10 Questions
- What is a carbon footprint and what does it measure?
A carbon footprint is an indicator that measures the total amount of greenhouse gases emitted from an activity, product, company, or country.
- How are carbon footprints usually reported?
Carbon footprints are usually reported in tons of emissions (CO2-equivalent) per unit of comparison, such as per year, person, kg protein, km travelled, and alike.
- What does the carbon footprint of a product include?
The carbon footprint of a product includes the emissions for the entire life cycle from production along the supply chain to its final consumption and disposal.
- How is the carbon footprint of an organization calculated?
The carbon footprint of an organization includes both the direct and indirect emissions caused by the organization. These are categorized as Scope 1, 2, and 3 emissions according to the Greenhouse Gas Protocol.
- What methodologies and tools can be used to calculate carbon footprints?
Several methodologies and online tools exist for calculating carbon footprints, depending on the focus of measurement. These tools can be used for calculating the carbon footprint of a country, organization, product, or individual person.
What is the purpose of calculating carbon footprints?
The purpose of calculating carbon footprints is to compare the total amount of greenhouse gases emitted from an activity, product, company, or country.
How is the carbon footprint of a product determined?
The carbon footprint of a product includes the emissions for the entire life cycle from production along the supply chain to its final consumption and disposal.
What is Scope 1, 2, and 3 in the Greenhouse Gas Protocol?
Scope 1, 2, and 3 refer to the direct and indirect emissions caused by an organization. Scope 1 includes direct emissions, Scope 2 includes indirect emissions from purchased electricity, and Scope 3 includes other indirect emissions.
What factors can be used as units of comparison for carbon footprints?
Carbon footprints can be reported per year, per person, per kilogram of protein, per kilometer traveled, and similar units.
What are some methodologies and tools used to calculate carbon footprints?
There are several methodologies and online tools available depending on the focus, such as calculating carbon footprints for a country, organization, product, or individual person.
Study Notes
Carbon Footprint
- A carbon footprint is a measure of the amount of greenhouse gases, particularly carbon dioxide, that are released into the atmosphere as a result of human activities.
Reporting Carbon Footprints
- Carbon footprints are usually reported in terms of tons of carbon dioxide equivalent (tCO2e) or tons of carbon equivalent (tC).
Product Carbon Footprint
- The carbon footprint of a product includes all the emissions generated during its entire lifecycle, from raw material extraction and processing, to manufacturing, transportation, usage, and disposal.
Organizational Carbon Footprint
- The carbon footprint of an organization is calculated by assessing the emissions generated by its operations, including energy consumption, transportation, and supply chain.
Calculating Carbon Footprints
- Methodologies and tools used to calculate carbon footprints include Life Cycle Assessment (LCA), Greenhouse Gas Protocol, and carbon footprinting software such as Carbon Trust and GHGProtoco.
Purpose of Carbon Footprint Calculation
- The purpose of calculating carbon footprints is to identify areas for reduction and mitigation, and to develop strategies for reducing greenhouse gas emissions.
Determining Product Carbon Footprint
- The carbon footprint of a product is determined by assessing the emissions generated during its entire lifecycle, from raw material extraction and processing, to manufacturing, transportation, usage, and disposal.
Greenhouse Gas Protocol
- The Greenhouse Gas Protocol is an internationally recognized standard for calculating and reporting greenhouse gas emissions, and it categorizes emissions into three scopes: Scope 1 (direct emissions), Scope 2 (indirect emissions from energy consumption), and Scope 3 (indirect emissions from supply chain and product use).
Units of Comparison
- Carbon footprints can be compared using units such as tons of CO2e, kilograms of CO2e, or carbon intensity (emissions per unit of revenue or product).
