The Global Emission Control Catalysts Market is primarily segmented into several key types, each designed to address specific operational demands and performance criteria.
-
Diesel oxidation catalysts:
Diesel oxidation catalysts occupy a mature and widely deployed position in the emission control catalysts market, especially in on-road and off-road diesel engines for commercial vehicles, construction machinery, and agricultural equipment. These catalysts primarily target carbon monoxide, unburned hydrocarbons, and soluble organic fractions of particulate matter, making them a foundational technology in regulated diesel powertrains. In terms of penetration, a significant portion of modern diesel vehicles in North America, Europe, and parts of Asia-Pacific already rely on diesel oxidation catalysts as part of their standard aftertreatment system architecture.
The competitive advantage of diesel oxidation catalysts lies in their relatively low cost per installed kilowatt and their high conversion efficiencies, which often exceed 90.00% for carbon monoxide and hydrocarbon removal under optimized operating conditions. Their simple flow-through design, compact packaging, and compatibility with existing exhaust layouts reduce integration complexity and minimize backpressure penalties compared to more complex filter-based systems. This combination of efficiency and ease of integration allows OEMs to meet tightening emission standards while controlling total cost of ownership and maintaining fuel economy.
The principal growth catalyst for diesel oxidation catalysts is the ongoing enforcement of stringent emission norms in emerging markets, where older diesel fleets are being replaced with vehicles that must comply with Euro VI–equivalent or China VI standards. Additionally, the expansion of regulated segments such as diesel generator sets for critical infrastructure and marine auxiliary engines is reinforcing demand. Although long-term electrification may limit growth in light-duty segments, medium- and heavy-duty diesel applications in logistics, mining, and remote power generation continue to sustain robust demand for advanced oxidation catalyst formulations with improved sulfur tolerance and durability.
-
Three-way catalysts:
Three-way catalysts represent one of the most established and high-volume segments within the emission control catalysts market, particularly for gasoline-powered passenger cars and light commercial vehicles. These systems simultaneously convert carbon monoxide, hydrocarbons, and nitrogen oxides when the engine operates at stoichiometric air-fuel ratios, making them indispensable in markets with dense automotive populations. In major automotive regions such as North America, Europe, and East Asia, three-way catalysts are installed on the vast majority of gasoline vehicles, giving this segment a deep and entrenched installed base.
The competitive differentiation of three-way catalysts stems from their ability to achieve conversion efficiencies that can exceed 95.00% for regulated pollutants under optimal conditions, while maintaining durability over service lifetimes exceeding 160,000.00 kilometers. Advanced formulations using high-dispersion precious metals and optimized washcoat architectures provide strong thermal stability and resistance to poisoning, which helps automakers reduce precious metal loading and overall catalyst cost per vehicle. This high-efficiency, long-life performance has allowed three-way catalysts to remain competitive even as regulatory test cycles become more demanding and real-driving emissions protocols gain prominence.
The main growth driver for three-way catalysts is the continued production of internal combustion engine vehicles in large emerging markets, combined with the adoption of more rigorous emission standards such as Real Driving Emissions and tighter particulate number limits. Hybrid powertrains that pair gasoline engines with electrification also support demand, as these vehicles still require high-performance exhaust aftertreatment to comply with fleet-wide CO2 and pollutant caps. As OEMs optimize engines for higher thermal efficiency, new three-way catalyst formulations tailored to faster light-off and broader temperature windows are gaining traction, reinforcing the segment’s relevance across the forecast horizon.
-
Selective catalytic reduction catalysts:
Selective catalytic reduction catalysts form a rapidly expanding and technologically advanced segment of the emission control catalysts market, particularly in heavy-duty diesel vehicles, marine engines, and industrial stationary sources. These systems use a reductant such as urea-derived ammonia to convert nitrogen oxides into nitrogen and water, enabling compliance with some of the most stringent NOx limits currently in force. SCR technology has become standard on most Euro VI heavy-duty trucks and is increasingly mandated for off-road machinery and large compression-ignition engines, driving strong baseline demand.
