Environment and Climate Change Canada (ECCC) — Emission Factors and Reference Values

Canada · 29 factors

DocumentEmission Factors and Reference Values, Version 4.0

PublishedPublished 9 September 2026 · aligned with the National Inventory Report 1990–2024

Grid intensities are Table 5.3, 2026 compliance year, published per province and territory. Fuel factors are the CO₂ value with CH₄ and N₂O added at IPCC AR5 GWP₁₀₀ (28 and 265). Natural gas is by province: CO₂ from Table 1.3 (2026, marketable gas) plus CH₄ and N₂O from Table 2.3 (residential, commercial and institutional), 10.3 g CO₂e/m³. The calculator takes the province from the electricity grid in your data and asks when that does not settle it; until then the highest provincial value is used. Gas entered in kWh or GJ is converted at ECCC’s higher heating value, 38.39 MJ/m³ (Table 8). Until September 2026 one national 1,940 g/m³ was used, which is not a figure the table contains. Diesel is Table 4.3: 2,681 g CO₂ + 0.078 g CH₄ + 0.022 g N₂O per litre = 2,689 g CO₂e/L.

United States Environmental Protection Agency (EPA) — eGRID electricity factors

United States · 28 factors

DocumentGHG Emission Factors Hub (2025) and eGRID2022

PublishedHub published 15 January 2025 · eGRID2022 released 30 January 2024

Fuel factors are converted from the Hub’s per-mmBtu, per-US-gallon and per-short-ton values, with CH₄ and N₂O added at AR5 GWP₁₀₀. Electricity uses eGRID’s total output CO₂e rate for each subregion (lb/MWh × 0.453592), from the edition named above and in each row. All 27 eGRID subregions are loaded (15 were added in factor database release R10). Which subregion a US state is in follows EPA’s Power Profiler ZIP Code Tool v14.3: where one subregion holds 90% or more of a state’s ZIP codes, the state name is enough; otherwise the calculator asks which part of the state, and a city or subregion code on the same line (“Houston”, “RFCE”) settles it. New York has three subregions that differ 4.4-fold (Upstate 0.125, New York City 0.402, Long Island 0.549), so a line that only says “New York” is asked, not assumed. History: until September 2026 the grid values were labelled eGRID2022 but did not match it (CAMX 0.195 against eGRID2022’s 0.2265; they appear to have been eGRID2023 values, rounded). In September 2026 they were set to the eGRID2022 table they were labelled with; in factor database release R4 (October 2026) they moved to eGRID2023 revision 2, EPA’s current edition, with that label.

Central Electricity Authority (CEA), India — CO₂ Baseline Database

DocumentCO₂ Baseline Database for the Indian Power Sector, Version 22.0

PublishedPublished August 2026 · financial year 2025–26

The grid figure used is the weighted average emission factor (0.675 tCO₂/MWh), which is the correct basis for corporate Scope 2 reporting. It is not the combined margin (0.705), which exists for offset and CDM baselines. Indian fuel factors use IPCC 2006 Tier 1 defaults, the basis of India’s own national inventory, except coal. Natural gas is also on a gross basis (0.1836 kg CO₂e/kWh, m³ at 8,800 kcal/m³); see the table under DESNZ/DEFRA. Coal is priced per GJ of gross calorific value with CEA’s own factors (Appendix B of the same User Guide): India’s national-communication value for domestic coal, 95.8 kg CO₂/GJ on a net basis, is 92.5 on a gross basis and 90.6 after CEA’s 98% oxidation factor. The calculator asks for the coal’s GCV (kcal/kg or GJ/t, from the invoice or test certificate) and converts tonnes to GJ at 0.0041868 GJ/t per kcal/kg. These are CO₂ only, as CEA publishes them.

Grid factors are Table 1, location-based Scope 2, by state or grid, for financial years ending in June. They are not Table 3, which exists for abatement-method calculations, and the Scope 3 transmission-loss column is not added. Fuel factors multiply the published energy content (GJ/kL or GJ/t, gross calorific value) by the combined-gas factor (kg CO₂e/GJ) from Tables 4, 5 and 8; the arithmetic is printed in each row.

Document2023 Electricity CO₂ Emission Factors, MEE Announcement 2025 No. 47

PublishedPublished 31 December 2025 · data year 2023

The national figure (0.5306) and the provincial figures are the average factors the MEE designates for location-based accounting. They are CO₂ only. Three other MEE figures are deliberately not used for Scope 2: the factor excluding market-traded non-fossil power (0.6096, for market-based accounting), the fossil-only factor (0.8273), and the separate electricity carbon-footprint factor (0.6205), which is a life-cycle value for product footprints. Hong Kong, Macau and Taiwan are not covered and are never mapped to these values. China has no per-litre fuel factor loaded yet: Scope 1 liquid and gas fuels under the China setting use IPCC 2006 Tier 1 defaults and say so on every row. Coal follows the enterprise accounting method (NDRC 2015 工业其他行业企业温室气体排放核算方法与报告指南, Appendix 2 Table 2.1, the method MEE applies outside the power sector): tonnes × low calorific value × carbon content × oxidation rate × 44/12. The calculator asks which kind of coal and uses the guideline defaults below unless you enter your lab’s results; a lab carbon content becomes a self-declared factor. The power sector has its own guideline and is not covered here.

