The Union of Concerned Scientists (UCS) analysis indicates that a national 25 percent by 2025 renewable electricity standard would create 297,000 jobs, generate $263.4 billion in new capital investment, and lower consumer energy bills by $64.3 billion by 2025. The policy would diversify the U.S. energy mix by increasing renewable capacity from 28,000 MW in 2007 to 248,000 MW by 2025, primarily through wind, solar, bioenergy, and geothermal sources. Environmentally, the standard would reduce power plant CO2 emissions by 277 million metric tons annually by 2025, equivalent to removing 45.3 million cars from the road.

The document examines the role of Chinese investment and technology in expanding solar energy access in Kenya and sub-Saharan Africa. It highlights the potential of a joint venture between China's Tianpu Xianxing Enterprises and Kenya's Electrogen Technologies to establish a solar panel factory in Nairobi, which could significantly reduce retail prices for solar home systems. The paper argues that while Kenya has a dynamic private sector-led solar market, it lacks a comprehensive regulatory framework and government subsidies, which are essential for scaling renewable energy to meet the needs of rural populations.

The document highlights the success of renewable electricity standards in 28 U.S. states and the District of Columbia, noting they are projected to add 76,750 MW of new capacity and reduce annual CO2 emissions by over 183 million metric tons by 2025. It further advocates for a national 20 percent by 2020 standard, which would increase total renewable power to 117,000 MW and reduce projected power plant CO2 growth by 63 percent.

As of February 2009, 28 U.S. states and Washington D.C. have implemented renewable electricity standards to increase the share of wind, solar, and bioenergy in their power supplies. The Union of Concerned Scientists projects these standards will support 76,750 MW of new renewable power by 2025, reducing annual carbon dioxide emissions by over 183 million metric tons. While success varies by state—with Texas significantly exceeding its targets—the document argues that state leadership proves these standards can reduce market barriers, justifying a national renewable electricity standard to enhance energy security and fuel diversity.

The document describes an extension to the 'Embedded Carbon Emissions Indicator' project, specifically focusing on the uncertainty analysis of a UK-MRIO model. The study employs a Monte-Carlo analysis to determine error margins for direct and indirect carbon dioxide emissions associated with UK economic activities and trade. The process involved reviewing standard deviations of constraints, estimating input-output (IO) table uncertainties from constraints and matrix balancing, and calculating error propagation for embedded emissions. The report notes that such a thorough uncertainty analysis is rare in environmental MRIO studies.

The document analyzes the tension between Brazil's official government opposition to linking trade negotiations with environmental and social standards and the practical reality where Brazilian companies and social actors must adapt to these standards to maintain international competitiveness. It identifies a shift from trade being the primary vector of sustainable development themes in the 1990s to a more complex landscape involving foreign direct investment (FDI), financing, and domestic political arenas. The report highlights the impact of climate change and Amazon deforestation on the agribusiness sector, the role of voluntary and compulsory certifications, and the emergence of 'non-trade concerns' in developed nations as potential barriers to Brazilian exports.

The Smart Garage report describes a system where electrified vehicles (xEVs) communicate with the grid and buildings to optimize energy use. The document identifies a near-term focus on 'V1G' (smart one-way charging) as a practical first step toward a long-term 'V2G' (bi-directional charging) vision. It analyzes the ecosystem's value chain—including OEMs, utilities, and 'connectors'—and identifies five primary barriers: uncertain consumer demand, high battery costs, infrastructure funding, fragmented utility regulation, and a lack of communication standards. To address these, the report proposes six collaborative projects to quantify demand, analyze battery second-life value, and establish national policy frameworks.

The report argues that RGGI's design, which caps emissions only for power plants within participating states, creates a price advantage for imported electricity from coal-heavy states like West Virginia and Pennsylvania. This 'leakage' is exacerbated by excess capacity in existing coal plants and planned transmission upgrades that facilitate power flow from west to east. The authors suggest that RGGI states should implement retail-level carbon caps, prohibit contracts with high-emission plants, and prioritize transmission projects aligned with climate goals to prevent the expansion of coal-based power.

The report warns that the Regional Greenhouse Gas Initiative (RGGI) risks 'undercutting itself' because it only prices emissions from power plants within its region. This creates an economic incentive for electricity suppliers in RGGI states to import cheaper, carbon-intensive power from coal-producing states like West Virginia and Ohio. The document provides 'carbon math' showing that utilizing excess capacity from 15 existing coal plants could produce pollution 'three and a half times the cuts expected under the initiative,' and that six plants under construction nearby could emit pollution equal to '140 percent of RGGI’s reductions.' To prevent this 'leak,' the authors suggest capping the entire portfolio of local electricity suppliers, limiting contracts with polluting plants, and requiring suppliers to account for emissions from electricity produced outside the region.

