The provided text consists of appendices detailing an optimization model to assess the scalability of diversified crop rotations in Iowa, the potential for substituting corn with oats and alfalfa in livestock feed, and methodologies for calculating soil erosion and greenhouse gas emissions. It argues that longer rotation systems can maintain profitability while improving soil health and reducing pollution. The analysis includes specific scenarios for converting corn acreage in the most erodible counties and across the entire state, utilizing non-linear models to estimate nitrous oxide (N2O) reductions and carbon sequestration benefits.

The report analyzes the benefits of diversified crop rotations compared to the dominant corn-soybean system in the US Corn Belt, specifically focusing on Iowa. Based on research from Iowa State University's Marsden Farm, the authors find that three- and four-year rotations increase yields for corn and soybeans and maintain similar net profits while reducing herbicide and synthetic nitrogen fertilizer use. The report models the scalability of these systems, suggesting that implementing no-till diverse rotations on 3.6 million of Iowa's most erodible acres could reduce soil erosion by 91% and save taxpayers up to $198 million annually in water cleanup costs. It further suggests that up to 40% of Iowa's farmland could be converted to these systems if livestock feed markets adapt. To overcome financial, market, and technical barriers, the report recommends expanding USDA incentives, improving Whole Farm Revenue Protection insurance, and increasing funding for agroecological research.

The document evaluates Indonesia's transition from fixed fuel subsidies to market-aligned pricing, specifically for gasoline, diesel, and liquefied petroleum gas (LPG). It argues that while the 2015 reforms for gasoline and diesel saved approximately USD 15.6 billion, the system remains vulnerable to international price volatility. The brief proposes several price adjustment models—including smoothing, ratcheting, and cap-and-floor systems—to balance the government's need for fiscal sustainability with the necessity of protecting low-income consumers from sudden price spikes. It concludes with recommendations for a transparent, frequently updated pricing formula managed by an independent agency.

The analysis finds that high utility demand charges are a primary barrier to the profitability of public DCFC operators, sometimes accounting for over 90% of electricity costs. By modeling current usage data from 230 California stations across four future EV growth scenarios, the report demonstrates that proposed EV-specific tariffs from Southern California Edison (SCE) and San Diego Gas & Electric (SDG&E)—which reduce or eliminate demand charges—would significantly lower costs and enable a more sustainable business model. The authors argue for a shift toward time-varying volumetric rates and the socialization of some infrastructure costs to meet California's transportation electrification goals.

The study finds that at oil prices of $50 per barrel, U.S. government subsidies make nearly half of discovered, not-yet-producing oil fields profitable, potentially adding 20 billion barrels of production. This would result in approximately 8 billion tonnes of CO2 emissions, representing about 1% of the remaining global carbon budget to limit warming to 2°C. The analysis highlights that while subsidies significantly drive production at lower prices, they primarily function as transfers to industry profits at higher prices (e.g., $100 per barrel). The most impactful subsidy identified is the immediate expensing of intangible drilling costs (IDCs).

The report identifies significant opportunities for solar thermal energy in South Africa's agri-processing and textile sectors due to their need for heat below 160°C. It quantifies the potential installation area and greenhouse gas savings, while analyzing the financial drivers, such as rising energy prices, and barriers, including high capital costs and a lack of component-level certification. The document advocates for the use of Energy Service Companies (ESCOs) and government support to transition the 'infant' solar thermal industry toward cost-competitiveness.

The report introduces the Energy Access Dividend (EAD) framework to help policymakers quantify the benefits of rapid electrification. By analyzing Bangladesh, Ethiopia, and Kenya, it demonstrates that decentralized renewable energy can provide faster access than centralized grids, leading to significant household savings, increased study time for children, and reduced carbon and black carbon emissions. The model links these dividends to the achievement of multiple Sustainable Development Goals (SDGs), arguing that delays in energy access result in lost investments in human and economic development.

The document analyzes the impact of 'fast depreciation' and 'uplift' tax provisions on the profitability of over 700 licensed but non-producing oil and gas fields in Norway. It finds that these measures significantly increase the internal rate of return (IRR) for investors, making many fields economic that would otherwise be abandoned. At an oil price of USD 50 per barrel, the analysis suggests 95% of new oil investment depends on these supports, which could lead to an additional 8 billion barrels of production and 2.9 billion metric tonnes of CO2 emissions.

The Rocky Mountain Institute presents a business model for net zero energy (NZE) districts that achieves life-cycle cost neutrality compared to business-as-usual (BAU) developments. The model centers on an Integrated Energy Services Provider (IESP) that manages a micro-utility, district heating and cooling, and renewable energy deployment. By shifting capital costs for heating/cooling and solar PV away from parcel developers and providing on-bill financing for energy efficiency, the model reduces upfront costs for developers and lowers total energy bills for tenants. The approach includes outcome-based energy-performance requirements enforced through a system of incentives and penalties. A case study of a 180-acre mixed-use development in a midsize U.S. city demonstrates that the model remains economically favorable even under challenging conditions such as low electricity rates and a lack of net metering.

The study utilizes a high-resolution model of Israel's water supply to determine that current desalination capacity significantly exceeds optimal levels, even under climate-change-induced recharge declines. It further finds that the 'Balanced Budget Water Economy' legislation imposes a welfare cost exceeding USD 100 million annually due to the gap between average and marginal costs.

