The 'Environmental Impact Assessment Guideline for Renewable Energy Projects' outlines the regulatory framework and procedural requirements for deploying renewable energy technologies in South Africa. It details the environmental impacts of various technologies—including wind, solar, biomass, and hydropower—and maps these to the specific national legislation and authorisations required under the National Environmental Management Act (NEMA) and other sectoral laws. The guide provides a structured approach to the Basic Assessment (BA) and Scoping and Environmental Impact Reporting (S&EIR) processes, including timeframes, stakeholder roles, and mitigation strategies to ensure sustainable development.

The document outlines the economic and environmental benefits of transitioning Oregon's transportation sector from petroleum to clean fuels, specifically electricity and biofuels. It highlights the cost-effectiveness of electric vehicles (EVs) and the state's potential to produce advanced biofuels from waste, residues, and energy crops. Central to this transition is the Clean Fuels Program, which aims for a 10 percent reduction in carbon emissions per unit of fuel by 2025 and aligns with regional policies in California and British Columbia to create a larger market for low-carbon alternatives.

The report argues that Brazil's historical land abundance led to a misallocation of resources and land-intensive agricultural models. However, it demonstrates that productivity gains can be achieved without further deforestation by converting degraded pastures to crops and improving technology dissemination, credit access, and infrastructure. It highlights the success of the PPCDAm and DETER system in reducing Amazon deforestation but warns of new challenges, such as smaller-scale clearings and deforestation shifting to areas outside the Amazon and around protected zones.

Skanska advocates for a progressive COP21 agreement to provide legislative certainty for green investments and details its 'Journey to Deep Green' strategy. This approach focuses on near zero environmental impact and net zero energy performance, as demonstrated by the Solallén residential neighbourhood in Sweden and the Bentley Works facility in the UK, both of which utilize solar and renewable energy systems to reduce carbon footprints.

The document outlines the implementation of President Obama's Climate Action Plan (CAP), focusing on three primary goals: cutting U.S. carbon pollution, preparing for climate impacts, and leading international efforts. Key achievements include the finalization of the Clean Power Plan to reduce power sector emissions by 32% by 2030, the establishment of the State, Local, and Tribal Leaders Task Force on Climate Preparedness and Resilience, and the formation of bilateral climate agreements with China, India, and Brazil. The report details a series of executive orders, agency regulations, and budget requests aimed at reducing greenhouse gas emissions and enhancing national infrastructure resilience.

The report details the application of the Smart Energy Path methodology in Benin, Mali, and Togo, emphasizing a multi-sectoral, participatory approach to energy planning. It highlights the vulnerability of these countries' energy systems to climate change and argues for prioritizing collective energy services—such as those for health and education—over individual household electrification. The project utilized the TIPEE multidimensional assessment tool to identify gaps in energy policy and data, concluding that inclusive governance involving non-energy sectors is essential for creating resilient and sustainable energy frameworks.

The Makeni Project has provided significant infrastructure, employment, and agricultural training in Sierra Leone, but its transformative potential is limited by poor government oversight and risks to local resource access.

The United States generates over 250 million tons of municipal solid waste and 9 trillion gallons of wastewater annually, yet recovers less than 18 percent of the potential 10.5 million metric tons of biomethane available. Current landfill systems are inefficient, leading to significant fugitive methane emissions, while many wastewater treatment facilities lack anaerobic digesters or flare excess biogas. The document advocates for a shift toward organic waste diversion and anaerobic digestion, which can result in negative lifecycle emissions. It highlights the potential for waste-derived fuel to power 10.4 million cars or 13.7 million homes and suggests that the EPA's designation of biogas-derived electricity as a renewable biofuel could generate 90 million renewable identification numbers (RINs) annually to support electric vehicle infrastructure.

The document examines the potential for mid-level ethanol blends (E25 to E40) to improve fuel efficiency and reduce greenhouse gas emissions in the U.S. transportation sector. It highlights that a significant portion of the existing vehicle fleet and fuel infrastructure can accommodate these blends with moderate costs. Research indicates that increasing ethanol content can enhance engine performance and that a nationwide E25 blend could reduce transportation GHG intensity by 5 to 9 percent.

The document examines the potential for mid-level ethanol blends (E25-E40) to serve as high-octane fuels, reducing GHG emissions and increasing efficiency for both existing and future internal combustion engines. It highlights that while infrastructure and 'blend wall' challenges exist, a significant portion of the current U.S. fleet—including 17.4 million FlexFuel Vehicles and 80% of cars newer than 2001 (for E15)—can accommodate higher blends. The text details the role of ethanol in preventing engine knock, the lifecycle GHG benefits of corn and cellulosic ethanol, and the DOE's Optima Initiative aiming to reduce petroleum consumption by 30% by 2030.

