The document outlines the two primary forms of carbon pricing: emissions trading schemes (ETS) and carbon taxes. It details the European Union Emissions Trading Scheme as the world's largest, alongside regional programs like the RGGI in the US and the Tokyo Cap and Trade Program. It also lists numerous national carbon taxes, noting Finland as the first to introduce one in 1990, and describes hybrid systems in Australia and New Zealand.

The document details US efforts to reach a goal of one million electric vehicles by 2015, focusing on federal, state, and local deployment programs, the role of commercial and government fleets, and proposed legislation to incentivize PEV adoption and infrastructure.

The report examines the application of hybrid-electric, battery-electric, fuel cell, and plug-in hybrid technologies in the US trucking sector. It highlights specific use cases, such as urban delivery, port drayage, and auxiliary power units, noting that while medium- and heavy-duty trucks make up only 4% of road vehicles, they account for approximately 20% of transportation fuel consumption. The document argues that expanding electrification is a key strategy for doubling truck fuel efficiency and halving projected US oil consumption over 20 years.

The report argues that carbon pricing is likely to improve air quality in California because the most feasible GHG abatement strategies—such as energy efficiency and fuel switching—also reduce local air pollutants. Using data from the European Union (EU) Emissions Trading Scheme (ETS), the authors find a statistically significant negative relationship between carbon prices and emissions of both GHGs and local air pollutants (sulfur dioxide, nitrogen oxides, and particulate matter). Notably, EU oil refineries showed stronger reductions in local air pollutants than the average industrial facility. While cogeneration is identified as the only strategy that could potentially increase local emissions, the report suggests that existing air quality regulations and new source reviews in California should prevent such outcomes. The authors recommend that California regulators use industrial audits to maximize synergies between GHG and LAP abatement and consider financial incentives for high-benefit projects in poor air quality areas.

The document identifies five key realms for renewable energy policy: direct purchase mandates, improving the business case through financial incentives, removing non-price barriers, supporting research and development, and addressing grid intermittency. It recommends that Japan maintain its generous feed-in tariffs, expand demand response, and unbundle transmission from generation to increase competition. The report provides detailed international case studies from the US, Germany, and other nations to illustrate effective mechanisms such as Green Banks, loan guarantees, and carbon taxes.

The Union of Concerned Scientists (UCS) estimates that 677 million tons of sustainable biomass could be available in the U.S. by 2030, enough to produce 54 billion gallons of ethanol or 732 billion kilowatt-hours of electricity. The report advocates for a shift toward non-food biofuels and biopower sources—such as perennial energy crops, agricultural residues, and waste materials—while explicitly excluding whole trees due to concerns over carbon storage loss. It emphasizes that bioenergy must be scaled appropriately to avoid competing with food production and causing indirect land-use changes that could eliminate climate benefits.

The document describes the technical operation of battery electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), noting that a range of 60 to 120 miles can satisfy the vast majority of daily travel needs. It details the 2012 U.S. market, highlighting the Chevrolet Volt and Nissan LEAF as dominant models and comparing specifications for several other vehicles. The text analyzes the economic impact of battery costs, the necessity of charging infrastructure, and the role of federal and state tax credits in making PEVs commercially viable.

The document distinguishes between all-electric vehicles (EVs) and plug-in hybrid electric vehicles (PHEVs), noting that EVs offer lower maintenance and no tailpipe emissions. It highlights that while the U.S. market is dominated by the Chevrolet Volt and Nissan Leaf, new models like the Tesla Model S provide significantly higher ranges. The text identifies battery costs as the primary expense for PEVs, with projections suggesting prices could drop from $690 per kWh in 2012 to $160 per kWh by 2025. It also details the disparity between the 8,000 public charging stations and 150,000 gasoline stations in the U.S., and outlines federal tax credits up to $7,500 and various state-level incentives in California, Washington, and Colorado.

The document evaluates the British Columbia carbon tax as an effective model for low-carbon development that has reduced emissions without hindering economic growth. It compares BC's approach with other Canadian provincial and federal strategies, highlighting a closing gap in carbon pricing across the country. The briefing identifies key risks to future success, including the expansion of the natural gas sector and the lack of carbon pricing in the United States. IISD recommends retaining the tax and considering integrated mitigation and adaptation strategies.

The document analyzes the REDD+ supply chain, identifying key private sector roles including investors, producers, brokers, advisors, auditors, and end-buyers. It highlights that while some pioneering investment funds and multinational firms are engaging through voluntary markets and CSR initiatives, significant barriers remain, specifically a lack of policy certainty and unresolved land tenure and carbon ownership issues. The brief argues that scaling up private investment requires a shift toward compliance carbon markets, the implementation of nested crediting frameworks for direct performance-based payments, and the integration of deforestation-driving industries, such as extractive sectors, into the REDD+ dialogue.

The report analyzes the private sector's role in the REDD+ supply chain, identifying key players as investors, producers, brokers, advisors, auditors, and end-buyers. It highlights critical barriers such as policy uncertainty, land tenure disputes, and the need for robust social and environmental safeguards. The document proposes strategies to scale up private investment, including the integration of REDD+ into compliance carbon markets, the adoption of nested crediting frameworks, and the inclusion of extractive industries in conservation dialogues.