Published11 June 2026 · version 1.2 updated 10 July 2026

Used wherever a jurisdiction publishes no value of its own, and as the default international set. This is the fallback you will see labelled “no value published — DESNZ used” in the tool. Until CR 16 (September 2026) this set was the 2024 edition; every international value below is now the 2026 figure, and the change for each is in the project log. Natural gas entered in m³ is converted with each authority’s own energy content before its per-kWh factor is applied: Canada 10.664 kWh/m³ (ECCC Table 8 HHV 38.39 MJ/m³), US 10.619 (EPA Table C-1, 1,026 Btu/scf, which also sets scf, ccf and Mcf), Australia 10.917 (NGA 39.3 MJ/m³), China 10.814 (MEE 389.31 GJ/10⁴ Nm³), international 11.115 (DESNZ 2026’s own figures: 2.02633 kg per m³ ÷ 0.18231 per kWh, so a bill in m³ gets the published per-m³ value). India 10.234 (CEA’s default gas GCV, 8,800 kcal/m³, User Guide v22.0 Appendix B — a power-station default, so a PNG bill’s own GCV is better). India’s gas factor is put on the same gross basis: IPCC’s 0.202 kg/kWh net ÷ 1.10, CEA’s GCV/NCV ratio for gas, = 0.1836, because Indian gas is billed and reported on gross calorific value. The hybrid and electric commuting rows use the DESNZ 2026 average-car figures internationally (the electric figure includes UK-grid charging); in the other jurisdictions they remain derived: an assumed 5.0 L/100 km for the hybrid, and an assumed 0.20 kWh/km at the plug for the electric car, multiplied by that jurisdiction’s own gasoline factor or national grid average. The owned bus/coach row is derived everywhere — DESNZ publishes no per-vehicle-km bus factor. For an electric car in Canada the charging province matters far more than the national figure shown.

Intergovernmental Panel on Climate Change (IPCC) — 2006 Guidelines and AR5 GWPs

Global · 8 factors

Document2006 Guidelines for National GHG Inventories · AR5 GWP₁₀₀

PublishedGuidelines 2006 · GWP values from the Fifth Assessment Report, 2014

Refrigerant factors are AR5 100-year global warming potentials (the same values DESNZ 2026 lists; its full list of 166 gases and blends is in the library below), the basis ECCC, US EPA (from reporting year 2024), DESNZ and NGER all require. Blends are the mass-weighted sum of their components. Until September 2026 the R-410A and R-134a rows carried the AR4 values 2,088 and 1,430. Tier 1 default fuel factors are used for India and China except for coal, and anywhere without a national set. The coal-by-energy rows below are CO₂ from Volume 2 Table 1.4 plus CH₄ 10 and N₂O 1.5 kg/TJ from Table 2.3 (manufacturing industries) at AR5 GWPs, net calorific basis; they apply wherever no national per-GJ coal factor is loaded.

These factors are used only for the market-based Scope 2 figure, never for the location-based total. They price the electricity that no certificate, contract or supplier rate the preparer holds has covered (GHG Protocol Scope 2 Guidance, 2015). In Australia the NGA Factors 2026 method zero-rates the Renewable Power Percentage (and the ACT’s own percentage) first. The United Kingdom and China figures are published as CO₂ only and are used as published. Green-e labels its rates CO₂, but they are built on the same eGRID2023 CO₂e rates as the location factors above. Canada, India, the US national average and other countries publish no residual mix: there, the location factor stands in and every such line says so. The Green-e and AIB figures are quoted value by value with their citation; their full tables are not reproduced. NGA 2026 Example 2 uses an RPP of 0.1667 labelled “2024 and 2025”; that is the 2026 figure, so this database uses NGA’s own definition (17.91% and 16.67% averaged). Green-e · AIB · CER

These factors price the upstream emissions of the fuel and energy already counted in Scope 1 and 2: extracting, refining and transporting fuels (well-to-tank), and electricity lost in the grid (transmission and distribution, T&D). They go only into Scope 3 Category 3 and never change Scope 1 or 2 (GHG Protocol Scope 3 Standard, 2011, chapter 5). For fuels the calculator uses the DESNZ well-to-tank factor of the same fuel unless the preparer picks a factor from their own licensed library; outside the United Kingdom DESNZ is used as an approximation, and every such line says so. Australia uses its own NGA scope 3 factors. In the United States, T&D losses = consumption × GGL ÷ (1 − GGL) × the location factor. Canadian (ECCC) factors are consumption intensities that already include grid losses, so no T&D line is added there. No upstream factor is published for grid electricity in India, China or other countries; those lines are listed as not covered rather than estimated. Refrigerants and process emissions have no Category 3 component. DESNZ · NGA · eGRID

