The report outlines various in-lake remediation strategies to combat eutrophication in Manitoba's prairie lakes, emphasizing that these treatments should complement efforts to control external nutrient sources. It details three biological methods (biomanipulation, floating treatment wetlands, and macrophyte removal), five physical/engineering methods (hypolimnetic withdrawal, dilution/flushing, hypolimnetic aeration, artificial circulation, and dredging), and three chemical methods (phosphorus inactivation, sediment oxidation, and algicides), providing their benefits, shortfalls, suitable lake conditions, and associated costs.

The survey found that approximately 43-44% of households in California and the Northeast are technically suitable for current plug-in hybrid electric vehicles (PHEVs) based on parking, hauling, and passenger needs. Consumer interest in EVs is higher in California, where 54.63% are likely to consider one for their next vehicle, compared to 34.86% in the Northeast. The most cited barrier to ownership is the purchase price, and the most desired policy is a tax credit or rebate. While there is strong agreement that EVs reduce climate emissions, awareness of specific government and utility incentives remains low.

The policy brief asserts that global climate success depends on the 20 largest emitting nations adopting a small set of high-impact policies across four sectors: electricity, buildings, industry, and transportation. It emphasizes that policy design is critical to avoid inefficiencies and suggests the use of 'Best Practice Networks' (BPNs) to provide technical expertise to governments to ensure these policies are effectively implemented.

The paper argues that traditional cost-of-service regulation incentivizes utilities to invest in capital expenditures to meet peak demand. To counter this, it proposes a PIM based on an outcome-oriented metric—specifically the percentage reduction in peak load—rather than a measure-by-measure counterfactual approach, which it claims failed in California's Risk Reward Incentive Mechanism (RRIM). The author recommends setting long-term targets (five to eight years) with annual interim goals and utilizing a sloped, symmetrical incentive structure with upper and lower caps. To manage risk, the proposal suggests a gradual implementation starting with small revenue amounts, eventually scaling the PIM based on independent studies of the net societal benefits of peak reduction.

The document examines the $6.8 billion merger between Exelon and Pepco, focusing on the contentious approval process in Washington, D.C. It uses this case to highlight five industry trends: increased utility consolidation to hedge against low wholesale power prices, disputes over microgrid ownership, the criticality of rate design equity, the rise of empowered local customer constituencies, and the proliferation of state-level power sector transformation proceedings.

CIEL President Carroll Muffett supports the collaboration of US state Attorneys General in investigating fossil fuel companies for climate deception, noting that five jurisdictions—New York, California, Maryland, Massachusetts, and the US Virgin Islands—have confirmed investigations into Exxon.

The briefing provides a historical analysis of nuclear waste siting in the United States, asserting that the Department of Energy (DOE) has consistently failed to secure long-term consent for high-level waste (HLW) and spent nuclear fuel (SNF) repositories. The author highlights a pattern of broken promises, litigation, and the failure of both the Nuclear Waste Policy Act (NWPA) and the 'volunteer' process managed by the Nuclear Waste Negotiator. Key examples include the legal battles over the Waste Isolation Pilot Plant (WIPP) and the non-consent of the Nevada state government regarding Yucca Mountain. The document concludes that the DOE's lack of reliability makes it unlikely that future consent agreements for consolidated storage or repositories will be trusted or successful.

The document provides a comprehensive overview of offshore wind energy as of early 2016, contrasting the advanced capacity in Europe with the nascent industry in the United States. It details the technical advantages of offshore wind over onshore wind, such as stronger and more consistent winds and proximity to coastal population centers. The text outlines U.S. government initiatives, including Department of Energy funding and Bureau of Ocean Energy Management leasing, while highlighting the United Kingdom, Germany, and Denmark as global leaders. It also discusses the economic impact of the sector, specifically the 'additional employment effect' in European ports and shipyards.

The report examines 'water balance' goals, where companies aim to restore a volume of water equivalent to what they consume. While these goals provide clear communication and incentive for action, the document argues that they must be grounded in local basin contexts and collective action to avoid 'greenwashing' and effectively mitigate physical, regulatory, and reputational risks. It highlights the transition toward 'context-based targets' aligned with Sustainable Development Goal 6.

This briefing outlines the Climate Policy Initiative's (CPI) framework for evaluating the efficiency of public financial interventions, such as green banks, in supporting the transition to a low-carbon economy. It focuses on identifying financial barriers and determining the most effective risk-bearing mechanisms and implementing institutions to address them.

