Summer has brought record low R99 cash prices — and nearly 3.2mn bl of vessel-supplied renewable diesel — to key California distribution hubs, but those seeking to take long-term supply positions must grapple with changing incentive programs and yet unseen consequences for supply flows.
Looking ahead to the end of 2024, the future of RD supply is murky. Changing credit eligibility could discourage the volume of imports the west coast has grown accustomed to, domestic refining margins at the US Gulf coast have been indicated on the decline for much of the year, and a volatile underlying CARB diesel basis increases participants’ exposure to price risk.
Cash prices for R99 at the head of the pipeline (hop) in Los Angeles hit their lowest level in Argus series history on 6 August, when a downturn in the underlying CARB diesel basis pressured values to just $2.35/USG. The price slide, coupled with anecdotally unworkable spreads to local rack prices, weighed heavily on activity this summer, despite a steady stream of offshore shipments.
Deliveries via vessel to northern California in August were the second highest in Argus history at an estimated 741,000 bl — the latest in steady monthly increases since June — per data aggregated from bills of lading and global trade and analytics platform Kpler. Jones Act vessels from the US Gulf coast alone accounted for 448,000 bl, while shipments ex-Singapore constituted the remaining volume.
Southern California received an estimated 847,000 bl, almost evenly split between offshore suppliers and those at the US Gulf coast.
But the future of renewable diesel supply flows into California is mired with uncertainty surrounding incentives for both importers and domestic refiners. The BTC is set to expire with the 2024 calendar year, giving way to the IRA’s Clean Fuel Production Credit. The change would heavily favor US-based renewable diesel production and reduce awards for high-volume offshore imports to the US west coast, the latest pivot for an adolescent market that has struggled to achieve supply equilibrium.

Neste — the leading offshore supplier of US R99 — is also slated to undergo turnarounds at both its Rotterdam, Netherlands, and Singapore facilities this quarter, followed by a second short-term Singapore turnaround in the fourth quarter. But the import lineup so far does not reflect a disruption in deliveries to the US this quarter.
At home, refining margins at the US Gulf coast are indicated on the upswing after narrowing through early August.
Renewable diesel deliveries to the west coast by rail from other US regions reached a record-high of nearly 2mn bl in May, per data from the Energy Information Administration (EIA). Shipments by vessel are also trending higher, with an estimated 864,000 bl delivered to California in August — the highest since November.

Spot R99 markets in California were little tested at the end of August, although both the Los Angeles and San Francisco markets drew support from a controversial surprise proposal to limit California Low Carbon Fuel Standard credit generation for renewable diesel made from soybean or canola oils. The California Air Resources Board will also consider a one-time tightening of annual carbon reduction targets for gasoline and diesel by 9pc in 2025, compared with the usual 1.25pc annual reduction and a 5pc stepdown first proposed in December 2023, per a 12 August release.
But an unsteady economic landscape for domestic production remains a key decision-driver among US refiners.
Vertex Energy will begin reversing a renewable fuels hydrocracking unit back to conventional fuel feedstocks this quarter at its 88,000 b/d Mobile, Alabama, refinery. The company at the time cited headwinds in the renewable fuels market that it expects to persist through 2025.

Energy transition must 'reflect national circumstances'
Energy transition must 'reflect national circumstances'
Sao Paulo, 12 June (Argus) — The roadmap for the transition away from fossil fuels being drafted by the UN Cop 30 climate summit's presidency will "reflect diverse national circumstances", the Cop 30 presidency said on Friday during the Bonn climate talks. The roadmap — which was first proposed by Brazilian president Luiz Inacio Lula da Silva during Cop 30 , held in Brazil last November — will consider "different levels of socioeconomic development, energy access, fossil fuel dependency and capacity to transition", among other factors, the Cop 30 presidency said. The roadmap has so far received input from 115 countries and 247 non-state actors, the presidency said. The Cop 30 presidency has so far identified four main levers to accelerate the roadmap's implementation: Reforming the international financial architecture, which would include linking debt-relief mechanisms to the transition away from fossil fuels and increasing access to concessional finance and global carbon markets; Strengthening capacity-building, enabling technology sharing, in particular in transportation, supporting innovation in hard-to-abate sectors and increasing energy efficiency and electrification rates; Implementing regional and global cooperation mechanisms to reform international trade and legal framework for investments, and foster producer-consumer dialogue; Prioritizing the just transition, particularly for fossil fuel-dependent economies, by addressing competing development priorities, with information integrity and building trust across countries at different stages of development. During the meeting, a representative from the International Renewable Energy Agency agreed that electrification will be key to the global transition away from fossil fuels. The topic is set to take center stage during Cop 31, which will be held in Turkey in November, as that country has proposed a global goal for electricity to reach 35pc of global final energy consumption by 2035 as part of its action agenda. Some of the main barriers encountered so far for the transition away from fossil fuels are "structural imbalances in the global financial architecture, insufficient de-risking mechanisms and continued international finance flows towards fossil projects", the Cop 30 presidency added. The presidency has also found that the concentration of clean energy supply chains, the high-cost nature of nascent, hard-to-abate solutions, and limited technology sharing, as well as the absence of dedicated transition coordination mechanisms, also hinder the transition. Other factors such as insufficient political leadership, geopolitical uncertainty and armed conflicts — such as the Iran war — and outdated legal and trade frameworks are also hurdles for the transition. "The recent geopolitical crisis has shown very clearly how fossil fuels are linked to vulnerabilities, and we need to address this in the roadmap," Cop 30 president Andre Correa do Lago said. But the roadmap's implementation will be much easier than other climate negotiations, he added. "The great advantage of implementation is that we have much more freedom to implement than to negotiate," he said. "Negotiation requires consensus; implementation does not." The Cop 30 presidency expects to unveil the roadmap during Cop 31. It is also working on a roadmap to address deforestation, which it will also unveil at Cop 31.

