The research evaluates the impact of a tiered pricing drought plan implemented by the El Dorado Irrigation District (EID) using a discrete continuous choice (DCC) model within a water evaluation and planning (WEAP) framework. The analysis finds that the drought plan significantly reduces consumer welfare loss compared to a scenario with no plan, as current consumption levels exceed essential needs. The study also examines non-monetary performance metrics, including reservoir storage and hydropower generation, concluding that the EID bears most of the plan's costs through reduced revenues.

The document highlights a trend of increasingly destructive wildfires in the U.S., driven by climate change and a lack of funding for hazardous fuel reduction. It notes that forests are shifting from carbon sinks to emitters and that the U.S. Forest Service faces significant budget cuts despite rising fire risks. The author proposes that developing markets for woody biomass and bioenergy could provide a sustainable funding mechanism for forest restoration and wildfire prevention.

The report analyzes the shift in California's residential solar market from purchasing to leasing, where leased systems grew from less than 10% of new installations in 2007 to over 75% in 2012. It finds that leasing reduces consumer barriers by eliminating up-front costs and simplifying complex processes, and that declining state incentives (CSI) helped lower prices and reduce the cost of federal tax incentives to taxpayers.

The document analyzes President Obama's 2013 climate strategy, which shifts toward EPA sector-regulation for electricity due to congressional inaction on carbon pricing. It compares this approach to Canada's regulations, examines the potential for continental equivalency in emissions trading, and discusses the plan's impact on the Keystone XL Pipeline and international climate negotiations.

The report argues that the EU ETS has failed to drive domestic emissions reductions due to a cap set against inflated projections and a flood of low-quality offsets. It finds that the system is now cancelling out approximately 700 million tonnes of abatement from other EU policies. The author recommends the permanent removal of 1.7 billion allowances from Phase 3 auctions to restore environmental integrity and increase Europe's 2020 climate target to 30% below 1990 levels.

The 'Half the Oil' plan proposes reducing U.S. oil use by 50% over 20 years, projecting annual oil spending cuts of $550 billion, the creation of over 1 million jobs, and the elimination of 2 billion metric tons of global warming emissions per year by 2035. The strategy focuses on improving fuel efficiency for passenger vehicles and heavy-duty trucks, expanding the adoption of electric vehicles (EVs), and implementing 'smart growth' urban planning to reduce vehicle miles traveled.

Carbon Market Watch argues that existing carbon markets have collapsed due to oversupply and poor quality, specifically citing the CDM and JI. The briefing recommends strengthening additionality criteria, shortening crediting periods, and establishing mandatory human rights and sustainability safeguards. For new mechanisms like the FVA and NMM, it advocates for a binding international governance structure and a common transaction tracking mechanism to prevent double counting of emission reductions.

The document examines the barriers California K-12 school districts face when implementing energy efficiency projects, such as budget pressures and a lack of technical expertise. It argues that Proposition 39 funds, estimated at $2.75 billion over five years, should be used to target deep energy-saving projects that districts cannot afford independently, rather than funding low-cost retrofits that are already economical. The author recommends providing non-commercial technical assistance to help districts vet proposals and suggests a tiered funding approach based on a district's specific financial capacity and access to existing loans or bonds.

The document examines how Proposition 39, which provides an estimated $2.75 billion for energy efficiency and clean energy in public buildings, can be targeted to maximize energy savings in California schools. It identifies that while many districts can access low-cost private capital for short-payback projects like lighting, they lack the technical capacity to vet proposals and the funding to pursue deeper, more costly energy-saving measures. The authors recommend using Proposition 39 funds for impartial technical assistance, matching grants for high-impact projects, and targeted support for financially distressed or small districts.

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 policy brief analyzes four regulatory scenarios for Canada's oil and gas sector, pairing emission-intensity improvements (20% to 40%) with price ceilings ($20 to $60). It argues that a 40% intensity standard with a two-tiered price ceiling ($30 and $60) provides an optimal balance by delivering 42 megatonnes of compliance in 2020 at an average cost of $28 per tonne. The author notes that while higher intensity targets increase costs, the average cost per barrel remains low (under $1), suggesting that such regulations would not significantly deter industry investment, as project hurdle rates already account for a $40 marginal cost.

