Carbon capture and storage (CCS) is an effective technology for the mitigation of greenhouse gas emissions from large-scale fossil fuel use. Nonetheless, it is not yet commercially viable on a large scale, and its inclusion into countries' energy planning agendas depends on realistic assessments...

This study shows how the assessment of emissions reductions from CO2 capture is critically dependent on the choice of multi-gas equivalency metric and climate impact time horizon. This has implications for time-sensitive mitigation policies, in particular when considering relative impact of...

This study aims at estimating the abatement costs of CO2 emissions of the Brazilian oil refining sector. For greenfield refineries that will be built until 2030, mitigation options include the modification of refining schemes and efficiency gains in processing units. For existing refineries and...

This paper examines the sources of changes in energy use of the Brazilian economy of industries and households from 1970 to 1996, using structural decomposition analysis based on the logarithmic mean divisia index technique. Energy use can be decomposed into eight factors that explain changes in...

The use of ethanol as a fuel has been attracting increasing attention in countries that are interested in reducing their dependence on imported oil and lowering their greenhouse gas emissions. Despite this growing interest, the global ethanol market is still incipient because of the small number...

The increase in greenhouse gas concentrations in the atmosphere, energy security issues and competition for land use are putting pressure on governments and policymakers. However, these three subjects are not usually treated in integrated form. This paper shows that the implementation of energy...

The deepwater horizon accident may have shaken the sustainability ratings and indices credibility, but it also reinforced their importance. The objective of this article is to contribute to the improvement of corporate sustainability valuations by investigating if reserves profiles can affect...

This paper estimates the potential for energy-related greenhouse gas emission (GHG) reductions in Brazil, their abatement costs and proposes a number of policies to achieve these reductions. The Brazilian energy system is very peculiar as renewable energy accounts for some 45% of total primary...

A life-cycle inventory (LCI) of steel based on exergy values is presented. Exergy accounting of energy and materials flows for distinct steel production processes — conventional integrated, semi-integrated and new integrated with smelt reduction — is used to calculate and compare exergy...
