The report finds that low-carbon energy transitions do not automatically improve social equity and can replicate existing structural inequalities if power asymmetries are not addressed. While some technologies like household solar provide benefits, others—particularly large-scale hydropower and biofuel plantations—often lead to land loss, displacement, and precarious employment. The authors argue that institutional frameworks and participatory processes, rather than the technology itself, determine whether a transition is just.

The document presents a data table comparing emission standards (LDV), gasoline octane levels, refinery counts, import percentages, and sulfur content in gasoline and diesel for various countries in Latin America and the Caribbean. Key data points include Chile's transition to Euro 6 by 2022, Colombia's target of Euro 6 by 2030, and specific sulfur limits ranging from 15 ppm in Mexico to 8000 ppm in Cuba.

The document advocates for a transition to cleaner transportation fuels in the US Midwest, highlighting the region's leadership in biofuels and wind energy. It proposes clean fuels standards as a mechanism to reduce the carbon intensity of transportation, promote higher ethanol blends, and accelerate the adoption of electric vehicles (EVs).

The document examines the soy value chain from Argentina to Europe, highlighting how environmental and social costs are externalized to the producer. It argues that achieving SDGs 12 and 17 requires consumption-based accounting and bilateral cooperation to manage these spillovers.

The report examines Indonesia's transport fuel subsidy regime, noting that while 2015 reforms initially saved over USD 15 billion, subsidies re-emerged as the government fixed prices despite rising international oil costs. This underpricing, particularly of 'Premium' gasoline, resulted in an estimated IDR 54.5 trillion in foregone revenue for Pertamina between 2014 and 2019. The author argues that subsidizing low-quality, high-sulphur fuels exacerbates urban air pollution and health costs, citing a 2010 study where air pollution-related treatment costs in Jakarta reached IDR 38.5 trillion. The document also analyzes the life-cycle emissions of biodiesel and electric vehicles, noting that EVs powered by Indonesia's coal-heavy grid may increase global warming potential compared to internal combustion engines. To resolve these issues, the report proposes three pricing models—smoothing, ratcheting, and cap-and-floor—to minimize price volatility while ensuring fiscal sustainability.

Mighty Earth asserts that food-based biofuels are environmentally damaging, contributing to climate change through emissions and the release of sequestered soil carbon, while causing habitat loss and water contamination.

The report identifies 5.5 million km2 of 'REMAIN' land in sub-Saharan Africa potentially available for biofuel production after accounting for food security and conservation. Under current conditions, RSB-compliant production on prime and good quality land could yield 165 mt of aviation biofuel per annum, with miscanthus identified as the most promising feedstock. However, this potential is projected to decrease by approximately 40% by 2050 due to cropland expansion for food and climate change impacts. The study concludes that the region could meet between 30% and 90% of the projected 2050 global demand for alternative aviation fuels, depending on whether moderately suitable land is utilized.

The analysis finds that available clean fuels, including electricity, ethanol, biodiesel, and renewable diesel, could support a 11.2 percent reduction in average carbon intensity by 2028. Under an 'Accelerated Progress Scenario', reductions of 13.1 percent by 2028 and 16.5 percent by 2030 are achievable. The study also models the impact of electric vehicle (EV) penetration, noting that a 'High EV' scenario could reach a 15.9 percent reduction by 2030, while a 'Low EV' scenario would reach 11.1 percent. Additionally, the report estimates that credit values at $100 per metric ton of CO2 equivalent could fund EV rebates growing from $2,200 per vehicle in 2022 to $3,000 in 2028.

The document highlights that transportation accounts for 43 percent of Washington's global warming pollution. It advocates for a clean fuel standard to transition from imported petroleum to locally produced low-carbon alternatives, including electric vehicles (EVs), biomethane, and various biofuels. The report emphasizes the economic benefits of keeping fuel spending within the state and the potential for Washington to lead in sustainable aviation fuels.

The document describes Thailand's top-down approach to developing a bioeconomy focused on adding value to existing commodities like sugarcane and cassava. It highlights a model where the private sector drives innovation while the government facilitates through tax incentives, R&D funding, and regulatory easing. However, the authors note significant challenges regarding social equity, as the system prioritizes large industrial players over smallholder farmers.

