We analyze the relationships between biodiesel, ethanol and related fuels and agricultural commodities with a use of minimal spanning trees and hierarchical trees and Granger causality. We construct this trees for different frequencies (weekly, monthly and quarterly). We find that in short-term,...

We propose a new approach to analyze relationships and dependencies between price series. For the biofuels markets and the related commodities, we study their mutual responsiveness, which can be understood as price cross-elasticities. Several methodological caveats are uncovered and discussed....

The consensus view of scientists is that the build-up of greenhouse gases (GHG) in the atmosphere is causing global warming. To reduce the probability of severe climate-change impacts and costs occurring, global GHG emissions need to be reduced substantially over coming decades. The United...

The oil price hike in 2007-08 underlined the vulnerability of Indonesia’s energy subsidy policy to oil price volatility. In addition to entailing significant economic and environmental costs, energy subsidies put pressure on the public budget and benefit mostly rich households. Phasing them...

Purpose – The Renewable Energy Directive (RED) is a specific example of life cycle assessment (LCA) applied to legislative measures that have far-reaching implications for economic operators. This paper aims to analyze LCA limitations for biofuels based on RED from an environmental accounting...

The global land use implications of biofuel expansion have received considerable attention in the literature over the past decade. Model-based estimates of the emissions from cropland expansion have been used to assess the environmental impacts of biofuel policies. And integrated assessment...

To meet its objectives of expanding biofuel production, Brazil is confronted with the need to allocate new land areas for energy crops. This raises issues to be resolved concerning future exports to Europe. The European Directive 2009/28/CE of 23 April 2009 on the promotion of the use of energy...

Life cycle analysis (LCA), as it is currently applied, can lead to biased results. The use of LCA information is particularly sensitive when taken in the context of government regulatory frameworks. Indeed, instead of encouraging companies to reduce their impact on the environment,...

For the first time, we apply the wavelet coherence methodology on biofuels (ethanol and biodiesel) and a wide range of related commodities (gasoline, diesel, crude oil, corn, wheat, soybeans, sugarcane and rapeseed oil). This way, we are able to investigate dynamics of correlations in time and...

We use a gendered dynamic CGE model to assess the implications of biofuels expansion in a low-income, land-abundant setting. Mozambique is chosen as a representative case. We compare scenarios with different gender employment intensities in producing jatropha feedstock for biodiesel. Under all...
