| Summary/Abstract |
This paper analyzes trends in fuel economy (kilometers per liter) of new passenger vehicles in Mexico over a period of 20 years from 1988 to 2008. Results show that in this period, fuel economy of the new passenger vehicle fleet, including multipurpose vehicles (a category similar to sport utility vehicles, SUVs), increased by only 6.3%. A simple Laspeyres index analysis was developed to evaluate both the impact of changes in vehicle sales structure by category and the changes in fuel economy. Results show that increased sales of heavier, multipurpose vehicles in place of subcompact and compact vehicles, impacted negatively on the fleet average fuel economy. If the structure of sales had continued in the same proportions across all categories as in 1988, fuel economy would have increased by 11.0%, instead of the actual 6.3%. This result coincides with trends in other countries. The paper also presents different scenarios of passenger car fuel economy for the year 2020, and its implications for gasoline consumption and CO2 emissions. The results may influence the new passenger vehicle fuel economy standard that is currently under discussion in Mexico.

| Summary/Abstract |
The authors analyze the Mexican energy policy taking as reference the methodological framework for sustainable energy development proposed by the Economic Commission for Latin America and the Caribbean. This methodology takes eight related indicators to the social, environmental and economic dimensions in order to calculate a general sustainability indicator for the energy sector. In this methodology, the weight of each dimension is different; namely, the social and environmental issues have less relevance than the economic issues. The authors use this methodology because government institutions as the Department of Energy and the Department of Environment and Natural Resources have used some indicators from such a methodology to propose plans, programs, projects and bills. Authors know of the existence of other methodologies about sustainability. Nonetheless, opting for the Economic Commission for Latin America and the Caribbean's methodology is convenient because this organization is a respectable authority for civil servants from the Mexican institutions. Our objective is just to contrast the sustainability grade of the energy sector between 1990 and 2008 for Mexico whose government started reforms in the 1990s. It concludes that those reforms did not bring about a higher sustainability level for the energy sector.
