Japan’s Oil Giants Hit the Brakes on Decarbonization, Reinvest in Fossil Fuels

In a sharp reversal of recent energy trends, Japan’s top oil refiners are pulling back from ambitious decarbonization goals and instead doubling down on fossil fuels, citing soaring costs, policy uncertainty, and mounting energy security concerns. The move marks a significant recalibration for one of the world’s most energy-dependent nations—and signals a broader global hesitation around the pace and feasibility of the energy transition.

From Decarbonization Dreams to Energy Reality

For much of the past decade, Japan’s oil majors have made headlines with bold climate commitments. Hydrogen, ammonia, and synthetic fuels were touted as future cornerstones of a cleaner national energy portfolio. But in recent months, that vision has dimmed.

Eneos Holdings, Japan’s largest oil refiner, has officially scrapped its previous goal of supplying up to 4 million metric tons of hydrogen by 2040. In a statement this week, CEO Tomohide Miyata was blunt: "The trend toward a carbon-neutral society is slowing… we’re re-evaluating investment timing based on current global and domestic realities."

Instead of pursuing costly low-carbon initiatives with long ROI timelines, Eneos will boost investments in liquefied natural gas (LNG) and oil—resources that are already integrated into global supply chains, profitable, and viewed as more resilient amid inflation and supply chain pressures.

Miyata’s comments were echoed by Idemitsu Kosan, Japan’s second-largest refiner, which announced it was cutting its decarbonization investment budget by roughly 20%, scaling it back from 1 trillion yen ($6.9 billion) to around 800 billion yen for the 2023–2030 window. President Noriaki Sakai stressed the need for a “flexible approach” to carbon neutrality, acknowledging that momentum for climate action is slowing—particularly amid ongoing global energy uncertainty.

Why This Matters: Energy Security Trumps Idealism

The shift from "transition" to "stability" in Japan’s energy planning isn’t occurring in a vacuum. After the 2011 Fukushima disaster, Japan’s reliance on fossil fuel imports skyrocketed, as much of its nuclear fleet was taken offline. Today, Japan imports over 90% of its energy, making it one of the most import-reliant economies in the OECD.

This dependency has made Japan acutely vulnerable to geopolitical shocks—from Russia’s invasion of Ukraine to instability in the Middle East. In this light, the pivot back to fossil fuels is not just economic; it’s strategic.

Hydrogen and ammonia, while promising in theory, require massive upfront capital, international partnerships, and long-term government incentives to scale—none of which are guaranteed in today’s inflationary and fragmented global environment.

A Global Reassessment Is Underway

Japan is not alone in its recalibration. In February, BP scaled back its emissions reduction targets and redirected more capital to oil and gas. Equinor, Norway’s state-backed energy company, abandoned its 2030 goal for renewable investments. And at this year’s CERAWeek energy conference in Houston, industry leaders across the fossil fuel and renewable divide shifted rhetoric from "energy transition" to "energy additions"—a recognition that fossil fuels will remain foundational for decades to come.

For Japan, this new realism is backed by data. Despite national targets to reach carbon neutrality by 2050, oil and gas still make up over 85% of Japan’s primary energy supply. Domestic oil consumption remains high, with major refiners like Eneos, Idemitsu, and Cosmo Energy dominating supply to transportation, petrochemicals, and heavy industry.

These firms operate some of the largest and most complex refining infrastructure in Asia, with extensive downstream supply chains that are deeply embedded in Japan’s industrial economy. Eneos alone processes over 1.7 million barrels per day of crude oil across its network of refineries.

A Fork in the Road for Japan’s Climate Goals

The latest decisions from Japan’s oil giants underscore a fundamental challenge for climate policy: decarbonization is expensive, slow, and politically fragile. While Japan remains publicly committed to its 2050 net-zero pledge, the path forward now appears far more incremental—and conditional on technological breakthroughs or major policy shifts.

Investments in hydrogen and ammonia will continue, but they’ll no longer be the cornerstone of energy strategy. Instead, LNG and oil will remain the backbone of Japan’s energy system for the foreseeable future.

What Comes Next

Expect Japanese energy firms to pursue hybrid strategies, combining fossil fuel expansion with selective low-carbon projects tied to government subsidies or international joint ventures. Meanwhile, Japan’s Ministry of Economy, Trade and Industry (METI) may revisit incentive frameworks to keep climate efforts alive without alienating the country’s industrial base.

The pivot also presents an opening for U.S., Middle Eastern, and Southeast Asian producers to expand LNG exports to Japan, now that long-term fossil contracts are back in vogue.

In short, Japan’s energy policy is entering a pragmatic phase—less focused on declarations and more grounded in security, cost, and infrastructure realities. The ambition of a carbon-neutral society remains, but for now, fossil fuels are back in the driver's seat.