The report outlines a systematic approach to identifying and addressing financial barriers to low-carbon investment. It proposes an analysis matrix that intersects various financial stakeholders with specific barriers—such as high cost of capital, perceived risk, and split incentives—to determine where public intervention is most effective. The authors argue that dedicated institutions like green banks can be advantageous by co-housing policies to allow for flexible funding, creating a 'brain trust' of expertise, and simplifying access for consumers. The document also provides a table of existing public green infrastructure banks in the OECD, including examples from Australia, the UK, Korea, Canada, and the USA.

The RMI Community Energy Resource Guide offers a structured process for local governments to transition to clean energy. It outlines a 6-to-12-month planning cycle involving stakeholder collaboration, data baselining, and the selection of sector-specific tactics. The guide details strategies across four primary domains: buildings, electricity supply, transportation, and industry, while emphasizing the role of 'broad enablers' like Green Banks and updated utility regulatory models to scale implementation.

The briefing challenges the notion that variable renewables will limit their own growth by depressing wholesale electricity prices. It contends that these concerns rely on static models of the grid and ignore the synergistic effects of complementary supply resources, flexible demand-side responses, and the decreasing cost of storage. By shifting from incremental to whole-system thinking and updating 20th-century market designs, the author asserts that wind and solar can continue to expand without facing practical economic limits.

The document provides a comprehensive overview of 'green jobs' in the US and internationally, highlighting the growth of sectors like solar, wind, and energy efficiency. It notes that the US Bureau of Labor Statistics ceased its Green Careers program in 2013, leading to a reliance on fragmented data from multiple sources. Globally, the International Renewable Energy Agency (IRENA) identifies China as the leader in renewable energy employment, with solar PV being the largest global employer in the sector.

Fuel cells generate electricity through a chemical reaction between oxygen and hydrogen, offering a high-efficiency, low-emission alternative to combustion engines and batteries. While they excel in reliability, scalability, and energy density, widespread adoption is hindered by high costs—particularly the need for platinum in PEM cells—and the lack of hydrogen fueling infrastructure. Applications range from portable electronics and stationary power (including combined heat and power systems) to transportation. In the U.S., the Department of Energy and various state-level policies, such as Renewable Portfolio Standards and tax credits, are working to reduce system costs and expand infrastructure to make fuel cells more competitive with gasoline-powered vehicles.

The document provides a comprehensive overview of clean energy employment, highlighting the U.S. and global landscapes. In the U.S., it details job figures across energy efficiency (buildings, appliances, transport) and renewable energy (solar, wind, biofuels, geothermal, hydro, and waste-to-energy). Globally, it identifies China as the leader in renewable energy employment, followed by Brazil, the U.S., India, and Germany, with solar PV being the largest employment driver worldwide.

The document argues that urban GHG mitigation is most effective when governments at different levels operate according to their comparative advantages. It categorizes city roles into policy leaders, critical implementers, and strategic partners, mapping these roles to specific abatement potentials in transport, buildings, and waste. The authors emphasize that national governments must provide enabling actions—specifically financial support, technical capacity, and policy alignment—to unlock this potential. Case studies of China, the United States, and Brazil illustrate varying degrees of vertical integration and identify specific national-level gaps that hinder city-scale climate action.

The Union of Concerned Scientists proposes a green bank for Michigan, estimating that an initial public investment of $105 million could leverage $3.3 billion in total clean energy investments by 2030. This financial mechanism would support the deployment of 685 MW of solar capacity and reduce annual carbon dioxide emissions by 3.9 million tons, contributing 13% of the emissions reductions required for the state to meet Clean Power Plan targets. The document outlines various financial products the bank could offer, such as credit enhancements and warehousing, and identifies existing Michigan programs that could be integrated into this structure.

The Union of Concerned Scientists analyzes how a hypothetical Pennsylvania green bank, with an initial $135 million capitalization, could leverage $4.2 billion in total investment by 2030. This initiative would support 780 MW of wind and solar capacity, save $375 million annually on electricity bills, and reduce CO2 emissions by 4.8 million tons per year, contributing 11% of the state's required reductions under the Clean Power Plan.

The Union of Concerned Scientists analyzes how a hypothetical Virginia green bank with $90 million in initial capitalization could leverage $2.8 billion in total investment by 2030, significantly reducing carbon emissions and supporting the deployment of 575 MW of wind and solar capacity.
