1. Scope

This document provides a comprehensive list of the Required Interventions that organisations shall implement in accordance with section 4.7.1 of the NoCO2 Net Zero Standard, and outlines the process for their implementation.

2. References

2.1. Normative

The following referenced documents are required for the application of this methodology:

– NoCO2 Net Zero Standard

– ANZSIC Mapping Schedule

2.2. Informative

Individual Intervention Rules cite inline the external documents that are relevant to, or assist with, their implementation.

3. Conventions

To ensure clarity and consistency, this standard uses specific terminology to indicate the nature of the organisation's obligations. The following terms apply throughout the document, where:

– shall indicates a mandatory requirement;

– should indicates a recommendation for best practice; and

– may indicates a permissible action.

4. Terms & Definitions

– ANZSIC: The Australian and New Zealand Standard Industrial Classification system, used as the basis for mapping an organisation's business activities to the industry categories listed in the Required Interventions Schedule via the ANZSIC Mapping Schedule.

– Applicable Year: The reporting period in which an intervention is first determined to apply to the organisation, established through the industry, entity size, and (where relevant) materiality screening processes set out in sections 5.1, 5.2, and 5.3. The Applicable Year is the starting point from which the Implementation Timeframe is counted.

– Fulfillment Year: The reporting period by which an intervention's rule requirements shall be met and against which conformance is assessed. Calculated as the sum of the Applicable Year and the Implementation Timeframe. Failure to meet the Intervention Rule by the Fulfillment Year constitutes a major non-conformance.

– GHG Category: A classification of greenhouse gas emission sources as defined under the NoCO2 Net Zero Standard, encompassing Scope 1 (direct emissions), Scope 2 (purchased energy), and Scope 3 (value chain) categories. Each Required Intervention is associated with a specific GHG Emission Category for the purposes of materiality screening.

– Implementation Timeframe: The deferral, expressed in reporting periods, between when an intervention first applies to the organisation (the Applicable Year) and when its requirements take effect (the Fulfillment Year). An Implementation Timeframe of "current" means requirements take effect in the same reporting period in which the intervention becomes applicable; "+X years" defers the Fulfillment Year by X reporting periods.

– Intervention Rule: The specific, prescriptive requirements set out for a Required Intervention in the Required Interventions Schedule, which the organisation shall implement in full by the Fulfillment Year.

– Materiality Test: The screening process set out in section 5.3.1 by which the organisation determines whether a GHG Emission Category is sufficiently significant—either as a percentage of the organisation's total footprint or in absolute tCO2e—to trigger any associated Materiality-Tested Interventions for the relevant reporting period.

– Materiality-Tested Intervention: A Required Intervention whose applicability depends on the GHG Emission Category to which it relates passing the Materiality Test for the relevant reporting period.

– Net Zero Inventory: The organisation’s total quantified greenhouse gas footprint as measured in accordance with the NoCO2 Net Zero Standard, expressed in tCO2e, against which abatement potential is benchmarked.

– Non-Attributable Inventory (NAI): The organisation's quantified greenhouse gas emissions that fall outside the Net Zero Inventory boundary but remain relevant for disclosure under the NoCO2 Net Zero Standard.

– Non-Materiality-Tested Intervention: A Required Intervention that applies to the organisation regardless of the emissions associated with its GHG Emission Category, provided the industry and entity size criteria are satisfied.

– Reporting Period: The annual period over which the organisation measures and reports its greenhouse gas inventory in accordance with the NoCO2 Net Zero Standard. Used as the unit of time for determining Applicable Year, Implementation Timeframe, and Fulfillment Year.

– Required Interventions: A core abatement measure that, once determined applicable through industry, entity size, and materiality screening, the organisation shall implement within the prescribed implementation timeframe in order to make a net zero claim under the NoCO2 Net Zero Standard.

5. Required Interventions

Required Interventions are obligations that apply to all organisations following the NoCO2 Net Zero Standard.

Required Interventions have been explicitly identified by CRI as having such a strong case for implementation that they shall be implemented by all organisations seeking alignment to the Net Zero Standard. Some activities apply to all organisations, some activities are industry specific, and some only apply to large organisations.

The Required Interventions Schedule details the following key elements per intervention:

– Industry: The sector or industry category that the intervention applies to.

– Entity Size: The entity size (5.2) that the intervention applies to (i.e. small/large).

– Inventory: The Inventory Type (Standard 4.5.2) that the GHG Emission Category (Standard 4.5.3) belongs to (i.e. NZI or NAI)

– GHG Category: The GHG Emission Category the intervention is associated with. Used for materiality screening purposes.

– Intervention Rule: The specific requirements of the intervention that the organisation shall implement.

– Implementation Timeframe: The deferral, in reporting periods, between when an intervention first applies to the organisation and its requirements take effect.

– Justification: The basis by which the intervention was deemed required.