The document argues that the Renewable Fuel Standard (RFS) has failed to meet its goals of producing clean renewable fuels and protecting consumers, instead primarily incentivizing corn ethanol. It highlights negative impacts including increased greenhouse gas emissions from land conversion, water pollution in the Mississippi River Basin and Gulf of Mexico, and increased food prices and land displacement in developing countries and the United States.

The Clean Air Task Force (CATF) asserts that the Renewable Fuels Standard (RFS) has failed its primary goal of reducing greenhouse gas emissions, instead promoting corn ethanol production that increases emissions and raises food prices. The document highlights that corn ethanol produced between 2010 and 2015 failed to meet the 20% GHG reduction mandate and that the RFS has failed to stimulate the production of advanced cellulosic biofuels.

The document examines the drivers and impacts of biofuel expansion in Sub-Saharan Africa, specifically focusing on jatropha- and sugarcane-based fuels. It argues that while biofuels are driven by goals of energy security and economic development, they are linked to significant trade-offs including GHG emissions, deforestation, and food insecurity. The author concludes that the lack of comprehensive understanding of these trade-offs, combined with institutional and market failures, hinders the sustainability of biofuel investments in the region.

The Clean Air Task Force (CATF) supports the readoption of California's Low Carbon Fuel Standard (LCFS) through 2020 but argues against reducing the indirect land use change (ILUC) emissions score for corn ethanol. CATF contends that current modeling, specifically the CA GTAP-BIO model, underestimates emissions by ignoring water scarcity, failing to differentiate between commercial and non-commercial forests, and using flawed yield price elasticity assumptions. The document also highlights the negative impact of corn ethanol on global food security and proposes liquid ammonia as a scalable, low-carbon fuel alternative for the post-2020 period.

The Clean Air Task Force supports the re-adoption of California's Low Carbon Fuel Standard (LCFS) through 2020 but opposes reducing the carbon intensity value for corn ethanol. The organization argues that the current modeling used to justify a lower indirect land use change (ILUC) score is based on subjective decisions, specifically the assumption that biofuel expansion leads to a reduction in food consumption that provides a climate benefit. CATF contends that if food consumption declines were limited, corn ethanol's ILUC emissions would increase substantially, and that relying on corn ethanol would hinder the development of more effective compliance options.

Bonaire transitioned its electricity system after a 2004 fire destroyed its diesel plant, implementing 11 MW of wind capacity and 6 MWh of battery storage. The island currently generates 40–45 percent of its annual electricity from wind and aims for 100 percent renewables by utilizing local algae for biodiesel in its remaining generators. This shift has reduced electricity costs to $0.22/kWh, compared to $0.36/kWh or more on nearby islands, and increased energy reliability and local employment.

The paper examines the conflict between bioenergy production and the global need for food, feed, and carbon sequestration. It argues that dedicated land use for bioenergy—including crop-based biofuels and cellulosic energy crops—exacerbates a projected 70 percent crop calorie gap by 2050. The authors contend that bioenergy is an inefficient use of solar radiation compared to solar photovoltaics (PV), which can produce over 100 times more energy per hectare. Furthermore, the document identifies a systemic 'double counting' error in greenhouse gas accounting that erroneously treats biomass as carbon-free. It recommends phasing out subsidies and mandates for land-dedicated bioenergy while prioritizing 'additional' biomass sources such as municipal waste and specific residues.

The document examines the EU's biofuels policy framework, tracing its development from the 2003 Directive to the 2015 ILUC Directive. It highlights the tension between achieving renewable energy targets in transport and the negative externalities associated with first-generation biofuels, such as indirect land use change (ILUC) and food price volatility. The brief notes that while biofuels have increased their share in transport from under 0.5% in 2003 to over 5% by 2012, technical 'blend walls' and a lack of investment in second-generation biofuels remain significant hurdles. It concludes that the ILUC Directive attempts to balance these issues by capping food-crop biofuel contributions at 7% and incentivising advanced biofuels and electrification.

The report examines the water-energy-food (WEF) nexus in Latin America and the Caribbean, highlighting how the region's reliance on natural resources creates critical trade-offs. It argues that while LAC is resource-abundant, fragmented governance and climate change threaten security. The document proposes a framework for action based on infrastructure, information, institutions, and investment to transition toward climate-compatible development.

The document examines the rollout of biofuels and agribusiness in Southeast Asia, finding that promised poverty reduction and rural development benefits often fail to materialize. It highlights systemic issues including unclear land tenure, the vulnerability of small-scale producers, and weak enforcement of environmental laws. The authors argue that investments frequently precede inclusive development planning, leading to social tensions and ecological risks, and recommend prioritizing 'upstream' planning and strengthening dispute resolution mechanisms.
