The sustainability report states: 'Our annual ___ 2 emissions are 450 tCO2e from data centre electricity.'
Scope 2 emissions under the GHG Protocol are indirect emissions from the generation of purchased electricity, steam, heat, or cooling consumed by an organisation. For IT, this primarily covers data centre power consumption. tCO2e means tonnes of CO2 equivalent.

The team uses a cloud ___ calculator to estimate the emissions from their AWS workload.
A cloud carbon calculator (e.g., AWS Customer Carbon Footprint Tool, Google Carbon Footprint, Azure Emissions Impact Dashboard) estimates CO2e emissions from cloud resource consumption, using energy use data and regional electricity grid carbon intensity.

The model ___ emissions from electricity consumption by multiplying kWh by the grid emission factor.
The standard methodology for estimating IT emissions multiplies electricity consumption (kWh) by the emission factor of the grid (gCO2e/kWh), which varies by region and time of day. This gives the estimated carbon impact of running workloads.

The audit team evaluates the carbon ___ methodology used to calculate the annual report figures.
Carbon accounting methodology defines how emissions are identified, measured, allocated, and reported. For IT this includes decisions like whether to use market-based or location-based Scope 2 accounting, and how to allocate shared infrastructure emissions.

The sustainability lead sets a target to reduce Scope 1, 2, and 3 emissions by 45% — measured in ___.
tCO2e (tonnes of CO2 equivalent) is the standard unit for carbon footprint reporting. It converts all greenhouse gases (CO2, CH4, N2O, etc.) into the equivalent amount of CO2 that would produce the same warming effect.
