The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison.
Carbon Literacy is the knowledge and capacity required to create a positive shift in how humankind lives, works and behaves in response to climate change.. The Carbon Literacy Project defines Carbon Literacy as "an awareness of the carbon costs and impacts of everyday activities and the ability and motivation to reduce emissions, on an individual, community and organisational basis."
An Environmental Product Declaration (EPD) is a Type III environmental declaration that quantifies environmental information about the life cycle of a product. This can enable comparisons between products fulfilling the same function. [1] The methodology to produce an EPD is based on product life cycle assessment (LCA), [2] following the ISO ...
Individual action on climate change is about personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles. Such personal choices are related to the way people travel, their diet, shopping habits, consumption of goods and services, number of children they have and so on. Individuals can also get active in ...
carbon footprint – a measure of the carbon emissions that are emitted over the full life cycle of a product or service and usually expressed as grams of CO 2-e. carbon labelling – use of product labels that display greenhouse emissions associated with goods (www.carbontrustcertification.com for product carbon footprint methodology).
Some authors say that carbon neutrality strategies focus only on carbon dioxide, but net zero includes all greenhouse gases. [28] [29] However some publications, such as the national strategy of France, use the term "carbon neutral" to mean net reductions of all greenhouse gases. [3] The United States has pledged to achieve "net zero" emissions ...
The carbon footprint is a component of the total ecological footprint. Often, when only the carbon footprint is reported, it is expressed in weight of CO 2 (or CO2e representing GHG warming potential (GGWP)), but it can also be expressed in land areas like ecological footprints. Both can be applied to products, people, or whole societies.
