The Carbon Accounting only requires information that is readily available for most companies.
To calculate Scope 1 emissions, you need information regarding the use of fuels for an entire fiscal year. Inputs may be entered in energy or mass units, for example tonnes of coking coal or kWh of natural gas.
To calculate Scope 2 emissions, you need information about electricity, heat and steam consumption per country per year.
To calculate Scope 3 upstream emissions, you need the revenue and spend volume of your company. You can choose to calculate the emissions using:
proxy statistical data for your industry or
the distribution of your spend volume into different categories such as machinery and equipment, chemicals, or business services, to name a few. To retrieve the distribution of spend volume, please refer to your procurement / ERP system.
To enhance the accuracy of your Scope 3 results, we recommend inputting supplier data that indicates the countries from which your purchased goods and services originate. This information would also be required if you choose to invite those suppliers.