The competitive advantage of SCR catalysts lies in their ability to achieve NOx reduction efficiencies in the range of 85.00% to 95.00% across a broad engine operating map, which is considerably higher than what can be achieved by engine tuning alone. By shifting a portion of NOx reduction from in-cylinder measures to the aftertreatment system, SCR enables engine manufacturers to calibrate for improved fuel efficiency, often delivering fuel savings of 3.00% to 5.00% compared to non-SCR strategies. This dual benefit of regulatory compliance and lower fuel consumption makes SCR catalysts highly attractive for fleet operators focused on lifecycle cost optimization.
The primary growth catalyst for SCR catalysts is the tightening of global NOx emission regulations across on-road, off-road, and marine sectors, including the move toward ultra-low NOx standards in some jurisdictions. The extension of SCR technology into medium-duty vehicles, locomotives, and high-horsepower applications further expands the addressable market. In addition, adoption in industrial boilers and power plants to meet air quality targets is driving demand for large-scale SCR reactors, reinforcing this segment’s role as a critical technology within the global emission control framework.
-
Diesel particulate filter catalysts:
Diesel particulate filter catalysts constitute a high-impact segment focused on the reduction of particulate mass and particle number emissions from diesel engines. These systems combine wall-flow filter substrates with catalytic coatings to trap and oxidize soot, thereby meeting extremely low particulate limits enforced under modern emission standards. They are now standard equipment on most new on-road diesel vehicles in advanced markets and are increasingly specified for off-road applications in construction, agriculture, and material handling equipment.
The competitive strength of diesel particulate filter catalysts lies in their ability to capture more than 90.00% of particulate mass and an even higher fraction of particle number, while catalytic coatings enable passive and active regeneration to maintain filter functionality. By integrating oxidation and filtration functions, these catalysts reduce the need for auxiliary fuel burners and limit thermal stress on the substrate, resulting in longer service intervals and lower maintenance costs. The combination of high filtration efficiency and controlled regeneration performance provides OEMs with a reliable route to comply with stringent particle number regulations without compromising engine output.
The key growth driver for diesel particulate filter catalysts is the global push to mitigate health impacts associated with ultrafine particulate emissions, reflected in progressively tighter emission standards and urban low-emission zones. Growing adoption of retrofit DPF systems on legacy fleets in densely populated regions also contributes to incremental demand. Furthermore, the integration of DPF catalysts with SCR-on-filter or dual-layer architectures is creating opportunities for multifunctional systems that address both NOx and particulate emissions, enhancing system value and market penetration across diverse diesel applications.
-
Lean NOx trap catalysts:
Lean NOx trap catalysts occupy a specialized niche within the emission control catalysts market, primarily serving lean-burn gasoline engines and some light-duty diesel applications where packaging or duty-cycle constraints limit the use of full-scale SCR systems. These catalysts adsorb nitrogen oxides during lean operation and periodically release and reduce them during short rich-burn events, enabling compliance with stringent NOx limits for specific vehicle platforms. Their deployment is most prevalent in small and mid-size vehicles where space, cost, or temperature profiles favor lean NOx trap technology.
The competitive advantage of lean NOx trap catalysts lies in their compactness and integration simplicity, since they do not require a separate reductant dosing system or urea infrastructure. Under well-managed regeneration strategies, lean NOx traps can achieve NOx conversion efficiencies of 70.00% to 85.00% over relevant driving cycles, providing a viable alternative when SCR implementation would be cost-prohibitive or operationally complex. This ability to combine NOx control with simpler hardware makes lean NOx traps attractive for automakers seeking optimized solutions in selected segments.
The main growth catalyst for lean NOx trap catalysts is the development of advanced lean-burn gasoline and mild hybrid engines that aim for high thermal efficiency while still meeting stringent emission standards. Regulatory focus on real-world NOx performance is encouraging refinements in LNT formulations to improve durability and sulfur tolerance, which helps sustain their applicability. While competition from compact SCR systems is increasing, lean NOx traps continue to find opportunities in platforms where tight integration, reduced weight, and minimal additional components are prioritized for performance and cost reasons.
-
Oxidation catalysts for stationary sources:
Oxidation catalysts for stationary sources represent a critical segment targeting emissions from industrial facilities, gas turbines, engines used in power generation, and process heaters. These catalysts focus on reducing carbon monoxide, volatile organic compounds, and in some cases organic hazardous air pollutants, contributing to compliance with local and national air quality standards. They are widely installed in combined heat and power plants, pipeline compressor stations, and industrial boilers, where continuous-duty operation and high uptime requirements are standard.
