The US-Israel invasion of Iran in February 2026 has accelerated the global transition to clean energy as 23 countries announced new measures to reduce fossil fuel vulnerability. Clean energy ETFs have outperformed oil and gas ETFs in early May 2026, with renewable energy funds attracting over USD 3 billion in April 2026. Investor sentiment is shifting, with a rise in those ranking renewables top for one-year returns (14% vs 9% in 2025) and a decline in the perceived necessity of natural gas for the transition, particularly in Asia. While the cost of capital remains significantly higher in emerging markets (12.95%) compared to Europe (5.02%), geopolitical instability is prompting a reassessment of risk premiums in favor of domestic renewables.

The document argues that the EPA's 2026 proposed rule to weaken the Risk Management Program (RMP) is unlawful, arbitrary, and contrary to the Clean Air Act's mandate to prevent accidental chemical releases. The commenters contend that the proposal prioritizes industry cost savings and deregulatory executive orders over public health and safety, specifically threatening vulnerable populations and children. They call for the full implementation of the 2024 SCCAP Rule, the restoration of the RMP Public Data Tool, and the retention of critical safety requirements including safer technology analyses, third-party audits, and natural hazard planning.

The statement contends that Africa's reliance on fossil fuels leaves its communities vulnerable to external shocks, such as the economic ripple effects of the US-Iran war. It advocates for the implementation of existing frameworks like the African Single Electricity System and the African Union Green Minerals Strategy to achieve energy sovereignty and justice, arguing that transitioning to net-zero is more cost-effective than enduring the costs of global energy instability.

The Changing Markets Foundation argues that the EU's Vision 2040 for Fisheries and Aquaculture must address the structural unsustainability of carnivorous aquaculture. The organization highlights how the reliance on fishmeal and fish oil (FMFO) derived from wild fisheries increases pressure on marine ecosystems and undermines food security in regions such as West Africa, India, Vietnam, Peru, and Senegal. It advocates for a policy shift that prioritizes Low Trophic Aquaculture (LTA)—such as seaweed and bivalve farming—over carnivorous finfish production, while calling for the phasing out of marine ingredients in feed and improved transparency regarding total wild fish inputs in supply chains.

The US electric grid faces severe supply chain constraints, with lead times for large power transformers reaching up to four years and prices for power line cables doubling since 2019. Domestic production is insufficient, meeting only 20% of demand for large power transformers in 2025. To address this, the document proposes a three-pronged federal strategy: easing near-term bottlenecks through allied partnerships and production ramps; expanding domestic capacity via manufacturing tax credits and low-cost scaling capital; and promoting innovation in next-generation grid hardware. It also highlights subnational opportunities for states to attract investment through tailored workforce training and industrial clustering.

Environmental organizations oppose the 'year-round E15' bill, claiming it would increase greenhouse gas emissions through land-use changes, harm wildlife and water resources, and increase costs for consumers while primarily benefiting land investors.

The United States is well-positioned to lead the next-generation geothermal supply chain due to significant overlaps with the oil and gas industry, though gaps remain in superhot rock (SHR) compatible rigs and power conversion turbomachinery. While investment in the sector grew from $22 million in 2018 to $2.2 billion in 2025, the report warns that equipment supply chains could become a bottleneck for national-scale adoption. Developing a domestic supply chain could create over 100,000 jobs in wellfield and plant operations and catalyze manufacturing growth in regions like Louisiana, Texas, Oklahoma, Georgia, New York, North Carolina, and South Carolina. To secure this advantage, the report recommends expanding the 45X advanced manufacturing production tax credit to geothermal and improving data on equipment capacity and production costs.

The document proposes a shift toward 'imperfect agreements' to overcome deadlock in the WTO, suggesting that flexible, iterative, and often plurilateral arrangements can serve as stepping stones to formal law. It highlights various mechanisms, such as targeted trade deals, the use of GATS schedules for additional commitments, and interim agreements like the E-Commerce Agreement, as ways to maintain institutional relevance and implement sustainable development goals. The author contends that these dynamic approaches allow members to coordinate on urgent issues, such as digital trade and essential supplies, without waiting for full multilateral consensus.

The document highlights the health risks posed by extreme heat to players, workers, and fans during the 2026 World Cup, noting that cities like Monterrey, Dallas, and Miami could exceed 35 °C. It discusses FIFA's implementation of three-minute hydration breaks and the potential for shifting match structures to four quarters. Additionally, it addresses the environmental impact of the tournament, specifically the high pollution levels resulting from travel across three host countries, and links these temperature increases to the burning of fossil fuels.

The document explains that the El Niño-Southern Oscillation (ENSO) is a natural cycle of water temperature in the equatorial Pacific that drives global temperature and precipitation trends. It warns that a strong El Niño is likely by mid-summer 2026, which may boost global temperatures already elevated by human-caused climate change. The guide advises reporters to avoid storm-related terminology, consult local experts to understand regional 'teleconnections', and recognize that climate change is making ENSO swings more pronounced while ENSO simultaneously amplifies climate impacts like flooding and drought.

