The Union of Concerned Scientists analyzed 50 U.S. states to identify those at high risk of natural gas overreliance in the power sector. The analysis uses five metrics: the share of in-state electricity production from natural gas in 2014, the increase in that share from 2008 to 2014, the share of new capacity being built from natural gas (2014–2017), total projected natural gas capacity in 2017, and 2013 power sector carbon dioxide emissions. The report highlights that excessive reliance on natural gas exposes ratepayers to fuel price volatility and the risk of 'stranded assets' from infrastructure that may become underused or abandoned. It also notes that a shift from coal to gas is insufficient for long-term climate goals due to continued significant emissions upon combustion.

The report defines climate exposure as potential portfolio gains or losses due to climate change, categorized into policy, physical, and market exposures. It analyzes the role of Environmental, Social, and Governance (ESG) data as the primary information source for investors, while highlighting significant limitations in data quality and the prevalence of voluntary disclosure. The document evaluates various management tools, including ESG data aggregators and financial products such as exclusionary, non-exclusionary, and thematic indexes, as well as green bonds and YieldCos. It concludes that current tools are skewed toward risk mitigation rather than opportunity identification and recommends mandatory standardized disclosure to improve comparability and effectiveness.

The report examines the systemic risk posed by credit rating agencies' failure to account for climate change in their methodologies. It argues that by assuming a 'business-as-usual' scenario of $\ge 4^{\circ}C$ warming rather than a dynamic trajectory aligned with a $2^{\circ}C$ goal, agencies are artificially inflating the credit ratings of fossil fuel projects. Using a case study of the Adani Abbot Point Terminal in Australia, the document demonstrates how generic project finance methodologies ignore risks such as stranded assets, decreased coal demand, and physical climate impacts. The report concludes that this failure not only threatens global financial stability by creating a 'carbon bubble' but also exposes rating agencies to significant legal liability under the Dodd-Frank Act and common law.

The analysis finds that grid-connected solar-plus-battery systems will become the lowest-cost option for many customers within 10-15 years, potentially causing massive revenue losses for utilities. In the Northeast U.S. alone, potential residential and commercial kWh sales erosion by 2030 could reach 58 million MWh and 83 million MWh respectively. The report argues that eliminating net metering or adding fixed charges only delays this outcome. To avoid a future of stranded assets and high costs for non-adopters, the authors advocate for an 'integrated grid' featuring locational and temporal pricing, performance-based regulation, and the monetization of distributed energy resource (DER) values.

The analysis finds that grid-connected solar-plus-battery systems will rapidly become cost-effective, potentially leading to significant load defection that could undermine utility revenues and create stranded assets. The report argues that the electricity system is at a 'fork in the road,' where current regulatory and pricing models will either lead to fragmented grid defection or an integrated grid where distributed energy resources (DERs) provide value back to the system.

The report examines the transition of the U.S. power sector from coal to natural gas, noting that while this shift provides immediate benefits, it introduces risks such as price volatility, methane leakage, and potential 'stranded assets'. Using the National Energy Modeling System, the analysis compares a 'Business as Usual' scenario with a 'Carbon Standard plus Renewables and Efficiency Policies' scenario. The findings suggest that the latter would reduce power plant carbon emissions by 70 percent below 2005 levels by 2040, lower consumer energy bills, and provide significant net societal benefits, reaching nearly $170 billion by 2040.

The report examines the transition of the U.S. power sector from coal to natural gas, highlighting that while this shift provides immediate reductions in some pollutants, it creates long-term risks including price volatility, methane leakage, and stranded assets. Through modeling three scenarios—Business as Usual, a Carbon Standard, and a Carbon Standard plus Renewables and Efficiency Policies—the authors find that a diversified energy mix is the most economically and environmentally sound approach. The 'Carbon Standard plus Renewables and Efficiency Policies' scenario is projected to reduce power plant carbon emissions by 70% below 2005 levels by 2040 and generate net societal benefits of nearly $170 billion by that year. The report recommends strengthening the EPA's Clean Power Plan, implementing federal renewable electricity and energy efficiency standards, and increasing regulations on fugitive methane emissions.

The Center for International Environmental Law (CIEL) argues that the Norwegian Government Pension Fund Global (GPFG) faces significant legal, financial, and reputational risks due to its investments in fossil fuel companies. CIEL highlights that GPFG invests in 44 of the 90 'Carbon Majors' responsible for 63% of industrial greenhouse gas emissions from 1854-2010, increasing the likelihood of successful climate change litigation. The document specifically calls for immediate divestment from coal, citing the industry's financial decline, systemic demand drops in the US, and severe environmental and human rights abuses in India and China. Furthermore, CIEL asserts that continued fossil fuel investment contradicts Norway's international obligations under the UN Framework Convention on Climate Change and its commitment to inter-generational equity.

The report argues that transitioning to a low-carbon economy can increase global financial capacity rather than deplete it. For the electricity sector, the transition could provide a net benefit of $1.8 trillion by 2035, as significant operating savings from avoided fossil fuel extraction and transport outweigh higher capital costs and stranded assets. In the transport sector, the impact is more policy-dependent, ranging from a $2.5 trillion cost to a $3.5 trillion benefit, depending on whether the transition is driven by taxes or innovation. The authors emphasize that reducing the cost of capital for low-carbon infrastructure through regulatory and financial reforms is critical to maximizing these benefits.

The report estimates that a transition to a low-carbon economy could put nearly $25 trillion of fossil fuel asset value at risk, with approximately 80% of this risk borne by governments rather than private investors. The analysis highlights that oil represents the majority of value at risk (close to 75%), while coal offers the highest emissions reduction potential with relatively low stranding risk (12%). The document argues that the net economic impact depends heavily on policy: a purely tax-based approach to reducing oil demand could cost the global economy $3 trillion, whereas an innovation-led transition could yield a net benefit of $7 trillion. It recommends prioritizing the phase-out of coal and utilizing financial mechanisms to lower the cost of renewable energy in emerging markets.

