Suppliers of emissions expertise and services

This is a list of companies who have put forward their details as suppliers of emissions expertise and services to the Carbon Neutral Government Programme.

Suppliers and Service Provision

This supplier list is focused on services that support measuring, reporting and verifying greenhouse gas emissions (GHG) and managing and reducing emissions.

Suppliers have been assessed to have capability and experience in one or more of the following areas:

1.1 Advisory services to support the measurement and reporting of GHG emissions in accordance with ISO 14064-1:2018 and / or the Greenhouse Gas Protocol

1.2 Verification services to independently assure GHG statements and inventories, conducted in accordance with ISO 14064-3:2019 or the Assurance Engagements on Greenhouse Gas Statements (ISAE (NZ) 3410) standard

1.3 Verification services which meet third-party accreditation standards or have been assessed and certified by a professional organisation.  Examples of accreditation or certification of verifiers include a professional recognition from the NZICA, a carbon auditor certification from Carbon and Energy Professionals New Zealand (CEP), or organisations accredited to ISO 14065 (accreditation for an assurance provider). 

1.4 Advisory services to analyse, develop, implement, support and manage emissions reduction plans and strategies

1.5 Software solutions or tools or other kinds of support to manage emission reduction plans and strategies.

Many suppliers do not offer both emissions advisory services (1.1) and verification services (1.2 and 1.3) to the same organisation in order to ensure independence in the verification process. Some suppliers internally separate the provision of these services and do offer both. However, this is not common in the market. Consider this when structuring your procurement.

Infrastructure Sustainability Council Yes No No Yes Yes

IS Council is a member-based, not-for-profit peak body operating in Aotearoa New Zealand & Australia.

The Infrastructure Sustainability (IS) Rating Scheme is a voluntary standard for delivering third-party verified sustainability outcomes in infrastructure. An IS Rating is available for all stages from early planning through design and construction, and into operation of assets. Asset categories that can achieve IS rating include transport, water, energy, ports, airports, social infrastructure and green and blue infrastructure. The scheme can assess the sustainability performance of infrastructure at the individual asset level, for portfolios or networks, or even at a regional scale.

The tools cover four sustainability themes – Governance, Economic, Environment and Social, each theme has several credits. A project is scored on sustainability performance in each credit.

The IS scheme is increasingly mandated by procurers across Australia, NZ and beyond (including Waka Kotahi) with over $200B capital value of infrastructure under or having undergone rating, providing a great data set for benchmarking purposes. The tool was assessed by Stanford University as the “most comprehensive and rigorous” rating system of those reviewed.