The World Resources Institute (WRI) reported total CO2 emissions of 1,125 metric tons in 2006 and 1,288 metric tons in 2007, representing increases of 6% and 21% respectively over its 2000 base year. These increases are attributed to a 33% growth in staff and the expansion of office space in Washington, DC. To maintain a "net zero" balance, WRI utilized the Chicago Climate Exchange for 2006 offsets and transitioned to Certified Emission Reductions (CERs) under the Kyoto Protocol's Clean Development Mechanism for 2007, sourcing credits from wind and landfill gas projects in India and China. Management activities included achieving LEED Gold Certification for office expansion and planning a 3,600-square-foot green roof. WRI also utilized Renewable Energy Certificates (RECs) to cover 100% of its 2007 electricity use, though it maintained a conservative accounting approach by purchasing offsets for all reported emissions regardless of REC value.

The document analyzes the growth of China's wind power sector, highlighting the role of the 2005 Renewable Energy Law and strategic technology transfers from European companies. It uses Goldwind as a case study for successful private-public partnerships and argues that further international cooperation in turbine design and offshore technology is essential to meet future CO2 emission constraints.

The report examines the 'Global Connectivity System' and the policy tensions surrounding the Internet's evolution. It highlights risks to sustainable development stemming from the potential loss of net neutrality, restrictive intellectual property rights, and the shift toward 'tethered' closed devices. It also analyzes infrastructure challenges, such as the transition from IPv4 to IPv6 and the lack of universal broadband in Africa. Governance concerns focus on the internationalization of ICANN and the sustainability of the IETF's volunteer-led model. Finally, it addresses the Internet's ecological footprint, specifically the high energy demands of data centers and the environmental costs of e-waste and mineral extraction in the Democratic Republic of Congo.

The document highlights the role of school buses in reducing overall transportation emissions compared to private vehicles, while warning that diesel engine idling consumes significant fuel and poses severe health risks to children. It promotes an idle reduction curriculum developed by the Utah Clean Cities program to mitigate these impacts.

The report examines the Southern African Customs Union (SACU)—comprising South Africa, Botswana, Namibia, Lesotho, and Swaziland—and its various trade agreements. It finds that most agreements focus almost exclusively on market access and economic growth, largely ignoring social and environmental pillars of sustainable development. The study highlights the critical role of the SACU Revenue Sharing Formula in supporting smaller member states and warns that rapid trade liberalization, particularly with the EU, US, and China, may lead to significant tariff revenue losses and job cuts in sensitive sectors like textiles. It recommends that SACU integrate sustainable development guidelines into negotiations, conduct impact assessments, and increase transparency and parliamentary oversight of trade deals.

The document analyzes the foreign policy platforms of candidates John McCain and Barack Obama ahead of the 2008 US election, arguing that while Africa will likely remain a low priority for any new administration, South Africa can leverage its role as a 'pivotal state' to secure military resources, trade benefits, and health funding. It highlights diverging candidate views on energy—with Obama favoring a 'cap-and-trade' system and McCain supporting increased nuclear power and Alaskan drilling—and suggests South Africa could engage the US on carbon-trading opportunities.

The 2007 Renewable Fuel Standard (RFS) aims to reduce global warming pollution from U.S. transportation fuels by mandating renewable fuel use and requiring life-cycle carbon reductions for new facilities. While it targets a reduction of 6 percent in pollution from cars and light trucks by 2022, the Union of Concerned Scientists warns that a loophole exempting most corn ethanol and the lack of regulation for other fossil fuels could negate these benefits. The document advocates for a low-carbon fuel standard to regulate the entire fuel market.

The Union of Concerned Scientists (UCS) analyzes various technology studies to demonstrate that U.S. passenger vehicles can cost-effectively reach a fleet average of approximately 40 mpg by 2020 using conventional technology and over 50 mpg by 2030 with hybrid-electric technology. The report criticizes the National Highway Traffic Safety Administration's (NHTSA) historical use of marginal cost-marginal benefit (MCMB) analysis, which often undervalues environmental and security benefits, and recommends a total cost-total benefit (TCTB) approach to set more aggressive standards.

The Union of Concerned Scientists identifies several organizations that promote climate skepticism and disinformation, arguing they are part of a "disinformation playbook" funded by the fossil fuel industry to delay climate action. The report details the activities of groups such as the American Enterprise Institute, Heartland Institute, and the Heritage Foundation, documenting millions of dollars in contributions from ExxonMobil and Koch-funded foundations. These organizations are accused of undermining scientific consensus, attacking climate scientists, and pushing model legislation to obstruct emissions reductions.

The document advocates for a national Renewable Electricity Standard (RES) in the United States, describing it as a market-based mechanism that requires utilities to increase the share of electricity produced from renewable sources. It highlights economic benefits, such as saving consumers money and creating rural jobs, and environmental benefits, including the reduction of carbon dioxide and other harmful pollutants.

The report proposes a two-step strategy to improve the efficiency of Class-8 tractor-trailers. Step 1 focuses on technological improvements in aerodynamics, tire rolling resistance, and powertrain efficiency, which could increase fuel economy from 6.5 to 12.3 mpg. Step 2 examines the use of 'turnpike doubles'—long combination vehicles (LCVs) with two 48-foot trailers and a gross vehicle weight rating (GVWR) of 120,000 pounds—to increase freight productivity. Together, these measures could raise ton-mile efficiency by a factor of approximately 2.5, potentially saving 4 billion gallons of diesel fuel and 45 million tonnes of CO2 emissions annually for the U.S. fleet.
