A joint statement from the Attorneys General of New York, Delaware, Maryland, Massachusetts, Oregon, Rhode Island, and Vermont urging the Environmental Protection Agency (EPA) to establish formal emission standards and guidelines for methane in the oil and gas sector following the publication of five technical white papers.

The report argues that sugar interests employ strategies similar to those of the tobacco industry to deceive the public and policymakers about the health risks of added sugar. It details tactics such as attacking scientific research, spreading misinformation through front groups, and using political contributions and lobbying to prevent the implementation of strict nutrition standards and sugar taxes. The document highlights the gap between actual American sugar consumption and recommended limits, while providing examples of local and international efforts to implement science-informed nutrition policies.

The document details SEI's multi-scale approach to climate mitigation, focusing on sub-national policy for cities, the necessity of limiting fossil-fuel infrastructure to meet the 2°C target, and the strategic use of modern bioenergy in developing countries. It highlights the use of the LEAP system for low-carbon planning and describes ongoing efforts to integrate social variables into technical climate analysis.

The report argues that feeding a projected global population of 9 billion by 2050 requires 'sustainable intensification'—producing more food with fewer resources to 'freeze the footprint of food'. Based on expert interviews, it identifies key opportunities in precision agriculture, soil health, genetics, and waste recovery. It highlights the US dairy industry as a potential leader in demonstrating closed-loop systems, particularly through the use of anaerobic digesters to convert manure into renewable energy. The document emphasizes that while incremental improvements are necessary, breakthroughs in technology and data sharing, supported by public and private investment, are essential for systemic change.

The report details how Illinois municipalities use Community Choice Aggregation (CCA) to pool electricity purchasing power, enabling them to negotiate lower rates and switch to cleaner energy sources. Since 2013, over 90 Illinois towns have transitioned to 100% renewable electricity via Renewable Energy Credits (RECs), increasing demand for wind and solar by over 6 terawatt hours. The document provides case studies from Oak Park and Chicago, analyzes CCA adoption in other states like California and Massachusetts, and offers strategic recommendations for municipalities to move beyond RECs toward local renewable energy investments.

The report identifies a significant range of estimated DPV values driven by differences in local context, input assumptions, and methodologies. While there is general agreement on estimating energy and capacity values, there is less consensus on grid support services and unmonetized values such as financial, security, environmental, and social risks. The analysis highlights that no single study comprehensively evaluated all DPV benefits and costs, and that costs associated with increased deployment are often inadequately assessed.

Earthjustice supports the nomination of Gina McCarthy to lead the EPA, citing her experience as a pragmatist and her work on clean car emissions and mercury pollution rules. The organization urges the new leadership to prioritize limits on industrial carbon pollution from power plants, finalize Clean Water Act jurisdiction policy, and establish safeguards for coal ash disposal.

The report identifies a critical gap between climate science outputs and the operational needs of transportation practitioners. It argues that adaptation requires not only improved climate data—such as updated precipitation atlases and sea-level rise projections—but also a deep understanding of local non-climate factors like infrastructure elevation and soil saturation. The document emphasizes the need for a 'central clearinghouse' of information, better 'Climate-to-English' translation of scientific terms, and the integration of climate risk into existing asset management and budgeting processes. It highlights various pilot projects and tools, including the FHWA Risk Assessment Model and Toronto's Climate Change Risk Assessment Tool, as pathways toward increasing the adaptive capacity of transportation systems.

The Clean Air Task Force supports the EPA's proposed new source performance standards (NSPS) for fossil-fueled power plants, which would limit emissions to 1,000 lbs. of CO2 per megawatt-hour. The author asserts that carbon capture and sequestration (CCS) technology is currently available and cost-effective, enabling new coal plants to meet or exceed these standards. The document highlights existing commercial CCS projects and the potential for the enhanced oil recovery (EOR) industry to create commercial demand for captured anthropogenic CO2, providing a hedge against future emissions if natural gas prices rise.

The report analyzes 15 significant safety-related 'near-misses' at U.S. nuclear plants in 2011, arguing that many resulted from owners tolerating known safety problems. While it highlights successful NRC interventions at the Fort Calhoun, Hatch, and LaSalle plants, it criticizes the agency for allowing 47 reactors to operate in violation of fire-protection regulations and 27 reactors to operate with deficient seismic protection. The author contends that the NRC often focuses on fixing individual equipment failures rather than addressing the systemic weaknesses in owners' testing and inspection regimes.

The report documents the presence of hexavalent chromium, a known carcinogen, in leachate from coal ash disposal sites and groundwater across the United States. It highlights a discrepancy between the EPA's recognition of the chemical's toxicity in drinking water and its failure to account for ingestion risks in its coal ash risk assessments. The document provides evidence from EPA, DOE, and EPRI studies showing that chromium leaching from coal ash is nearly 100% hexavalent and often exceeds safety standards by thousands of times. It concludes that the EPA must designate coal ash as a hazardous waste under the Resource Conservation and Recovery Act to protect public health.