The report analyzes the reallocation of IDR 211 trillion (USD 15.6 billion) in fuel subsidy savings in Indonesia during 2015. It finds that funds were primarily redirected toward ministries' budgets, capital injections for state-owned enterprises (SOEs), and regional transfer funds. The study concludes that this shift from consumption to productive investment is aligned with the National Medium-Term Development Plan (RPJMN) 2015–2019, likely generating higher GDP and employment, and reducing the budget's vulnerability to international oil price volatility.

Massachusetts has become heavily reliant on natural gas for electricity, with it accounting for over 60 percent of in-state generation. This dependence exposes consumers to price volatility and hinders carbon reduction goals. The Union of Concerned Scientists proposes a diversified energy plan incorporating offshore and onshore wind, hydropower, and solar. This strategy could reduce natural gas use by 23 percent below business-as-usual by 2030, decrease carbon emissions by 6.6 million tons, and generate over $350 million in health and economic benefits in 2030, with a modest estimated increase in household electricity bills of approximately $3.00 per month.

The Union of Concerned Scientists proposes a "Clean Path Case" for Michigan to meet its Clean Power Plan (CPP) target of reducing CO2 emissions by 31 percent below 2012 levels by 2030. This pathway combines the CPP with strengthened renewable energy standards (RES) and energy efficiency resource standards (EERS). The analysis finds that this approach would result in 8,300 MW of new wind and solar capacity, $11.3 billion in clean energy investments, and $4.1 billion in public health and economic benefits by 2030. The report argues that this transition is cost-effective, with only a modest increase in average monthly household electricity bills (less than $3) compared to a scenario with no new policies.

The Union of Concerned Scientists proposes a "Clean Path Case" for New Mexico to meet its Clean Power Plan (CPP) target of reducing carbon dioxide emissions by 24 percent below 2012 levels by 2030. This pathway involves strengthening the state's renewable portfolio standard (RPS) and energy efficiency resource standard (EERS), alongside a mass-based carbon emissions trading program. The analysis indicates that this approach would diversify the electricity mix, reduce household electricity costs, and generate significant health and economic benefits.

The Union of Concerned Scientists analysis suggests that the Clean Power Plan (CPP) can reduce nationwide power plant carbon pollution by approximately 32 percent below 2005 levels by 2030. The proposed 'CPP National Trading Case' emphasizes a combination of wind, solar, and energy efficiency, supported by a national carbon emissions trading program. This approach is projected to generate $103 billion in public health and climate benefits through 2030 and create an average annual revenue of $17.8 billion from carbon allowance auctions between 2022 and 2030. While it may cause a modest near-term increase in household electricity bills, the analysis predicts net savings for consumers by 2030 due to lower operating costs of renewables and efficiency gains.

The Union of Concerned Scientists argues that Illinois can cost-effectively meet its Clean Power Plan (CPP) target—reducing carbon emissions by 34 percent below 2012 levels by 2030—by adopting a "Clean Path Case." This approach involves strengthening the state's renewable portfolio standard (RPS) and energy efficiency portfolio standard (EEPS) alongside a mass-based emissions trading program. The analysis suggests this pathway would yield nearly 6,000 MW of new wind and solar capacity, reduce typical household electricity costs by 9.4 percent by 2030, and generate $14.3 billion in cumulative health and economic benefits through 2030 by reducing CO2, SO2, and NOx pollution.

The Union of Concerned Scientists proposes a 'Clean Path Case' for Minnesota to meet its Clean Power Plan (CPP) target of reducing power sector emissions by 34 percent below 2012 levels by 2030. This pathway involves strengthening the state's Renewable Electricity Standard (RES) and Energy Efficiency Resource Standard (EERS), alongside a mass-based carbon emissions trading program. The analysis suggests this approach would yield over 4,500 MW of new wind and solar capacity, save the average household $54 annually by 2030, and generate $205 million in average annual revenue from carbon allowance sales between 2022 and 2030. Additionally, the plan is projected to provide $111 million in public health and economic benefits by reducing CO2, SO2, and NOx emissions.

The Union of Concerned Scientists proposes a "Clean Path Case" for Pennsylvania to meet its Clean Power Plan target of reducing emissions by 29 million tons (24% below 2012 levels) by 2030. This pathway combines a mass-based carbon emissions trading program with strengthened renewable energy and energy efficiency policies. The analysis indicates that this approach would yield over 10,700 MW of new wind and solar capacity, generate $804 million in average annual revenue from carbon allowance auctions, and provide $4.5 billion in cumulative health and economic benefits through 2030. Long-term, the plan is projected to reduce typical residential electricity bills by 3.4% by 2030 compared to a reference case with no new policies.

The Union of Concerned Scientists proposes a "Clean Path" for Virginia to comply with the Clean Power Plan by transitioning from voluntary to mandatory renewable energy and energy efficiency targets and implementing a mass-based carbon emissions-trading program. The analysis suggests this approach would reduce CO2 emissions by 77 million tons through 2030 compared to a reference case, lower typical residential electricity bills by 5% by 2030, and generate an average of $241 million in annual auction revenue for state investments. The report highlights Virginia's current underutilization of its renewable potential, noting that non-hydro renewables accounted for only 2.8% of electricity generation in 2014.

The document analyzes the climate impact of phasing out federal fossil fuel leases in the U.S. It finds that while current policies project an 11% increase in production by 2040, a 2°C pathway requires a 40–60% reduction. Ceasing new federal leases could reduce global CO2 emissions by approximately 100 million tonnes per year by 2030, primarily through reduced coal and offshore oil production.