In April 2026, the United States experienced an average temperature anomaly of 3.4°F across 192 cities, with the Ohio Valley being the warmest region. The report highlights that 183 of the analyzed cities have shown long-term warming trends since 1970, with Reno, Nevada, seeing the greatest increase. Climate attribution analysis indicates that in San Juan, Puerto Rico, temperatures on 19 days in April were at least two times more likely due to climate change.

The statement contends that EPA Administrator Lee Zeldin has overseen a period of significant deregulation and funding cuts that undermine public health and environmental protection. It highlights the removal of human life valuation from air pollution analyses, the cancellation of $22 billion in environmental justice grants, and a 90 percent budget cut to the Clean Water State Revolving Fund despite PFAS reduction being listed as a priority. The author asserts that these actions, alongside the dismantling of the Office of Research and Development and a 52 percent overall budget cut, prioritize industry interests over scientific integrity and community health.

Leaders from GreenLatinos and other organizations advocate for the preservation of Latino, Chicano, Hispanic, and Indigenous histories within U.S. national parks and public lands. They condemn efforts to erase these narratives, remove Spanish-language resources, and dismantle environmental protections. The statement links the spirit of resistance associated with Cinco de Mayo to current struggles against climate change, inhumane migration policies, and the erasure of scientific truth and civil rights history in federal spaces.

Nineteen clean freight advocates are calling on members of the Truck & Engine Manufacturers Association (EMA) to withdraw support for the repeal of the U.S. EPA's Phase 3 greenhouse gas (GHG) emissions standards for medium- and heavy-duty vehicles. The authors argue that the EMA's decision to intervene in litigation to repeal these standards and the Endangerment Finding undermines public health, climate protections, and the U.S.'s ability to comply with the Paris Agreement. They claim that this regulatory instability hinders manufacturer investment and risks U.S. competitiveness against domestic competitors like Tesla and global competitors such as BYD. The letter suggests that companies should distance themselves from the EMA or withdraw membership to signal support for durable clean transportation policy.

The executive summary advocates for local 'behind-the-meter' solar and storage in Massachusetts as a means to protect environmental justice (EJ) communities from the health and financial burdens of gas-fired power plants and extreme weather. It notes that over 80 percent of the state's polluting power plants are located in or near EJ neighborhoods and proposes 18 recommendations to scale these clean energy solutions.

The Next-Generation Geothermal Research and Development Act (S.4406) aims to accelerate the commercialization of supercritical geothermal energy by expanding field testing, establishing targeted R&D, fostering public-private collaboration, and improving subsurface data access. The legislation expands the remit of the Frontier Observatory for Research in Geothermal Energy (FORGE) to include supercritical environments and creates a center of excellence to coordinate research across national labs and private stakeholders. It also mandates deep exploration boreholes and quadrennial reporting by the U.S. Geological Survey to map geothermal potential across diverse geological provinces in the U.S.

Mallory Stewart testifies that the U.S. must lead the development of international guardrails and rules of responsible behavior in outer space to avoid unintentional escalation and prevent China and Russia from defining future space security policy. Stewart emphasizes the need for the State Department to lead a unified space diplomacy policy, improve interagency coordination, and restart bilateral and multilateral space security dialogues to strengthen alliances and protect U.S. national security and commercial interests.

The authors argue that the Paris Climate Agreement's 'name and shame' approach fails because it ignores the science of cooperative agreements on common resources. They propose a climate club where members commit to net-zero CO2 emissions by 2050, using a combination of high import tariffs and export taxes on non-members, a uniform tariff surcharge (up to 10%) on non-member imports, and penalties for members who miss intermediate goals. To ensure WTO compatibility, the proposal relies on GATT Articles XX(b) and XX(g), allowing any regulatory approach that achieves emissions reductions. The plan includes a Multilateral Fund for developing countries and suggests similar structures for methane and nitrous oxide, drawing inspiration from the Montreal Protocol.

The report finds that methane emissions from anaerobic digestion (AD) systems typically range from 0.5% to 6% of total production, with some plants reaching 41%, which is significantly higher than average levels in the oil and gas industry. Current regulatory frameworks in countries like France and Germany often prioritize worker safety over methane mitigation, and the United States lacks dedicated federal or state regulations for AD methane emissions. The report emphasizes that digestate storage is frequently the largest emission source, particularly in the U.S. where lagoons are often uncovered. It recommends implementing robust, facility-level MMRV, mandatory leak detection and repair (LDAR) programs, and the use of conservatively high default emission factors in carbon crediting methodologies to incentivize actual emission reductions.

The document discusses induced seismicity in next-generation geothermal systems, specifically Enhanced Geothermal Systems (EGS), closed-loop systems, and superhot rock (SHR) geothermal. It identifies three primary triggers for seismicity in EGS: volume and pressure changes, temperature changes, and chemical changes. While closed-loop systems have lower risk, they may still induce seismicity through temperature-driven rock contraction. The text highlights historical failures in Basel, Switzerland (2006) and Pohang, South Korea (2017) as reasons for implementing modern mitigation protocols. Recommended safeguards include early geologic mapping, real-time seismic monitoring, and the adoption of regulatory frameworks such as the U.S. DOE's Induced Seismicity Protocol and Switzerland's Good-Practice Guide, which utilize 'traffic light systems' and GRID scores to manage risk based on geologic and social sensitivity.
