Three Practical Boundaries for Printing Plants Pursuing “Green Factory” Certification: GB/T 36132 Mandatory Indicators / Local List Management / Whether It Is Worth Applying

In June 2026, the owner of a packaging printing plant contacted us—not to discuss printing, but to seek guidance.

He said: “We want to apply for green factory certification. Help us identify what we need to prepare.”

We asked three questions: “Do you want to pursue a local list or national-standard evaluation? These are different paths. What is your annual revenue? What processes do you use—printing packaging materials or commercial print?”

The third question was actually the most important. Nearly every failed case we encountered involved preparing a commercial printing plant according to the requirements for a packaging material manufacturer.

The First Boundary: Mandatory Indicators and Bonus Indicators Under GB/T 36132

First, GB/T 36132, General Principles for Green Factory Evaluation, is an evaluation standard, not an entry threshold. It is an evaluation framework comprising six primary indicators: factory characteristics, infrastructure, management systems, energy and resource inputs, main products, and degree of greenness, each supported by numerous secondary and tertiary indicators.

For printing plants, the most practical distinction is as follows:

Mandatory indicators (failure to meet them means immediate disqualification):basic factory compliance, including compliant land-use designation, safe building structures, fire protection acceptance, environmental protection formalities, including environmental impact assessment and pollutant discharge permits, as well as energy metering equipment. There is no room for compromise on these requirements; missing any one of them prevents entry into the evaluation process.

Substantive indicators (high weighting and requiring genuine investment):energy and resource inputs, including energy consumption per unit of product, water consumption per unit of product, and consumption of raw and auxiliary materials. For printing plants, these figures directly correspond to paper, electricity, water, and solvent consumption. They cannot be produced by filling out forms; they must emerge from production management.

Bonus indicators (providing differentiation):extended provisions within the management system, green products under Green Factory Evaluation Plus, and the application of digital management systems.

The key assessment is: mandatory indicators concern whether requirements are met, substantive indicators concern quantities, and bonus indicators concern quality. The greatest waste of resources during preparation occurs when substantial time is spent on bonus indicators while energy and resource data has never been extracted from the production system.

Our first recommendation to the printing plant owner was: begin by clearly calculating the unit of energy consumption per unit of product.Some plants use energy consumption per CNY 10,000 of output, others use energy consumption per tonne of product, and others use output per square metre. Without a consistent calculation basis, the plant may be required to recalculate and convert its data during evaluation. This task usually requires more effort than expected.

The Second Boundary: Local Lists and National-Standard Evaluation Are Separate Paths

This is the point most people misunderstand.

In practice, the general path is: the local industry authority organizes applications and evaluations → inclusion in a provincial or national green factory list → list-based management.Within this system, “green factory” is first and foremost a list identity, with ongoing dynamic management and review required after inclusion.

GB/T 36132, meanwhile, serves as the evaluation basis. Local evaluators use it or a locally adapted version of it.

The relationship can therefore be summarized as: the national standard sets the benchmark, local authorities issue the designation, and list inclusion is the outcome.

This distinction has three practical implications for printing plants:

First, applications have fixed submission windows.Local authorities generally organize one application cycle each year, with limited quotas, and many prioritize enterprises above designated size thresholds and those considered representative of their industry. Applications cannot be submitted at will; eligibility depends on the conditions in that year’s official notice.This is frequently overlooked—a printing plant may spend six months preparing only to miss the application window, wasting all that effort.

Second, the preparation is driven by customers with a business need, rather than by evaluators.The real impetus is usually a customer’s supply-chain questionnaire: the customer requires completion of a green factory questionnaire or inclusion in its green supply-chain directory.This is the genuine commercial motivation.

Third, list status must be maintained after inclusion.Dynamic management requires the continuous provision of energy data and participation in inspections. Certification is not the end of the process.Many printing plants are enthusiastic during the application but later discontinue data reporting and are removed from the list at re-evaluation two years later.

Our own factory is not an applicant. We are a printing plant supplying packaging materials to customers. Therefore, our perspective on this issue is highly specific: which items in customer questionnaires require data from us, and in what form those data exist within our factory.

The Third Boundary: Whether It Is Worthwhile Depends on Two Questions, Not Three

The printing plant owner finally asked: “Is it worth spending the money?”

Our decision framework contains only two questions:

Question 1: Do any of your customers explicitly assess this?

If a customer questionnaire asks questions such as “Has the company been recognized as a green factory?” or “Has the company passed ISO 14001?”, and you already supply these customers, the cost can be incorporated into existing customer relationships and is worthwhile. If the rationale is only that it “may be useful someday,” do not proceed yet.

Question 2: What is the foundation of your production management?

This threshold is often overestimated. If a printing plant currently records energy consumption manually, tracks production data on paper forms, and cannot even calculate its own output accurately, the application workload is not simply “filling out a few forms.” Instead, it requires first establishing a basic energy and production metering system. This investment may take several months.

Conversely, if the plant already has ISO 14001, energy metering equipment, and monthly energy consumption records, applying simply means organizing existing systems into the format required by evaluators, resulting in a much lower workload.

There is also an opposite-side cost to consider: data must be genuine throughout the application period.Green factory evaluation includes on-site verification and examines actual operating data. If data are temporarily embellished for the application, problems will emerge at the following year’s re-evaluation.We encountered a plant that “adjusted” an abnormal monthly energy-consumption figure for its application. The discrepancy was identified during re-evaluation, creating an even greater problem.

If You Are Preparing to Apply, Follow This Sequence

Based on our experience with numerous printing plants, we recommend the following practical sequence:

Step 1: Confirm the eligibility conditions first.Review the application requirements in that year’s local notice, including enterprise size, eligible industries, whether ISO 14001 is already required—many jurisdictions make this a prerequisite—and the application deadline. This step costs nothing but can eliminate all ineffective investment that would otherwise follow.

Step 2: Establish your baseline.Calculate energy consumption, water consumption, and material consumption per unit of product, and compare these figures with advanced benchmarks in the same industry. If the gap is too large, do not rush to apply; improve management first—because during evaluation, having no improvement plan is more damaging than disclosing a substantial gap.

Step 3: Prepare the materials and commission a third party to conduct a gap analysis.Where possible, conduct a preliminary assessment to identify deficient items. The cost of a preliminary assessment is typically far lower than the expense of correcting major deficiencies after the formal evaluation.

Step 4: Establish continuous records after the application.In fact, these records should begin during Step 3. Record monthly data on energy consumption, water consumption, output, solid waste, and hazardous waste in a standardized format, and use these records to answer all future customer questionnaires.A single record system that serves every customer is the most cost-effective approach.

A Message for Customers

The green factory process is based on public standards, explicit requirements, and a clearly defined path—it is not mysterious. What is mysterious is why many printing plants treat it as a one-time project.

Our recommendation is: treat it as an energy and production data management system, rather than a certificate to be earned.A certificate must be applied for each year, while a well-designed data system can be used for three years and supports cost management, customer sustainability questionnaires, and dual-carbon disclosure.

If a customer asks, “Should our factory do this?”, our usual answer is: “Complete the first step—confirm whether applications are still open this year.”This step costs nothing but determines everything that follows.
