Services
Greenhouse Gas (Carbon) Audits
We provide independent carbon auditing services all across New Zealand and offer seamless personal assistance from the pre-audit stage right through to the finished assurance report.
Our services and expertise include organisational, community/city, events, and product carbon inventories and carbon footprints (ISO 14064-1, ISO 14067, PCAF, GHG Protocol). We are also a New Zealand Carbon Neutral Government Programme Supplier. Our greenhouse gas audits are conducted in accordance with ISO 14064-3 and NZ SAE 1.
While we don't provide carbon certification, Ekos, an established certification provider, recognises our audits.
Our team is highly qualified, and all full audits are led or overseen by a CEP Certified Carbon Auditor.
Environmental and Sustainability Assurance
Our environmental and sustainability assurance services help you make a credible sustainability claim for your business or product and give you the confidence to report sustainability metrics that have been independently reviewed.
Our services include Aotearoa New Zealand Climate Standards assurance, Airport Carbon Accreditation verification, Eco Choice Aotearoa Ecolabel (formerly Environmental Choice) assessments, ESG stakeholder surveys and returns, Sustainability Linked Loans, GRI reporting, sustainability annual reports, and product stewardship assessments.
We provide verification and validation services to the Ekos SD (BioCredita) biodiversity credit programme.
If a full audit is not required, we also offer independent technical reviews, second party audits and quality reviews.
We pride ourselves in our values:
INDEPENDENCE - INTEGRITY - IMPARTIALITY - TRANSPARENCY
Our independence is fundamental to our assurance work, and is our point of difference in the New Zealand market. We do not provide consultancy, business advisory, sell software solutions or carbon credits related to the assurance services we deliver. This is reducing the risk of bias or conflicts of interest for both the reporter and their Scope 3 suppliers. We have robust conflict-of-interest controls, ethical standards and clear governance processes embedded in our quality management systems to uphold our integrity, maintain impartiality, and promote transparency.