The research paper develops a methodology for scenario analysis of consumption-based GHG emissions, moving beyond traditional production-based accounting. It introduces a framework using a modified Kaya Identity to forecast emissions by analyzing population, consumption activity, and GHG intensity. The authors provide a catalogue of low-GHG behavioral measures across food, goods, services, construction, transport, and home energy. Piloting the method in Seattle and the U.S., the study finds that while aggressive behavioral shifts and production improvements can reduce consumption-based emissions by 47% by 2030, the resulting levels remain significantly above the global average required to limit warming to 2°C.

The paper examines the 'mitigation timing question' for bioenergy, specifically how the time-frame used to calculate carbon payback affects whether bioenergy is seen as a greenhouse gas reduction or increase. The author critiques several existing approaches—including those by O'Hare et al. and Cherubini et al.—for failing to account for emissions trajectories and the disproportionate value of immediate mitigation. The author contends that once a goal of immediate mitigation is adopted, future reductions must be discounted due to the time value of money, technological progress, and the 'option value' of delaying specific commitments. The author suggests a minimum discount rate of 5% per year, which mathematically aligns with a 20-year payback period, similar to the approach used by the European Commission.

The brief highlights the role of the 2008 Farm Bill in stimulating the U.S. biofuels industry and reducing oil dependence. It details specific programs like the Biomass Crop Assistance Program (BCAP) and the Biorefinery Assistance Program, noting that while initial investments of less than $2 billion have shown promise, significant further investment is required to meet Renewable Fuel Standard (RFS) targets for 2022. The author emphasizes that shifting to biofuels can improve energy security, support rural economic development, and mitigate climate change.

The document describes small wind turbines (0.3 to 100 kW) as tools for distributed generation that reduce reliance on fossil-fuel plants and the electrical grid. It details the differences between horizontal axis (HAWT) and vertical axis (VAWT) turbines, the shift from off-grid to grid-connected systems, and the role of community wind projects. It highlights the United States' leadership in manufacturing and installed capacity, while outlining key federal incentives like the Investment Tax Credit (ITC) and the USDA Rural Energy for America Program (REAP).

The report finds that electric vehicles (EVs) in the United States generally produce lower global warming emissions than average gasoline vehicles, though the extent of the benefit varies by regional electricity grid mix. It also demonstrates that EVs offer significant annual fuel-cost savings, which can be further maximized through time-of-use (TOU) electricity rate plans.

The Union of Concerned Scientists evaluated the ten largest publicly owned utilities (POUs) in California based on their 2010 compliance with the state's Renewables Portfolio Standard (RPS). While these utilities collectively increased their RPS-eligible investments from 4.1% of retail sales in 2003 to 18.8% in 2010, the report finds significant disparity in how this was achieved. Some utilities, such as Silicon Valley Power and Modesto Irrigation District, are categorized as "running ahead," while others, like Roseville Electric and Imperial Irrigation District, are labeled as having a "false start" due to a reliance on short-term contracts that do not promote new clean energy development. The report emphasizes that long-term contracts and ownership of facilities are essential to meet the increased 33% RPS requirement for 2020 and to reduce the state's continued heavy reliance on fossil fuels.

The Union of Concerned Scientists evaluated how California's 10 largest publicly owned utilities (POUs) performed against the 20 percent by 2010 Renewables Portfolio Standard (RPS). While collective RPS-eligible investments rose from 4.1 percent in 2003 to 18.8 percent in 2010, the report found significant variance in utility performance. Three utilities—Silicon Valley Power, Turlock Irrigation District, and Modesto Irrigation District—were categorized as "sprinting ahead," while others were labeled as "on the right track" or a "false start." The analysis highlights that reliance on short-term contracts fails to provide financial security for developers and does not effectively promote new clean energy facilities. To meet the strengthened 33 percent by 2020 requirement, the report recommends that POUs prioritize long-term contracts and direct ownership of projects to reduce fossil fuel reliance and stabilize prices.

The report analyzes how California's 10 largest publicly owned utilities (POUs) met the 2010 RPS goal of 20 percent renewables. While collective RPS-eligible investments rose from 4.1 percent in 2003 to 18.8 percent in 2010, the quality of these investments varied. The authors emphasize that long-term contracts for new facilities are the most effective way to drive new clean energy development and stabilize rates. The report categorizes POUs into three groups: those 'sprinting ahead' (e.g., Silicon Valley Power), those 'on the right track' (e.g., LADWP), and those with a 'false start' (e.g., Imperial Irrigation District). It concludes with recommendations for the California Energy Commission (CEC) and POUs to prioritize long-term investments and improve reporting to meet the 33 percent RPS by 2020.

The report argues that the EU ETS is failing due to a massive oversupply of allowances caused by the 2008 economic recession and industrial overallocation. Sandbag identifies a total excess of 3.1 billion tonnes (Gt) of allowances, including 2.2Gt from obsolete demand forecasts and 0.9Gt from industrial overallocation. The document highlights that 78% of the net surplus is concentrated among ten steel and cement companies, which have generated significant revenues from selling surplus permits. To remedy this, the report recommends the permanent cancellation of 3.1Gt of allowances from Phase 3 auctions, the establishment of a more ambitious Phase 4 carbon budget aligned with 2050 goals, and the introduction of mechanisms like a "heat exchanger" and a strategic demand-correction reserve to protect the system from future exogenous shocks.
