Mining and Metals industry drives 11 percent of global emissions

The global mining and metals industry is currently navigating a period of unprecedented scrutiny as the primary provider of the raw materials essential for the global energy transition. While the sector is the backbone of renewable energy infrastructure—supplying the lithium, copper, and nickel required for a low-carbon future—it simultaneously faces immense pressure to address its own significant carbon footprint.

A landmark 2026 analysis has finally quantified this impact, establishing a comprehensive baseline that places the industry as the sixth-largest contributor to global greenhouse gas emissions. For corporate stakeholders and investors, these findings underscore a critical inflection point: the need to rapidly decouple industrial production from carbon intensity to maintain regulatory compliance and market access in an increasingly climate-conscious global economy.

Establishing a comprehensive industry baseline for Scope 1 and 2 emissions

A landmark analysis by the International Council on Mining and Metals (ICMM) and Wood Mackenzie has provided the first definitive greenhouse gas (GHG) baseline for the global mining and metals sector. By examining 1,700 facilities across 14 commodities, the research clarifies the industry's precise contribution to global climate impacts as companies face increasing pressure to quantify their environmental footprints.

Distinguishing between raw extraction and downstream processing impacts

The research reveals that the combined mining and metals sector accounts for 11% of global greenhouse gas emissions, equivalent to approximately 6Gt CO2Eq. Within this total, a significant distinction exists between upstream and downstream activities: raw mining extraction accounts for 3% of global emissions, while downstream metal processing operations contribute the remaining 8%.

Operational data shows that 93% of the sector's emissions are Scope 1 releases generated directly on-site, totaling 5.5Gt CO2Eq. In contrast, indirect Scope 2 emissions from purchased electricity and energy account for just 7%, or 0.4Gt CO2Eq, highlighting that the majority of the sector's climate impact is within the direct operational control of producers.

Why steel and coal represent the majority of sectoral carbon footprints

Steel production, coal mining, and aluminum production collectively dominate the sector's environmental profile, accounting for 93% of its total Scope 1 and 2 emissions. Steel is the largest single emitter at 3.3Gt CO2Eq (55% of the sectoral total), primarily due to the carbon-intensive nature of blast furnace processes. Coal mining follows as the second-largest contributor at 23%, largely driven by fugitive methane emissions which account for 82% of all mining-specific Scope 1 and 2 releases.

Notably, the emissions profile for non-coal mining operations—including the extraction of critical minerals like copper, lithium, and cobalt—is significantly lower, representing just 0.54% of global greenhouse gas totals. This data helps differentiate the climate impact of the minerals essential for the energy transition from the high-volume bulk commodities that currently drive industrial emissions.

Identifying regional emission drivers across global hubs

The geographic distribution of mining and metals emissions is highly concentrated, with Asia generating 80% of the global sectoral output. This dominance reflects the region's dual role as a primary extraction center and the world's leading processing hub for the majority of industrial commodities.

While steel production is a major driver globally, regional profiles vary significantly based on local resources and industrial focus. For instance, in Europe, steel production accounts for a staggering 93% of regional mining and metals emissions. Conversely, in Africa and the Middle East, aluminum production represents 40% of emissions, while coal production is the primary driver in North America (41%) and Oceania (37%).

The role of Asia as the primary processing center

Asia's overwhelming share of emissions is largely tied to its refining and manufacturing capacity. Recent data suggests that China alone functions as the leading refiner for 19 of 20 critical minerals, cementing the region's position as the primary site for energy-intensive metal processing and its associated carbon footprint.

The energy intensity challenge of declining ore grades

As high-grade mineral deposits are depleted globally, the mining industry faces a compounding challenge where decreasing ore quality necessitates significantly higher energy consumption to extract equivalent volumes of metal. This trend creates a critical tension between the increasing demand for minerals and the industry's commitment to reducing its absolute carbon footprint.

Correlating falling mineral grades with rising operational energy use

The decline in ore grades across major commodities directly correlates with increased energy intensity, as operations must process larger volumes of waste rock to reach target minerals. This shift requires more extensive grinding, flotation, and concentration steps, each of which is energy-intensive and contributes to the sector's Scope 1 and 2 emissions profile.

Measuring the impact of lower-grade copper deposits

Copper serves as a primary example of this dynamic, with global average ore grades falling from approximately 1.6% in 1900 to less than 0.6% today. In Chile, a major global producer, copper operations saw energy consumption per unit of metal increase by 32% to 130% between 2001 and 2017, a trend driven almost entirely by the transition to processing lower-grade deposits.

Navigating the surge in critical mineral demand for the energy transition

The global transition to renewable energy is driving an unprecedented surge in demand, with projections indicating the world will require six times more mineral inputs by 2040 than it does today. Specifically, demand for copper is expected to rise by 70% by 2030, while lithium requirements could grow by over 400% in the same period to support battery and electric vehicle manufacturing.

This growth creates a "decarbonization paradox" where the materials needed to facilitate a low-carbon economy require an expansion of mining activities that may temporarily increase sectoral emissions. To address this, the industry is increasingly focused on improving emission intensity per unit of production, ensuring that the net climate benefit of these minerals outweighs the impact of their extraction.

Strategic pathways for mining decarbonization and technology substitution

To align with global climate targets, mining operators are adopting a dual-track strategy that balances immediate operational efficiencies with long-term structural shifts in energy and equipment. These pathways range from digital optimization and transitional fuels to the total electrification of heavy-duty haulage and primary metal processing.

Short term efficiency gains via AI and biofuel integration

In the immediate term, mining companies are leveraging data analytics, AI, and machine learning to optimize energy consumption and reduce their carbon footprint without requiring complete infrastructure overhauls. These technologies enable automated regulation of machinery speeds and predictive maintenance, while internal carbon pricing is increasingly used to guide daily operational decision-making toward lower-emission outcomes.

Transitioning away from pure diesel dependency involves shorter-term fixes such as the implementation of trolley assists for trucks and the adoption of biofuels. Additionally, advanced ore sorting technologies are being deployed to reject waste rock before it enters energy-intensive grinding and flotation stages, significantly improving the energy efficiency per unit of output.

Long term decarbonization through fleet electrification and hydrogen

The industry’s long-horizon goals focus on the total elimination of on-site fossil fuel power, primarily through the wholesale adoption of renewable energy. Many mining sites, often located in remote areas with high solar and wind potential, are ideally positioned for integrated renewable microgrids that can power both extraction and processing phases.

Full-scale re-fleeting with electric vehicles (EVs) represents a massive opportunity, as diesel combustion in haul trucks currently accounts for approximately 50% of direct mine-site emissions. For the heaviest machinery and long-haul requirements where battery capacity may be limited, hydrogen fuel cell technology is being explored as a critical alternative to traditional internal combustion engines.

Shifting toward electric arc furnaces in metal processing

Given that steel production dominates sectoral emissions, the transition from traditional blast furnaces to electric arc furnaces (EAF) offers the largest single decarbonization opportunity. EAF operations using recycled scrap steel can reduce production emissions by 65–75% depending on the carbon intensity of the local electricity grid. Furthermore, hydrogen-based direct reduction of iron ore is emerging as a long-term pathway to eliminate the chemical CO2 byproducts inherent in current iron oxide conversion.