The report argues that state renewable electricity standards (RES) are effective market-based tools that have driven significant growth in wind and solar capacity across the U.S. with minimal cost impacts on consumers. It highlights that these policies stimulate local economies through job creation in installation and manufacturing, provide new revenue streams for rural landowners, and stabilize electricity rates by removing reliance on volatile fossil fuel markets. While noting strong compliance rates, the document identifies transmission infrastructure, market oversupplies, and political opposition as primary challenges to further expansion.

Landfills are the third largest source of anthropogenic methane in the U.S., contributing 17.7 percent of all U.S. methane emissions. The EPA regulates large municipal solid waste landfills through the Clean Air Act and RCRA, while the voluntary Landfill Methane Outreach Program (LMOP) facilitates the development of energy projects. As of October 2012, 605 operational energy projects exist across 48 states, producing 15 billion kWh of electricity and 100 billion cubic feet of gas for direct use annually. The economic viability of these projects depends heavily on whether capture systems are already in place; for example, a 3 MW turbine project with an existing system can yield a net return of $590,000 over 15 years, whereas one without a system may lose $3.5 million without additional tax credits or carbon offsets.

The authors used the Water Evaluation And Planning (WEAP) system to simulate hydropower generation in the upper west slope Sierra Nevada under four temperature increase scenarios (0°C, 2°C, 4°C, and 6°C) through 2100. The model indicates that the highly productive northern Sierra Nevada would experience large reductions in hydropower generation due to decreased annual runoff, while central watersheds show a better ability to adapt to changes in runoff timing. Generation in the less productive southern watersheds also decreases.

The report analyzes building energy efficiency across China, Germany, and the United States, identifying four primary policy intervention points: new construction, building retrofits, equipment, and operations. It highlights how different national contexts—such as China's rapid urbanization, Germany's aging building stock, and the U.S.'s high per capita energy use—necessitate distinct policy priorities. The document details specific barriers to efficiency, such as split incentives and high upfront costs, and reviews the current policy landscapes and research efforts of the Climate Policy Initiative in these regions.

The report examines how carbon pricing mechanisms—such as carbon taxes and emissions trading systems—affect the competitiveness of the mining and metals sector. It focuses on aluminium, copper, iron ore, and coal across the EU, South Africa, Australia, Canada, and the US. The analysis highlights that electricity-intensive processes, like aluminium smelting, are most vulnerable to indirect costs passed through from power grids. The report advocates for a principles-based approach to policy design to prevent carbon leakage and maintain international competitiveness, recommending a transition toward a harmonized global emissions system.

The document argues that Ontario should implement a unified carbon-pricing scheme, specifically a cap-and-trade system, to preempt federal sector-by-sector regulations and ensure cost-effective mitigation. Using economic modelling, the authors suggest that full compliance flexibility—including offsets and potential linking with the Western Climate Initiative (WCI)—could reduce compliance costs to below $15 per tonne by 2020. The brief cautions against overcompensating firms through free permit allocations, particularly in the electricity sector, to avoid windfall profits, and suggests a 25,000 tonne coverage threshold to align with California and Quebec systems.

The document explains that global sea level has risen approximately eight inches since the Industrial Revolution, driven primarily by thermal expansion and the melting of land ice due to global warming. It highlights that the U.S. East and Gulf coasts are experiencing some of the world's fastest rates of rise. Projections for 2100 range from 8 inches to 6.6 feet, with significant risks of permanent inundation, amplified storm surges, and shoreline erosion for over 100 million Americans living in coastal counties. The report argues that while adaptation is necessary, reducing heat-trapping emissions is the most effective way to limit the pace and magnitude of future sea level rise.

The report examines the growth of wind and solar power in the U.S. and globally, asserting that the technical challenges of variable energy sources are manageable. It highlights successful integration by utilities like Xcel Energy and countries like Denmark and Germany. The document details various tools for maintaining reliability—including geographic dispersion, improved forecasting, transmission upgrades, and energy storage—and cites studies suggesting that renewables could provide 80% of U.S. electricity by 2050.

The document details the environmental footprint of geothermal power, distinguishing between hydrothermal and enhanced geothermal systems. It highlights that while closed-loop systems minimize air emissions and water contamination, open-loop systems release gases like hydrogen sulfide and carbon dioxide. The text notes that geothermal energy has significantly lower life-cycle global warming emissions than coal or natural gas, though it can be associated with land subsidence and increased earthquake frequency.
