Oxygen Consulting

What Oxygen Consulting does

Oxygen Consulting is a New Zealand-based sustainability consultancy founded in 2019 and headquartered in Albany, Auckland, operating as Oxygen Consulting NZ Ltd. The firm provides climate, nature and sustainability advisory services to enterprise and mid-market organizations across New Zealand and Australia, with a documented client roster spanning more than 60 organizations across 18+ industry verticals including retail (OfficeMax), fintech (Smartpay), food manufacturing (Tegel Foods, My Food Bag), pharma (AFT Pharmaceuticals), ports (Lyttelton Port, Napier Port), media (NZME, Stuff, Trade Me), and insurance (AA Insurance).

The firm's core technology is a sustainability consulting methodology built on deep expertise in NZ Climate Standards (NZ CS 1, 2, 3), GHG Protocol, ISO 14064-1:2018 / 14064-3:2019, ISSB standards, SBTi, TCFD, and B Corp Certification frameworks. Its differentiated offerings include a proprietary Carbon Neutral Accreditation Programme that benchmarks organizational emissions against best-practice standards, and an annual longitudinal research product — 'Insights on Aotearoa New Zealand Sustainability Professionals' — conducted in partnership with Auckland University of Technology (AUT), the Sustainable Business Council (SBC), and the Sustainable Business Network (SBN). The firm operates six interconnected service lines: Carbon, Climate and Nature; Sustainability Strategy and Advisory; Disclosure and Reporting; Audit and Assurance; Capability Development; and Market Insights.

The business model is a sales-led, project-based professional services engagement model with custom quote-based pricing and multi-year contracts typical of NZ boutique advisory. Revenue derives from direct consulting engagements with NZX/ASX-listed companies and mid-market organizations seeking climate disclosure compliance, GHG measurement and reduction, B Corp certification, sustainability strategy, audit and assurance, and capability development. The firm does not sell software; it monetizes human advisory expertise. It is founder-led (Sarah Holden, 25 years' climate experience), Certified B Corporation since July 2023, and was recognized as a finalist for Excellence in Sustainability at the 2025 2degrees Auckland Business Awards.

Regional players

• Tonkin + Taylor: NZ environmental and engineering consultancy providing climate, sustainability, and environmental impact services. Adjacent competitor in NZ-listed sustainability advisory.
• BECA: Large NZ-headquartered engineering and advisory consultancy with a sustainability and climate resilience practice. Comparable on NZ-listed advisory work but with broader engineering footprint.

Direct peers

• Persephone Advisory: Boutique sustainability and climate strategy consultancy serving Australian and regional clients on climate disclosure, net-zero roadmaps, and ESG advisory — closely comparable service mix and customer segment.
• Toitū Envirocare: Toitū Envirocare is a NZ-headquartered carbon and environmental consultancy offering carbonreduce certification, GHG inventories, and disclosure support. Direct peer to Oxygen on NZ Climate Standards and carbon advisory work for the same listed-company buyer.
• Pollination: Global climate advisory and investment firm with deep APAC roots, providing climate strategy, transition planning, and disclosure support to corporates and financial institutions. Comparable end-to-end sustainability advisory offering and listed-company client base.
• Carbonsync: Australian climate consulting firm focused on science-based target setting, net-zero strategies, and climate disclosure for ASX-listed companies. Directly comparable scope and customer segment to Oxygen's NZ CS 1, 2, 3 practice.

Others

• Akina: NZ social enterprise and sustainability support organization that delivers advisory and capability-building services to mission-driven organizations — adjacent rather than directly competing with Oxygen's listed-company climate disclosure practice.

Broad incumbents

• Sphera (formerly thinkstep-anz): Global ESG and sustainability software plus advisory firm that supports GHG accounting and climate disclosure at scale. Overlaps Oxygen's GHG inventory and disclosure work but adds productized software scope.
• ERM (Environmental Resources Management): World's largest pure-play sustainability consultancy, operating across ANZ. Overlaps with Oxygen's carbon, nature, and disclosure advisory but at vastly greater scale and industry breadth.
• KPMG New Zealand (Sustainability Practice): Big 4 firm delivering climate-related disclosure readiness, ESG assurance, and transition planning to NZX-listed issuers — competing directly for the same NZ CS disclosure mandates, often bundled with audit.
