Derived carbon impact

Carbon here is a calculation, not a measurement: avoided electricity and fuel from the sample ledger multiplied by the factors listed below. Water records carry no carbon figure because no confirmed factor is available. Sample data, not customer savings.

Sep vs Aug · illustrative sample series, not a ledger record

Methodology

Avoided kWh × grid factor, plus avoided diesel × fuel factor, annualised from sample meter windows. Not a carbon inventory and not a Scope 1, 2 or 3 report.

Factors and rates behind these figures

Every AED and tCO₂e value in the sample ledger is a metered sample quantity multiplied by one of these values. Published references are cited. Sample assumptions are placeholders, not tariffs or official factors, and are replaced with the organisation's own values at commissioning.

  • Grid electricity emission factor (Dubai)

    0.4041kgCO₂e / kWh

    Published reference

    DEWA Sustainability Report 2020, as indexed by Climatiq (AR4). Reference value from a 2020 publication. Confirm against DEWA's latest published factor before any real inventory.

  • Diesel combustion emission factor

    2.66155kgCO₂e / litre

    Published reference

    UK Government GHG Conversion Factors 2024, 100% mineral diesel (taken from a secondary reproduction). Not a UAE-specific factor. Confirm against the official publication and a locally accepted factor before real use.

  • Water supply emission factor

    Not calculated

    Not available

    No confirmed published factor located. Carbon is not calculated for water records until a confirmed factor is supplied.

  • Electricity rate

    0.45AED / kWh

    Sample assumption

    Illustrative sample rate. Not a published tariff. Replace with the site's billed rate.

  • Water rate

    8AED / m³

    Sample assumption

    Illustrative sample rate. Not a published tariff. Replace with the site's billed rate.

  • Diesel price

    3AED / litre

    Sample assumption

    Illustrative sample price. Not a published price. Replace with the site's purchase price.

  • Generator idle fuel use

    17litres / hour

    Sample assumption

    Illustrative sample asset parameter. Not measured. Replace with the generator's logged or rated idle consumption.

  • Unoccupied overnight window

    8hours / night

    Sample assumption

    Illustrative sample operating assumption. Used only to size potential impact before measurement. Replace with the site's occupancy schedule.

Carbon credits

These figures are calculated reductions, not carbon credits. A credit exists only after independent verification and issuance by a registry.
