Natural Gas in Bolivia: Risks and Opportunities
Carlos Feu Alvim e José Israel Vargas

The recent institutional crisis in Bolivia has reactivated the Brazilian doubts about the reliability of natural gas supply from that country. An exploratory analysis of this reliability and of how to face the eventual interruption of supply and the importance for Brazil of the this external energy source is presented.

Petroleum in Brazil
Omar Campos Ferreira.

An statistical method based on the historical records of discoveries is used to evaluate the Brazilian oil reserves and the capacity to be self-sufficient during the time necessary to calmly change to new energy technologies.


Carbon Balance: The Top-Down and Bottom-Up Emissions Accounting Methodologies
Carlos Feu Alvim,  Frida Eidelman  e  Omar Campos Ferreira

The Economy and Energy Organization has carried out together with the Ministry of Science and Technology a study on the carbon balance of energy use and transformation. The publication of its results has been made through the e&e periodical in its 48 and 50 issues. In the present issue we are publishing the results corresponding to the extended Top-Down accounting process and those corresponding to the use of the coefficients calculated for the Brazilian inventory from 1990 to 1994, using the Bottom-Up process, to estimate the emissions from 1970 to 2002. By comparing the two results it is possible to evaluate their deficiencies and the possible  incoherence in the use of the two methodologies.