PublishedVarious, 2018–2026 — see each row

Materials and food factors are cradle-to-gate life-cycle values. They carry wider uncertainty than combustion factors and are not tied to any single jurisdiction. Until CR 16 sixteen of these rows were labelled “ecoinvent”. That label could not be traced to a dataset, and ecoinvent’s licence does not allow its values in a public calculator, so each was replaced with an open, published figure or — where none was found — kept and marked Unverified. Factor database release R2 withdrew the unverified hops, cleaning-product and cooking-oil rows, replaced yeast with COFALEC’s published figures for compressed and dry yeast, and kept purchased services, marked Unverified, until its EXIOBASE figure was traced. It never was: release R5 (October 2026) withdrew it and replaced it with the US EPA spend-based factors by category, in their own section below. Two rows are derived from an assumed mass (a 200 g bottle, a 25 kg pallet), and say so.

DocumentSupply Chain Greenhouse Gas Emission Factors v1.3 by NAICS-6 (SupplyChainGHGEmissionFactors_v1.3.0_NAICS_CO2e_USD2022.csv), v1.3.0 — 2022 GHG data, 2022 US dollars at purchaser price, IPCC AR5 GWP100

Published5 Jul 2024

When a purchase is known only by what it cost, the calculator prices the money with the factor for its category: kg CO₂e per dollar spent, covering the supply chain of what was bought (Scope 3, categories 1 and 2). The figures are EPA’s “with margins” values per 2022 US dollar at purchaser price, IPCC AR5. Each is shown here per euro, the base of this tool’s currency table, at the ECB’s 2025 average (1 USD = 0.88496 EUR), so a dollar entered in USD is priced exactly at EPA’s figure. Two limits are stated on every row: the prices are 2022’s, not adjusted for inflation since, so spend from later years is somewhat overstated; and the model is of the US economy, an approximation elsewhere. A line that names its category (“legal fees”, “frais bancaires”, “AWS hosting”) is priced in it; a line that does not (“miscellaneous supplies”, “sous-traitance”) is asked — the categories differ about thirtyfold, so none is assumed. A quantity (litres, kWh, kilograms, nights) is always better than spend. Until release R5 every such line was priced at one services average, 0.30 kg/EUR attributed to EXIOBASE, which could not be traced to any EXIOBASE table.

DocumentUK Government GHG Conversion Factors for Company Reporting 2026, version 1.2 (flat file)

Published11 June 2026 · version 1.2 updated 10 July 2026

Every activity DESNZ publishes a figure for, except well-to-tank, managed assets and the UK electricity rows already above. Each factor is the published per-unit value; fuels also accept every other unit DESNZ publishes (tonnes, kWh gross and net) and plain unit conversions of them (US and UK gallons, m³, MWh, GJ, therms). The calculator finds these from what you write — “red diesel”, “R-407C”, “medium diesel car”, “cardboard sent for recycling”, “hotel nights in Toronto” — and always shows the DESNZ name. Where another authority (ECCC, EPA, CEA, DCCEEW, MEE) governs your report and publishes a generic figure but nothing for the specific type, the tool uses that authority’s generic figure and says so on the row — but only when the generic is built on the same fuel and unit: a petrol or unknown-fuel car or van takes the local generic (it is derived from gasoline), while diesel, hybrid, plug-in hybrid, battery-electric, CNG and LPG types keep the DESNZ figure (zero in Scope 1 for battery-electric: its charging is Scope 2). Bioenergy figures are CH₄ and N₂O only: DESNZ reports the biogenic CO₂ separately, outside the scopes. Six newer refrigerant blends DESNZ does not list (R-448A, R-449A, R-452A, R-454B, R-454C, R-513A) are derived from their ASHRAE 34 composition and the AR5 values, and marked so. Food items are Poore & Nemecek (2018) global means, as published by Our World in Data.

GHG Protocol — zero-emission travel

DocumentTechnical Guidance for Calculating Scope 3 Emissions, v1.0 (Category 7, employee commuting)

Published2013

Walking and cycling burn no fuel, so their direct emission factor is zero by definition. The row exists so the distance is recorded and the commuting modal split can be reported, not because anything is added to the total.

How a factor gets chosen. The calculator reads the grid region named in your data and selects the matching national set — ECCC for Canada, EPA for the United States, CEA and IPCC for India, DCCEEW for Australia, MEE (grid) and IPCC (fuels) for China, DEFRA otherwise. Where that jurisdiction publishes nothing for an activity, the DEFRA value is used and the row says so rather than substituting silently. You can override the jurisdiction at any time, and any factor you enter yourself is labelled self-declared everywhere it appears.
