Carbon Measurement
Accurate carbon measurement is the foundation of every credible sustainability programme. NetNada provides comprehensive emissions calculation across Scope 1, 2, and 3—aligned with the GHG Protocol Corporate Standard—using activity-based and spend-based methodologies with Australian and international emission factors. From a single site to a global supply chain, measure what matters.
How It Works
Carbon measurement with NetNada follows a structured approach: define your organisational boundary, collect activity data, apply appropriate emission factors, and calculate your footprint across all relevant scopes and categories. Each step builds on established standards, ensuring your measurements are defensible and comparable.
Define Your Organisational Boundary
Set your consolidation approach—operational control, financial control, or equity share—in line with GHG Protocol requirements. Configure your organisational structure including business units, facilities, and operational sites. NetNada maps your corporate hierarchy to emission boundaries automatically.
Collect Activity Data
Gather activity data across all emission sources: fuel consumption, electricity usage, refrigerant losses, fleet operations, business travel, purchased goods, and more. NetNada supports manual entry, spreadsheet imports, direct integrations with utility providers, and automated data feeds from accounting systems like Xero.
Apply Emission Factors
NetNada's emission factor library includes Australian NGA Factors, international databases (DEFRA, EPA, ecoinvent), and industry-specific factors. The platform selects appropriate factors based on your activity data, location, and methodology choices. Custom factors can be added for specific processes or products.
Calculate Across All Scopes
Scope 1 direct emissions from owned or controlled sources. Scope 2 indirect emissions from purchased energy (both location-based and market-based methods). Scope 3 value chain emissions across all 15 categories. NetNada calculates each scope with the methodology appropriate to your data quality and reporting requirements.
Review, Validate, and Report
Review calculated emissions with built-in validation checks that flag anomalies, data gaps, and methodology inconsistencies. Compare results against previous periods and industry benchmarks. Export your carbon footprint data for use in NGER, AASB S2, CDP, Climate Active, and other reporting frameworks.
Why Use NetNada for Carbon Measurement
GHG Protocol Aligned
NetNada follows the GHG Protocol Corporate Accounting and Reporting Standard—the global benchmark for carbon measurement. Your emissions inventory is structured, calculated, and reported in accordance with the framework that underpins virtually every climate reporting obligation.
Complete Scope Coverage
Measure across all three scopes and all 15 Scope 3 categories. NetNada supports the full breadth of emission sources Australian businesses encounter—from stationary energy and transport (Scope 1) through purchased electricity (Scope 2) to supply chain, travel, and waste (Scope 3).
Australian Emission Factors Built In
Pre-loaded with National Greenhouse Accounts Factors including state-based electricity factors, Australian fuel factors, and local transport factors. No need to source, convert, or manually update Australian emission factors—they're maintained and updated within the platform.
Multiple Methodology Support
Choose the right methodology for your data quality: activity-based calculations for high-accuracy measurement using actual consumption data, or spend-based estimation when activity data isn't available. Progress from spend-based to activity-based as your data maturity improves.
Single Source of Truth
Your carbon footprint data feeds directly into NGER, AASB S2, CDP, Climate Active, and SBTi reporting. Calculate once, report everywhere. No reconciliation issues between frameworks, no inconsistent figures across disclosures.
Scalable from SME to Enterprise
Whether you're a single-site SME measuring for the first time or a multi-national enterprise with complex Scope 3 supply chains, NetNada scales to your needs. Start simple with spend-based estimates and grow into sophisticated activity-based measurement as your programme matures.
Who Uses Carbon Measurement
Organisations Beginning Their Carbon Journey
First-time carbon measurement can be overwhelming. NetNada's guided workflows help you define boundaries, identify emission sources, and calculate your initial footprint without needing deep technical expertise. Start with what you have and improve over time.
Sustainability Teams at Mid-Size Companies
Growing companies facing increasing stakeholder expectations need reliable carbon measurement. NetNada provides the rigour required for credible disclosure while remaining practical for teams that don't have dedicated carbon accounting specialists.