5.1. Industry Assessment

The organisation shall determine the relevant industry categories that are applicable to its operations through referring to the ANZSIC Mapping Schedule, which contains a mapping of ANZSIC codes to industry categories within the Required Intervention Schedule (RIS).

The organisation shall identify each RIS industry category in which it conducts operations, whether via business units, subsidiaries, or functions embedded within broader operations. An RIS industry category shall be deemed relevant where either:

– operations in that industry category generate more than 5% of the organisation's total revenue for the reporting period; or

– expenses attributable to operations in that industry category exceed 5% of expenses, excluding: depreciation, amortisation, cost of sales;

This assessment shall be reperformed in each reporting period, and upon any material change in business activities, including acquisitions and divestments.

Required Activities marked 'Universal' apply to all organisations regardless of industry.

5.2. Entity Size Assessment

The organisation shall determine its Entity Size in accordance with section 4.2.1 of the NoCO2 Net Zero Standard.

An intervention marked "Large" applies only to organisations classified as a large entity. An intervention marked "Small" applies only to organisations classified as a small entity. An intervention marked "All" applies regardless of Entity Size.

5.3. Types of Required Interventions

Required Interventions are classified as two different types:

– Materiality tested Interventions

– Non-materiality tested Interventions

Materiality-tested Interventions are implemented based upon passing the materiality test as per 5.3.1; Non-materiality tested Interventions shall be applicable based on the industry and entity size assessments, but regardless of emissions associated with the corresponding GHG Emission Category.

5.3.1. Materiality Test

The materiality test assesses the size of a given scope/category both relative to the organisation’s total GHG footprint and in absolute terms of tCO2e. An organisation shall comply with a Materiality-tested Intervention if the GHG Category the intervention belongs to either exceeds at least one of the materiality thresholds for the relevant reporting year (as set out in the table below).

The materiality threshold tightens over successive reporting periods. This reflects the principle that as an organisation decarbonises its largest emissions categories, residual categories that were previously immaterial become material in proportional terms. The staggered threshold ensures that all material abatement opportunities are captured by 2040, while avoiding the enforcement of interventions that would deliver immaterial outcomes in earlier periods.

The organisation shall treat the GHG Emission Category as material where emissions associated with it exceed either the materiality percentage or materiality threshold corresponding to the first reporting period starting on or after the dates set out below:

Effective from	Materiality Threshold (%)	Materiality Threshold (tCO2e)
1 Jan 2025	20%	N/A
1 Jan 2030	10%	5,000
1 Jan 2035	5%	2,500
1 Jan 2040	1%	500

The materiality calculation depends on whether the GHG Category is a Net Zero Inventory (NZI) category or a Non-Attributable Inventory (NAI) category:

a) For NZI categories, materiality is the category’s emissions divided by the total Net Zero Inventory.

b) For NAI categories, materiality is the category’s emissions divided by the sum of the total Net Zero Inventory and total Non-Attributable Inventory (NZI + NAI).

5.4. Implementation Timeframe

Each intervention carries a specified implementation timeframe. This is used to determine the reporting period in which the rule requirements shall be met by and assessed for conformance, known as the Fulfillment Year. Per intervention, the organisation shall determine the following attributes:

i) Applicable Year: The year of the reporting period that the intervention first met the requirements was deemed applicable.

– Interventions are deemed applicable to the organisation as per the screening processes of sections 5.1, 5.2, and 5.3.

ii) Implementation Timeframe: The number of reporting periods added to the applicable year, as defined by the Required Interventions Schedule (5.5).

iii) Fulfillment Year: The reporting period by which the requirements of the intervention shall be met, calculated as the sum of the Applicable Year and Implementation Timeframe.

The organisational shall implement the requirements as defined by the Intervention Rule, by the reporting period as represented by the Fulfillment Year.

Note: The Implementation Timeframe is used to determine the reporting period in which the rule requirements shall be met and assessed for conformance i.e. the Fulfillment Period.

For rules with an Implementation Timeframe of "current", the Fulfillment Period equals the Applicable Year. Such rules may require actions relating to historical activities within the reporting period currently being assessed, such as purchasing of renewable energy attribute certificates to address historical grid electricity purchases.

For rules with an Implementation Timeframe of "+X years", the Fulfillment Period falls X reporting periods after the Applicable Year. For example, an intervention with an implementation timeframe of "+2 years" that was deemed applicable in the 2028 reporting period, has a Fulfillment Period of 2030, and the rule requirements shall be met within the 2030 reporting period and onwards, with failure to do so constituting a major non-conformance.

The organisation should note that where reporting is performed during a subsequent reporting period, the implementation runway is effectively reduced. For example, an organisation completing its 2028 report midway through the 2029 reporting period would have less than one full reporting period in which to implement an intervention with a "+2" implementation timeframe before it takes effect.
