The study assesses four scenarios for reducing greenhouse gas emissions in Tallinn's bus fleet by 2020, finding that while biodiesel and bioethanol offer the highest emission reductions, they are significantly more expensive per ton of CO2e reduced than other transport or energy sector measures.

The report assesses four fleet scenarios for the Tallinn Bus Company (TAK) up to 2020: continuing with conventional diesel, or transitioning to bioethanol (ED95), biodiesel (B100), or diesel-electric hybrids. While alternative fuels significantly reduce greenhouse gas emissions and external costs, they are more expensive to operate than conventional diesel. The study finds that the most cost-effective way to reduce local air pollution (PM and NOx) is simply replacing old buses with new Euro V and VI diesel models, as the emission gap between new diesel and alternative technologies has narrowed. Biodiesel offers the highest CO2 reduction potential, while hybrids provide the best fuel economy. The report recommends a diversified technology approach to mitigate risks associated with fuel prices and supply.

The report employs a Household Energy Economic Analysis (HHEA) model based on discrete choice analysis and stated preference surveys to understand why clean cooking technologies often fail to penetrate Sub-Saharan African markets. By surveying households in Addis Ababa, Dar es Salaam, and Maputo, the study argues that product-specific attributes—such as stove price, usage cost, safety, and smoke levels—are as critical as socio-economic factors in determining consumer choice. The findings reveal that low-income households are significantly more sensitive to upfront stove prices than usage costs, while higher-income groups show a greater willingness to pay for reduced smoke and increased safety. The report concludes that for bio-ethanol stoves to be viable, particularly for the poor, policies must address both the initial purchase price through subsidies or microfinance and the ongoing fuel costs.

The policy brief examines how Brazil's success in bioethanol production can be leveraged through the IBSA Forum to support biofuel development in South Africa and Africa. It identifies key barriers in South Africa, including a lack of a coherent national strategy and concerns over food security and land reform. The authors recommend that South Africa develop a balanced biofuel strategy, pursue collaborative R&D on second-generation biofuels, and create specific investment incentives to attract Brazilian expertise and capital.

The report examines the intersection of biomass, livelihoods, and international trade, focusing on the trade axis between the European Union and the Southern African Development Community (SADC). It highlights the growth of North-South trade in bioenergy, particularly liquid biofuels like bio-ethanol and biodiesel, driven by EU commitments to reduce greenhouse gas emissions in transport. The document weighs the potential for economic growth and livelihood creation against risks of environmental degradation and economic exploitation, ultimately offering recommendations for future research, policy, and capacity building rather than definitive conclusions.

The report analyzes China's biofuels sector, focusing on the transition from grain-based ethanol to non-grain feedstocks grown on marginal land. It finds that government subsidies, including direct payments and tax exemptions, are essential for the industry's viability but may undermine food security, increase food prices, and cause environmental degradation. The authors conclude that biofuels have a negligible impact on China's energy security and recommend eliminating direct production subsidies.

The document argues that while SADC has significant potential for sugarcane-based ethanol production to reduce petroleum import dependency, regulatory uncertainty—specifically the lack of blending mandates and pricing formulas—is the primary barrier to investment. It suggests that a regional market could leverage South Africa's demand and the production capacity of other member states, potentially creating millions of jobs and providing significant electricity co-generation.

The report assesses the current state of cooking energy in Madagascar, where over 80% of rural households rely on wood and over 60% of urban households use charcoal. It models a 'Base Scenario' aligned with national policy and a 'Universal Access Scenario' aligned with SDG7, estimating the fuel production potential for bioethanol, biogas, and pellets. The analysis highlights that while bio-fuels have significant potential without impacting food security, the primary barrier to adoption is the cost of fuel, which represents 97.1% of transition costs. Transitioning to clean cooking could reduce residential energy consumption by up to 65% and prevent thousands of deaths from indoor air pollution by 2030.

The report evaluates Malawi's progress toward clean cooking goals, highlighting a significant gap between current ownership and 2030 targets. It identifies affordability and low stove durability as primary barriers, estimating a $108.8M investment needed for the Compact scenario and $246.0M for the more ambitious IEP scenario. The IEP scenario envisions a total phase-out of fuelwood and charcoal by leveraging universal electrification for e-cooking and expanding biofuels. The report emphasizes the need for durable stoves, innovative financing, and regional strategies, particularly in the Northern region, to reduce health risks and gender-based time burdens associated with fuel collection.

The document criticizes the Indonesian government's push for B50 and Bioethanol (E20) as a response to Middle East oil supply crises. It claims these policies will lead to massive deforestation, carbon emission increases, and the 'whitewashing' of illegal palm oil plantations. The author asserts that the program benefits conglomerates and creates trade dependency on the US, proposing instead a shift toward public transportation to reduce fuel demand.