The competitive edge of oxidation catalysts for stationary sources stems from their ability to deliver high conversion efficiencies, often above 90.00% for carbon monoxide and hydrocarbons, over long operating periods and under variable load conditions. Catalyst designs optimized for high space velocity and robust thermal stability allow operators to treat large exhaust volumes without significant pressure drop or excessive catalyst volume. This combination of high throughput capacity and long service life reduces operating costs per megawatt-hour generated, making these catalysts economically attractive for industrial asset operators.
The primary growth driver for oxidation catalysts in stationary applications is the global shift toward stricter emissions permits for power and industrial installations, including requirements associated with new natural gas–fired capacity and distributed generation. As many countries retire older high-emission plants and invest in cleaner gas-based systems, demand for reliable oxidation catalyst solutions is scaling accordingly. In addition, the expansion of data centers and critical infrastructure with on-site backup generation is creating new use cases where consistent emissions performance and regulatory compliance are fundamental procurement criteria.
-
Ammonia slip catalysts:
Ammonia slip catalysts occupy a complementary but strategically important role in advanced SCR-based emission control architectures, targeting residual ammonia that passes through the primary NOx reduction stage. These catalysts are increasingly specified in heavy-duty vehicles, large stationary SCR systems, and marine installations where tight control of ammonia slip is mandated to prevent secondary environmental and health impacts. As SCR penetration rises, the adoption of ammonia slip catalysts grows in parallel, cementing their position as a critical safeguard technology in integrated aftertreatment systems.
The competitive advantage of ammonia slip catalysts lies in their ability to convert excess ammonia into nitrogen and water with minimal impact on NOx performance, maintaining low outlet ammonia concentrations often below 5.00 parts per million when correctly sized and integrated. Advanced formulations can handle high space velocities and fluctuating exhaust conditions while minimizing unwanted byproducts such as nitrous oxide. This precise control over residual ammonia allows operators to run SCR systems closer to optimal dosing rates, maximizing NOx reduction efficiency without breaching ammonia emission limits.
The key growth catalyst for ammonia slip catalysts is the global trend toward high-performance SCR systems operating at elevated dosing rates to meet ultra-low NOx targets in both mobile and stationary sectors. Regulatory frameworks in many regions are specifying explicit ammonia emission limits at stack or tailpipe outlets, compelling plant operators and vehicle manufacturers to integrate dedicated slip control stages. As more large-scale industrial and marine SCR units come online, demand for robust, long-life ammonia slip catalysts is expected to expand, reinforcing their role in complete emission control solutions.

Market By Application
The Global Emission Control Catalysts Market is segmented by several key applications, each delivering distinct operational outcomes for specific industries.
-
Light-duty vehicles:
Light-duty vehicles represent one of the largest and most visible applications for emission control catalysts, encompassing passenger cars, SUVs, and small commercial vans powered by gasoline, diesel, and hybrid powertrains. The core business objective in this segment is to achieve compliance with stringent tailpipe regulations while preserving vehicle performance and fuel economy, as non-compliance can block market access in major regions. Catalyst systems in light-duty vehicles are now standard, with virtually all new gasoline cars in developed markets equipped with high-efficiency three-way catalysts.
Adoption in light-duty vehicles is justified by the ability of emission control catalysts to reduce regulated pollutants by more than 90.00% relative to uncontrolled engines, while maintaining acceptable backpressure and drivability. Automakers typically achieve regulatory compliance with minimal impact on fuel consumption, and in many cases emissions hardware contributes to residual value by enabling longer warranty coverage and fleet-wide CO2 strategy optimization. The payback is realized through avoidance of penalties, preservation of brand reputation, and sustained access to high-volume markets, where even a 1.00% improvement in fleet compliance can translate into substantial financial benefits.
The primary growth catalyst in the light-duty segment is the progressive tightening of emission and real-driving standards across Europe, China, India, and other high-growth automotive markets. Increasing penetration of turbocharged gasoline direct injection and hybrid architectures requires more sophisticated catalyst designs with faster light-off and improved low-temperature performance, supporting ongoing technology upgrades. Additionally, the huge installed base, combined with gradual electrification rather than an immediate transition, ensures that light-duty vehicles continue to generate steady demand for advanced emission control catalysts over the medium term.
