NET Zero means reducing greenhouse gas emissions as much as possible and compensating or neutralizing only residual emissions that cannot be eliminated. For the industry, achieving this goal requires progressively transforming the way energy is consumed and production processes are developed.
What you should know about Net Zero in the industry
-
- The NET Zero concept requires exhausting all direct reduction routes in the plant before going to carbon neutralization or compensation mechanisms.
- It is only allowed to compensate for those residual emissions whose elimination is not technically feasible with the technologies currently available.
- It should not be confused with “zero emissions” (elimination of 100% emissions without compensation) or the basic “climatic neutrality” supported by carbon credits.
- Reaching the NET Zero requires integrating climate commitment within the exploitation model, combining energy efficiency, fuel substitution and digitization.
- Industrial decarbonisation is the technical and progressive path; NET Zero is the final long-term goal or state of equilibrium.
What does Net Zero mean?
In the industrial field, Net Zero refers to the equilibrium state in which the productive activities of a plant or corporation do not generate a net impact on global warming. This implies that the total sum of its released emissions equals zero after having applied drastic reductions in all processes and implemented absorption solutions for the remainder that is not eliminable.
Reduce emissions before compensating
The fundamental pillar that defines the Net Zero standard is the Mitigation hierarchy. A company cannot declare Net Zero only by buying carbon credits in the markets to offset its usual emissions. international regulations and initiatives (such as Science Based Targets – SBTI) are required to effectively reduce between 90% and 95% of direct and indirect emissions from the value chain before neutralizing the remaining balance.
What are residual emissions
Residual emissions are those greenhouse gases that remain after having applied all measures of efficiency, electrification and substitution of possible fuels. They arise in complex industrial chemical processes (such as calcination in the manufacture of cement) or in very high temperature thermal operations where there are still no commercially mature renewable alternatives.
The balance between emissions and elimination or neutralization
The result pursued in the final phase of the Net Zero path is achieved when each ton of residual CO2 that the plant expels into the atmosphere is captured and stored permanently by technological solutions (such as CCU systems) or absorption based on nature.
Net Zero Balance = Generated Emissions – Emissions Eliminated/Caught = 0
Net Zero, zero emissions and climate neutrality: are they the same?
It is very common to use these terms indistinctly, but in the B2B technical and regulatory environment they respond to concepts with very different operational and legal implications:
| Concept | What does it imply operationally? | Direct reduction requirement |
| Zero emissions (Zero Emissions) | Absence or absolute elimination of 100% of the emissions at the source. It does not generate any type of gas. | 100% (does not allow compensation) |
| NET Zero (Net Zero Emissions) | Maximum drastic reduction of 90-95% of emissions + permanent neutralization of the residual balance only. | Very high (90-95%) |
| Climate neutrality | Balance between emissions and absorption, allowing a wider use of external compensation credits. | Variable (subject to voluntary standards) |
| Decarbonization | The process of technical and progressive transformation to reduce emissions from the plant. | Ongoing (it is the target tool) |
What does Net Zero mean for an industrial company?
Adopting a NET Zero commitment transversally transforms the operation and decision-making of a manufacturing company.
Check where emissions are generated
Reaching this objective requires thorough auditing of all corners of the plant: from gas combustion in steam boilers to electricity consumption or logistics of inputs. If you need to structure the data collection of your installation, we invite you to consult our guide on How to calculate and reduce the carbon footprint in the industry.
Transform energy consumption
It involves migrating the thermal generation model in a planned way. This is achieved by substituting traditional fossil boilers with mature technologies such as Industrial biomass, integrating heat pumps for medium temperatures or evaluating alternatives within the range of Technologies for industrial decarbonization.
Reduce emissions associated with the production process
It requires redesigning the operating guidelines, revaluing the by-products of the manufacturing chain itself and implementing circular economy solutions to reduce the impact of inputs and raw materials.
Integrate the objective in the business strategy
NET Zero is no longer an isolated responsibility of the Department of the Environment to become a KPI of the organization’s board of directors. conditions the allocation of the capital budget (capex), the selection of suppliers and the development of new products.
Why is the industry betting on Net Zero objectives?
Moving towards a zero net emissions model is not just a response to the climate crisis, but also a financial and commercial protection decision.
-
- Competitiveness and transformation of the market: Large multinationals are filtering their suppliers. Having a transparent roadmap to NET Zero is a requirement not to be left out of international tenders.
-
- Reduction of exposure to fossil fuels: Replacing hydrocarbons with local renewable vectors protects the factory from the stock market volatility of natural gas and oil.
-
- REGULATORY AND SUSTAINABILITY REQUIREMENTS: The Greenwashing Denial Directive and the EU CSRD framework sanction ambiguous messages, demanding transition plans backed with verifiable data.
-
- Customer and supply chain requirements: Scope 1 and 2 emissions from a manufacturing industry represent reach 3 of its customers. Reducing them helps keep key contracts.
-
- Access to new investment and financing opportunities: Capital funds and corporate banking apply strict ESG criteria, offering better credit conditions to companies with validated climate targets.
What emissions should a Net Zero strategy take into account?
In order for a neutrality plan to be credible and can be approved, it must address the three scopes marked in the calculation methodology of the GHG Protocol:
-
- Direct Emissions (Scope 1): released in situ For the combustion of fossil fuels in boilers, ovens, dryers or vehicles owned by the company.
-
- Indirect emissions by energy (Scope 2): generated during the production of electricity, steam or refrigeration that the plant buys from the commercial network.