Brazil waste oil mandate could raise biodiesel costs
Brazil waste oil mandate could raise biodiesel costs
Sao Paulo, 11 June (Argus) — The mandatory use of waste oils and fats (WOFs) in the production of biodiesel in Brazil is likely to raise product costs, considering the limited supply of these raw materials and competition from products with higher added value, such as sustainable aviation fuel (SAF) and hydrotreated vegetable oil (HVO). In May, Brazil's mines and energy ministry MME published a decree mandating the use of 1pc WOFs in the production of biodiesel, SAF and HVO starting 1 January 2028. Until then, the use of these raw materials is voluntary. Per the decree, the minimum percentage of WOFs will be reviewed every three years, based on factors such as the available quantity of the raw material, advances in traceability mechanisms, the expansion of collection infrastructure and increased pretreatment capacity. In Brazil, the market for used cooking oil (UCO) — one of the main types of WOFs — remains unregulated and lacks consolidated official data. Estimates of collection levels in the coming years vary widely, with projections ranging from 500,000 metric tonnes (t)/y to 2mn t/y, according to market participants. In 2025, biodiesel production used approximately 100,000t of UCO. When soybean oil prices are high, WOFs serve as an important alternative feedstock for biodiesel production, especially for non-vertically integrated plants. In 2025, for example, the average price of UCO fob Sao Paulo, with 3.5pc acidity was R5,438($1.051)/t. The price of soybean oil cif Sao Paulo stood at R5,808/t during the same period, according to Argus indicators. The mandatory use of WOFs may alter this trend, with increased demand from the biodiesel, SAF and HVO industries driving up the price of UCO and, consequently, the final product. The use of WOFs in biodiesel production is also expected to impact the glycerin market, which, because some countries accept only the byproduct derived from virgin vegetable oils, will need to diversify its consumer base. The Brazilian biofuels industry considers the deadline for the mandatory adoption of 1pc OGRs in biodiesel production to be insufficient, given the necessary adaptations required at plants that currently operate exclusively with virgin vegetable oils. A major biodiesel producer that acquired existing WOF plants in the Brazilian market told Argus that it has been involved for over three years in projects to adapt these industrial units. It considers it unfeasible for small-scale plants to complete all the required adjustments in just over a year and a half. The MME stated that the measure takes into account the sector's varying technological realities. The gradual implementation is specifically intended to allow for industrial adaptation and the expansion of processing capacity for these raw materials. Traceability initiatives Brazil's UCO market is maturing but, to date, lacks consolidated traceability projects. According to the MME, the period of voluntary use of WOFs was structured to allow for the sector's gradual adaptation, the development of collection and processing chains and the advancement of traceability mechanisms. In this context, Brazil's animal recycling association Abra is working to create a specific national classification of economic activities (CNAE) for UCO. The organization is also developing an app designed to record information on the collection and movement of the raw material, with the aim of reducing traceability gaps and increasing transparency throughout the production chain. Meanwhile, Brazil's state-controlled oil company Petrobras recently announced an investment of R23mn in initiatives for the collection of animal by-products intended for the production of biofuel. The funds will be directed toward projects by non-profit organizations to improve the logistics and infrastructure of collection points, including the provision of equipment for filtering and temporary storage of the product.

