What ISO 14034 Verification Provides

ISO 14034 enhances both vendor credibility and buyer confidence by ensuring that technology performance claims are scientifically valid, independently tested, and presented in a clear, standardized format. By grounding performance data in high-quality, third-party evaluation, the standard gives stakeholders the clarity they need to compare solutions, assess value, and make informed decisions. This level of transparency helps technologies stand out in competitive markets and supports stronger communication with customers, regulators, and investors.

  • Independent Proof That Drives Adoption

Why ETV Matters

Environmental Technology Verification plays a critical role in reducing risk and accelerating the adoption of innovative solutions. For technology developers, ETV provides a trusted way to demonstrate real-world performance, differentiate from competitors, and gain traction in procurement, permitting, and investment processes. For buyers and regulators, it offers reliable evidence that a technology performs as claimed, enabling confident decisions without uncertainty. By validating performance before widespread deployment, ETV helps new technologies enter markets faster, build trust more effectively, and achieve greater national and international recognition.

Phases of the Performance Measurement and Verification Procedure

The ETV / ISO 14034 process consists of three main phases:

Phase 1

1.1 Pre-screening to determine eligibility
Verification of a technology performance claim requires the proponent to provide reliable, high quality data on the technology. For a technology to be eligible for verification, the performance claim must be specific and unambiguous. The claim must clearly specify the minimum and maximum performance that is achievable with the technology. The performance claim must also clearly specify the applicable operating conditions and be measurable using acceptable test procedures and analytical techniques. The data must be collected by an independent, third-party test agent and analyzed by an independent, accredited laboratory.

Pre-screening checklist:

  • Alignment with priorities
  • Environmental benefits
  • Commercial readiness
  • Potential for market replication
  • Requirements for performance testing and verification – i.e., suitability of test plans (or need to develop), credibility of available data (or need for additional testing)
  • Level of effort and cost to client

1.2 Formal application for verification
Before confidential information is provided to GLOBE Performance Solutions and its associated testing and verification organizations, potential conflicts of interest must be resolved and a confidentiality agreement must be signed. The testing and verification organizations may be selected from the list of GLOBE Performance Solutions Consortium members. In some cases other testing and verification organizations may be selected based on the requirements for specific technology expertise.

1.3 Stakeholder input and guidance
Stakeholder engagement and involvement are basic requirements for ensuring that local needs and related social impacts are adequately addressed in the determination of relevant performance parameters for performance verification.

Phase 2

2.1 Independent, third-party testing organization
Testing and preparation of the test report is conducted by an independent testing organization. Specific high-quality data is required to determine the performance of the technology. The testing organization reviews the proposed performance parameters and any available technology-specific test results to determine whether additional data is required. The data related to the technology must be of sufficient quality and quantity to permit statistical analysis of the data at a 95% confidence level.

2.2 Technology-specific test plan
The testing organization must be independent from the technology proponent (e.g., vendor). The test plan used to generate the performance data should be assessed against the test design required for the verification. The testing procedure must include a quality management plan to ensure compliance with the test data quality requirements. An audit of the test agent and analytical laboratory that generated the data may be required to show compliance with quality management system requirements.

2.3 Performance testing operating conditions
A verified claim is only valid if the technology is operated within the specified operating conditions. Data collected to support the technology performance claim must be collected within appropriate ranges of key operating parameters. Operating conditions during the testing must be monitored and documented to ensure that they are within the ranges defined in the experimental design. Information must be provided on the actual key operating variables during the test and the methodology used to monitor and document these conditions.

2.4 Sample size
The type of sample collected must be appropriate to generate data that can be used to verify the performance of the technology. Samples must be collected after sufficient time has elapsed to allow the process to stabilize, and to ensure that the samples are representative of the typical process characteristics at the sampling locations. The number of samples must be sufficient such that when the data supporting the claim is statistically analyzed, the claim can be accepted. The number of data required in any data set to be statistically acceptable will depend on the variability in the data and the nature of the technology and its application. It is the responsibility of the applicant to ensure that a sufficiently large number of data points are provided, with a sufficiently small variability, to be statistically acceptable. Acceptable sampling procedures or protocols must be used to collect and preserve samples including field and reagent blanks. Standard reference materials are required. All procedures and protocols must be applied by competent testing organization.

2.5 Analytical laboratory protocols
The laboratory that analyzes the samples must be independent from the applicant, and accredited (under ISO 17025) by a recognized certification agency for the specific parameters being analyzed. In Canada, acceptable laboratory accreditation to the applicable technical testing scope must be earned from the Canadian Association of Environmental Analytical Laboratories (CAEAL), the Standards Council of Canada (SCC), or a signatory to the International Laboratory Accreditation Cooperation.

2.6 Chain of custody
Chain of custody refers to the ability to trace the possession and handling of the sample from the time of collection through analysis and final deposition to ensure the integrity of the process from sample collection to data reporting. Chain-of-custody reporting is used in routine control of sample flow, and in litigation if required. Acceptable chain of custody for sample analysis may include sample labels, sample seals, sample submission sheets, sample receipt log and assignment for analysis.

2.7 Quality assurance
Testing under actual operating conditions is required following an established test plan and prescribed methodologies. The instruments used to measure the operating parameters must be calibrated regularly to ensure that the instruments are providing accurate, reliable readings and these calibrations must be documented. Acceptable quality assurance/quality control (QA/QC) procedures must be used for sample collection and analysis. For sampling, QA/QC may include the use of blanks, spiked samples and replicate samples as well as inter-laboratory studies and use of standard reference materials.

2.8 Performance testing report
A test report is produced highlighting the test plan, methods used, results achieved, observations, and conclusions. The data must demonstrate that the technology has a measurable effect on the specific parameter(s) identified in the performance claim.

Phase 3

3.1 Independent verification organization
Verification and preparation of the verification report is conducted by an independent verification organization. Verification of the technology requires specific and high-quality data to determine the performance of the technology.

3.2 Verification based on an internationally accepted GVP
A general verification protocol (GVP) is used by the independent verification organization that is responsible for reviewing and verifying data and information that support the technology performance claim. The GVP contains an overview of the verification process, instructions for review of the technology, and a series of checklists that provide guidance to ensure that a comprehensive examination is undertaken. The GVP guides the verification organization through the process of determining the mandatory criteria (i.e., scientific soundness, absence of conflict of interest, environmental benefits) and requires an expression of the limitations of the technology, as well as validation of the actual performance data.

3.3 Determination of 95% statistical confidence
The verification organization reviews the proposed performance parameters and the technology-specific test results to determine whether the data meets the objectives of the verification process. The data related to the technology must be of sufficient quality and quantity to permit statistical analysis of the data at a 95% confidence level. Statistical analysis worksheets are used to support this determination.

3.4 Reporting
The client receives a certificate of verification, a verification fact sheet and a verification report. The certificate does not constitute a guarantee of performance.
