Sustainability criteria

Climate change adaptation and lignocellulosic bioenergy crops

Bioenergy crops can be a good strategy for climate change adaptation. Recent studies show benefits and sinergies between energy, environment and food. 

Biofuels sustainability: a lower fossil energy in fertilizers is needed

Nitrogen fertilizers are responsible of most biofuels sustainability limitations in life cycle assessments and carbon footprint. But some very realistic strategies and new findings would help to reduce their impacts.

5 benefits from a flexible fuel and biomass supply using a multi-feedstock approach

Diversification helps to reduce risk. Learn about how a flexible fuel biomass supply system can be a better approach. 

Energy crops could cover energy demand in surplus agricultural lands

A brand new study (2013) found that the projected energy demand (2035) in developing countries, can be covered with energy crops in surplus agricultural lands, then not competing with food production. 

Breaking: biofuels voted 6% Cap on crop-based biofuels in transport

The European Union assembly fixed a 6 percent limit on the use of crop-based biofuels in ground transport, seeking to spur the development of clean fuels from non-food sources.

Biofuels sustainability: Not all alternatives are the same.

From food debate and land use changes effects to biofuels sustainability, a lot of scientific findings show great differences among alternatives. We joined best scientific information. 

Land use changes: new study faces the EU commission on biofuels

Following our recent post on sustainability and land use changes, we include here a new study on land use changes that challenges the EU commission regarding biofuels. 

Land use effects: More land is available where more biofuels are produced. Are models wrong?

A very recent research publication  found harvested area with food crops to be increasing during 2000-2010 period simultaneously with biofuel expansion.

Miscanthus or cheaper perennial bioenergy crops in higher latitudes?

Miscanthus among perennial bioenergy crops in northern EU, has been promoted during last decade for heat and power production. After cultivating more than 12,000 hectares in UK, too low average yields (10-12 odt/ha per year) and high costs of delivered biomass (60-140 €/odt) are becoming major constraints

EEA: More bioenergy crops needed for more efficiency

A broader mix of bioenergy crops to reduce environmental impacts is suggested in last report issued by the European Environment Agency.