Global warming set to exceed 1.5°C by 2030: Scientists
Global warming set to exceed 1.5°C by 2030: Scientists
London, 11 June (Argus) — The rise in global temperature is projected to surpass 1.5°C above pre-industrial levels — the limit sought by the Paris climate agreement — "in about four years", an international team of more than 70 scientists said today. "Human-induced warming reached 1.37°C" in 2025, compared with the 1850-1900 average, the latest Indicators of Global Climate Change report found. The Paris agreement seeks to curb the global rise in temperature to "well below" 2°C above pre-industrial levels, and pursues a 1.5°C limit. "The rate at which heat is accumulating in the earth system suggests high levels of future warming", the report found. "The rate of human-induced warming remains at the all-time high of around 0.27°C per decade, driven primarily by record-high greenhouse gas levels." It estimated the remaining global carbon budget — the amount of CO2 that can still be emitted before the 1.5°C threshold is exceeded — is 130bn t/CO2, from the start of 2026. This estimate, which is a central one, "will be exhausted in around three years at current levels of CO2 emissions", the report found. Global greenhouse gas emissions reached a record high 56.8bn t/CO2 equivalent (CO2e) in 2024, according to the report, "mainly from the burning of fossil fuels." "Although we still have record high levels of emissions, the growth of those CO2 emissions is slowing," the EU Copernicus programme's strategic lead for climate Samantha Burgess said today. "That doesn't mean we're on track yet, but it does mean that policy, technology, and societal choices are starting to bend the curve." Burgess was speaking at climate talks underway in Bonn, Germany, hosted by UN climate body the UNFCCC. El Nino weather conditions have now developed in the tropical Pacific, the US National Oceanic and Atmospheric Administration (NOAA) confirmed today. The weather pattern, which is naturally-occurring, typically leads to higher global temperatures. Current forecasting suggest it is "likely to be a very strong event", the UK's Met Office said today. Some forecasts suggest "values that would be of record strength", the Met Office said. "It is also highly likely that the El Nino will cause a temporary spike in global annual temperature with the residual heat potentially making next year the hottest in the global series from 1850", Met Office head of long-range forecasting Adam Scaife said. The hottest year on record to date is 2024. The past three years, 2023-25, are the hottest three years recorded. The average temperature across 2023-25 was 1.48°C above pre-industrial levels — with a margin of uncertainty of 0.13°C — data consolidated by the World Meteorological Organisation show.

Bunker lead times grow since US–Iran war began
Bunker lead times grow since US–Iran war began
Sao Paulo, 10 June (Argus) — Shipowners and traders have been booking spot bunker fuel supplies further in advance since the start of the Iran–US conflict, according to data collected by Argus . The longer lead times, between the placing of a bunker fuel order and the fuel being supplied, reflect concerns about potential supply disruptions and strategies to deal with price volatility. Disruption to shipping through and around the strait of Hormuz has encouraged buyers to secure fuel as far as four to six weeks ahead rather than risk encountering shortages, market participants said. Argus ' bunker assessments are typically for deliveries with a maximum of 9-12 days and up to 14 days for certain African ports. The shift reflects concerns about reduced availability, with around 20pc of global crude having previously transited the strait now missing and therefore restricting supply of bunker grades. Higher freight costs have also reduced the economic incentive for suppliers to import fuel, which further reduced availability. Very-low-sulphur fuel oil (VLSFO) prices have strengthened sharply across major bunkering hubs since the start of the US-Iran war, reflecting tightening feedstock availability and growing supply concerns. Delivered VLSFO indications in Rotterdam have rose by around 45pc from 28 February to 31 May, prices in Panama increased by 49pc and in Singapore by 47pc. The tightening market has been particularly evident in Fujairah, the world's fourth-largest bunkering hub, where an acute supply shortage has left most suppliers without prompt VLSFO availability until mid-June. Market participants said disruptions to regional feedstock flows and the loss of supply from Kuwait's al-Zour refinery sharply reduced local blending activity, pushing Fujairah VLSFO premiums to record highs of $500-700/t against front-month Singapore cargo values in early June. The change in buying patterns has been happening worldwide. Delivery times for VLSFO in Singapore have extended to about 10-15 days forward in some cases, depending on supplies given tight blendstock availability, traders said this week. Typical delivery periods of about 7-10 days forward remain possible. Singapore loadings for low-sulphur marine gasoil (LSMGO) have also slowed, with market participants expecting this to ease only in the second half of June. LSMGO supplies are tight because of delays in cargo arrivals from South Korea, and most current availability will go towards previously booked orders. The lead time for high-sulphur fuel oil (HSFO) has been steady at around 4-5 days, as supplies are ample in Singapore. In Gibraltar, the average lead time in the three months before the war started was around five days. This is now 10 days. In Rotterdam the average booking period is up to 10 days from seven. In South America, rising vessel traffic through the Panama Canal has increased congestion and lengthened waiting times. The tighter transit window has pushed bunker buyers in Balboa and Cristobal to secure fuel further in advance, with market participants reporting a shift away from prompt procurement toward longer lead-time bookings to ensure product availability and align deliveries with delayed canal crossings. The average bunker fuel lead time in the Panama Canal increased to 14 days in March-May, from 10 days in the three months ending 28 February. In Brazilian ports, longer lead times have also been driven by rising fuel oil export flows to Singapore, where demand for Brazilian supply has increased because of the disruption linked to the strait of Hormuz. The additional export pull has reduced feedstock availability for VLSFO blending in Brazil, tightening prompt supply at key ports like Santos and Paranagua. Santos' average bunker fuel lead times increased to 10 days in March-May, from eight days in the three months to 28 February. In Paranagua, average lead times rose to 13 days from 10 days over the same period.
