Emissions compensation (Carbon Offsetting)
Introduction
A carbon offset is a reduction in emissions of carbon dioxide or greenhouse gases made to offset an emission made elsewhere.[1][2][3][4].
Through this mechanism, governments, companies or individuals provide support to initiatives that reduce CO2 in the atmosphere - such as the planting of trees or the generation of renewable energy - with the aim of offsetting the emissions produced by their economic activities.
Carbon offsets are measured in metric tons of carbon dioxide equivalent (CO2e) and can represent six primary categories of greenhouse gases: carbon dioxide (CO
), methane (CH
), nitrogen oxide (I) "Nitrogen oxide (I)") (N
O), fluorocarbons (PFC), hydrofluorocarbons (HFC) and sulfur hexafluoride (SF
).[5][6] A carbon offset represents the reduction of one metric ton of carbon dioxide or its equivalent in other greenhouse gases.
Carbon offsetting has gained some traction and momentum, primarily among consumers in Western countries, who have become aware of and concerned about the potentially negative environmental effects of energy-intensive lifestyles and economies.
Markets

Hay dos mercados para las compensaciones de carbono: el obligatorio y el voluntario.
Mandatory market
In the largest, obligated entities, companies, governments or other entities purchase carbon offsets to comply with limits on the total amount of carbon dioxide they are allowed to emit. This market exists to achieve compliance with the obligations of Annex 1 of the Kyoto Protocol, and of entities affected by the European Union Emissions Trading Regime. In 2006, about $5.5 billion of carbon offsets were purchased in the compliance market, representing about 1.6 billion metric tons of CO2e reductions.[7].
The Kyoto Protocol has established offsets as a way for governments and companies to earn carbon credits, which can then be exchanged in the market.[8] The protocol established the Clean Development Mechanism (CDM), which validates and measures projects to ensure that they produce genuine benefits and are truly "additional" activities that would not otherwise have been undertaken. Organizations that cannot meet their emissions quotas can offset their emissions by purchasing CDM-approved emissions reduction certificates. Emissions from some types of fuel, such as diesel, have forced one of the United Kingdom's fuel suppliers to create a fuel called Carbon Offset Red Diesel.
