A GHG inventory you can explain, line by line
ESGTrack calculates Scope 1, 2 and 3 from the activity data your teams approve, with the factor, its source and the month it applied kept beside every result — then turns the inventory into targets and a plan to reduce it.

The inventory, built from approved activity data
ESGTrack follows the GHG Protocol Corporate Standard and ISO 14064-1 on your organisational boundary. Scope 1 comes from fuel logs reconciled against stock checks and meters — with lab calorific values where you have them — and from a refrigerant log; Scope 2 from electricity, read from bills or meters, with renewable energy, certificates and green tariffs recorded beside it.
- Emission factors chosen by date: the factor in force for each month, never one typed by hand into a total
- Your own site and company factors take precedence over the library
- Unusual figures pointed out while you type; anomaly checks on every monthly series, ranked by the tonnes at stake
- A register of the reporting boundary and of restated figures
Two worked examples
| Activity | Factor (bundled library) | Emissions |
|---|---|---|
| 2,200 L of diesel in a generator | 2.685 kg CO₂e per litre — IPCC 2006 gas/diesel oil, default NCV, density 0.84 kg/L assumed, AR5 | 5.91 tCO₂e |
| 120,000 kWh from the grid in India, FY 2025-26 | 0.675 kg CO₂ per kWh — CEA CO2 Baseline Database v22, weighted average including renewables | 81.0 tCO₂ |
Emissions = activity × factor. The CEA factor is for CO₂ only. Which factor applies to your company is a decision for your inventory's methodology — ESGTrack records the one you use.
A factor library with its sources attached
The bundled library holds 10,380 factors, each with its publisher, edition, unit, gases and global warming potentials. Platform administrators keep it current; companies add their own.
| Publisher | What it covers |
|---|---|
| Central Electricity Authority, Government of India | CO2 Baseline Database v22: Indian grid emission factors by year (weighted averages and margins) and power-station data |
| US Environmental Protection Agency | GHG Emission Factors Hub (fuels, transport, refrigerants) and Supply Chain GHG Emission Factors v1.3 for spend-based Scope 3 |
| Intergovernmental Panel on Climate Change | 2006 Guidelines default factors for energy, and the 2019 Refinement for industrial processes, waste and agriculture |
| India GHG Program (WRI India, CII, TERI) | India-specific road transport factors for travel and commuting |
| Our World in Data (Ember, Energy Institute) | Carbon intensity of electricity by country, for sites outside India |
Scope 2 both ways, and Scope 3 by category
Location-based Scope 2 uses the grid's average; market-based reflects the electricity you contracted for. Scope 3 starts from spend — sorted into the GHG Protocol's 15 categories, with AI if you switch it on — and improves with activity data and supplier figures where they matter most.
- Business travel, employee commuting (with a commute survey) and freight from activity data
- Supplier-specific figures collected through a supplier link and network
- Each category shows its method, so improvements can be targeted
- Renewable energy certificates and green tariffs recorded for market-based Scope 2

From inventory to a plan
The decarbonisation planner starts from the approved inventory. Add initiatives from 15 lever templates or projects suggested from your own emission sources; ESGTrack shows the pathway to your target, the cost per tonne and payback of each initiative, a marginal abatement cost curve, what-if changes and scenarios. Targets and actions are then followed from your data.
- Climate risk site by site: groundwater stress, physical hazards and carbon-price scenarios
- Benchmarks across your sites and against peers' BRSR XBRL filings
- The same inventory feeds CBAM, India's CCTS and product carbon footprints

Questions about carbon accounting
Which emission factors does ESGTrack use?
Your own factors first — a site's factor before your company's — then a bundled library of 10,380 factors from public sources, including CEA's CO2 Baseline Database for Indian grid electricity, the US EPA's GHG Emission Factors Hub and supply-chain factors, and the IPCC's 2006 Guidelines and 2019 Refinement. Each entry uses the factor in force for its month, and the factor's source stays with the result.
Do you report Scope 2 location-based or market-based?
Both. Location-based uses the grid's average emissions; market-based reflects the electricity you chose to buy — renewable energy certificates, green tariffs or a power purchase agreement — as the GHG Protocol's Scope 2 Guidance asks companies with such instruments to do.
How is Scope 3 calculated?
From spend, sorted into the GHG Protocol's 15 categories and multiplied by spend-based factors; from activity data such as business travel, employee commuting and freight; and from figures your suppliers send. Each category shows the method behind it, so you can improve the estimate where it matters most.
Is the inventory ready for BRSR, CDP and the ISSB?
The same approved inventory feeds BRSR Principle 6 and BRSR Core, CDP's emissions questions and the ISSB and ESRS climate disclosures. The crosswalk shows where each framework asks for the same figure and where definitions differ.
