Carbon reporting and emissions accounting
Measuring and reporting greenhouse gas emissions so your organisation can disclose and reduce with confidence.
Carbon reporting is the disciplined measurement and disclosure of an organisation's greenhouse gas emissions. It underpins net-zero commitments, sustainability disclosures, and supply chain requests, and it is increasingly expected by investors, customers, and regulators. Environmental Specialists Australia helps clients build emissions inventories across Scope 1 direct emissions, Scope 2 purchased energy, and the Scope 3 emissions that sit across their value chain. We work from activity data — fuel, electricity, materials, travel, and waste — applying recognised emission factors to produce a defensible carbon footprint.
Getting the boundaries and methodology right matters as much as the numbers themselves. Australian organisations operate within frameworks such as the National Greenhouse and Energy Reporting scheme and the Greenhouse Gas Protocol, and inconsistent methods make year-on-year comparison and disclosure unreliable. Our consultants set clear organisational and operational boundaries, document assumptions, and structure inventories so they can be repeated consistently and stand up to scrutiny. The result is a reporting foundation that supports credible public claims and genuine emissions reduction rather than one-off estimates.
When is this service required?
- Organisations making net-zero or emissions reduction commitments
- Businesses responding to customer or supply chain emissions requests
- Entities preparing sustainability or climate-related disclosures
- Companies approaching National Greenhouse and Energy Reporting thresholds
- Projects needing an emissions baseline for approval or grant conditions
- Organisations establishing a repeatable annual reporting process
Our process
- Boundary setting: Definition of organisational and operational boundaries and the scopes to be included in the inventory.
- Data collection: Gathering of activity data covering energy, fuel, materials, travel, and waste across the reporting period.
- Emissions calculation: Application of recognised emission factors to produce Scope 1, 2, and where relevant Scope 3 estimates.
- Review and documentation: Quality review of results with clear documentation of methods and assumptions for repeatability.
- Reporting: Preparation of an emissions report suited to internal use, disclosure, or supply chain response.

Frequently asked questions
- What are Scope 1, 2, and 3 emissions?
- Scope 1 covers direct emissions from sources you own or control, such as fuel combustion. Scope 2 covers indirect emissions from purchased electricity, heat, or steam. Scope 3 covers all other indirect emissions across your value chain — purchased goods, travel, waste, and use of products — and is often the largest but hardest category to measure.
- Do I have to report carbon emissions in Australia?
- It depends on your size and activities. Organisations meeting National Greenhouse and Energy Reporting thresholds have mandatory obligations, and disclosure requirements are expanding for larger entities. Many organisations also report voluntarily to meet customer, investor, or supply chain expectations even where no legal obligation applies.
- How accurate does a carbon inventory need to be?
- Accuracy should be proportionate to how the numbers will be used. Disclosure and public claims demand more rigorous data and documented methods, while an initial internal baseline can start with reasonable estimates and improve over time. We set an appropriate level of detail and identify where data quality can be strengthened.
- How does carbon reporting relate to a net-zero strategy?
- Carbon reporting provides the measurement foundation; a net-zero strategy sets the reduction pathway. You cannot credibly set or track targets without a reliable inventory. We often prepare the reporting first, then use that baseline to inform reduction planning and target setting.
