” alternative to fossil fuels.

Decades of evidence show that indirect land use change (ILUC) emissions from crop-based biofuels – such as soy and oil palm – wipe out their claimed climate benefits, driving forest loss, food insecurity, and land and water grabbing as agriculture is displaced onto marginal or uncultivated land. Soy and oil palm-based biofuels can generate emissions even higher than fossil fuels.

“Biofuels are not a sustainable solution under any circumstances. In Latin America, the push for soy-based biofuels has accelerated deforestation and driven communities off their lands. If the IMO creates new demand for biofuels, it will unleash more emissions, more inequality, and more land grabbing” said Jana Uemura, Climate Campaigner at the Global Forest Coalition.

“Rejecting biofuels in the Net-Zero Framework means protecting the world’s remaining tropical forests – critical carbon sinks and biodiversity hotspots.” said Anggi Putra Prayoga, Forest Campaigner at Forest Watch Indonesia. “The climate crisis is already real. It is crucial to take a firm stance on adopting truly zero-emission energy sources, rather than biofuels that generate new emissions through deforestation.”

The example of Indonesia should be a warning to other countries. In Indonesia, the expansion of palm oil plantations for biofuel continues to drive deforestation – even within protected and conservation forests which are highly vulnerable to climate change. “The loss of forests not only worsens emissions but also endangers the lives and rights of Indigenous peoples who depend on forest resources,” added the Forest Campaigner.

To avoid these impacts, the IMO should make sure high-ILUC fuels are excluded in the Framework. Major national and industry frameworks, including the EU’s Maritime and Aviation policies, the UK SAF Mandate, and the International Civil Aviation Authority’s CORSIA scheme, already exclude or cap high-ILUC biofuels, or include ILUC emissions in the life cycle accounting. The IMO must not fall behind.

“We urge all IMO member governments to take a strong, united stance against the inclusion of biofuels in the Net-Zero Framework” said Pax Butchart, Biofuel Campaigner at Biofuelwatch, “the science is clear: crop-based and waste-derived biofuels cannot deliver real emissions reductions. Governments now have a historic opportunity to steer the shipping sector toward truly clean, zero-emission solutions that protect people and the planet.”

Equally, biofuels produced from waste and residues such as used cooking oil (UCO), have limited availability and scalability, and won’t be able to satisfy the demand of international shipping in the long run.

Recent research estimates that while used cooking oil (UCO) will be the cheapest pathway for compliance, its supply is highly constrained and largely already used in the transport sector. The global waste oil supply currently used for biofuels production could only meet about 5% of shipping’s energy demand, leaving the sector reliant on the next-cheapest compliance pathway, high-ILUC biofuels, with major sustainability risks. UCO and palm derivatives, such as palm oil mill effluent (POME) and palm fatty acid distillate (PFAD), have been associated with fraud, weak auditing and risk displacement from their current use, increasing the use of unsustainable palm oil elsewhere.

The IMO governments must now pursue truly sustainable alternatives, including improved energy efficiency, wind-assisted propulsion and reducing demand for maritime transport in international trade.

Background information

IMO governments decided to delay the adoption of the Net-Zero Framework by one year at the Extraordinary Session of the Marine Environment Committee (MEPC ES.2) meeting in London on 14–17 October. The negotiations on key technical details are set to continue until then, with a technical working group (ISWG-GHG-20) on implementation and design taking place on October 20–24.

Despite the delay in adoption of the Net-Zero Framework, the 2023 IMO GHG Strategy remains in place, setting net-zero targets for the IMO and international shipping by 2050. READ MORE

Excerpt from Supply Chain Brain: Wind-assisted propulsion is doubtless a crucial tool in cutting both emissions and general energy usage over long distances at sea. But to fully address the problem of shipping’s enormous carbon footprint, policy must go beyond techno-fixes to encompass the unspoken truth at the heart of this debate — that demand reduction is required to bring shipping in line with necessary decarbonization targets. There simply have to be fewer container ships, making fewer, shorter journeys, and carrying less freight. READ MORE