-
Heavy-duty vehicles:
Heavy-duty vehicles, including long-haul trucks, buses, and large commercial vehicles, constitute a critical application where emission control catalysts enable operators to meet strict NOx and particulate limits under demanding duty cycles. The business objective in this segment is to balance regulatory compliance with operational efficiency, as these vehicles often run high annual mileages and generate significant revenue per asset. Robust aftertreatment systems combining diesel oxidation catalysts, diesel particulate filters, and selective catalytic reduction units are now standard in most new heavy-duty platforms in advanced markets.
Adoption in heavy-duty vehicles is driven by the ability of integrated catalyst systems to achieve NOx reduction levels of 85.00% to 95.00% and particulate mass reductions above 90.00%, while supporting fuel efficiency gains compared to purely in-cylinder control strategies. Fleet operators often realize fuel savings of 3.00% to 5.00% when SCR allows engines to operate in more efficient combustion regimes, which can recover the incremental cost of advanced aftertreatment within a few years of operation. Reduced downtime due to longer service intervals and stable emission performance over high mileage further strengthens the return on investment for fleet owners.
The main growth catalyst for emission control catalysts in heavy-duty vehicles is the rollout of ultra-low NOx standards and advanced emission frameworks in North America, Europe, and parts of Asia-Pacific. Urban air quality initiatives, low-emission zones, and green corridor policies are putting pressure on logistics companies to modernize fleets and adopt cleaner vehicles. Additionally, expanding freight demand in emerging economies, combined with domestic regulatory upgrades, is increasing the penetration of high-performance catalyst systems in new heavy-duty platforms and retrofit programs.
-
Off-road vehicles and equipment:
Off-road vehicles and equipment, such as agricultural tractors, construction loaders, forestry machinery, and material handling units, form a rapidly formalizing application area for emission control catalysts. The core business objective is to reduce emissions from engines that operate in variable and often harsh conditions while maintaining torque, reliability, and long service life. Historically less regulated than on-road fleets, these segments have experienced a shift toward advanced emission stages that require diesel oxidation catalysts, diesel particulate filters, and in some cases SCR systems.
Adoption is justified by the ability of catalyst-equipped off-road engines to cut particulate and NOx emissions by more than 80.00% compared with older non-compliant models, significantly improving local air quality at worksites and agricultural fields. Equipment owners benefit from longer engine life due to cleaner combustion environments and reduced soot loading, which can lower unplanned downtime by an estimated 10.00% to 20.00% over the machine’s life. In addition, compliance with newer standards expands equipment export potential, allowing manufacturers to access regulated markets that demand certified emission performance.
The primary growth catalyst is the global alignment of off-road emission regulations with on-road standards, such as Stage V in Europe and similar frameworks in North America and Asia. Large infrastructure programs, mechanization of agriculture in emerging economies, and increased use of rental fleets are driving replacement of older equipment with modern, emissions-compliant models. As OEMs standardize engine platforms and aftertreatment solutions globally, demand for durable, vibration-resistant emission control catalysts in off-road applications continues to rise.
-
Power generation:
Power generation applications encompass gas and diesel generator sets, gas turbines, and reciprocating engines used for baseload, peaking, and backup power. The business objective is to maintain continuous, reliable electricity production while meeting stack emission limits set by environmental permits and grid codes. Emission control catalysts installed on these units primarily target NOx, carbon monoxide, and unburned hydrocarbons to ensure compliance during sustained operation and frequent start-stop cycles.
Adoption is justified because oxidation catalysts and SCR systems can reduce NOx emissions by up to 90.00% and carbon monoxide emissions by more than 90.00%, allowing operators to stay within permitted thresholds without major changes to combustor design. This enables power plant owners and distributed generation providers to maximize utilization hours without triggering regulatory penalties or curtailment. For many projects, integrating catalysts into the design phase results in predictable compliance costs and can shorten permitting timelines by demonstrating robust emission mitigation measures.
The main growth driver in power generation is the global move toward cleaner gas-fired and high-efficiency distributed power, often sited close to urban centers where emission limits are tight. Expansion of data centers, hospitals, and critical infrastructure with on-site backup and combined heat and power plants further increases the installed base requiring high-performance catalysts. Additionally, retrofit requirements for existing plants facing stricter permits are creating recurring demand for upgraded catalyst systems, particularly in regions pursuing aggressive air quality improvement programs.
