Quality Energy
Saving Standard™

A framework for assessing measurable, scientifically grounded and verifiable greenhouse gas emission reductions generated through energy saving.

Measuring the climate impact of energy saving

The Quality Energy Saving Standard™ defines the methodology for generating carbon credits from greenhouse gas emission reductions achieved through energy saving. Energy saving is a key element of long-term sustainability because it substantially influences human society’s emissions into the biosphere.

Energy saving

Energy saving avoids the need to consume energy. The Standard addresses a broad range of energy-saving opportunities and the greenhouse gas emission reductions derived from them.

Process assessment

QESS™ assesses the pre-project state, the relevant technologies and processes, and the material and energy flows required to determine the resulting savings.

CO₂e reduction

QESS™ quantifies the greenhouse gas emission reduction resulting from energy savings using a conservative and verifiable calculation approach.

Energy saving and emission reduction

QESS™ can be applied to a wide range of projects where energy savings generate measurable greenhouse gas emission reductions. The assessment compares the pre-project state with the new state and follows the relevant energy mix and carbon content.

  • Energy-saving projects and activities
  • Technology and process efficiency improvements
  • Energy consumption and energy-mix assessment
  • Pre-project and new-state comparison
  • Material and energy input/output mapping
  • Quantification of annual CO₂e savings

What does QESS™ assess?

The key processes and technologies, energy inputs and outputs, the pre-project state, the new state, the relevant energy mix and carbon content, and the resulting annual greenhouse gas emission savings.

The methodology also requires professional cross-checking of calculations and the use of up-to-date variables.

Openness, credibility and future-proof assessment

QESS™ is designed as a practical, future-proof methodology for stakeholders participating in the Voluntary Carbon Market.

Openness

Appropriate access to relevant basic data and documentation supports independent cross-checking of the credibility of calculations.

Credibility and transparent documentation

Project owners are responsible for the validity, integrity and accuracy of the submitted input data and documentation.

Continuous improvement

Continuous improvement applies to the overall performance of the assessed process, project or program and follows quality, scientific and technological progress.

Toughest sustainability criteria

Full-scale technology mapping, process flow, all input and output materials and energy balances, assessment of the pre-project state, and collection of long-term results with a minimum 100-year perspective.

State-of-the-art technology assessment

Technology description, process flow, inputs, outputs, conservative CO₂e calculations, professional peer cross-checking and up-to-date variables are included in the assessment.

Prevention of double counting

Project ownership of the CO₂ gain and the absence of double use or double registration must be documented. Without the required declaration or evidence, assessment or registration cannot proceed.

From energy saving to CO₂e reduction

The QESS™ process follows the relationship between energy consumption, energy mix, carbon content, the pre-project state, the new state and annual CO₂e savings.

1

Energy mix accounting

Determine the relevant annual energy consumption and the energy mix used by the assessed activity.

2

Past carbon calculation

Establish the carbon content and CO₂ emissions associated with the pre-project energy use.

3

New CO₂ calculation

Calculate the emissions associated with the new state after implementation of the energy-saving activity.

4

CO₂e savings

Determine the annual greenhouse gas emission savings resulting from the change in energy use.

5

QESC™ credit

Convert the verified CO₂e result into the corresponding Quality Energy Saving Credit™.

QESC™ from verified energy savings

The QESS™ Standard defines the methodological framework for generating Quality Energy Saving Credits™, or QESC™.

QESC™

Under QESS™, one carbon credit represents one tonne of CO₂e greenhouse gas emissions in the Voluntary Carbon Market. QESC™ is based on verified greenhouse gas emission reduction achieved through energy saving.

The Standard follows an ex-post financing logic: payment for registered credits is linked to climate benefits resulting from work already done and assessed, rather than a donation, sponsorship or grant for an uncertain future project.

Numeric Counting Model

The QESS™ Numeric Counting Model for crediting is based on the Energy Saving Model and the process flow guiding QESS™ assessment. It provides the framework for the numerical calculation of CO₂e reduction for an implemented energy-saving project.

Each Numeric Counting Model has an iCC-designed calculation table in Excel format. The detailed calculation tables and methodological implementation are iCC intellectual property and are not publicly disclosed under the Standard.

Data quality and conservative approach

QESS™ applies a conservative approach to estimate or derive necessary data in order not to overstate CO₂e elimination, reduction, prevention or sequestration.

  • Energy consumption
  • Energy mix and carbon content
  • Pre-project state
  • New state
  • Annual CO₂e savings
