The Union of Concerned Scientists reports that the EPA's January 25, 2018, withdrawal of the "once in, always in" (OIAI) policy allows industrial facilities to be reclassified from "major sources" to "area sources" of hazardous air pollutants (HAPs). This reclassification removes the requirement for facilities to use Maximum Achievable Control Technology (MACT), which the authors estimate was used by 70 percent of major sources in 2014 to keep emissions at or below thresholds of 10 or 25 tons per year. The document warns that area sources are not regulated or inspected as stringently, potentially increasing emissions of toxic substances like chlorine, benzene, and styrene. The analysis identifies at least 21 states at risk of increased pollution, with specific high-risk clusters in Louisiana's "Cancer Alley," Houston, Chicago, and the New York-Newark urban area.

The guide encourages people to overcome the 'spiral' of silence regarding climate change by engaging in interpersonal conversations. It suggests using a combination of scientific data on extreme weather, personal narratives of climate impacts, and economic arguments regarding the competitiveness and job-creation potential of clean energy to persuade others.

The document argues that federal light-duty vehicle standards set by the EPA and NHTSA in 2012 provide significant financial and environmental advantages to Connecticut. By 2030, the average Connecticut household is projected to be $2,750 richer due to gas savings, and the state has already saved $380 million. Environmentally, the standards eliminate global warming emissions in Connecticut equivalent to twice those required to provide electricity to Hartford. The report also links these standards to broader national gains, including an expected increase in GDP by up to $30 billion and the creation of 650,000 full-time jobs by 2030.

Amory B. Lovins of RMI argues that subsidies for distressed nuclear plants are unjustified because closing high-cost nuclear units and reinvesting their operating expenses into energy efficiency can reduce more carbon than maintaining the plants. He contends that 'baseload' power is not a grid requirement and that variable renewables are more resilient and cost-effective than central thermal plants.

The report argues that California's carpet stewardship program, led by the industry-controlled Carpet America Recovery Effort (CARE), has failed to meet recycling goals and instead increased the incineration of carpet waste. It contends that incineration—including Waste-to-Energy (WTE), cement kilns, and Carpet as Alternative Fuel (CAAF)—is a wasteful practice that violates the California Public Resources Code's waste management hierarchy. The document highlights significant environmental and health risks, noting that burning carpets containing PVC releases dioxins and unregulated nanoparticles. Financially, it claims WTE is the most expensive energy generation method in the U.S. and can lead to municipal bankruptcy. From a climate perspective, it cites CalRecycle data showing that WTE incineration adds approximately 26,000 metric tons of CO2, whereas recycling saves about 36,000 metric tons. The authors recommend that CalRecycle reject CARE as the stewardship organization and mandate an industry-funded program with enforceable recycling targets.

The report addresses the conflict between the Northeastern U.S.'s aggressive renewable energy targets and its limited available land. It argues that meeting these goals requires a combination of innovative siting on low-conflict lands (such as brownfields and prison lands), the acceleration of offshore wind, the use of distributed energy resources, and the import of Canadian hydroelectricity. The authors emphasize that overcoming local opposition through early community engagement and 'Smart from the Start' principles is critical to avoiding project delays and failures.

The document analyzes the U.S. home energy financing landscape, distinguishing between traditional lenders (e.g., FHA, Fannie Mae) and nontraditional options (e.g., PACE, on-bill financing). It argues that consumer choice is driven more by the timing of improvements and ease of origination than by interest rates or terms. Key barriers include manual underwriting for traditional products and a lack of standardization and securitization for nontraditional products. The brief recommends automating underwriting for traditional lenders and creating standardized, poolable programs for nontraditional financing to enable scaling.

The U.S. carpet industry is characterized by high waste, with 89% of discarded carpets ending up in landfills and 6% being incinerated. Despite the existence of the Carpet America Recovery Effort (CARE), only 1% of carpet waste is recycled back into carpet in a closed loop. The report argues that major manufacturers, particularly Shaw and Mohawk, engage in greenwashing and actively lobby against Extended Producer Responsibility (EPR) legislation to maintain a wasteful linear model. In California, the AB 2398 law has failed to achieve meaningful recycling increases because it relies on consumer fees rather than producer funding, and is administered by CARE, which the report claims is under the influence of the industry's largest players.

