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 ...
Dopplr was a free social networking service, launched in 2007, [1] that allowed users to create itineraries of their travel plans and spot correlations with their contacts' travel plans in order to arrange meetings at any point on their journey. Additional features included allowing the user to calculate the carbon footprint their journeys have ...
Cycling has a low carbon-emission and low environmental footprint. A European study of thousands of urban dwellers found that daily mobility-related CO 2 emissions were 3.2 kg (7.1 lb) of CO 2 per person, with car travel contributing 70% and cycling 1% (including the entire lifecycle of vehicles and fuels).
For example, consumers can significantly reduce the carbon footprint of the last mile by walking, bicycling, or taking public transport. Another impact is that goods being transported by large ships very long distances can have lower associated carbon emissions or energy use than the same goods traveling by truck a much shorter distance.

Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
The Mayday Journey is an online resource that combines a carbon calculator with guidance designed to help companies develop a carbon strategy. The Journey is divided into four areas: reducing cost, engaging employees, suppliers and customers, building resilience through biodiversity and adaptation and developing a vision, termed transform.

The algorithms of ecological footprint accounts have been used in combination with the emergy methodology (S. Zhao, Z. Li and W. Li 2005), and a sustainability index has been derived from the latter. They have also been combined with a measure of quality of life , for instance through the " Happy Planet Index " (HPI) calculated for 178 nations ...