The Green Economy Coalition (GEC) argues that while the green economy narrative is gaining traction, it requires a shift toward moral and economic storytelling, local 'heroes', and systemic financial reform to become mainstream. The document identifies key narrative 'storylines'—such as economic revival, community empowerment, and financial crisis—and emphasizes that emerging economies are currently adopting these frameworks more enthusiastically than developed nations. It specifically calls for the reform of central banks and monetary policy to address systemic risks like 'stranded assets' and 'carbon bubbles', suggesting that civil society must lead this change to overcome political apathy in the North.

The author contends that energy efficiency is a disruptive technology that, through 'integrative design,' can provide energy services more cheaply than supply-side production. By optimizing entire systems rather than individual components, the author claims significant reductions in energy use are possible in buildings, industrial processes, and transport. A central focus is placed on the automotive sector, where 'ultralighting' and electrification could realistically eliminate US motor-fuel demand by 2050. The text warns that oil and gas companies face existential risks as demand-side innovations make hydrocarbons uncompetitive, suggesting these firms pivot toward efficiency and renewable energy investments.

The report examines how the transition to a low-carbon economy creates 'stranded assets'—assets that suffer premature write-downs or devaluation due to climate change, regulation, or technological shifts. It highlights that traditional market valuations often ignore long-term carbon budgets, leading to overinvestment in fossil fuels. The author provides specific risk assessments from HSBC, noting that 40-60% of the market value of major European oil and gas companies is at risk. To mitigate these risks, the document proposes reforms in capital regulation for high-carbon industries, fiscal incentives for sustainable investment, financial regulation that accounts for climate stability, and the adoption of climate targets by institutional investors.

The document examines how the global shift toward a low-carbon economy creates the risk of 'stranded assets'—productive assets that suffer premature write-offs or downward revaluations. It highlights that current market valuations often ignore long-term carbon targets, leading to overinvestment in fossil fuels. Using HSBC analysis, the report quantifies potential value losses in the coal and oil and gas sectors, while also noting the impact of water stress on China's energy sector. It concludes by recommending four themes for capital market alignment: capital stewardship in high-carbon sectors, linking financial incentives to ESG factors, climate-proofing financial regulation, and setting portfolio climate targets for institutional investors.

The document argues that a gap exists between the capital required for a sustainable transition and actual private sector investment due to market and policy failures. It identifies 'short-termism' as a systemic bias in the investment industry that leads to the undervaluation of long-term sustainability risks and opportunities. To counter this, the report proposes a policy framework based on three elements: enabling open and competitive markets through fiscal incentives and transparency, addressing internal industry disincentives such as short-term remuneration structures, and providing transitional support through de-risking mechanisms and the alignment of public pension funds. It highlights various international case studies, including the UK's Green Investment Bank and the EU's Financial Transactions Tax, to illustrate how regulatory intervention can shift the risk-reward balance toward low-carbon investments.

The report argues that while real-economy policies are essential, they are insufficient to catalyze the scale of green finance needed for a sustainable transition. It examines China's progress in green credit, insurance, and emissions trading, while highlighting the need for a comprehensive framework of definitions, standards, and regulatory mandates to avoid systemic risks like stranded assets. The authors suggest that emerging economies, particularly China, have an opportunity to 'leapfrog' developed markets by integrating sustainability into the core design of their maturing financial systems.

The document examines the concept of 'unburnable carbon' and the risk of 'lock-in' where new fossil fuel infrastructure commits societies to high-emission pathways. It highlights a gap in green growth planning, which typically focuses on demand-side efficiency rather than supply-side extraction limits. The authors argue that without widespread carbon capture and storage (CCS), a 2°C warming limit will require leaving the majority of coal and unconventional oil reserves in the ground, potentially creating a 'carbon bubble' of overvalued assets.

The report finds that while South African institutional investors increasingly recognize the relevance of ESG factors, integration remains slow and inconsistent. Many investors rely on narrow proxies for climate risk, such as carbon taxes, while largely ignoring physical risks and water scarcity. The study highlights a systemic lack of demand from asset owners and a prevalence of short-termism in performance evaluation, which hinders the transition to a low-carbon economy. Despite these barriers, a majority of respondents acknowledge that portfolios are heavily exposed to climate-vulnerable sectors, particularly through state-owned enterprises like Eskom and Transnet, leading to the conclusion that many assets may be mispriced.

The document argues that current climate policies focus too heavily on the demand side, allowing fossil fuel exporting countries to increase production with little impact on their own territorial emissions accounts. It proposes 'extraction-based emissions accounting', which attributes CO2 emissions to the country where fuels are extracted, as a way to promote producer responsibility and identify economic vulnerabilities. The brief notes that countries heavily dependent on high-carbon exports face risks of 'stranded' assets if global demand declines, as projected in some IEA scenarios. Additionally, it suggests integrating life-cycle assessments (LCA) to account for varying upstream emissions, such as those from Canadian oil sands, which can be significantly higher than conventional crude.

The report argues that South African institutional investors, as 'universal owners', face material financial risks from climate change and water scarcity, which are currently underpriced in securities markets. It highlights that listed coal reserves exceed scientific carbon budgets and that water scarcity poses significant operational risks to water-intensive sectors. The document recommends a shift toward low-carbon and water-responsible investments, calling for regulatory interventions to create investment-grade green financial products and mandatory ESG disclosures to avoid stranded assets and systemic market shocks.
