What is a Carbon Footprint?

Carbon footprint is the total quantity of greenhouse gas emissions resulting from activities of individuals, organisations, events, or of production. Greenhouse gas emissions express themselves as molecules of carbon dioxide equivalent (CO2).

Fight against climate change that is caused by greenhouse gas emissions is the strategic priority of the European Community. The set strategies and adopted legislation encourage different states and regions to establish their own emission reduction strategies.

Why calculate your carbon footprint?

By calculating our carbon footprint, we can see what level of environmental performance we have achieved in terms of greenhouse gases and better understand where emissions are coming from, so that we can reduce them effectively.

Carbon footprinting is becoming a marketable tool and is increasingly being used by many organisations to provide the information they need to:

  • reduce and control emissions.
  • monitor their footprint and look for potential savings.
  • report accurately and meet the requirements of business partners, customers or investors.
  • enable their customers to choose a greener product or service.
  • obtain the necessary inputs for decision-making in purchasing, material selection and product development in production.
  • confirm their social responsibility and gain a competitive advantage.

The credibility and comparability of the data used in the calculations can only be ensured by following standards and guidelines. The choice of these depends on the type of calculation involved.

SIQ will:

  • calculate the carbon footprint at the level of the organisation.
  • calculate the carbon footprint at product level.
  • verify your carbon footprint calculation and methodology.

Calculation of the carbon footprint at an organisation level

ISO 14064-1 distinguishes three resource categories in the guidelines for calculating the carbon footprint (GHG protocol):

  • Scope 1: direct emissions (generated by activities or equipment the organisation owns or controls)
  • Scope 2: indirect emissions (all purchased energy consumed by equipment or activity).
  • Scope 3: refers to all other indirect broadcasts (transport of employees to and from work, business travel, different services) – it includes everything that is not owned by the organisation, yet affects it.

Calculation of the carbon footprint at product level

ISO 14067 and PAS 2050 define the scope of the calculation as the first step.

It is characterised by two different procedures:

  • B2C (Business to Consumer): the whole process is taken into consideration, which includes extraction of raw materials, processing, production, retail distribution, consumer use, disposal or recycling.
  • B2B (Business to Business): includes raw materials used in production and their processing, to the point at which a new organisation takes over the production, and executes the product’s packaging, storage and transport to the customer.

When calculating the carbon footprint, a methodological report is prepared with included suggestions of measures that could control and reduce carbon dioxide emissions.

Carbon footprint verification

Carbon footprint verification is performed according to the guidelines of ISO 14064-3. It includes:

  • review and verification of the methodological report for the calculation.
  • review of the determined emission sources.
  • an overview of the factors used to calculate the carbon footprint.
  • drafting of the verification report.
  • independent review, validation of the report and production of the verifier’s written opinion.
