Estas emisiones son vistas como externalidades negativas asociadas a la actividad productiva. El estudio comprende el cálculo de emisiones de gases contaminantes por rama, la estimación del costo, en cantidad y en valor, de la emisión de estos gases y la identificación de sectores estratégicos en la estructura actual de la economía. La conclusión es que las ramas del sector energético, y las que están muy vinculadas a él, son las que más contaminan y resultan importantes por su efecto en las demás. Estas ramas requieren supervisión para incrementar su eficiencia y reducir las emisiones de gases contaminantes, en tanto se desarrollan y adoptan tecnologías limpias para producir energía.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This is an assessment of the impact of greenhouse gas emissions on prices and quantities of production of the various industries that make up the 2003 input-output matrix of the Mexican economy. These emissions are seen as negative externalities associated to each industry's productive activity. The study includes the calculation of gas emissions by industry, the estimation of the relative costs of these gas emissions and the identification of "key sectors". The essential conclusion is that the key sectors of the Mexican economy are those of energy power production and others closely related to it; all these sectors are also the most polluting ones. In order to reduce gas emissions, it is required to strongly supervise their activities and find ways to produce a technology change so as to make them more efficient, meanwhile new clean technologies are set in operation to develop products substitutes.]]></p></abstract>
