The report examines South Africa's renewable energy landscape in 2014, detailing the regulatory framework, utility-scale and private markets, and the manufacturing of components. It highlights the role of the Integrated Resource Plan (IRP) and the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) in driving capacity, while noting grid constraints and the importance of the Western Cape as an industry hub.

The roadmap proposes two visions for Colombia's bioenergy sector: one focusing on new technologies (biomethane and biomass-based power/CHP) and another combining these with the expansion of first-generation biofuels. Modeling indicates that while both scenarios increase the bioenergy share in power and gas supply, they cannot prevent an overall decline in bioenergy's share of primary energy demand due to rapid GDP growth and urbanization. The most effective emissions reductions come from power generation and CHP, particularly by avoiding methane release from landfills and animal waste. Scenario I is identified as the most efficient in terms of emissions reduction per additional hectare of land, whereas Scenario II's ambitious biofuel targets would require significant imports as domestic land is insufficient.

Landfills are the third largest source of anthropogenic methane in the United States, contributing 17.7 percent of all U.S. methane emissions. The EPA regulates large municipal solid waste (MSW) landfills and manages the voluntary Landfill Methane Outreach Program (LMOP) to encourage the capture of landfill gas (LFG) for energy production. While projects in landfills with existing capture systems are generally profitable, those requiring new systems may face net losses unless they leverage tax credits, carbon credits, or on-site electricity use. LFG projects can produce electricity, heat, or vehicle fuels, providing both climate benefits and local employment.

The report finds that King County's 2008 Geographic-plus emissions were 23.4 million MTCO2e, with transportation as the primary source. However, a Consumption-based inventory reveals a much larger footprint of 55 million MTCO2e, driven by the production of imported goods and services. To better manage these emissions, the report recommends a tracking framework focused on a 'core' scope of buildings, transportation, and waste.

The report finds that King County's 2008 emissions were 23.4 million MTCO2e via geographic accounting and 55 million MTCO2e via consumption accounting. Transportation and buildings are the primary local sources, while consumption-based emissions are driven by imported goods and services. The report recommends a 'Core' tracking framework focusing on buildings, transportation, and waste.

The study uses the WAMPS life-cycle assessment (LCA) model to evaluate leachate and landfill gas (LFG) treatment options in Estonia, finding that reverse osmosis outperforms aerobic-activated sludge for leachate treatment and that LFG energy recovery is preferable to flaring due to significant avoided impacts.

District energy systems provide centralized heating and cooling to multiple buildings via underground pipes, utilizing sources such as combined heat and power (CHP) plants, waste heat, and renewables. In the United States, over 700 such systems exist, offering benefits like reduced fuel consumption, lower peak electrical demand, and decreased greenhouse gas emissions. While high upfront infrastructure costs can be a barrier, examples from universities and city centers demonstrate significant energy savings and carbon reductions.

In 2008, Alabama imported 79% of the coal used for its electricity generation, resulting in a net expenditure of $1.39 billion. The state's electricity mix was dominated by coal (51.1%) and nuclear (26.7%). Alabama spent the most per person ($297) and the most relative to gross state product (0.82%) on net coal imports compared to other US states. To reduce this dependence, the document suggests investing in energy efficiency—noting that Alabama spent only 49 cents per person on such programs in 2007—and utilizing renewable resources which could technically meet 56% of the state's 2008 power demand.

The research paper analyzes Germany's engagement with the Clean Development Mechanism (CDM) up to July 2009, arguing that both the global mechanism and German state policy prioritize the quantity of Certified Emission Reductions (CERs) over the quality of sustainable development. The author finds that German projects are heavily concentrated in Asia, particularly China and India, and are dominated by large-scale industrial 'end-of-pipe' projects that offer minimal sustainable development benefits. The document concludes that the German government uses the CDM primarily as a tool for economic and export promotion rather than as a means to achieve genuine climate and development goals, thereby 'abusing' the mechanism's original purpose.

The document argues that capturing biogas—primarily methane—from organic waste sources is a cost-effective method to mitigate climate change and displace fossil fuels. It details the technical and economic viability of landfill gas (LFG) projects, wastewater treatment anaerobic digestion, and agricultural manure digesters, while identifying policy barriers such as high capital costs and grid interconnection issues.

