Carbon Management

If you don't measure it you can't manage it

The team at Zephyr understands the challenges presented by greenhouse gas reduction targets for 2030 and 2050. We offer a comprehensive decarbonisation advisory service, including:

  • Net Zero road maps 

  • Decarbonisation plans 

  • Advice on appropriate, defensible and effective carbon offsetting / insetting solutions

  • Carbon management public statements, such as the taskforce for Climate-related Financial Disclosure (TCFD) and carbon-related aspects of the Equator Principles

  • Climate change risk assessments for both transitional and physical climate risks

  • Greenhouse Gas Assessments consistent with sate Guides for Large Emitters

  • Independent Expert Reviews for projects with scope 1 and 2 emissions exceeding 100,000 t CO2-e per year

  • Climate change mitigation and adaptation plans

  • Scope 1-3 greenhouse gas inventory development

  • Climate Active assurance / advisory.​​​​​​​​​​​​

​

For three decades, our team has applied scientific rigour in greenhouse gas management, including the measurement, reporting and verification of greenhouse gas emissions and  abatement activities.

Tracking methane emissions​

Zephyr is actively involved in frontier and novel research related to atmospheric measurement. We specialise in the application of cutting edge techniques for fugitive methane monitoring, including the use of satellite, open path, static and drone survey techniques.

Carbon & methane relevant projects  

Reasonable Assurance Audits of Carbon Credit Claims

We conducted reasonable assurance audits for the Australian Clean Energy Regulator across a range of industrial and vegetation‐based carbon crediting methods. Projects included plantation and regeneration activities, methane avoidance and fuel switching, Savanna fire management methods, industrial and commercial emissions reduction method, and commercial lighting method.

Greenhouse Gas Measurement, Reporting and Verification Services

We undertook advanced MRV activities supported by our in‐house R&D program. Our work included quantifying fugitive methane using a range of technologies such as satellite data, open‐path analysers, flux chambers and drone‐based measurement techniques. These methods were applied across sectors including waste management, agriculture, open‐cut coal mining, Oil & Gas and CCS.

Greenhouse Gas Audits under the National Greenhouse and Energy Reporting Scheme

As an accredited lead auditor, we completed multiple audits of major greenhouse gas emitters across Australia, including black coal power generation, underground coal mining, and coal seam gas and landfill gas operations.

Detailed Scope 3 Greenhouse Gas Inventory Development

We delivered a comprehensive analysis of upstream and downstream Scope 3 emissions for a vertically integrated thermal power provider. The work aligned emissions sources with the GHG Protocol, industry factors and relevant calculation methodologies. We also developed a tailored internal Scope 3 calculator to support ongoing reporting.

Expert GHG Advice to a Safety and Environmental Management Authority

We provided expert technical advice as part of an assessment team reviewing Environmental Plans for offshore petroleum activities. Our role included the evaluation of greenhouse gas and air emissions impact assessments to inform regulatory decision‐making.

Methane Flux Monitoring at a Legacy Landfill

We measured methane flux at a legacy landfill to estimate gas collection efficiency. Drone surveys were used to identify emissions hotspots, and flux chambers provided surface emission measurements. Collection efficiency was calculated by comparing measured emissions with known gas flows to on‐site engines.

Fugitive Methane Emissions Research & Development

We completed a multi‐stage research program involving methane monitoring at active coal mines and landfills. Techniques trialled included satellite data interrogation, flux chamber surveys, open‐path monitoring and multiple drone based methods. A co‐location study and comparison across ten technologies informed the development of an optimised emissions quantification methodology