-
Industrial manufacturing:
Industrial manufacturing applications include exhaust streams from furnaces, kilns, dryers, and process heaters in sectors such as metals, glass, cement, and food processing. The core business objective is to maintain production throughput while controlling emissions of NOx, volatile organic compounds, and carbon monoxide to meet regulatory and corporate environmental targets. Emission control catalysts in these environments help operators keep emissions within consent limits without frequent interruptions to production lines.
Adoption is driven by the ability of catalytic systems to reduce key pollutants by 80.00% to 95.00%, depending on the process and catalyst design, while operating at high space velocities suitable for large industrial flows. By enabling compliance without extensive flue gas recirculation or costly process redesigns, catalysts can preserve or even improve plant productivity. Manufacturers benefit from reduced risk of production curtailment, lower environmental fees, and improved community relations, which collectively support a favorable payback profile for catalyst investments.
The primary growth catalyst in industrial manufacturing is the tightening of plant-level emission caps, driven by national regulations and corporate decarbonization strategies that include local air pollutants. As companies pursue certifications and sustainability reporting, reliable emission control becomes a prerequisite for maintaining contracts with environmentally conscious customers. Furthermore, modernization of legacy industrial facilities in emerging economies, often supported by international funding mechanisms, is stimulating demand for industrial-grade emission control catalysts.
-
Chemical and petrochemical processing:
Chemical and petrochemical processing plants generate complex exhaust streams from crackers, reformers, flares, and process vents, making emission control catalysts essential for managing NOx, VOCs, and hazardous air pollutants. The core business objective is to maintain safe and continuous operation of high-value process units while ensuring that emissions remain within strict regulatory thresholds that often apply at both unit and site levels. Catalyst systems in this sector must perform reliably under high temperatures and challenging gas compositions.
Adoption is justified by the capacity of tailored catalyst formulations to achieve VOC destruction efficiencies above 95.00% and substantial NOx reductions without compromising process stability. By installing catalytic units in key exhaust lines, operators can avoid costly process derating or flare overuse, thereby preserving throughput and product yields. The economic value is reinforced by reduced risk of non-compliance events, which in this sector can lead to significant fines and unscheduled shutdowns with multimillion-dollar revenue impacts.
The primary growth driver is the expansion and upgrading of petrochemical complexes, particularly in the Middle East, Asia-Pacific, and the United States, where new plants are designed around best-available control technology. Emerging rules on hazardous air pollutants and tighter monitoring through continuous emission systems are compelling operators to adopt more advanced and stable catalyst solutions. In addition, integration of emission control into broader environmental, social, and governance programs is pushing leading chemical producers to standardize high-performance catalysts across their global asset base.
-
Marine and shipping:
Marine and shipping applications cover main propulsion engines and auxiliary power units on oceangoing vessels, coastal ships, and inland waterway fleets. The business objective is to reduce NOx, SOx, particulate matter, and, in some cases, unburned hydrocarbons to comply with emission control area standards and international maritime regulations. Emission control catalysts, often combined with scrubbers or low-sulfur fuels, are increasingly used to bring engines into compliance without sacrificing voyage range or operational flexibility.
Adoption in marine and shipping is justified by the ability of SCR units and oxidation catalysts to cut NOx emissions by up to 90.00% and reduce hydrocarbons and carbon monoxide by more than 80.00%, enabling vessels to enter regulated ports and emission control areas. For shipowners, installing catalysts can protect charter rates and route options, avoiding detours or penalties that would erode profitability. While capital expenditure is significant, the payback can be realized over several years through access to premium routes, lower port fees, and extended asset life under compliant operation.
The main growth catalyst is the continued enforcement and geographic expansion of maritime emission control areas and tiered NOx standards for newbuild and retrofitted vessels. As global trade rebounds and fleet renewal accelerates, shipyards and engine manufacturers are integrating catalyst-ready exhaust systems as standard offerings. Additionally, the shift toward LNG and other alternative marine fuels still requires robust emission control to manage NOx and methane slip, creating further opportunities for high-capacity marine catalyst systems.

