Step-by-step guide for carbon accounting with supplier+s

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 emissions, you need the revenue and spend volume of your company. You can choose to calculate the emissions using

  • (1) proxy statistical data for your industry or

  • (2) 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.

You can complete your Scope 1 carbon accounting in two simple steps: 

• Step 1 : Enter your direct emissions by selecting an activity from the list. You can switch between fossil fuels, bio energy and direct emissions in the top.

• Step 2 : After selecting the activity, please enter the amount/consumption in the physical unit of the activity and add it. 

To add another input, click on the 'Add new input' button in the top right corner. You can remove activities by clicking the trash button on the right side of the corresponding row.

Congratulations, you have completed step 1/3. Once you have completed this page, click 'Continue' to proceed with Scope 2 emissions. 

You can complete your Scope 2 carbon accounting in three simple steps:

• Step 1 : Select an indirect emission from purchased electricity, heat, steam and cooling by selecting an activity from the list. Please note you can switch between electricity or heat and steam in the top of the page.

• Step 2: After selecting an activity, enter the amount/ consumption in the physical unit of the activity. 

• Step 3 : After entering the amount, input the country where the energy is consumed and add the activity. 

To add another input click on the 'Add activity' button in the top right corner. You can remove activities by clicking the trash button on the right side of the corresponding row.

Congratulations, you have completed step 2/3. Once you have completed this page, click 'Continue' to proceed with Scope 3 emissions. 

You can complete your Scope 3 upstream carbon accounting in three simple steps:

Step 1: Please enter your company's total revenue in thousands of USD. This field is required for your carbon accounting. 

In addition, we recommend to enter the purchasing volume as share of revenue (%). This is an optional input. If left blank, your industry's average is automatically applied (based on your inputs in the company profile). However, for more accurate results, we recommend you include your company's specific spend as share of revenue.

Step 2: After entering your spend data, please allocate your purchasing volume. You can use the pre-fill with industry data button on the right (and then add or edit information) or manually complete this section for more accurate results. To add products or services, click the 'Add new product/service' button at the top of the page. Select a proposed product or service, assign a share of the purchasing volume, and add it.

You can remove activities by clicking the trash button on the right side of the corresponding row.

Step 3: You can manage your suppliers for each product or service for more accurate results and insights into your emissions hotspots. Click 'Assign supplier' and identify the suppliers that account for the majority of your spend for the product or service you've selected. To add a supplier, click 'Add new supplier' below the list. You can add a supplier you have already invited to the platform or add a new supplier by entering supplier-specific information (ID, name, country/region). Before closing, enter the percentage of spend for the product/service covered by this supplier.

After closing, you'll see a bar showing the share of assigned suppliers in the row you just edited.

Finally, calculate results to complete the process and see your organization's carbon footprint. Congratulations, you have completed step 3/3.

On the results page, you can explore emissions data across scopes (following GHG Protocol), suppliers, and your products/ services.

Additionally, you can engage the most relevant suppliers by inviting them to the platform for a deeper understanding of your supply chain. Please note that this is - beyond the free trial we may offer - subject to a commercial contract between you and ctrl+s GmbH, the operator of the supplier+s platform. For details, please see the Supply Chain Management section of the FAQ or reach out to sales@supplier-s.io.

To share some insights with your clients, you can copy aggregated results to the organization overview in the self-assessment.

Please note: supplier data is based on statistical values unless you invite your own suppliers to the supplier+s platform, which allows for more accurate results.