The document details a spreadsheet model designed to quantify the effects of hypothetical green banks in Maine, New Hampshire, and Vermont from 2017 to 2031. It outlines the financial assumptions, including initial capitalization based on New York's per-capita rates, a 5% borrower interest rate, and a 5:1 private-sector leverage ratio. The methodology explains how funds are allocated across energy efficiency, solar photovoltaics, and community wind, and how these investments are translated into installed capacity, electricity savings, and avoided carbon emissions using data from NREL, ACEEE, and the EPA.

The Union of Concerned Scientists proposes that Maine establish a green bank to catalyze private-sector investment in clean energy. An analysis suggests that an initial public capitalization of $14 million could leverage $300 million in total investment over 15 years. This initiative would support 70 MW of new solar and wind capacity, save homes and businesses $33 million annually on electricity bills through efficiency, and reduce carbon dioxide emissions by nearly 176,000 tons by 2031. The document identifies Efficiency Maine, the Finance Authority of Maine, and the Maine Technology Institute as potential hosts for the bank and outlines financial tools such as credit enhancements, warehousing, and direct lending to drive market transformation.

The Union of Concerned Scientists proposes that New Hampshire establish a clean energy finance authority to leverage public funds for private investment. An analysis suggests that an initial $14 million capitalization could drive $300 million in total investment over 15 years, resulting in 70 MW of new solar and wind capacity, $40.3 million in annual electricity bill savings, and a reduction of 222,900 tons of carbon dioxide emissions by 2031.

The Union of Concerned Scientists (UCS) proposes that Vermont could leverage an initial $7 million public investment into $148 million of total clean energy investment over 15 years. This expanded financing capacity would support nearly 50 MW of new solar and wind power, save homes and businesses $14.6 million annually on electricity bills, and reduce carbon dioxide emissions by over 111,500 tons by 2031. The report details existing Vermont programs—such as Efficiency Vermont, PACE financing, and the Clean Energy Development Fund—and suggests a more comprehensive, coordinated public-private financing initiative to meet the state's long-term goal of 90% renewable energy and efficiency by 2050.

The document advocates for increasing electric vehicle (EV) availability in the Northeast and Mid-Atlantic, noting that while 55% of regional consumers are interested, availability lags significantly behind California. It calls for the expiration of a regulatory exemption that allows sales in California to count toward compliance in Northeast states and suggests updating ZEV program credits to account for rapid improvements in battery range.

The National Program for fuel efficiency and emissions standards is a cornerstone of Connecticut's strategy to reduce transportation emissions, which account for 40 percent of the state's total. The Union of Concerned Scientists estimates that the program has already saved Connecticut drivers $324 million since 2011 and reduced oil consumption by 97 million gallons. By 2030, the program is projected to lower the state's global warming emissions by 4.5 million metric tons per year, save consumers $1.5 billion in gas expenses, and create over 4,000 jobs, increasing the state's GDP by more than $1 billion.

The report analyzes the US electric vehicle (EV) market as of 2016, finding that while cumulative sales were nearing 500,000, progress among automakers is uneven. BMW, General Motors, Nissan, and Tesla are identified as leaders, while Honda, Toyota, and Fiat Chrysler are characterized as laggards. A significant disparity in vehicle availability exists between California and the rest of the US, largely attributed to California's Zero Emission Vehicle (ZEV) program. The authors argue that limited model availability and poor dealership inventory outside California hinder the national transition to electric transportation.

The National Program for fuel efficiency and emissions standards is critical for the Northeast, where passenger vehicles account for over 25% of regional emissions. The program has already reduced oil consumption by 1.3 billion gallons since 2011 and is projected to lower global warming pollution by 75 million metric tons per year by 2030. Economically, it is estimated to save the average Northeast household over $2,400 annually by 2030 and create more than 125,000 regional jobs.

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.

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.
