Manufacturing is one of North America’s largest sources of greenhouse gas emissions, responsible for roughly one-third of total industrial output. As a result global pressure to cut carbon emissions is mounting, and manufacturers and producers of goods face a dual challenge: maintaining or increasing operational efficiency while meeting new sustainability targets.

Decarbonization isn’t just a buzzword, it’s a practical pathway to lower costs, increase operation efficiency and resiliency, secure government incentives, and gain a competitive edge in an increasingly low-carbon marketplace.  

We spoke to our sustainability experts to help break down what decarbonization means for manufacturers, why it matters, and how you can start building an industrial decarbonization roadmap that aligns with your business goals and regulatory requirements. 

What is Decarbonization?

Decarbonization in manufacturing refers to the reduction of greenhouse gas (GHG) emissions from industrial processes, energy use, fuels, operations, and materials. This includes both operational and embodied carbon. It’s not about overhauling your facility overnight, but rather, about taking practical, data-driven steps to lower your carbon footprint while maintaining productivity, controlling costs and strengthening competitiveness. 

Understanding Operational vs. Embodied Carbon in the Manufacturing Industry 

Before building a decarbonization plan, it’s essential to understand where emissions come from and how they’re measured. Emissions are grouped into Scope 1, 2, and 3 emissions which are often referred to as operational or embodied carbon.

Scopes 1 &2 and Operational Carbon Emissions 

Operational carbon refers to the emissions that are generated from day-to-day running of your facility or business activities, including the energy you consume, the fuel you burn, and the electricity you draw from the grid. This typically includes Scope I and Scope II emissions. These are the emissions you can influence through energy efficiency, fuel switching, and clean energy sourcing. Scope I and II emissions include: 

• Scope1 : Emissions generated on-site from fuel combustion or chemical processes, or refrigerants released that are from owned assets. Examples: Burning natural gas in a boiler or furnace; running diesel-powered equipment; using propane for process heat. 

• Scope 2: Emissions off-site that occur from generation of purchased electricity, steam, heating, or cooling used by your plant. Examples: Electricity used to power production lines, lighting, or HVAC systems.  

Operational carbon is the most visible and measurable part of your emissions profile, and usually the first area to target for reduction. 

Scope 3 Emissions and Embodied Carbon 

Unlike operational carbon, embodied carbon is harder to control because it’s tied to your supply chain. It’s becoming increasingly important and more common for customers and regulators to demand transparency. 

• Scope 3: Emissions that occur outside your direct operations, either upstream or downstream in the supply chain. Examples: the carbon footprint of purchased steel, concrete, or machinery used in your operations, transportation of materials and finished goods, waste disposal or recycling, employee computing, operation of leased assets, waste generated and the lifecycle emissions of your products once they’re in use. 
• Embodied Carbon: Embodied carbon refers to the emissions generated from the use of materials, products, and services your plant purchases or uses, as well as what happens to your products after they leave your facility during the product life cycle. 

To quantify embodied carbon, many manufacturers now rely on and provide an Environmental Product Declaration (EPDs) which quantifies and reports the disclose emissions generated with a product’s manufacturing and lifecycle. EPDs are becoming mandatory for many public and private projects across the U.S. and Canada, meaning plants that can provide this data gain a competitive edge. 

Why Decarbonization in Manufacturing Matters in North America 

Decarbonization is no longer a distant goal, it’s a business-critical strategy. Rising energy costs, tightening regulations, and growing customer demand for low-carbon products are reshaping the competitive landscape.  

1. Regulatory, Customer, and Investor Pressure

Government policies in the U.S., Canada, and globally increasingly focus on industrial GHG emissions. New incentives and mandates are pushing manufacturers toward cleaner operations. At the same time, customers and investors are demanding transparency through EPDs and sustainability reporting. Falling behind means losing contracts and losing market access.

2. Cost Savings and Competitiveness

Improving energy efficiency remains the most cost-effective decarbonization lever. Reducing waste energy and optimizing energy systems not only reduces emissions but directly lowers operating costs. Plants that act early can reinvest those savings and strengthen their competitive edge having a compounding effect.

