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.

1

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.

2

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.

3

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.

4

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).

5

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.

ICC Sydney
Jessica Zickar, CSR Manager
"Having location-based Scope 2 calculated automatically with the correct NGA factors for NSW saved us hours of manual lookup and calculation. When the new NGA factors are published each year, NetNada updates automatically. Our CDP submission now has consistent location-based and market-based figures side by side."
Impact:
  • Eliminated manual NGA factor lookup and calculation errors
  • Reduced Scope 2 calculation time from 2 days to 15 minutes
  • Achieved consistent dual reporting across CDP and Climate Active
Logistics Company
Environmental Compliance Manager, Environmental Compliance Manager
"With depots in every state, our location-based Scope 2 varies hugely by site. NSW and QLD depots have 3x the electricity emissions of our Tasmanian facilities for the same consumption. NetNada made this visible immediately, so we prioritised energy efficiency investments where the grid factor — and therefore the abatement opportunity — was highest."
Impact:
  • Identified 40% variance in emissions intensity across state grids
  • Prioritised energy efficiency spend on highest-impact sites first
  • Reduced location-based Scope 2 by 22% through targeted efficiency upgrades

Frequently Asked Questions

Everything you need to know about Scope 2 Location-Based Calculator

What are NGA emission factors?
National Greenhouse Accounts (NGA) emission factors are published annually by the Australian Government (Department of Climate Change, Energy, the Environment and Water). They provide grid-average emission factors for each Australian electricity grid — the amount of CO2e produced per unit of electricity consumed. These are the authoritative factors for Australian emissions reporting under NGERS and most voluntary frameworks.
Why do grid factors differ between Australian states?
Each state's grid has a different mix of generation sources. NSW and QLD grids are coal-heavy with higher emission factors. SA has significant wind and gas, resulting in moderate factors. Victoria has brown coal but growing renewables. Tasmania is predominantly hydro with the lowest emission factor. These differences mean the same kWh of electricity causes different emissions depending on location.
Do I need location-based if I already have market-based?
Yes. GHG Protocol mandates dual reporting — both location-based and market-based. CDP, Climate Active, and AASB S2 all require location-based disclosure. Even if your market-based is lower due to renewable procurement, location-based provides the grid context that stakeholders need. It's also the correct metric for tracking energy efficiency improvements.
How often are NGA factors updated?
The Australian Government typically publishes updated NGA factors annually, usually in the second half of each year. NetNada updates its factor library as soon as new NGA tables are released. Historical factors are preserved for prior-year reporting, and you're notified when updates affect your calculations.
What about Scope 3 transmission and distribution losses?
Electricity transmitted through the grid incurs physical losses — typically 5-10% of generation. NGA publishes separate Scope 3 emission factors for these transmission and distribution losses. NetNada calculates both Scope 2 (consumption) and Scope 3 (T&D losses) automatically, giving you the complete picture of electricity-related emissions.
Can I use location-based for facilities outside Australia?
Yes. NetNada maintains grid emission factors for over 100 countries and sub-national regions, sourced from IEA, national registries, and authoritative local publications. The same location-based methodology applies: consumption multiplied by grid-average factor for the relevant region. Geographic coverage is continuously expanding.
How does location-based handle embedded networks?
Facilities on embedded networks (receiving electricity through an intermediary rather than directly from the grid) still use the grid emission factor for their region. The electricity ultimately comes from the same grid. NetNada allows you to flag embedded network sites and apply the correct regional grid factor regardless of the billing arrangement.
Is location-based calculation free?
Yes, location-based Scope 2 calculation is included in all NetNada plans including the free tier. Enter your electricity consumption data, select your grid regions, and receive location-based emissions instantly. Paid plans add features like automated data ingestion, multi-year historical tracking, and advanced reporting exports.
