Carbonfeel is a collaborative initiative focused on providing methodological and technological solutions to the processes of calculation, verification, certification and labeling of the Carbon Footprint (CF). Any and all organizations from different sectors of activity, business associations, Public Administrations, certifying agencies, environmental consultancies, non-governmental organizations, foundations, universities, etc. that are committed to combating climate change and believe that responsible business is possible, are invited to participate. The project advances the creation of the first network of Carbon Footprint knowledge intended for the consolidation of products and/or services databases, by using primary data. That is what was called Green Coin: "every product has its own environmental price, a price not derived from a database more or less reliable". The setting-up of a feedback system which organizes stores and shares these raw data is pioneering and innovative. Also, massive eco-labeling is possible due to a mixed organization-andproduct approach to the CF calculation (MC3 methodology), with no need for the active participation of all actors in the value chain. Finally, a number of complementary actions within the project, such as its feedback, assemblage, proposal of Recommended Load Allowances and implementation of a new metadata management system, are compiled and explained, showing why Carbon feel is already becoming an outstanding eco-project.
