November 18, That biofuels can contribute to a cleaner global energy mix is widely accepted, but the net benefits of bioenergy in terms of mitigating greenhouse gases GHG are moot. Some argue, for example, that biofuels are not sustainable because the conversion of non-agricultural land to grow energy crops could lead to a significant initial decrease in carbon storage, creating what is known as a "biofuel carbon debt". The study showed that the GHG mitigation potential of switchgrass cultivation for cellulosic ethanol production in the US was comparable on a per-hectare basis to that of reforestation and several times greater than that of grassland restoration. Switchgrass Panicum virgatum is a widely grown North American native grass proposed as biomass for the biobased economy. Co-lead author of the study, Lee R.

How competitive is biofuel production in Brazil and the United States? – Analysis - IEA

Biofuels have long been hailed as one of the potential answers to climate change. Their environmental credentials are controversial , but a handful of countries are now looking at them from another angle entirely: they want to use biofuels to try to reduce poverty among rural smallholder farmers. Such efforts are in full force in Brazil , a country that is home to both a sizeable biofuels industry and about 4. But while some of the country's biofuels policies have fallen short, others have proved a boon to the rural poor. Smallholder farmers have seen their incomes rise thanks to the introduction of more progressive standards and new rules on contract negotiations. Bastos Lima describes the Brazilian biofuels policies as "the best example" he has seen. In most cases, he says, smallholder farmers who cultivate biofuels are included only in the lowest level of the production chain.

Sugarcane-based ethanol has an energy balance that is 7 times greater than that of corn-based ethanol. Energy balance is the difference between the energy expended to convert the crop into ethanol and the amount of energy released from its consumption. There are several reasons why this occurs.

These workshops were the catalyst for a publication called Flightpath to Aviation Biofuels in Brazil, which identified gaps in establishing this industry. Embraer and Boeing took the further step of opening a joint sustainable aviation biofuel research centre in a collaborative effort to establish the aviation biofuel industry in Brazil. The centre has already started by supporting regional initiatives to foster the aviation biofuel value chain; identifying partnerships in universities, research and development centres and suppliers for aviation biofuel research in Brazil; and engaging with government agencies to establish a national policy for the development and promotion of biofuel. Case study. The blend between biofuels and conventional jet fuels has the potential to reduce particulate matter emissions from engines.