The EPA has introduced new GHG permitting standards under the Clean Air Act, requiring large power plants and refineries to undergo a Best Available Control Technology (BACT) analysis. While states typically issue these permits, the EPA has taken over this role in Arizona and Texas due to non-compliance. The program targets facilities adding more than 75,000 tons of CO2 (or equivalent) and will expand in July 2011 to include all new facilities emitting over 100,000 tons per year. The BACT process involves a five-step evaluation of technology availability, feasibility, effectiveness, and impact to determine the best emission control options.

The document examines the technology and global status of offshore wind energy, noting that while Europe leads in operational capacity, the United States has significant untapped potential. It details the technical requirements for different water depths, the regulatory frameworks in countries like Denmark, and the specific siting and permitting complexities in the U.S. The text also addresses public concerns regarding tourism, wildlife, and military radar, while highlighting the economic benefits in terms of job creation and greenhouse gas reduction.

The Autodesk AEC Headquarters project serves as a demonstration of how BIM-enabled Integrated Project Delivery (IPD) can create radical process efficiencies. By utilizing a shared-risk and reward contract structure and a centralized 3-D building model, the project team—comprising Autodesk, KlingStubbins, and Tocci Building Corporation—aligned stakeholder interests and reduced traditional construction errors. Key outcomes included achieving LEED-CI Platinum certification, reducing lighting power density by 35% compared to standards, and completing the project under budget. The study concludes that while the project focused on process rather than radical resource efficiency, the IPD framework provides a scalable model for implementing complex, resource-efficient designs by reducing liability fears and improving interdisciplinary coordination.

The review concludes that the Manomet study likely underestimates the net carbon emissions of biomass energy due to overly optimistic assumptions regarding forest regrowth, soil carbon, and fuel sourcing. While the Manomet study suggests utility-scale biomass emissions are higher than coal and natural gas, the review argues that the perceived benefits for small-scale thermal and CHP plants are likely illusory. Key criticisms include the model's reliance on harvesting large trees to maximize regrowth, the omission of soil carbon losses, and the failure to account for indirect land-use effects such as firewood leakage.

The author advocates for a shift away from oil in the United States by implementing carbon or petroleum taxes to reduce demand and replacing petroleum-based fuels and materials with sustainable alternatives. The text highlights the potential for biofuels in transportation and heating, as well as the use of biomass for industrial chemicals and building products, emphasizing that such a transition must be grounded in sustainability to protect ecosystems.

In 2008, Massachusetts imported all the coal used by its power plants, primarily from Colombia, resulting in $252 million leaving the state economy. The state relies on coal for 24.5% of its in-state electricity generation despite having no domestic coal supplies. To reduce this dependence, Massachusetts has implemented aggressive energy efficiency targets, including a $1.7 billion investment from 2010 to 2012, and is expanding renewable energy through programs like Commonwealth Solar and the first US offshore wind facility in Nantucket Sound.

The World Resources Institute analysis finds that while existing federal and state tools can significantly reduce greenhouse gas emissions, even the most ambitious 'Go-Getter' scenario falls short of the U.S. Copenhagen pledge to reduce emissions 17 percent below 2005 levels by 2020. The report models three levels of regulatory ambition—Lackluster, Middle-of-the-Road, and Go-Getter—across key sectors including power plants, transportation, and industry. It concludes that additional legislative action is necessary to meet international climate targets and the long-term goal of 80 to 95 percent reductions by 2050.

The document outlines the job creation potential of the clean energy economy, citing that renewable energy (RE) and energy efficiency (EE) industries created over nine million jobs in the U.S. in 2007. It provides specific employment projections for various technologies, including wind, solar, bioenergy, and geothermal, across U.S. states and international markets such as Germany, Brazil, and India. The text also compares these figures to employment trends in the fossil fuel and nuclear sectors and details U.S. legislative efforts, such as the Green Jobs Act of 2007 and the American Recovery and Reinvestment Act of 2009, to support workforce training and clean energy deployment.

The briefing argues that municipal solid waste (MSW) is an underutilized renewable energy resource that can reduce greenhouse gas emissions and landfill reliance. It details five primary conversion technologies—landfill gas capture, combustion, pyrolysis, gasification, and plasma arc gasification—noting that while landfill gas is widely accepted, others face technical or regulatory hurdles. The text highlights that modern waste-to-energy facilities have significantly reduced toxic emissions and can complement recycling by recovering metals. However, it notes that MSW-to-energy receives substantially lower federal subsidies than other energy sources, which hinders commercial expansion.
