The document details the costs and benefits of three technology pathways—fuel efficiency, electrification, and low-carbon fuels—for New Jersey. It projects that by 2050, a total investment of nearly $122 billion will generate over $171 billion in returns, resulting in a cumulative net benefit of almost $50 billion. These transitions are expected to reduce carbon dioxide emissions by 353.6 million metric tons and save nearly 37 billion gallons of fossil-based liquid fuels by 2050.

The document details the financial and environmental impacts of transitioning to clean transportation in New York. It estimates that by 2050, cumulative investments of nearly $218 billion in electrification, efficiency, and low-carbon fuels will yield a net benefit of $80.5 billion, primarily driven by fuel savings and avoided environmental costs.

The Union of Concerned Scientists reports that investing in fuel efficiency, vehicle electrification, and low-carbon fuels in Pennsylvania would result in a cumulative net benefit of over $60 billion by 2050. The analysis indicates that while electricity generation and storage represent the largest investment cost, these are offset by significant fuel savings and avoided environmental and health costs. By 2050, these measures would avoid 515.4 million metric tons of carbon dioxide and reduce fossil-based liquid fuel use by 52.5 billion gallons.

The document details the costs and benefits of transitioning to clean transportation in Virginia by 2050. It estimates that a total investment of $142.5 billion in electrification, fuel efficiency, and low-carbon fuels will generate a cumulative net benefit of nearly $57 billion, primarily driven by fuel savings and avoided environmental costs, while reducing CO2 emissions by 412.1 million metric tons.

The document details the economic and environmental impact of transitioning to clean transportation in Vermont. It estimates that a total investment of $13.4 billion by 2050 will result in a cumulative net benefit of $4.5 billion, driven primarily by fuel savings and avoided environmental costs, while significantly reducing carbon dioxide emissions.

India can integrate 390GW of wind and solar generation by 2030 at a lower total system cost than its current trajectory by increasing the flexibility of electricity supply and demand. The report identifies four primary flexibility needs: operating reserves, ramping, daily balancing, and seasonal balancing, all of which will grow as renewable energy penetration increases. A 'balanced portfolio' combining demand-side management, energy storage, and powerplant flexibility is found to be the most cost-effective approach, reducing energy waste by 82% to 97%, total system costs by 5% to 8%, and carbon emissions by 8% to 12% compared to a thermal-only approach. Regional analysis reveals that states like Tamil Nadu and Karnataka will face acute seasonal and ramping challenges, while Uttar Pradesh could act as a flexibility exporter due to its industrial base. The report concludes that urgent action on data, market design, and infrastructure is required to unlock these flexibility resources.

The report evaluates green economy (GE) investments in Georgia, focusing on buildings, agriculture, and tourism. Using the SAVi methodology, it demonstrates that while traditional financial analysis suggests these investments may not be profitable, incorporating environmental, social, and economic externalities reveals a high sustainable internal rate of return (S-IRR) of 84% and a sustainable net present value (S-NPV) of approximately GEL 20.4 billion.

The report finds that the incremental cost of building ZER homes is modest, averaging 1.8%, while ZE homes average a 7.3% premium. These costs often fall below consumer willingness-to-pay and mortgage-savings thresholds. The analysis identifies heat pumps, LED lighting, and ENERGY STAR appliances as cost-optimal measures and projects that ZE incremental costs will drop to 3.1%–5.5% by 2030 due to declining solar PV costs and efficiency gains. It emphasizes the need for skilled labor training and supportive policy frameworks to accelerate adoption across various US climate zones.

The report evaluates multiple conservation scenarios for Lake Dal, concluding that a hybrid approach combining grey infrastructure (sewage treatment plants), solar PV power, and natural infrastructure (artificial wetlands) is the most cost-effective way to prevent ecological collapse and maximize economic benefits from tourism and fisheries.

The document consists of a series of data tables (Appendix F) detailing the financial and environmental impacts of transportation decarbonization across several US states. It tracks costs such as incremental vehicle costs and charging infrastructure against benefits like gasoline and diesel fuel savings, as well as monetized greenhouse gas (GHG), NOx, and PM2.5 reductions. The data is split between 'MID' and 'HIGH' scenarios for each state, projecting outcomes through 2050.

The report analyzes the regressive nature of the 2018 VAT increase in South Africa, which reduced disposable income for poor households. It evaluates existing zero-rating as generally effective and proposes 23 new categories for zero-rating—including baby food, school uniforms, and public medical services—to support vulnerable groups, particularly female-headed households. The report estimates that while expanding zero-rating would cost R17bn in revenue, a 25% luxury VAT rate on high-end goods could recover approximately R9.6bn of that loss.

