Many biofuels are associated with lower greenhouse-gas emissions but have greater aggregate environmental costs than gasoline. 
Fields of Gold : The Bioenergy Debate in International Organizations
The concept of producing energy from biomass has, for the last two decades, occupied attention of policy-makers, private industries, researchers and civil societies around the world. The highly con
Biofuels: Waste Not Want Not
TLDR
The Reports “Land clearing and the biofuel carbon debt” and “Use of U.S. croplands for biofuels increases greenhouse gases through emissions from land-use change” underscore the sobering effects of land clearing.
Sustainability Aspects of Bioenergy and Nutrient Recovery from Marine Biomass Baltic Sea case studies
Coastal areas around the world are experiencing environmental problems such as climate change and eutrophication. These, in turn, lead to emerging challenges with excessive amounts of biomass that ...
Biofuels technology development in Southern Africa
ABSTRACT The benefits of biofuels depend on the feedstock, conversion pathway and local context. This paper assesses biofuels technology readiness and developments to provide foresight to biofuels
Towards Sustainable Production of Biofuels from Microalgae
TLDR
This paper aims to analyze and promote integration approaches for sustainable microalgal biofuel production to meet the energy and environmental needs of the society.
Future perspectives of 2nd generation biofuels
Fossil independence and substantial reductions in CO2 emissions seem to be possible with 2nd generation biofuels. New technologies allow a full carbon-to-fuel conversion of non-edible plant parts
The biofuel potential of municipal solid waste
The world in the 21st century is facing a dual crisis of increasing waste and global climate change. Substituting fossil fuels with waste biomass‐derived cellulosic ethanol is a promising strategy to
Agrofuels in Thailand: Policies, practices and prospects
Agrofuels, defined here as agriculture-based liquid transportation fuels, have been widely promoted as a renewable, sustainable, energy source which could reduce dependency on fossil-fuel imports.
Sustainable Bioenergy from Biofuel Residues and Wastes
Introduction Increasing energy consumption with the ever present limitations of nonrenewable resources is a c oncern that is prevalent in modern society and di ctates immediate attention. With

Carbon Mitigation by Biofuels or by Saving and Restoring Forests?
The carbon sequestered by restoring forests is greater than the emissions avoided by the use of the liquid biofuels.
Ethanol Can Contribute to Energy and Environmental Goals
TLDR
It is already clear that large-scale use of ethanol for fuel will almost certainly require cellulosic technology and new metrics that measure specific resource inputs are developed, but further research into environmental metrics is needed.
Carbon-Negative Biofuels from Low-Input High-Diversity Grassland Biomass
TLDR
Low-input high-diversity mixtures of native grassland perennials can provide more usable energy, greater greenhouse gas reductions, and less agrichemical pollution per hectare than can corn grain ethanol or soybean biodiesel.
Switch to Corn Promotes Amazon Deforestation
The United States is the world's leading producer of soy. however, many u.s. farmers are shifting from soy to corn (maize) in order to qualify for generous government subsidies intended to promote
Hydrogen production. Green algae as a source of energy.
TLDR
Interconversion between these two forms of energy suggests on-site utilization of hydrogen to generate electricity, with the electrical power grid serving in energy transportation, distribution utilization, and hydrogen regeneration as needed.
Life-cycle assessment of net greenhouse-gas flux for bioenergy cropping systems.
TLDR
The DAYCENT biogeochemistry model was used to assess soil GHG fluxes and biomass yields for corn, soybean, alfalfa, hybrid poplar, reed canarygrass, and switchgrass as bioenergy crops in Pennsylvania, USA to determine the net effect of several bioenergy cropping systems on greenhouse-gas (GHG) emissions.
Environmental, economic, and energetic costs and benefits of biodiesel and ethanol biofuels.
TLDR
Transportation biofuels such as synfuel hydrocarbons or cellulosic ethanol, if produced from low-input biomass grown on agriculturally marginal land or from waste biomass, could provide much greater supplies and environmental benefits than food-basedBiofuels.