3. Risk Mitigation and Future-Proofing

As energy and emission pricing expands, older, fuel-intensive equipment is becoming a liability. An industrial decarbonization roadmap helps you plan upgrades strategically rather than reactively, minimizing risk.

4. Safety, Reliability, and Reputation

Often decarbonization measures overlap with reliability and planned maintenance improvements. Optimizing systems to waste less energy often makes them safer and more dependable with longer life spans. Plus, a proactive approach that supports sustainability objectives enhances your company’s reputation among customers, communities, and future employees.

In short, manufacturers that act now can unlock significant business benefits like:  

• Reduce energy/utility bills through energy efficiency and decreasing emissions 
• Win new customers by offering low-carbon alternatives backed by EPDs 
• Access government incentives, such as SaveOneEnergy, Enbridge programs, and federal programs and tax incentives reducing capital costs.  
• Avoid stranded assets by transitioning proactively 
• A stronger market position as buyers increasingly favour and, in a number of cases, require suppliers to provide Environmental Product Declarations (EPDs) 

Who Is Impacted?

Decarbonization touches nearly every corner of the manufacturing ecosystem. Energy-intensive industries such as automotive, steel, cement, aerospace, and mining equipment manufacturing are sectors that are particularly impacted because they generate substantial scope 1 and 2 emissions through on-site fuel use and electricity consumption.

1. The Manufacturing Sector at Large

Across the globe, manufacturers are under mounting pressure to modernize operations and align with net-zero goals. Increasing supply chains are being impacted by a changing climate, increasing risks and costs. 

2. High-Emission Sub-Sectors Under Pressure

Some sectors are being hit first and hardest:

• Steel and metals: Facing global competition from electric arc furnaces and hydrogen-ready technologies.
• Cement and concrete: Embodied carbon is becoming a deciding factor in procurement for infrastructure projects.
• Automotive and aerospace: OEMs now often require low-carbon parts and verified emissions data from suppliers.
• Heavy equipment and machinery: Scope III supply-chain emissions are becoming part of compliance and contract requirements.

These sectors aren’t just facing regulatory change, they’re facing a market reset. The winners will be those who prove they can manufacture efficiently, responsibly, and transparently. In other words: decarbonization and increasing resiliency in operations is now an operational advantage, not a compliance burden. 

How to Reduce Carbon Emissions in Manufacturing 

Decarbonizing your facility doesn’t happen overnight. It requires a structured, planned, and practical approach. Here’s how manufacturing facilities can start: 

Step 1: Define Your Goals 

Start your industrial decarbonization roadmap with clear, defined goals. Begin by setting a clear vision for your decarbonization journey. 

• Define what decarbonization means for your facility (e.g. 30% emissions reduction by 2030) 

• Link your goals to tangible business drivers: high energy bills, customer expectations, or equipment nearing replacement 

• Figure out what’s driving this? Internal goals and ambitions, regulatory compliance, customer demand for low-carbon products, or cost savings 

• Decide on the boundaries. Will you include only operational emissions (Scope 1 & 2) or tackle Scope 3 emissions? 

• Get leadership and finance on board early to increase buy-in 

Establishing measurable goals aligned with industry standards ensures your roadmap is credible and actionable. Do this by putting concrete numbers and timelines into the goals, for example, you could aim to achieve net-zero by 2050 or 30% reduction by 2030.  

Anchor targets in science-based frameworks where available. Setting science-based targets ensures credibility and positions your company as a leader. For example, automotive suppliers in Ontario and Michigan are increasingly asked for emissions associated with products by OEMs having a clear emissions reduction plan can make you a preferred partner. 

Step 2: Benchmark Your Current Footprint 

You can’t manage what you don’t measure. That is why benchmarking is a critical step in how to reduce carbon emissions in manufacturing effectively. 