Large Enterprises with Complex Operations
Multi-site, multi-country operations require sophisticated carbon measurement with consistent methodology across business units. NetNada handles complex organisational structures, multiple consolidation approaches, and diverse emission source profiles.
Companies Preparing for Mandatory Disclosure
AASB S2 mandatory climate disclosure requires robust carbon measurement as the foundation for Metrics & Targets pillar disclosures. NetNada ensures your measurement methodology meets the standard of assurance-ready data that mandatory reporting demands.
Advisors and Consultants
Sustainability consultants managing carbon measurement for multiple clients benefit from NetNada's standardised methodology, multi-client architecture, and efficient data management. Deliver consistent, high-quality carbon footprints across your advisory portfolio.
Carbon Measurement Features
Scope 1 Direct Emissions Calculator
Calculate emissions from fuel combustion, fleet vehicles, refrigerant losses, and industrial processes under your operational control. Supports all major fuel types, refrigerant gases, and process emissions with Australian emission factors.
Scope 2 Dual-Method Calculator
Calculate purchased energy emissions using both location-based (grid average) and market-based (contractual) methods as required by GHG Protocol. Supports state-based Australian electricity factors and renewable energy certificate accounting.
Scope 3 Value Chain Calculator
Measure indirect emissions across all 15 GHG Protocol Scope 3 categories—from purchased goods and services through business travel, employee commuting, and end-of-life treatment. Activity-based and spend-based methodologies available per category.
Emission Factor Library
Comprehensive library including Australian NGA Factors, UK DEFRA factors, US EPA factors, and ecoinvent lifecycle data. Factors update automatically when source databases are revised. Add custom factors for proprietary processes or EPD-verified products.
Activity-Based Calculations
Highest-accuracy methodology using actual consumption data—kWh of electricity, litres of fuel, kilometres travelled. NetNada guides you to collect the right activity data for each emission source and applies appropriate conversion and emission factors.
Spend-Based Estimation
When activity data isn't available, estimate emissions from financial expenditure using economic input-output emission factors. Ideal for Scope 3 categories where supplier-specific data is limited. Clearly flagged as estimates with guidance on transitioning to activity-based.
Organisational Boundary Configuration
Define your consolidation approach and map your corporate structure to emission boundaries. Handle operational control, financial control, and equity share approaches. Manage boundary changes over time with appropriate recalculation.
Data Validation and Quality Scoring
Automated validation flags anomalies, missing data, and methodology inconsistencies. Data quality scores for each emission source indicate confidence levels. Prioritise data improvement efforts where they'll most improve overall measurement accuracy.

"NetNada gave us our first comprehensive carbon footprint across all three scopes. We knew our Scope 1 and 2 numbers, but Scope 3 was always a black box. The spend-based methodology let us get started immediately, and we're progressively moving to activity-based as we engage suppliers. Having one platform for all three scopes is essential."
- First complete Scope 1, 2, and 3 carbon footprint calculated
- Scope 3 measured across 8 of 15 categories in first year
- Progressive transition from spend-based to activity-based methodology
"The emission factor library saved us enormous time. We operate across Australia and New Zealand, and NetNada automatically applies the correct state-based electricity factors, local fuel factors, and country-specific emission coefficients. No more manually sourcing and converting emission factors from government databases."
- Emission factors automatically applied across AU and NZ operations
- Factor updates incorporated without manual research
- Consistent methodology across 12 office locations
"We started with basic spend-based estimates for our first carbon footprint and have been improving data quality every year. NetNada's data quality scoring shows us exactly where to focus—which categories are still estimated and which now use actual activity data. It's a clear pathway from rough measurement to assurance-ready accuracy."
- Data quality improved from 40% to 78% activity-based in two years
- Carbon footprint feeds NGER, Climate Active, and AASB S2 reporting
