The document evaluates the EIPC's Carbon Reduction Scenario, which aims to reduce carbon emissions in the Eastern Interconnection by 42% below 2005 levels by 2030. Analysis by Synapse Energy Economics indicates that this scenario achieves these reductions with cumulative ratepayer costs through 2040 nearly identical to a 'Business-as-Usual' approach. The scenario relies on a combination of wind energy, energy efficiency, and expanded interregional transmission, specifically projecting 103 GW of new wind in MISO states to support the broader region. The report argues that regional cooperation and updated, lower costs for wind and solar make these targets highly achievable and potentially 30% cheaper than business-as-usual when carbon costs are valued uniformly.

The document outlines a supplemental analysis by the American Council for an Energy Efficient Economy (ACEEE) to quantify the impact of nine energy efficiency policies across residential, commercial, and industrial sectors. By 2030, these policies are projected to achieve cumulative end-use energy savings of 12.1 quadrillion BTUs, representing a 29 percent reduction in projected energy consumption compared to a reference case. The analysis estimates that annual policy costs will rise from $7.5 billion in 2020 to $13.4 billion in 2030, stimulating private investment of $113.6 billion by 2030. Key policies include federal appliance standards, an Energy Efficiency Resource Standard (EERS) for electricity and natural gas, updated building codes, and expanded R&D. The modeling utilizes the Energy Information Administration's NEMS model to determine effects on electricity generation, carbon dioxide emissions, and energy prices.

The Union of Concerned Scientists analysis finds that California's cleaner fuels and vehicle policies—including cap and trade, the low carbon fuel standard, and vehicle standards—will reduce ownership costs for drivers. Weekly savings for new vehicle owners are projected to increase from $3.90 for a 2015 model to $8.98 for a 2025 model compared to a 2008 baseline. A 10-year-old used car purchased in 2025 is estimated to save its driver $7.46 per week compared to a similar used car purchased in 2015.

The analysis finds that financial incentives and charging station deployment would yield net-positive benefits in Ho Chi Minh City during early EV adoption, with a benefit-cost ratio between 1.69 and 1.86 over eight years.

The document introduces a cost-benefit analysis (CBA) tool designed to evaluate the financial feasibility of solar irrigation pumps (SIPs) in Rajasthan. By utilizing metrics such as net present value (NPV), internal rate of return (IRR), benefit-to-cost ratio, and payback period, the tool aims to demonstrate the monetary benefits for farmers, DISCOMs, and the state government. The transition to SIPs is intended to reduce the state's heavy electricity subsidies for agriculture, lower carbon footprints by avoiding power procurement, and provide farmers with additional income through feeding excess electricity back into the grid.

The analysis finds that pursuing a net zero emissions pathway by 2050 in Ethiopia would increase the average real annual GDP growth rate by 1.4 percent relative to a business-as-usual scenario. While the NZE pathway requires an additional US$66.98 billion in cumulative investment costs by 2050, it is projected to generate $111 billion in cumulative co-benefits through increased real GDP and avoid $89 billion in costs, primarily in energy. Social co-benefits include an average of 672,000 additional green jobs and significant increases in disposable incomes (10.5 percent by 2030 and 53.1 percent by 2050). The benefit-cost ratio for investments in mitigation and adaptation is estimated to rise from 1.04 in 2030 to 2.99 by 2050.
