How to quantify and reduce your scope 3 emissions

Unlike Scope 1 and 2 emissions, Scope 3 emissions are far harder to control and track accurately, but they are key to reaching net zero. With Scope 1 and 2, an organisation will normally have the data required to convert direct purchases of gas and electricity into a value in tonnes of GHGs. Most organisations are unlikely to have the same insight when it comes to suppliers of other goods and services.

Life Cycle Assessment (LCA) can be used to quantify Scope 1-3 emissions by providing information on the environmental impacts of systems, services and products throughout the entire life cycle. It therefore enables you to accurately and efficiently plan and deliver a road map to reduce emissions in line with a net zero strategy.

Seyed Ebrahimi, Principal Consultant, Sustainability Strategy, discusses Life Cycle Assessment (LCA) as a means to enhance supply chain management and meet net zero targets.
Life Cycle Assessment

Life Cycle Assessment (LCA) can be used to provide information on the environmental impacts of processes, services and products throughout the entire life cycle. LCA, also known as Life Cycle Analysis and ‘cradle-to-grave’ analysis, refers to the assessment of environmental impacts of a product throughout its life cycle from its raw materials to disposal or recycling. The various stages considered in assessing the environmental impacts start from the extraction of raw materials and move toward material processing, manufacture, distribution, use, repair, maintenance, and disposal or recycling (ScienceDirect, 2022).

Benefits of an LCA:

To support clients with identifying cost/emission hotspots (baseline) for a particular product/service

Life Cycle Costing (LCC)

Life Cycle Costing maps the total cost of ownership of a product / service / system throughout its entire life span (cradle-to-grave costs). LCC is best used to evaluate the procurement of a new product/service and can provide informed decision making on how (and where) to reduce costs throughout the different stages of the product life cycle (raw material acquisition, manufacturing/processing, use-stage, maintenance and end of life).

Environmental Product Declarations (EPD)

An EPD is a standardised document used in both B2B and B2C communications. It transparently and scientifically describes the environmental impacts of your system/product/service. EPDs are validated by a third party and as such can be used to compare with EPDs for other products/services if the same product category rules are applied. The most common industry making use of EPDs is the construction sector, but increasingly it is becoming popular in other industries.