The Production Tax Credit (PTC) provides financial incentives for renewable energy facilities in the U.S., offering 2.3 cents per kWh for wind, geothermal, and closed-loop bioenergy, and 1.1 cents per kWh for other technologies. While the PTC has driven significant wind capacity growth and cost reductions, the document argues that Congress's pattern of allowing the credit to expire and then granting short-term extensions has created a 'boom-bust cycle' that jeopardizes financing, jobs, and long-term development.

The study finds that CDM projects generally overestimate their emission reduction potential, with actual CER issuance reaching only 76% of the amount predicted at registration. Performance varies significantly by project type, with N2O projects over-performing (129%) and animal waste projects under-performing (28%). The analysis also indicates that in-house project development generally outperforms the use of large external consultancies, and that India showed the best host-country performance (122%) compared to China (55%) and Brazil (90%).

The document analyzes 38 Russian and 15 Ukrainian JI projects submitted to the JISC by September 2007. It finds that while Russia has a larger total volume of projected emission reductions, Ukraine's portfolio is more diverse and shows a higher rate of technology transfer and foreign investment relative to its economy. Russia's portfolio is heavily dominated by gas pipeline refurbishment, whereas Ukraine's is led by industrial energy saving and coal mine methane projects. The author attributes these differences to institutional readiness, with Ukraine having established a more effective project approval system than Russia.

The Union of Concerned Scientists analyzed the potential effects of Washington's Initiative 937 (I-937), which would require large electric utilities to source 15 percent of electricity from eligible renewable resources by 2020 and pursue cost-effective energy conservation. Under an expected case scenario, the report projects that by 2025, I-937 would result in $1.13 billion in cumulative savings on consumer electricity bills, the creation of 2,000 new jobs, and a reduction of 4.6 million metric tons of annual CO2 emissions. The analysis indicates that renewable energy and efficiency investments would be cost-competitive with conventional fossil fuel resources, providing long-term price stability and economic development, including $2.9 billion in new capital investment. Sensitivity analyses suggest that even under pessimistic conditions—such as higher wind costs or the expiration of federal tax credits—the initiative would generally still yield long-term savings and environmental benefits.

The document outlines three primary methods for companies to obtain green power: retail green power programs, renewable energy certificates (RECs), and on-site generation. It provides a business case for the transition, focusing on GHG reduction, stakeholder relations, and cost stability. The guide also details procurement strategies to minimize premiums, such as energy efficiency upgrades and demand aggregation, and explains the methodology for accounting for carbon benefits in corporate GHG inventories using e-GRID emission factors.

The report evaluates the Clean Development Mechanism's (CDM) ability to provide sustainable development benefits to developing countries. It finds that the current project pipeline is skewed toward low-development-impact industrial gas projects, is insufficient in scale to meet market demand, and is geographically concentrated in a few countries, largely bypassing least-developed nations. To address these gaps, the authors recommend reforming the Executive Board's processes, introducing top-down sectoral and policy-based CDM approaches, and increasing international financial support for high-benefit projects.

The Union of Concerned Scientists (UCS) graded U.S. states on their commitment to renewable energy, finding that 34 states received failing grades (D or F) and only 16 passed. While 19 states have enacted standards or funds projected to add 15,215 MW of capacity by 2017, the gains are highly concentrated, with California and Texas accounting for nearly 60 percent of forecasted new development. The report argues that current state-level efforts are insufficient compared to the technical potential of wind, solar, bioenergy, geothermal, and landfill gas, and advocates for a national renewable electricity standard to achieve more equitable and cost-effective energy generation.

The report evaluates U.S. state commitments to renewable energy, finding that while technical potential is vast, most states lack binding policies. It grades states based on renewable electricity standards (RES) and funds, noting that a small number of states, led by California and Nevada, drive most projected gains, while 34 states received failing grades. The authors argue for a national renewable electricity standard to ensure equitable and cost-effective growth.

Vietnam faces high vulnerability to climate change and rapidly growing emissions, projected to reach 387 Mt by 2030, primarily driven by energy supply. While the government has established the National Target Program and various energy efficiency laws, the report finds that existing and planned projects are likely to harvest only 12% of the available abatement potential between 2015 and 2030. Major barriers include low electricity and coal prices, limited technical and financial capacity among stakeholders, and institutional overlaps. The study recommends a coordinated national mitigation programme and specific sector-level interventions in REDD+, wind policy, industrial energy efficiency, and waste management.