The study finds that new coal-fired power plants are not necessary to meet South Africa's electricity demand at the lowest cost and that committing to the Thabametsi and Khanyisa IPPs would substantially increase both system costs and greenhouse gas emissions. Using the South African Times Model (SATIM), the authors demonstrate that a least-cost build plan relies on wind, solar PV, and gas, while the coal IPPs would create a generation surplus and potentially accelerate Eskom's financial crisis. The report highlights that the emissions from these plants would almost entirely offset the savings from the National Energy Efficiency Strategy or the expected reductions from the carbon tax.

The research identifies that simple SLM practices like manuring and intercropping provide high benefit-to-cost ratios and positive net present value through 2030, whereas high-cost practices like terraces and agroforestry have lower ratios and longer break-even periods. The study recommends prioritising simple practices in policy while using subsidies and economic measures to support high-cost practices that offer broader societal benefits.

Scaling up 10 existing climate solutions in Estonia, Latvia, Lithuania, Poland, and Ukraine could reduce 2030 emissions by approximately 149 Mt (CO2e), representing a 13% reduction compared to baseline projections. The most significant absolute reductions are possible in Poland (71 Mt) and Ukraine (64 Mt), while the highest relative impacts are in the Baltic States, potentially cutting emissions by nearly 40% in Estonia and over 30% in Latvia and Lithuania. Energy efficiency in buildings and industry offers the highest potential and is the most cost-effective, with building efficiency alone potentially saving 2.9 billion euros by 2030. Conversely, wind power provides the greatest relative potential in the Baltic States. The report identifies common barriers such as high investment costs, weak carbon pricing, and lack of financing, and recommends policies including the phase-out of fossil fuel subsidies, stable legal frameworks, and targeted financial incentives.

The report argues that Eskom is facing a liquidity and financial crisis driven by stagnant electricity demand and the high costs of its coal-fired power construction programme. Through system-level modelling and station-specific analysis, the study finds that the levelised costs of operating older coal stations (Arnot, Camden, Grootvlei, Hendrina, and Komati) exceed their system alternative value, meaning they can be replaced by cheaper alternatives without compromising security of supply. Specifically, decommissioning Grootvlei, Hendrina, and Komati early could save Eskom R12.5bn in present value terms. Additionally, the report finds that cancelling Kusile units 5 and 6 is economically viable if capital cost savings exceed a threshold of approximately R4.7bn. The authors conclude that South Africa no longer requires new nuclear, coal, or gas procurement, as solar PV and wind have become the most competitive new-build options.

The report uses the Long-range Energy Alternatives Planning (LEAP) system to model Jamaica's GHG emissions and assess various mitigation actions across energy, waste, and agriculture sectors. It finds that while baseline emissions are projected to increase by 58% by 2055, significant low-cost abatement is possible, potentially allowing Jamaica to exceed its NDC targets without additional direct social costs. The analysis also highlights gender-differentiated impacts and identifies financial and technical capacity needs, particularly in domestic mitigation modeling and renewable energy implementation.

The document analyzes the inefficiencies of India's Public Distribution System (PDS) for kerosene, noting high rates of leakage and poor targeting. It argues that current subsidies make solar lighting less cost-competitive for households, particularly for mid- and high-end systems. The authors recommend streamlining eligibility, phasing out subsidies in electrified areas, and redirecting funds toward a 'lighting subsidy' for solar solutions.

The report analyzes GHG mitigation in Azerbaijan, Kazakhstan, and Uzbekistan, finding that while these countries have high GHG intensity due to fossil fuel reliance, significant low-cost abatement is possible through energy efficiency and fuel switching. It proposes specific Nationally Appropriate Mitigation Actions (NAMAs) and investment concepts for each country to transition toward low-carbon growth.

The report identifies a set of 21 cost-effective and technically feasible policies that can enable Mexico to meet its 2030 climate goals. It proposes two scenarios: an unconditional package to reduce GHG emissions by 22% below the baseline and a conditional package for a 36% reduction. The analysis indicates that Mexico can achieve these targets while realizing significant net financial savings and public health benefits through reduced particulate matter pollution. The proposed eight-point action plan prioritizes industrial efficiency, methane capture, and carbon pricing as the most impactful interventions.

The P50 Risk Solutions instrument aims to transfer weather-related volume risk from banks to the insurance market by providing a minimum revenue guarantee for wind power projects. The goal is to reduce financing costs and attract new capital sources by improving the P90 generation levels used by banks for credit assessments. However, the report concludes that the instrument is not commercially viable for standalone projects or portfolios, as the cost of insurance outweighs the potential reductions in financing costs. Furthermore, it finds that the instrument is unlikely to attract institutional investors because the risk of delayed payments from state distribution companies (DISCOMs) is perceived as far more significant than wind variability risk. Regulatory hurdles regarding cross-border reinsurance and a lack of market demand led the original proponents, Swiss Re and P50 Risk Managers, to abandon the project in India.