• Conduct an energy and emissions audit and inventory to map your biggest sources of GHGs 

• Identify inefficiencies: wasted heat, overused systems, old motors, and leaks 

• Collect data from utilities, operations, and maintenance logs to build a reliable starting point 

This step gives you a baseline and highlights where your investments will have the most impact. Benchmarking also helps you compare against industry standards. For example, steel manufacturers in Ontario can leverage provincial benchmarking programs tied to incentives. 

Manufacturers who understand their emissions data and act early will position their operations as industry leaders. Those who wait risk getting locked into outdated infrastructure that’s costly to retrofit later. 

Step 3: Develop the Implementation Roadmap

Once you know where you stand, build scenarios that align with your capital planning and risk tolerance: 

• Aggressive Path: Rapid electrification and renewable integration 

• Balanced Path: Gradual upgrades aligned with asset replacement cycles 

• Optimized Path: Measures that maximize $ invested per GHG reduced 

You can also prioritize quick wins and long-term moves such as: 

• Quick wins: Optimize controls, improve insulation, fix compressed air leaks, tune boilers, and implement waste heat recovery strategies 

• Strategic moves: Electrify fossil-fuel equipment, switch to renewable power, and plan for clean fuels or carbon capture 

• Start with the biggest impact: Rank projects based on “dollars per tonne of carbon reduced” to focus on the biggest impact per dollar spent 

• Prioritize: Break actions into near-term (0–2 years), medium-term (3–5 years), and long-term (5–10+ years) horizons 

For many manufacturers, the biggest opportunities and risks are found inside the plant gates. Equipment upgrades, maintenance decisions, and daily operational choices directly influence a facility’s carbon profile. Focusing on these high-impact strategies form the core of how to reduce carbon emissions in manufacturing while maintaining productivity and controlling costs:

• Energy Efficiency: Insulation, energy use optimization, waste heat recovery 

• Electrification: Replace gas-fired boilers with electric heat pumps 

• Clean Fuels: For hard-to-electrify processes, explore biofuels or hydrogen 

• Materials Efficiency: Design for less material use and recycled content 

Step 4: Track Progress and Scale

Continuous monitoring keeps your strategy on track and positions your operations for future incentives, verifies savings, and reductions.

• Monitor results annually and compare against your baseline
• Use data dashboards or sustainability reports to communicate progress internally and externally
• Expand successful measures across facilities and suppliers
• Explore grants, incentives, and rebates available in your region
• Treat each project as you would any other capital investment. Plan for reliability, safety, and production continuity

Update your roadmap annually or every few years as new technology and regulations evolve. Consider supply-chain (Scope III) emissions once your own operations are under control.

Decarbonizing Manufacturing Facilities: What Could Go Wrong?

After many sustainability and decarbonization projects in manufacturing facilities across North America, we’ve learned a lot. Here are some common pain points and pitfalls that we see manufacturers make (and how to manage them): 

• Production disruption fears: Schedule upgrades during planned maintenance windows or during shut down periods. 

• Limited data: Begin with what you have and work to fill in gaps as you go that can be filled over time. 

• Aging equipment: Integrate decarbonization into your normal asset replacement cycle considering an upgrade at the time of replacement as opposed to a like for like replacement 

• Skills gap: Providing training on new systems  help teams understand and integrate with new technologies to ensure they operate properly to provide benefits and energy savings to reduce emissions. 

Final Thoughts

Decarbonization is no longer a niche sustainability initiative, it’s a defining factor in the future competitiveness of manufacturing. For plant managers, the question isn’t if you should act, but how quickly can you integrate these changes without disrupting operations? The reality is that regulatory pressure, customer expectations, and investor scrutiny are looking for low carbon and resiliency manufacturing practices. Companies that fail to adapt risk higher costs, stranded assets, and diminished market share as low-carbon products become the norm.  

By taking a structured, engineering-informed approach, manufacturing plants can cut costs, future-proof operations, and strengthen their market position while doing the right thing for the environment and global emissions. 

Decarbonization isn’t just about reducing carbon, it’s about building a smarter, more profitable, and future-ready manufacturing business.
