UNFC and the structure beneath global energy systems

May 5, 2026

VIVACE had the pleasure to participate in the United Nations 17th session of the Expert Group on Resource Management in Geneva in late April, where implementation of the United Nations Framework Classification for Resources (UNFC) was reviewed alongside developments in critical minerals, energy transition systems and global resource governance.

The tone of the discussions reflected a framework that has moved beyond early standardisation debates. UNFC is now operating as a shared interpretive structure across countries that otherwise rely on incompatible resource accounting systems. Its relevance has grown with energy transition policy, where comparability between oil, gas, minerals and emerging energy vectors has become operational rather than theoretical.

UNFC structures resources across three dimensions: geological confidence (G), project maturity (F) and economic viability (E). An E1F1G1 classification describes full alignment across these dimensions, where geology, engineering and market conditions converge into production reality. Other combinations describe varying degrees of partial alignment across the same space.

Most conventional reporting compresses this structure into single figures such as reserves or resources. Global oil reserves, for example, are typically reported at 1.6 to 1.8 trillion barrels, with more than 80 percent of proven conventional reserves concentrated in OPEC+ countries including Venezuela, Saudi Arabia, Canada, Iran and Iraq. That aggregation conceals how unevenly the underlying system is distributed across development, economics and geological certainty.

Oil and gas and the layered nature of “proven” reserves

Within UNFC terms, the proven reserve category maps closely to the intersection of E1, F1 and G1 conditions. These are assets with high geological confidence, developed or sanctioned infrastructure and economic viability under current market conditions.

This intersection represents only a fraction of the broader hydrocarbon system. E2 and E3 categories capture resources that remain geologically defined but economically conditional, while F2 and F3 reflect projects in appraisal, sanctioning or early development stages.

Market dynamics reflect this structure. The International Energy Agency has projected scenarios in which global supply growth exceeds demand by several million barrels per day in the mid-2020s, even as investment remains uneven across regions and upstream replacement rates diverge. The same system can therefore register surplus conditions and tightness simultaneously depending on which layer is being observed.

Coal and the gradual reclassification of economic space

Coal production remains structurally significant at 7 to 8 billion tonnes annually. Large geological basins remain well defined in G1 and G2 categories across major producing regions.

A growing share of these resources now sits in E2 and E3 classifications. Carbon pricing regimes, tightening financial conditions and demand substitution in electricity generation continue to shift coal assets out of economically viable categories despite geological stability.

This creates a divergence between physical abundance and investment relevance. Geological inventories remain extensive while portions of the system exit current economic frameworks.

Critical minerals and the bottleneck in project conversion

Critical minerals introduce a different structural constraint. Lithium demand has increased by roughly 30 percent year on year in recent IEA estimates, while nickel, cobalt and graphite continue to grow at mid single digit rates driven by electrification and grid expansion.

Supply chains remain highly concentrated. The top three producing countries account for roughly 80 to 86 percent of refined output across key energy transition minerals, with China and Indonesia central to processing and refining capacity. China remains the leading refiner across a majority of strategic energy-related minerals tracked globally.

UNFC highlights that geological endowment is relatively broad across G1 and G2 categories for many of these materials. The binding constraint emerges in the F dimension, where permitting timelines, infrastructure readiness and capital coordination determine whether projects move from identified deposits into production.

Price behaviour reflects this structure. Lithium prices fell by more than 80 percent from their 2022 peak despite sustained long-term demand growth, reflecting rapid supply expansion and delayed demand absorption across parts of the system.

Geopolitics and control over transition pathways

Energy geopolitics operates across multiple layers of control. Traditional analysis focuses on reserve ownership, but UNFC brings attention to control over transitions between states.

In oil and gas systems, influence remains concentrated in E1F1G1 assets due to their immediate integration into global supply chains. In critical minerals, influence increasingly emerges through control of F-stage progression, including permitting systems, industrial policy coordination and infrastructure deployment capacity.

Policy developments reflect this shift. Export controls on critical minerals and processing technologies have expanded across multiple jurisdictions, while major economies including the United States and European Union have introduced strategies focused on accelerating domestic project pipelines alongside supply chain diversification.

The strategic question increasingly centres on how quickly resources can move through system layers rather than where they are located in geological terms alone.

Comparison with PRMS, CRIRSCO and national classification systems

Existing classification systems operate as sector-specific structures that UNFC connects into a broader coordinate framework.

The SPE PRMS system in oil and gas links geological uncertainty to financial valuation through categories such as proved, probable and possible reserves. It aligns closely with the E1F1G1 region of UNFC and functions effectively within hydrocarbon investment frameworks, where reserve classification directly informs capital allocation.

CRIRSCO-based systems such as JORC and NI 43-101 serve a similar function in mining, defining inferred, indicated and measured resources with strong emphasis on geological certainty and investor protection. These systems are widely adopted across listed mining jurisdictions but remain primarily focused on subsurface confidence rather than full system readiness.

National approaches vary. The United States combines PRMS with SEC disclosure requirements, China integrates resource classification into centrally coordinated industrial policy frameworks and several legacy systems retain geology-heavy hierarchical reporting structures with limited integration across sectors.

UNFC operates as a translation layer across these systems, allowing oil, gas, coal and mineral resources to be expressed within a shared structure that preserves sector detail while enabling cross-system comparison.

The structure behind global energy systems

UNFC provides a framework for reading energy systems across their internal structure rather than through aggregated endpoints. Only a portion of global resources exist in fully aligned configurations at any moment, while a larger share distributes across intermediate states shaped by geological certainty, project development and economic conditions.

Conventional reporting captures the aligned endpoints, particularly proven reserves and operational production. UNFC makes the intermediate layers visible and comparable across sectors that are otherwise difficult to reconcile in a single analytical frame.

Global energy dynamics follow from this distribution. System outcomes depend on how resources sit across these states and how efficiently movement occurs between them under conditions shaped by markets, infrastructure and policy constraints.
