As low-carbon and renewable fuel markets enter 2026, the global energy transition is moving into a new phase. The last several years were marked by ambitious targets, landmark regulations, and significant capital deployment. The coming year will be shaped by the implementation of existing policies and market execution. Across carbon markets, low-carbon fuels, and emerging energy systems, one message is consistent: credibility, flexibility, and operational readiness are becoming decisive factors for success.

Our experts share their views of what’s to come, highlighted in the article below, and linked here to view the 2026 Market Trends & Insights webinar.

European Carbon Markets: Implementation and Certification Readiness

European carbon markets are moving into a decisive implementation phase as policy focus shifts from setting new targets to delivering systems that balance decarbonization with competitiveness. The European Union (EU) Emissions Trading System (ETS) remains central, and will be reformed in 2026, addressing key topics including aviation and maritime sectors, carbon-leakage-exposed industries, and the potential role of permanent carbon removals.

At the same time, the Carbon Border Adjustment Mechanism (CBAM) is transitioning toward full compliance, increasing demand for verified emissions data and defensible carbon accounting across supply chains. The EU is also advancing programs such as the Carbon Removal Certification Framework (CRCF) that emphasize measurable, verifiable, and credible outcomes before market recognition.

Critically, 2026 will bring heightened scrutiny of sustainability certification systems operating under the Renewable Energy Directive (RED). Increased oversight of certification bodies, accreditation requirements, and lifecycle analysis methodologies reflects a broader push for consistency and transparency. In this environment, recognized certification schemes such as the Roundtable on Sustainable Biomaterials (RSB) play a central role in enabling compliant access to European fuel and carbon markets through robust, third-party verification.

Together, these developments signal a clear direction: success in European carbon markets will increasingly depend on execution, data quality, and credible certification—not new regulatory ambition.

Voluntary Carbon Markets: From Speed to Scrutiny

Voluntary carbon markets (VCMs) continue to grow, but under increasingly rigorous conditions. The market is shifting away from rapid, spot-based credit purchases toward longer, more structured procurement processes that emphasize quality, durability, and verification. Offtake agreements are becoming more common, replacing spot transactionspurchases with multi-year commitments that entail more rigorous due diligence across registries, verification bodies, credit rating agencies, investors, and buyers.

At the same time, demand is expanding beyond traditional corporate purchasers, with state and subnational compliance programs accounting for a growing share of voluntary credit use. While this evolution is increasing complexity for project developers, particularly around Article 6 eligibility, credit ratings, and co-benefit requirements, it is also contributing to a more resilient and liquid market where credibility and verified outcomes are essential to securing long-term financing and buyer confidence.

Renewable Natural Gas: A More Disciplined Growth Phase

Renewable natural gas (RNG) markets are entering a phase of operational adolescence. While demand from compliance markets such as the Renewable Fuel Standard (RFS) and state-level low-carbon fuel programs such as the California Low Carbon Fuel Standard remains supportive, project developers are navigating longer timelines and more disciplined capital markets.

We’re seeing pathways into Canadian Fuel Regulation (CFR) progressing, with numerous RNG projects seeking to enter that market. The California Air Resources Board (CARB) is aiming to reduce project approval timelines.

As facilities come online, the focus is shifting from development to performance: optimizing operations, benchmarking against peer facilities, and managing long-term compliance obligations. At the same time, access to experienced operational and compliance talent is emerging as a constraint, particularly as the sector scales.

For RNG producers, success in 2026 will increasingly depend on realistic project planning, operational excellence, and the ability to demonstrate consistent performance over time.

Ethanol and Biodiesel: Building Flexibility into Strategy

Ethanol and biodiesel producers are facing a period of structural uncertainty driven by evolving policy frameworks, including federal and state incentive programs and emerging voluntary markets. While new guidance continues to emerge, many rules remain subject to interpretation and revision.

In response, producers should be rethinking how they position assets for the future. Ethanol is evolving beyond its traditional role as a gasoline blendstock to serve as a platform molecule for sustainable aviation fuel, chemicals, and other low-carbon applications.

Rather than betting on a single pathway, many facilities are pursuing layered decarbonization strategies that combine near-term operational improvements with longer-term investments, such as carbon capture, RNG integration, and process redesigns. This approach creates optionality, allowing producers to adapt as markets and regulations evolve.

Renewable Diesel and SAF: Demand Is Clear, Constraints Remain

Renewable diesel and sustainable aviation fuel (SAF) remain among the most critical decarbonization tools for transportation and aviation. Demand is growing rapidly, driven by regulatory mandates and corporate climate commitments, and is expected to continue rising throughout the decade.

However, supply constraints persist. Feedstock availability, competing uses, trade restrictions, and fragmented regulatory frameworks continue to slow scale-up. While new production pathways such as alcohol-to-jet and power-to-liquids offer long-term promise, they require significant time, capital, and regulatory alignment to reach commercial scale.

In the near term, regulatory complexity, particularly around feedstock eligibility, life-cycle analysis (LCA), and verification, remains one of the most significant challenges for market participants operating across jurisdictions.

Hydrogen: Momentum Tempered by Practical Constraints

Clean hydrogen continues to attract global investment, particularly in regions focused on energy security and long-term decarbonization. While Europe and Asia are advancing rapidly, hydrogen project development in the U.S. and Canada face unique challenges, including high electricity prices, grid constraints, and compressed timelines for federal incentives.

In the near term, developers are increasingly focused on early-stage technical due diligence, lifecycle emissions modeling, and evaluation of multiple incentive pathways. These steps are essential to maintaining project viability in a shifting policy environment.

In the long term, EU investment in hydrogen infrastructure, such as fueling stations and pipelines, points to opportunities for steady growth. In the U.S., growing data centers, vehicle electrification, and industrial energy demand provide a growth trajectory for low-carbon intensity hydrogen from a variety of production pathways.

What 2026 Signals for Market Participants

Across all markets, a common theme is emerging: the transition is no longer about ambition alone. It is about delivering measurable, verifiable results under increasingly rigorous standards.

Organizations that invest early in LCA, compliance planning, and data transparency are better positioned to manage uncertainty and respond to changing market signals. Flexibility and optionality are becoming core components of project strategy, not as a hedge, but as a requirement for long-term resilience.

As 2026 approaches, carbon and fuel markets will continue to grow, but success will favor those who can navigate complexity, demonstrate credibility, and execute with discipline.

Understanding the regulatory frameworks that shape U.S. and state-level carbon markets is essential for anyone working in sustainability, compliance, or renewable fuel development. If you’re looking to build these critical skills and regulatory literacy, check out our EcoForums training series.
