Scope 2 Location-Based Calculator
Calculate your Scope 2 purchased electricity emissions using grid-average emission factors for each Australian state and territory. NetNada applies the latest National Greenhouse Accounts (NGA) factors for NSW, VIC, QLD, SA, TAS, WA, NT, and ACT — giving you the location-based half of the dual reporting required by GHG Protocol, CDP, AASB S2, and Climate Active.
How It Works
Location-based Scope 2 reflects the average emissions intensity of the electricity grid where your facilities operate. It uses grid-average emission factors published by the Australian Government through the National Greenhouse Accounts — the same factors required for NGERS reporting. This provides a consistent, comparable measure of electricity emissions regardless of contractual arrangements.
Enter Electricity Consumption by Site
Input electricity consumption in kilowatt-hours (kWh) for each facility. Upload electricity bills, import from energy management systems, connect to utility portals, or enter data manually. NetNada accepts monthly, quarterly, or annual consumption data and supports both interval metering and billing-period totals.
Assign Grid Regions to Each Site
Map each facility to its electricity grid region. For Australian sites, this means the relevant NEM state (NSW/ACT, VIC, QLD, SA, TAS), WA's SWIS grid, or NT grids. NetNada auto-assigns grid regions based on site postcodes and maintains the mapping as you add new facilities. International sites use country or regional grid factors.
Apply NGA Grid-Average Emission Factors
NetNada applies the current National Greenhouse Accounts emission factors for each grid region. These factors are updated annually when the Australian Government publishes new NGA tables. Both Scope 2 (indirect) and Scope 3 (transmission and distribution losses) factors are applied separately for complete reporting.
Calculate Location-Based Scope 2 Emissions
For each site: emissions (tCO2e) = electricity consumed (kWh) multiplied by the grid-average emission factor (kg CO2e/kWh) for that region. NetNada aggregates across all sites, breaks down by state and grid region, and presents results in tonnes of carbon dioxide equivalent (tCO2e).
Compare with Market-Based and Generate Reports
View location-based results alongside market-based calculations for GHG Protocol dual reporting. Understand the difference — location-based shows your grid context, market-based shows your procurement choices. Export reports formatted for NGERS, CDP, Climate Active, and AASB S2 disclosure requirements.
Why Use Scope 2 Location-Based Calculator
Meet GHG Protocol Dual Reporting Requirements
The GHG Protocol Scope 2 Guidance (2015) requires organisations to report both location-based and market-based Scope 2. Location-based is mandatory — it provides the grid-average baseline that contextualises any market-based renewable energy claims. Without it, your Scope 2 reporting is incomplete.
Use Authoritative Australian Emission Factors
NetNada applies emission factors directly from the National Greenhouse Accounts (NGA), published by the Australian Department of Climate Change, Energy, the Environment and Water. These are the same factors required for NGERS reporting and accepted by all major frameworks operating in Australia.
Understand Regional Grid Differences
Australian grid emission factors vary significantly by state: Tasmania's hydro-dominated grid has dramatically lower emissions than coal-heavy NSW or QLD. Location-based calculation reveals which sites have the highest emissions intensity, informing decisions about energy efficiency investments and site-level renewable energy procurement.
Satisfy NGERS Reporting Obligations
National Greenhouse and Energy Reporting Scheme (NGERS) uses location-based methodology with NGA factors. NetNada's location-based calculator produces NGERS-compliant Scope 2 figures, saving time when preparing your annual NGER report and ensuring consistency between voluntary and mandatory disclosures.
Enable Meaningful Year-on-Year Comparisons
Location-based emissions provide a consistent metric for tracking electricity efficiency improvements over time. Because grid-average factors are independent of procurement choices, changes in location-based Scope 2 reflect genuine changes in consumption — energy efficiency, site closures, or growth.
Complement Market-Based for Complete Picture
Location-based and market-based serve different purposes. Location-based shows physical grid reality — useful for regional comparisons and energy efficiency tracking. Market-based shows procurement choices — useful for renewable energy credit. Together they tell the complete Scope 2 story that sophisticated stakeholders expect.
Who Uses Scope 2 Location-Based Calculator
NGERS Reporters
Organisations reporting under the National Greenhouse and Energy Reporting Scheme need location-based Scope 2 calculated with NGA factors. NetNada produces NGERS-compliant figures directly, ensuring consistency between your regulatory submission and voluntary disclosures.
Organisations Beginning Emissions Reporting
Location-based is the simplest starting point for Scope 2 calculation — you need electricity consumption data and your site locations. No renewable energy certificates or contractual instruments required. Most organisations start here and add market-based as they develop renewable procurement strategies.
Multi-Site Businesses Across Australia
Companies with facilities in multiple states benefit from seeing how grid emission factors affect their Scope 2 profile. A Melbourne office and a Sydney warehouse have very different electricity emissions per kWh. Location-based calculation reveals these differences and informs site-level energy strategy.
Energy Efficiency Programme Managers
Location-based Scope 2 is the right metric for tracking energy efficiency improvements. Because it uses grid-average factors regardless of procurement, reductions in location-based emissions reflect genuine consumption decreases — not renewable certificate purchases. Ideal for measuring the impact of LED upgrades, HVAC optimisation, or building retrofits.
CDP and AASB S2 Reporters
Both CDP and AASB S2 require location-based Scope 2 disclosure. CDP specifically asks for both methodologies side by side. AASB S2 requires emissions reporting consistent with GHG Protocol, which mandates dual reporting. NetNada generates framework-specific outputs with location-based figures.
