Scope 3 Emissions
Mains water
Where can you find the information for this questions?
Mains water will be supplied by the local water company and used onsite for cleaning, sanitary, and some production activities such as steam generation, and cooling of manufacturing equipment.
The information to answer this question, in order of suitability, is as follows (1 being the most suitable):
Direct meter readings taken on site, or taken from supplier bill
Supplier bill based on estimated consumption
Estimated data (refer to the 'Guidance on estimating data' section)
The site should consult with plant or utility engineers to obtain direct meter readings.
The water bill will state if the bill is based on estimated consumption, the site can obtain the water bill from the finance team. If this is the case, the site should first try to obtain direct meter readings as the most suitable information to answer the question.
Units
The default unit for water consumption is cubic metres, m3. This is a measure of total water that has been supplied to the site.
Waste
Types of waste
The waste data will be reported by type of waste. It is good practice to separate waste on site by material before disposal.
The following categories are provided:
Construction waste: associated with building and renovation activities onsite and includes materials such as concrete, bricks, insulation etc.
Refuse: common types of waste such as household residual waste, organic: food and drink waste etc.
Electrical: this is legally referred to as waste electrical and electronic equipment (WEEE) and refers to any electronic waste disposed of by the site that must be disposed of separately such as fridges and freezers, batteries etc.
Metal: this refers to any waste that is metal material such as scrap metal, steel cans, etc.
Plastic: this refers to any waste that is plastic material such as PET, HDPE etc.
Paper: this refers to any waste that is paper material, including cardboard such as paper, cardboard, or mixed.
Other: this category includes books, glass, and clothing
Where can you find the information for this question?
The information to answer this question, in order of suitability, is as follows (1 being the most suitable):
Waste weight measurements taken on site, or taken from supplier bill
Supplier bill based on estimated generated waste
Estimated data (refer to the 'Guidance on estimating data' section)
The waste data will be available from the site’s waste disposal contractor. Many contractors will provide a report for clients detailing the types of waste and the disposal methods for the waste.
Alternatively, this information should be in the invoice sent for disposal of waste on a weekly, biweekly, or monthly basis.
The site’s finance team can provide a copy of the invoice.
Units
The types of waste onsite should be selected from their categories, and the consumption information should be entered for all waste disposed of in tonnes.
If more than one type of waste is disposed of, data should be entered for all those that apply.
Scope 3 emissions
Types of scope 3 emissions
Some organisations will be further along in their reporting journey and may have calculated scope 3 emissions themselves for a wider range of categories. This aspect of the questionnaire is designed to capture the information available in those circumstances.
Scope 3 emissions cover all value chain activities. In order to fully understand an organisation’s scope 3 emissions and identify activities with relatively high emissions, they are reported in 15 different categories:
Purchased goods and services
Capital goods
Fuel and energy related activities
Upstream transportation and distribution
Waste generated in operations
Global business travel
Employee commuting
Upstream leased assets
Downstream transportation and distribution
Processing of sold products
Use of sold products
End-of-life treatment of sold products
Downstream leased assets
Franchises
Investments
Where can you find the information for this question?
This information will be from calculations already performed by the site. Guidance for how to calculate each category is available from the GHG Protocol here.
The site’s environmental health and safety (EHS) team will be able to provide this information.
Please ensure the scope 3 carbon emissions data is for this site and not at entity level. Scope 3 carbon emissions should be entered in your JOSCAR questionnaire.
