Don't let carbon liabilities lock you out of your supply chain.
Sustainability is no longer just an environmental goal—it is a commercial requirement. We build data-backed carbon roadmaps that protect your market access, satisfy your biggest customers, and make financial sense.
Carbon strategy that protects your bottom line.
Your biggest customers, export partners, and even your banks are starting to demand verified carbon data. If you cannot prove your emissions reduction pathway, you risk losing market access to competitors who can.
At DETA, our decarbonisation services go beyond generic "green" advice. We treat carbon as a measurable operational liability. Our engineering and sustainability consultants help heavy industry, manufacturing, and commercial sectors across New Zealand and Australia transition to low-carbon operations profitably.

Our Carbon Management & Decarbonisation Services
Carbon Footprint Baselining & Lite Audits
You cannot manage what you have not measured. For businesses at the start of their journey, or those needing immediate data for a tender submission, we provide a robust, cost-effective baseline of your current emissions.
- Scope 1, 2, and 3 emissions baselining and boundary setting.
- High-level identification of quick-win reduction opportunities.
- Compliance checks against local carbon reporting standards.
Comprehensive Decarbonisation Roadmaps
For large, energy-intensive sites, we design the long-term engineering and financial strategy required to hit your 2030 and 2050 targets. We don't just tell you to "electrify"—we model the grid capacity, the capital cost, and the payback period.

- Detailed carbon reduction management plans and modeled pathways.
- Feasibility studies for low-carbon technologies (biomass, high-temperature heat pumps, renewable integration).
- Capital investment planning and government grant (EECA/ARENA) alignment.
- Integration of energy efficiency and carbon management into your core business strategy.
Why CFOs and Operations Managers trust DETA
We model the financials
We know that a carbon strategy is useless if it cannot be funded. We build business cases that bridge the gap between engineering feasibility and financial viability.
Engineering reality, not greenwashing
Our sustainability consultants work alongside our process and mechanical engineers. If we put a decarbonisation target on a roadmap, we know exactly how to physically build it on your site.
Proven Results Across NZ & Australia
We have helped businesses of all sizes, from heavy industrials to food manufacturers, reduce emissions and build long-term carbon resilience.
Unbiased, Vendor-Agnostic Advice
We sell independent engineering expertise, not equipment. Because we aren't tied to any specific brand or supplier, we recommend the best low-carbon technology for your specific site, ensuring you get the right solution without the sales pitch.
We were thrilled to work with the DETA team. Their work has enabled us to gain a comprehensive understanding of our energy consumption and has identified a range of priority demand reduction opportunities for our site