-
- Value chain emissions (Scope 3): generated in the extraction of the raw materials purchased, the external logistics transport, the management of waste or the final use of the manufactured products.
The road to Net Zero: the main levers for the industry
The transition to net zero emissions requires combining different technological solutions depending on the thermal and productive profile of the plant:
| Technological lever | Main operating objective |
| Energy efficiency | Reduce energy base consumption through insulation, recovery and energy optimization. |
| Electrification | Replace processes based on low and medium temperature fossil fuels with clean electricity. |
| Renewable generation | Eliminate Scope 2 emissions through photovoltaic self-consumption or renewable PPA. |
| Bioenergy | Replace natural gas in boilers with sustainable biomass to generate steam and continuous heat (Scope 1). |
| Process optimization | Digitize the plant using sensors and AI to eliminate waste and thermal waste. |
| Innovation and CCU | Capture and neutralize CO2 in processes hard-to-abate very high temperature or chemical reaction. |
Energy efficiency
It is the starting point. Implementing economizers, recovering condensates and integrating frequency drives into motors allows you to reduce the total consumption of the plant before sizing the new renewable equipment.
Process electrification
Ideal for low temperature applications, where the installation of high-efficiency heat pumps replaces gas burners without generating direct emissions.
Renewable generation
Hire electric PPA (Power Purchase Agreements) Renewable or install solar panels on the deck of the ships neutralizes the indirect impact derived from the electricity consumption of the network.
Biomass and other bioenergy solutions
For thermointensive industries requiring uninterrupted supply of steam or process heat (24/7), the proximity industrial biomass is the most mature and competitive renewable alternative to eliminate direct scope 1 emissions.
Optimization of industrial processes
SCADA systems and management platforms under ISO 50001 allow real-time auditing of the consumption per ton of manufactured product, identifying any deviation.
Technologies for hard-to-remove emissions
In sectors such as the cementist, steel or chemical, the final phase of approaching the Net Zero will require the integration of vectors such as green hydrogen or carbon capture (CCUS).
How to Define a Realistic Net Zero Objective
Establishing a corporate goal requires a pragmatic approach based on the company’s technical and financial capacity:
-
- Know the starting point: Prepare an exhaustive inventory of direct and indirect emissions of the company.2.
- Identify the main sources of emission: Locate thermal or electrical processes that concentrate the highest percentage of emissions.
- Prioritize emission reduction: Design actions focused on efficiency and substitution of fuels before considering any neutralization option.
- Set temporary goals: Set short and long-term verifiable intermediate milestones
- Define indicators to measure progress: Monitor current metrics as TCO2e / unit produced.
- Review and update the strategy: Adapt the roadmap as the available technologies and the regulatory framework evolve.
How long does an industry need to reach Net Zero?
There is no single universal term to reach the Net Zero. The time horizon usually varies between 5 and 20 years, depending on the starting point of the factory, the intensity of its thermal consumption, the technical maturity of the alternatives available for its processes and the selected financing model.
The factors that condition the execution time are:
-
- Starting point: Boiler age and previous level of efficiency.
-
- Energy intensity: total volume of thermal MWh consumed.
-
- Easy sectors vs. Difficult implantation: A food factory can achieve zero net emissions in a few years by substituting its boilers for biomass, while a steel company will depend on the development of green hydrogen on a large scale.
-
- Investment capacity and financial model: Recourse to financing schemes without initial capital drastically accelerates the implementation of projects.
Main challenges to achieve Net Zero in the industry
Overcoming the barriers of transition requires a realistic diagnosis of operational obstacles:
-
- Difficult to electrify processes: The technical impossibility of replacing with electricity the requirements of massive steam or very high temperature heat.
-
- Investment and economic viability: the need to contribute capital (capex) to renew the thermal power plants of the plant.
-
- Availability and maturity of certain technologies: The lack of large-scale commercial development of some advanced solutions.
-
- Emissions measurement and monitoring: The complexity to obtain reliable data from scope 3 in global supply chains.
-
- Internal coordination: The need to align factory operations with the purchasing, sustainability and finance departments.
NET Zero and Industrial Decarbonization: How they relate
The Industrial decarbonisation It is the process of technical, operational and energy transformation through which a plant progressively reduces its carbon emissions. The NET ZERO It is the final objective or long-term equilibrium state that is achieved when said decarbonization process has reduced emissions to the maximum and the residual balance has been neutralized.
Understanding this semantic difference is key: decarbonization is the way (efficiency measures, bioenergy, electrification), while NET Zero is the certifiable goal. To delve into the concept of this transformation process, you can consult our article Pilar on What is Industrial Decarbonization.

Frequently Asked Questions about Net Zero
Does Net Zero mean eliminating all emissions?
Not necessarily. It means removing the maximum technically possible (usually 90-95%) and compensating or capturing the residual percentage that cannot be removed.
What is the difference between Net Zero and Climate Neutrality?
Climate neutrality can be achieved by purchasing carbon credits to compensate for current emissions without making major internal changes. The Net Zero requires drastically reducing emissions from the plant itself before going to any neutralization.
Can a company achieve Net Zero by compensating all its emissions?
No. International standards disqualify strategies based solely on the purchase of compensation credits without having applied previous direct reductions in the facility.
Which industrial sectors have the most difficulty reaching Net Zero?
the sectors hard-to-abate With inherent process emissions or very high temperatures, such as steel, cement production, lime and heavy chemicals.
How is the advance towards a Net Zero target measured?
Annually auditing the carbon footprint of each organization under the standard GHG Protocol and other international standards that compare the emission ratios per manufactured unit (t CO2e / unit) with respect to the base year.
