QTCS™ · VERSION 4.0 · JULY 2026

Quality Technology
Change Standard™

A framework for evaluating measurable and verifiable greenhouse gas mitigation resulting from technology change and innovation.

Technology innovation. Measurable climate impact.

The Quality Technology Change Standard™ provides a structured framework for evaluating greenhouse gas mitigation resulting from the implementation of new, improved, replacement or disruptive technologies.

Technology Change

QTCS™ focuses on projects where technological innovation replaces or improves an existing process, system or technology.

Measurable Results

Climate benefits must be supported by measurable and scientifically justified greenhouse gas assessment.

Credibility

Transparency, documentation, independent assessment and the prevention of double counting are central principles of the framework.

What kind of projects can QTCS™ evaluate?

QTCS™ is designed for a broad range of technology-driven climate mitigation activities.

  • Energy efficiency technologies
  • Industrial technology upgrades
  • Low-carbon production technologies
  • Fossil energy replacement
  • Energy conversion and storage systems
  • Resource efficiency technologies
  • Innovative and disruptive technologies
  • Other technology changes with measurable climate benefits

The key question

Innovation alone is not sufficient. The relevant question is whether a technology change produces a real, measurable and verifiable greenhouse gas benefit compared with an appropriate reference scenario.

Built around credibility and measurable impact

QTCS™ applies a structured approach to the assessment of technology-driven greenhouse gas mitigation.

Measurability

Climate benefits must be supported by relevant data and scientifically justified assessment.

Verifiability

Project documentation and results must be suitable for professional and independent review.

Transparency

Relevant project information and assessment documentation should remain traceable throughout the process.

Conservative Approach

Uncertainty must not result in the overestimation of greenhouse gas mitigation.

Additionality

Climate benefits must be assessed in relation to an appropriate project context and reference scenario.

No Double Counting

The same greenhouse gas mitigation outcome must not be claimed or used multiple times.

From technology change to verified climate results

QTCS™ provides a structured assessment framework connecting technological innovation with measurable greenhouse gas mitigation.

1

Project

Technology change is defined and documented.

2

Assessment

Relevant processes, boundaries and data are evaluated.

3

Quantification

Greenhouse gas mitigation is determined using the applicable QTCS™ framework.

4

Verification

Project results may be subject to independent professional review.

5

QTCC™

Verified eligible climate results may become the basis for carbon credit issuance.

From verified climate benefit to QTCC™

QTCS™ provides the framework within which eligible and verified technology-driven greenhouse gas mitigation may form the basis for Quality Technology Change Credits™.

QTCC™

A Quality Technology Change Credit™ represents one metric tonne of verified greenhouse gas mitigation expressed in carbon dioxide equivalent.


QTCC™ credits are intended to reflect real, measurable and verifiable climate results generated through eligible technology change projects.
