Introduction

This report covers the sector_name, which covers SI.

Results show the total Scope 1, 2 and 3 emissions of the sector over the time period 2017 to 2019, how emissions intensities have changed over this time period, and what has caused changes in Scope 3 emissions. The sector’s supply chain emissions are broken down by the products in which emissions are embodied. For each of these products the source of emissions can be shown.

Greenhouse gas emissions are shown in terms of tonnes of carbon dioxide equivalent (CO2e). Further details on the methodology can be seen in the methodology document.

Total Carbon footprint by scope

Scope 1 emissions are the direct emissions of a sector. These are a result of on-site fuel combustion, process emissions and vehicles owned by companies in the sector. Scope 2 emissions are the emissions associated with electricity use of the sector, where the electricity is generated offsite.

Scope 3 emissions are associated with upstream purchasing: production and processing of raw materials, transportation, travel, and outsourced services, i.e. embodied emissions in the purchases of the sector. Scope 3 emissions sometimes also include downstream emissions (distribution of products sold, retail, use and disposal). These downstream emissions and employee commuting are not included here.

emissions Intensity by scope

The emissions intensity of the sector is shown in terms of emissions per unit of total monetary output of the sector (tCO2e per £ of output). This is indexed to 2017, inflation is accounted for so that the effect of real changes in output are shown. The change in emissions intensity is shown separately for scope 1, 2, 3 and total emissions.

Why have scope 3 emissions changed  over time?

The total change in scope 3 emissions is split into the effects of changes in:

Total purchasing: is the sector purchasing more or less? (Note corrections are made for inflation here).
Make up of purchasing: is the sector purchasing higher impact or lower impact products?
Supply chain impact factors: are the supply chains of products purchased getting more or less emissions intensive?

These three effects sum to the total change in scope 3 emissions.

What purchased products contribute to supply chain emissions?

The supply chain (scope 3) emissions are broken down by the different products the sector purchases, both in the UK and the Rest of the World (RoW). Any product group that contributed <1% towards the sector’s Scope 3 emissions is grouped in the ‘Others’ category. The chart relates to 2019.

For any of the important products (i.e. those not in the ‘Others’ category) you can select and see where these emissions actually occurred – the emissions that are ultimately embodied in a product can occur in a range of industries in both the UK and Rest of the World.

The use of some of these products (for example Gas or Electricity) may also lead to scope 1 and 2 emissions. What is included in this chart is only the scope 3 (upstream) impacts of these products.

For some sectors you may notice that a large contributor to scope 3 emissions are the products of the sector. For an explanation of this see the accompanying methodology.

Where do the emissions embodied in selected_product occur?
The source of emissions embodied in selected_product are shown. This shows in which sectors the emissions actually occur (i.e. they would be scope 1 emissions in this sector). Any sector that contributed <1% towards the total embodied emissions of the product is grouped in the ‘Others’ category.