-
Opportunities:
The Global Emission Control Catalysts market has significant growth headroom in emerging economies where motorization rates are rising and emission norms are tightening toward Euro 6-equivalent standards. There are increasing opportunities in retrofit programs for older diesel truck fleets, marine engines, and industrial boilers that must meet new ambient air quality targets in large cities. Advanced low-temperature and cold-start catalysts, gasoline particulate filters, and ammonia slip catalysts offer additional value pools as OEMs optimize engine calibration to balance CO2 and pollutant emissions. Furthermore, the push for circular economy models is expanding demand for closed-loop PGM recycling and secondary sourcing, opening new service-based revenue streams for catalyst suppliers that can offer take-back, refining, and re-manufacturing solutions with certified sustainability performance and reduced lifecycle emissions.
-
Threats:
The most significant threat to the Emission Control Catalysts market comes from accelerated adoption of battery electric vehicles and fuel cell electric platforms, which bypass traditional exhaust aftertreatment entirely in light-duty segments. Policy measures such as zero-emission vehicle mandates, city-level combustion bans, and aggressive fleet electrification targets can compress long-term demand for catalytic converters and diesel aftertreatment systems. In parallel, competitive pressure from alternative technologies, including advanced EGR strategies, dual-fuel engines, and non-catalytic industrial abatement solutions, can erode catalyst volumes in niche applications. Geopolitical instability and trade restrictions affecting platinum group metal mining regions also pose supply chain and cost risks, while increasingly stringent lifecycle and sustainability requirements may penalize producers that cannot demonstrate low-carbon, ethically sourced PGM supply and high recycling rates.
Future Outlook and Predictions
The global Emission Control Catalysts market is expected to expand steadily over the next decade, anchored by a baseline compound annual growth rate of 6.40 percent and progression from a market size of USD 31,20 Billion in 2025 to USD 48,10 Billion by 2032. Over the next 5–10 years, value growth will outpace pure volume growth as regulatory complexity increases and catalyst systems become more sophisticated, particularly in diesel aftertreatment, gasoline particulate filtration, and industrial flue gas treatment. While light-duty internal combustion engines will gradually lose share to electrified powertrains in developed markets, demand from heavy-duty on-road, off-road, marine, and stationary sources will sustain a sizeable emissions control catalysts base.
Regulation-driven demand will remain the primary engine of market expansion. The phased introduction of Euro 7 in Europe, China 7 in China, and progressively tighter EPA and CARB standards in North America will force higher conversion efficiencies, longer durability, and lower cold-start emissions. These requirements will push OEMs toward multi-brick systems that combine diesel oxidation catalysts, coated diesel particulate filters, selective catalytic reduction units, and ammonia slip catalysts in integrated modules. Emerging economies in Asia, Latin America, and the Middle East are expected to converge toward Euro 6-equivalent norms, creating a second wave of volume growth as fleets upgrade from minimal or no aftertreatment.
Technological evolution will focus on low-temperature activity, precious metal thrift, and advanced washcoat architectures. Suppliers will intensify R&D around nanoporous structures, mixed metal oxides, and novel zeolites to meet stricter NOx and particulate limits while reducing platinum group metal content per kilowatt. Cold-start performance for gasoline engines will be improved through close-coupled catalysts, electrically heated catalysts, and innovative substrate geometries that achieve light-off faster. In parallel, industrial emission control catalysts for power plants, refineries, and chemical complexes will adopt more robust formulations to handle variable fuels, higher sulfur, and transient operating profiles.
Electrification will not eliminate demand but will reshape the segment mix and competitive landscape. Battery electric vehicles will erode catalyst volumes in small and midsize passenger cars, especially in Europe and parts of China, yet heavy-duty trucks, construction machinery, mining equipment, and marine engines will continue to depend on advanced aftertreatment beyond 2030. This will drive consolidation toward global players with scale in platinum group metal sourcing, high-throughput coating capacity, and digital-enabled application engineering, while niche specialists pivot toward retrofit programs, off-road applications, and high-temperature industrial abatement systems.
Circular economy and sustainability imperatives will become a central strategic theme for emission control catalysts suppliers. Over the next decade, a significant portion of platinum, palladium, and rhodium demand is expected to be met through closed-loop recycling from end-of-life catalytic converters and industrial catalysts, reducing exposure to mining volatility and geopolitical disruptions. Companies that integrate take-back logistics, advanced refining, and transparent ESG reporting into their catalyst offerings will secure long-term contracts with OEMs and industrial operators that must document Scope 3 emission reductions and ethical sourcing of critical materials.
