Current commitments from heavy industry sectors fall significantly short, targeting only a 60% emissions reduction by 2050 rather than full net-zero alignment[3][6]. This gap necessitates urgent, multifaceted strategies combining technological innovation, policy interventions, and international cooperation. Technological pathways include hydrogen-based steel production, carbon capture for cement, and industrial electrification, which could collectively abate 95% of emissions by 2050 but require unprecedented infrastructure investments[5][8][16]. Policy frameworks such as carbon contracts for difference and border adjustment mechanisms (CBAM) are critical for bridging the green premium, while sector-specific economic analyses reveal abatement costs ranging from $52–250/ton CO₂ depending on regional energy access and material efficiency[15][20][23]. Without accelerated action, emissions from hard-to-abate sectors could rise to 16 gigatons annually by 2050, undermining global climate targets[2][9][37].  \n\n## The Emissions Challenge and Decarbonization Imperative in Heavy Industry  \n\nHeavy industry sectors—iron and steel, cement, chemicals, and mining—collectively account for nearly one-third of global CO₂ emissions, characterized by energy intensity, process emissions, and capital-intensive infrastructure with long lifespans[6][14][31]. These sectors face unique hurdles: cement production releases CO₂ through limestone calcination (60% of sector emissions), while steel manufacturing relies on coal-based blast furnaces generating 1.8–2.5 tons of CO₂ per ton of steel[15][21]. Without intervention, industrial emissions could rise from 10 gigatons today to 16 gigatons by 2050, representing an increasing share of residual emissions as other sectors decarbonize[2][37]. The net-zero transition is further complicated by growing demand for industrial materials; global cement production must increase 80% by 2050 to support urbanization and renewable energy infrastructure, while steel demand could reach 2.2 billion tons annually[15][21][32]. Achieving net-zero thus requires transforming production processes without compromising economic accessibility, particularly in developing economies where industrial growth is most rapid[5][16].  \n\n### Classification of Heavy Industry Emissions Sources  \n\nEmissions in heavy industry derive from three primary sources: energy-related combustion (40–50%), industrial processes (30–40%), and fugitive releases (10–20%)[14][31]. In steelmaking, coal combustion for blast furnaces contributes 70% of emissions, with the remainder from coke production and ancillary processes[15][17]. Cement manufacturing emits CO₂ both from fuel combustion (40%) and chemical calcination (60%), where limestone (CaCO₃) decomposes into lime (CaO)[20][21]. Chemical production, particularly ammonia and methanol, relies on steam methane reforming of natural gas, emitting 1.5–2.5 tons of CO₂ per ton of product[32][35]. Mining emissions predominantly stem from diesel-powered mobile equipment (haul trucks, excavators) and ventilation systems, accounting for 1.1 gigatons annually[33][36]. Critically, 50–70% of industrial emissions originate from heat generation exceeding 400°C, which cannot be easily electrified with current technologies[7][34].  \n\n### Current Commitments and the Ambition Gap  \n\nDespite net-zero pledges from major corporations, aggregate industry commitments equate to only a 60% emissions reduction by 2050—falling substantially short of full decarbonization[3][6]. The iron and steel sector, for example, would emit 470 million tons of CO₂ annually by 2050 under current pledges, requiring $250 billion in carbon credits to achieve neutrality[15]. Cement producers face similar gaps; European plants could reduce emissions 78% at a carbon price of €100/ton but require €155/ton for near-full decarbonization[18][23]. This ambition gap stems from technology readiness, with 60% of required emissions reductions dependent on solutions still at prototype or demonstration phase[5][11]. For instance, hydrogen-based direct reduced iron (DRI) for steel exists at commercial scale but constitutes less than 1% of global production, while carbon capture for cement remains confined to pilot projects[8][17][22]. Without accelerated deployment, heavy industry risks locking in 30–40 years of emissions from new infrastructure built before 2030[16][24].  \n\n## Technological Pathways for Heavy Industry Decarbonization  \n\nDecarbonizing heavy industry necessitates deploying five interconnected technological pillars: energy efficiency, material efficiency, fuel switching, innovative processes, and carbon management. Energy efficiency improvements—such as waste heat recovery and advanced process controls—could deliver 10–15% near-term emissions reductions across sectors[2][7]. Material efficiency strategies, including industrial symbiosis and circular design, might reduce global steel demand 15–25% by 2050 through enhanced recycling and lightweighting[9][17]. Fuel switching to green hydrogen or biomass can address high-temperature heat needs, while electrification enables low-temperature processes[2][33][36]. For unavoidable emissions, carbon capture, utilization, and storage (CCUS) becomes essential, particularly in cement and chemicals[5][14][20]. Crucially, these technologies must be tailored to sector-specific constraints; hydrogen works for steel but faces cost barriers in cement, where CCUS dominates viable pathways[7][8][20].  \n\n### Energy and Material Efficiency Foundations  \n\nEnergy efficiency retrofits represent the most immediate decarbonization lever, reducing emissions 15–25% at negative or low abatement costs[2][7][9]. Technologies include variable-speed drives for motors (saving 20–30% electricity), regenerative burners capturing waste heat, and advanced sensors optimizing combustion[7][33]. Material efficiency—producing equivalent services with fewer resources—could abate 25% of industrial emissions by 2050 through lightweight steel in construction, reduced cement clinker ratios, and enhanced material cascading[5][9][17]. Steel recycling, already at 680 million tons annually, must scale further to utilize growing scrap stocks, while chemical sector circularity requires closing \"societal carbon loops\" via polymer recycling and bio-based feedstocks[3][6][35]. Industrial symbiosis amplifies savings; alumina refineries could supply residue for cement production, while steel slag might replace limestone in CO₂ mineralization processes[3][29].  \n\n### Electrification and Renewable Integration  \n\nElectrification displaces fossil-fired processes where technically feasible, particularly for under-1,000°C heat applications. Mining exemplifies this potential: switching diesel haul trucks to battery-electric models improves drivetrain efficiency from 30% to 90% and cuts ventilation needs by 30%, reducing site emissions 50–70%[33][36][38]. Pilbara's all-electric mine (operational since 2019) demonstrates full electrification viability, though power demand doubles, necessitating 2,000 GW of new renewable capacity globally for mining decarbonization[15][33][38]. For higher temperatures, resistive or induction heating powered by renewables offers pathways, but costs remain prohibitive for steel reheating (~$200/ton premium)[7][17]. Grid integration challenges include managing intermittent supply; Australian industrial hubs like Kwinana are modeling optimized energy flows using Model-Based Systems Engineering to balance electrolyzers, storage, and flexible loads[1][29].  \n\n### Hydrogen and Alternative Fuels Deployment  \n\nGreen hydrogen—produced via renewable-powered electrolysis—holds particular promise for steelmaking through hydrogen-based direct reduced iron (H₂-DRI), which emits water vapor instead of CO₂ and could capture 40% of the global steel market by 2050[8][17][37]. However, hydrogen faces barriers in cement and chemicals due to higher costs and integration complexity[7][20][35]. For example, ammonia production via electrolytic hydrogen increases capital intensity fourfold compared to steam methane reforming[35]. Biomass and biofuels serve as transitional alternatives; cement kilns can substitute 30–50% coal with agricultural residues, though sustainable feedstock limits exist[2][21]. Synthetic fuels (e-fuels) derived from green hydrogen and captured CO₂ may decarbonize high-temperature processes without equipment retrofits, but pilot projects remain nascent[7][14].  \n\n### Carbon Capture, Utilization, and Storage (CCUS)  \n\nCCUS is indispensable for cement (addressing process emissions) and abates 50% of heavy industry emissions in 2050 scenarios[5][7][14]. Post-combustion capture at cement plants could sequester 90% of emissions, with captured CO₂ utilized in concrete curing or algal biofuels[3][22]. However, costs vary geographically: plants within 200 km of storage sites incur $60–80/ton capture costs, rising to $160/ton beyond 750 km due to transport[20][22]. Current global CCUS capacity must scale 14-fold to meet 2050 targets, requiring $200–$250 billion investment for steel and cement alone[15][20]. Utilization pathways like CO₂-to-methanol offer revenue streams but face scalability challenges; only CarbonCure's mineralized CO₂ in concrete (2–5% emissions reduction) approaches commercialization[15][21].  \n\n### Innovative Production Processes and Materials  \n\nBreakthrough production processes could disrupt emission-intensive conventional methods. Hydrogen-based steelmaking (H₂-DRI) is scaling rapidly, with projects like HYBRIT in Sweden targeting commercial operation by 2026[17]. For cement, alternatives include Brimstone's carbon-negative process using calcium silicate instead of limestone, avoiding process emissions entirely, and electric recycled cement inspired by steel recycling chemistry[10][18]. Chemical sector innovations encompass biomass-based ethylene crackers and methanol synthesis from green hydrogen[32][35]. Novel materials also contribute: graphene-reinforced concrete could lower cement content 30%, while advanced alloys extend steel lifespan in construction[2][6]. However, 60% of required technologies remain at prototype stage, necessitating $1.4 trillion in R&D and deployment capital by 2050[5][15][16].  \n\n## Sector-Specific Decarbonization Analysis  \n\nIndustrial decarbonization strategies must address sector-specific constraints: steel requires hydrogen or CCUS retrofits; cement needs CCUS due to process chemistry; chemicals depend on green feedstocks; and mining favors electrification. Steel decarbonization leverages hydrogen-based DRI or CCUS-equipped blast furnaces, with regional variations; the G7 prioritizes hydrogen routes, while China favors CCUS retrofits[8][17]. Cement pathways hinge on clinker substitution (30–50% reductions) and CCUS deployment, though costs risk doubling cement prices to $160–240/ton[20][22][23]. Chemical decarbonization for ammonia and methanol focuses on renewable hydrogen, necessitating $440 billion–$1.1 trillion in electrolyzer investments[32][35]. Mining electrification offers the most mature route, with battery-electric equipment already reducing emissions 50–70% at operational mines[33][36][38].  \n\n### Iron and Steel Industry Pathways  \n\nThe iron and steel sector emits 3.4 gigatons of CO₂ annually (7% of global emissions), requiring $1.4 trillion investment to achieve net-zero by 2050[15]. Near-term priorities include energy efficiency (top-gas recovery turbines saving 20–30% energy) and material efficiency (lightweight design, scrap-based production)[17][37]. By 2030, electric arc furnaces (EAF) fed by recycled scrap could produce 30% of global steel, cutting emissions 45–60% compared to blast furnaces[15][17]. Long-term, hydrogen-based DRI offers zero-emission primary steel, with projects like Sweden's H2 Green Steel pioneering 5 million-ton plants by 2030[17]. Cost remains a barrier: green steel carries a $100–200/ton premium, potentially mitigated by carbon contracts for difference guaranteeing €52–100/ton CO₂[17][27]. The G7 leads deployment, targeting 20% hydrogen-based production by 2030—twice the global average—supported by infrastructure for low-emission hydrogen[5][8][19].  \n\n### Cement and Concrete Decarbonization  \n\nCement production emits 8% of global CO₂, with 60% from limestone calcination (CaCO₃ → CaO + CO₂)[18][21][23]. Decarbonization leverages three pillars: clinker substitution (30–50% reductions using fly ash or slag), alternative fuels (bioenergy covering 40% thermal needs), and CCUS (essential for residual emissions)[7][20][22]. Innovative processes include Brimstone's carbon-negative Ordinary Portland Cement and Solidia's reduced-temperature chemistry, both nearing commercialization[10][22]. However, CCUS dominates net-zero pathways; the IEA projects 12% of G7 cement production will integrate CCUS by 2030, rising to 65% by 2050[8][20]. Economic challenges include abatement costs of $160/ton CO₂ for CCUS and potential cement price increases to $160–240/ton, risking affordability without policy support[20][22][23]. Public procurement mandates for low-carbon concrete could create markets, while CBAM addresses carbon leakage[18][28].  \n\n### Chemical Sector Transformation  \n\nChemicals—notably ammonia, methanol, ethylene—emit 1.4 gigatons annually, with 75% from fossil feedstocks[32][35]. Ammonia decarbonization centers on renewable hydrogen via electrolysis, increasing capital costs fourfold versus steam methane reforming but eliminating 90% of emissions[35]. Methanol pathways include biomass gasification or e-methanol from green hydrogen and captured CO₂[32]. For olefins (ethylene/propylene), electrified steam crackers and bioethanol-to-ethylene routes could abate 70% of emissions at $900 billion–$1.5 trillion investment[32]. Sector-wide, the EU requires €1 trillion for net-zero transformation, including €400–600 billion for eight major chemicals, with operating costs rising 25–40%[35]. Demand-side policies like product standards rewarding recycled content (e.g., 50% recycled polymers) are essential to offset production costs[26][32][35].  \n\n### Mining Industry Electrification  \n\nMining contributes 4–7% of global emissions, predominantly from diesel mobile equipment (40–50%) and electricity consumption (30–40%)[33][36]. Decarbonization prioritizes electrification: battery-electric haul trucks improve drivetrain efficiency from 30% to 90%, reducing energy use 60–70% per ton mined[33][38]. Full electrification—exemplified by Boliden's Kevitsa mine—could eliminate 80% of scope 1 emissions and halve ventilation needs underground[33][36][38]. Supporting infrastructure requires doubling on-site renewable capacity and grid connectivity; Chilean copper mines are piloting solar-battery systems to power 300-ton electric trucks[33][36]. Alternative fuels like hydrogen may address residual diesel needs, but proton-exchange membrane fuel cells remain costly (~$1,500/kW). The Electric Mine Consortium—uniting 15 mining companies—targets zero-emission operations by 2040 through shared R&D on charging systems and energy management[38].  \n\n## Policy Frameworks and Governance Mechanisms  \n\nEffective decarbonization demands policy packages combining \"push\" measures (subsidies, standards) with \"pull\" mechanisms (procurement, carbon pricing). Carbon pricing alone proves insufficient; €81/ton CO₂ in Europe drives only 34% cement emissions reduction, requiring €155/ton for near-full abatement[18][23]. Carbon contracts for difference de-risk early projects by guaranteeing strike prices, as Germany's H2Global program does for green steel[17][27]. International alignment is critical: the Breakthrough Agenda coordinates 25 actions across power, hydrogen, and steel sectors, harmonizing definitions like \"near-zero emission steel\" to accelerate investment[4][12][19]. Border measures like CBAM prevent carbon leakage but must be paired with domestic decarbonization funding to maintain competitiveness[19][28][39]. National strategies vary; Australia funds industrial hub modeling via CSIRO, while the U.S. Inflation Reduction Act provides tax credits covering 30% of CCUS costs[1][24][29].  \n\n### National and Regional Policy Instruments  \n\nNational policies must create \"level playing fields\" for low-carbon materials through investment stimuli and regulatory certainty. The U.S. employs production tax credits ($85/ton for green hydrogen) and DOE grants funding 50% of first-of-a-kind projects, catalyzing 90 net-zero industrial projects[24][32]. The EU combines carbon pricing (€80–100/ton ETS) with CBAM to shield industries, though free allowance phaseouts risk competitiveness without scaling alternatives[18][28]. China prioritizes CCUS retrofits for steel and cement, leveraging state-owned enterprise investments, while Australia's HILT CRC develops tailored energy mix models for Pilbara and Spencer Gulf hubs[1][5][29]. Common challenges include green premium compensation; carbon contracts for difference—guaranteeing $100–150/ton CO₂ abatement—could bridge this gap for hydrogen steel[17][27]. Material efficiency policies are underutilized; ecodesign standards for buildings (steel intensity) or packaging (plastic recyclability) could reduce primary demand 15%[9][26].  \n\n### International Cooperation Frameworks  \n\nGlobal alignment prevents fragmentation and scales technology cost reductions through shared learning. The G7 leads through coordinated definitions: \"near-zero emissions\" cement must emit <0.1 ton CO₂/ton, with 27% emissions cuts by 2030 versus 18% elsewhere[5][19][39]. Mission Possible Partnership unites 200+ companies in sectoral alliances (e.g., Net-Zero Steel Initiative), providing transition roadmaps validated by producers like ArcelorMittal[17][24]. UNIDO promotes policy packages combining supply-side (renewable energy access) with demand-side (material efficiency standards), particularly for developing economies[26]. Financial institutions enable risk-sharing; the GFANZ network mobilizes $130 trillion toward breakthrough projects, while the Clean Energy Ministerial funds CCUS infrastructure corridors[12][16]. Critically, technology transfer mechanisms—like IP sharing for hydrogen DRI—must balance commercial interests with global equity to avoid a two-track transition[5][16][19].  \n\n### Financing Mechanisms and Investment Catalyzation  \n\nHeavy industry decarbonization requires $4–6 trillion cumulative investment by 2050, necessitating blended finance models[5][15][32]. Public funding anchors high-risk projects: the U.S. DOE allocates $6.3 billion for industrial demonstrations, while the EU Innovation Fund offers €40 billion for CCUS hubs[16][24][39]. Private capital follows via offtake agreements; Volvo and Mercedes secured 30–50% green steel premiums through 2030 purchase commitments[17]. Specialized instruments include carbon credits for residual emissions ($250 billion needed for steel) and sustainability-linked loans tying interest rates to emission targets[15][26]. Mining exemplifies collaboration: the Electric Mine Consortium pools resources for charging infrastructure R&D, lowering per-company costs 40%[33][38]. Emerging economies face funding gaps; multilateral development banks must expand concessional finance, with IDA providing $2 billion for Indian steel CCUS[5][16][26].  \n\n## Economic Feasibility and Investment Analysis  \n\nHeavy industry decarbonization is technically feasible by 2050 at under 0.5% of global GDP cost, but requires strategic investment sequencing and policy support to manage green premiums[2][9][37]. Near-term actions yield low-cost wins: energy efficiency and material circularity abate 25–30% of emissions at negative to $50/ton CO₂ costs[5][17][22]. By 2030, low-regret technologies—scrap-based steel, clinker substitution—could achieve 10–33% sectoral reductions with minimal consumer impact[17][23]. Post-2030, harder abatement (hydrogen, CCUS) demands $1.1–1.4 trillion annually, with costs concentrated in infrastructure: $200 billion for CO₂ pipelines, $1.1 trillion for renewable hydrogen systems[15][20][32]. Green premiums vary widely: ammonia costs double with green hydrogen, cement rises 40–120%, while recycled aluminum carries just 5–10% premiums[20][25][35]. Carbon pricing above $100/ton closes cost gaps for 75% of solutions, but targeted support prevents regional disparities[18][23][27].  \n\n### Abatement Cost Curves and Green Premiums  \n\nMarginal abatement costs span from -$50 to $350/ton CO₂ across technologies and sectors[20][30]. Steel decarbonization averages $115/ton via hydrogen DRI but drops to $25/ton with $20/MWh renewables, while material efficiency cuts costs to $7/ton[13][17]. Cement CCUS costs $160/ton, but clinker substitution saves $20–30/ton[20][22][23]. Green premiums—price differences between conventional and low-carbon products—range from 10% for recycled-content goods to 100% for early green steel[17][20][35]. Policy interventions shrink these: carbon contracts for difference cap premiums at €100/ton steel, while the EU CBAM equalizes import costs[17][27][28]. Long-term, learning curves and renewable cost declines could eliminate premiums; hydrogen electrolysis may fall below $1.50/kg by 2040, making green steel cost-competitive[2][17][37].  \n\n### Capital Requirements and Financing Structures  \n\nAchieving net-zero across heavy industry demands cumulative investments of $4–6 trillion by 2050, dominated by infrastructure[5][15][32]. Steel requires $1.4 trillion globally ($250 billion for CCUS), cement $1.1 trillion (60% for CCUS), and chemicals $1.1–$1.5 trillion[15][20][32]. Mining electrification needs $500 billion for equipment and grid upgrades[33][36]. Funding structures include project finance (80% debt for CCUS hubs), corporate PPAs for renewables, and securitization of carbon credits[15][20]. Risk mitigation is critical: the U.S. DOE Loan Guarantees cover 80% of first-of-a-kind project debt, while Australia's CEFC provides concessional loans at 1–3% interest[24][29]. Blended finance taps institutional capital; Norway's Norfund co-invests with private equity in African green ammonia plants, accepting subcommercial returns for development impact[16][32][39].  \n\n### Economic Impacts and Competitiveness Considerations  \n\nDecarbonization reshapes industrial geography based on renewable access, storage proximity, and policy support. Cement plants within 200 km of CO₂ storage gain 50% cost advantages, potentially shifting production from inland to coastal sites[20]. Aluminum smelters cluster near hydropower (Canada, Norway), while green steel favors solar/wind-rich regions (Australia, Chile)[17][25]. Trade policies prevent offshoring; the EU CBAM imposes carbon costs on imports, shielding domestic producers during transition[19][28]. Employment effects are mixed: 200,000 jobs may be lost in fossil-dependent industries, but 400,000 created in hydrogen, CCUS, and recycling[17][26]. Developing economies face acute challenges; India's steel decarbonization could raise costs 30%, necessitating Just Transition financing to avoid lock-in[5][16][26]. Conversely, resource-rich nations (Chile, Morocco) could capture $300 billion/year in green hydrogen exports[8][19][32].  \n\n## Regional Case Studies and Implementation Progress  \n\n### G7 Leadership and Project Deployment  \n\nG7 members—producing 17% of global steel, 8% of cement, and 28% of chemicals—prioritize near-zero emission production as a strategic imperative[5][19][39]. The U.S. leads with 90 commercial-scale projects, including Cleveland-Cliffs' hydrogen DRI plant and Heidelberg Materials' CCUS-equipped cement kiln[24]. Germany pioneers carbon contracts for difference, guaranteeing €100/ton CO₂ for thyssenkrupp's hydrogen steel, while Japan focuses on CCUS-equipped blast furnaces[17][27]. By 2030, the G7 targets 10–20% market share for near-zero materials, doubling the global average, supported by infrastructure like Germany's H2ercules hydrogen network[5][19][39]. Challenges persist: free allowance phaseouts under ETS could raise production costs 20%, requiring CBAM to maintain competitiveness[19][28].  \n\n### Australian Industrial Hubs  \n\nAustralia leverages renewable abundance to model optimized decarbonization pathways for Pilbara, Kwinana, and Upper Spencer Gulf hubs[1][29]. CSIRO's Model-Based Systems Engineering (MBSE) approach simulates energy flows—electricity, hydrogen, heat—across interconnected industries, identifying cost-optimal mixes[1][29]. Pilbara's iron ore mines could integrate 10 GW solar to power onsite electrolysis, supplying hydrogen for DRI plants and ammonia exports[1][33]. Kwinana's alumina refineries may use mechanical vapor recompression (cutting energy 60%) and supply residue to cement plants[1][3]. The HILT CRC project quantifies energy costs at five-year increments to 2050, informing government infrastructure investments and industry transition planning[1][29]. Regional advantages include low-cost renewables (<$20/MWh) and existing export infrastructure, potentially enabling $50/ton green iron competitive with conventional imports[1][25][29].  \n\n### European Union Policy Integration  \n\nThe EU combines regulatory drivers (ETS, CBAM) with innovation funding to accelerate heavy industry transition[18][27][28]. ETS carbon prices (€80–100/ton) drive near-term efficiency, while the Innovation Fund's €40 billion supports first-commercial projects like HYBRIT hydrogen steel[17][18]. CBAM, applied to cement and steel imports, levels carbon costs while free allowances phase out by 2034[28]. Circular economy policies—Ecodesign for durability and recycled content quotas—could reduce primary steel demand 15% and cement 10%[17][26]. National nuances emerge: Sweden's HYBRIT leverages hydropower for hydrogen, while France targets nuclear-powered electrolysis[17][35]. However, fragmentation risks persist; unified definitions for \"low-carbon cement\" (embedded CO₂ <0.1 ton/ton) and cross-border CO₂ networks require further harmonization[19][20][26].  \n\n## Conclusion: Synthesis and Forward-Looking Recommendations  \n\nHeavy industry decarbonization is technically feasible by 2050 but demands unprecedented coordination across technology, policy, and finance domains. Core pathways include hydrogen-based steelmaking, CCUS-equipped cement plants, chemical feedstocks from electrolysis, and mining electrification—collectively reducing emissions 90–95% from current levels[5][8][17][20]. Economic viability hinges on managing $1.1–1.4 trillion annual investments and sector-specific green premiums through carbon contracts for difference, public procurement, and infrastructure co-funding[17][20][27]. Policy must prioritize five areas: harmonizing \"near-zero\" definitions internationally to prevent fragmentation, scaling carbon management infrastructure via public-private partnerships, embedding circularity in product standards to reduce primary demand, securing concessional finance for emerging economies, and establishing just transition mechanisms for workforce reskilling[5][19][26][39]. Immediate actions—deploying 200+ commercial-scale hydrogen or CCUS projects by 2030—could halve emissions growth trajectories while driving cost reductions through learning curves[8][16][24]. Without accelerated efforts, hard-to-abate sectors risk consuming 35% of the remaining carbon budget by 2050, making industry decarbonization not just an environmental imperative but an economic necessity for sustainable development[2][9][37]."