Mighty Earth and a coalition of environmental groups support the reduction of US biodiesel mandates, arguing that the fuel is not 'green' because it relies on virgin vegetable oils that drive deforestation in Latin America and Southeast Asia. The document highlights that biodiesel production contributes to carbon emissions and water pollution, such as the Gulf of Mexico's Dead Zone. While the EPA initially sought input on reducing mandates, the document notes that President Trump later intervened to reverse this course due to pressure from agricultural lobbying groups.

The document examines how California's LCFS and Cap-and-Trade Program work together to reduce transportation emissions. The LCFS mandates a reduction in the carbon intensity of fuels, while Cap-and-Trade puts a price on carbon and generates revenue for clean technology investments. The author argues that neither policy is sufficient alone and recommends extending both to 2030 to provide the stability needed for long-term infrastructure and vehicle transitions.

The document outlines the economic and sustainability benefits of organic waste separation for Western Cape businesses, highlighting a provincial goal to ban the landfilling of all organic waste by 2027. It categorizes available waste-to-value solutions—including waste-to-pharma, food, feed, soil, and energy—and provides a framework for onsite management, such as appointing a waste champion and implementing source separation. The brief also details relevant legal frameworks, including the National Environmental Management: Waste Act and City of Cape Town by-laws, emphasizing the need for accredited service providers.

Indonesia faces imminent energy security challenges, with demand for electricity and transport fuel expected to grow rapidly by 2030. While the government has set ambitious targets for renewable energy (23% by 2025) and emission reductions (29-41% by 2030), current investments follow a 'business as usual' fossil fuel path. Structural barriers include policy inconsistency, limited fiscal space, and a political culture of transactional politics and decentralisation that often favours the exploitation of domestic coal. However, opportunities exist in geothermal energy, waste-to-energy, and energy efficiency, alongside governance reforms like the 'One Map' initiative and increased foreign direct investment to mitigate the financial risks of transitioning to a low-carbon economy.

The document introduces agent-based modelling (ABM) as a bottom-up approach to study complex social and environmental systems by simulating the interactions of autonomous agents. It argues that ABM is particularly useful for problems involving decentralized interactions and non-linear dynamics where traditional top-down models fail. The authors highlight ABM's potential as a stakeholder engagement tool and its ability to be integrated with qualitative and quantitative methods like GIS and social network analysis. Four case studies are presented: disaster resilience in Turkey, agroforestry adaptation in Cameroon, biodiesel transitions in Malaysia, and artisanal fisheries management in Kenya.

The Clean Air Task Force (CATF) opposes New York City's proposed biodiesel heating fuel mandate, arguing that increasing demand for vegetable oil-derived biodiesel drives the expansion of palm oil production. This expansion leads to the destruction of tropical peatland forests, particularly in Indonesia and Malaysia, resulting in significant carbon dioxide releases and public health crises. CATF contends that even soybean-based biodiesel contributes to these impacts through global market fungibility and that current USEPA lifecycle analyses underestimate these greenhouse gas emissions.

The study uses a GTAP-BIO computable general equilibrium model to analyze the relationship between biofuel mandates and feedstock price volatility. It finds that while yield declines significantly increase prices for sugar crops, grains, and oilseeds, the impact on biofuel prices themselves is small. The authors argue that flexible policies, specifically production waivers during low-yield years, can significantly reduce feedstock price spikes, though the effectiveness of such waivers decreases if their implementation is delayed by one year.

The document analyzes the evolution of ethanol use in the U.S., noting that while E10 blends have reduced oil dependence, corn-based ethanol causes significant environmental damage and can spike global food prices. It argues for a shift toward advanced biofuels derived from wastes, agricultural residues, and perennial crops to lower lifecycle emissions and protect biodiversity. The report forecasts that by 2050, emissions from biorefineries, agriculture, and land use can be substantially reduced through technological optimization and smarter crop choices.

The document outlines a pathway for California to halve its oil use by 2030 by extending and enhancing existing policies on vehicle efficiency, electrification, and land use planning.

The document examines the transition of isolated communities from a total dependence on imported oil to renewable microgrids. It identifies high electricity costs, environmental concerns, and abundant local resources as primary drivers for this shift. Through ten detailed case studies—including locations such as Kodiak, Alaska, and El Hierro, Spain—the report highlights the critical role of energy storage (batteries, flywheels, and pumped hydro) and energy efficiency in maintaining grid stability. Key findings indicate that renewable integration can significantly reduce retail electricity rates and improve system resiliency, though it often requires a phased technical approach to overcome stability and logistical challenges.
