# California-UK Energy Deal Sets Stage for Federal-State Showdown

Current Situation

A new fault line in American climate politics has emerged following California Governor Gavin Newsom's signing of a clean energy Memorandum of Understanding (MoU) with the United Kingdom on February 16, 2026. The agreement, formalized with UK Energy Secretary Ed Miliband in London, aims to deepen cooperation on offshore wind, clean energy technologies, and climate initiatives between California and Britain (Article 1). Within hours, President Donald Trump denounced the deal as "inappropriate," calling Newsom "a loser" and questioning Britain's judgment in engaging with the California governor (Articles 2, 3, 4). The MoU is designed to strengthen transatlantic investment, support jobs in both economies, and connect British clean energy firms with California's massive market. According to Article 1, it builds on similar agreements the UK has signed with 11 other U.S. states, including Washington and Florida. The deal specifically focuses on offshore wind development—a technology Trump has publicly derided as being for "losers" (Article 5).

Key Trends and Signals

Several critical patterns emerge from this confrontation: **1. Escalating Federal-State Tensions on Foreign Engagement** Trump's characterization of the agreement as "inappropriate" suggests he views state-level international climate agreements as encroaching on federal foreign policy prerogatives. This represents a potential escalation beyond typical partisan disputes over environmental policy into questions of constitutional authority. **2. Personal Political Dynamics** Article 3 notes that Newsom is "an outspoken Trump critic" who has "publicly considered seeking the Democratic presidential nomination in 2028." This personal rivalry transforms what might otherwise be routine state diplomacy into a proxy battle for 2028 presidential positioning. **3. International Willingness to Work Around Federal Policy** The UK's decision to formalize agreements with multiple U.S. states (12 total, according to Article 1) indicates that foreign governments are actively building sub-national partnerships to maintain climate cooperation regardless of federal policy direction. **4. California's Growing Climate Diplomacy** Newsom's spokesperson responded aggressively to Trump's criticism, stating that "Donald Trump is on his knees for coal and Big Oil, selling out America's future to China" (Article 3). This combative response signals California's intention to continue independent climate diplomacy.

Predictions

### 1. Legal and Constitutional Challenge (High Probability, 1-3 Months) The Trump administration is likely to explore legal mechanisms to challenge or constrain state-level international agreements. While the MoU is non-binding, the administration may: - Issue formal guidance from the State Department discouraging foreign governments from signing agreements with U.S. states - Invoke the dormant foreign affairs doctrine or argue violations of the Compact Clause (which prohibits states from entering agreements with foreign powers without congressional consent) - Pressure the UK government through diplomatic channels to suspend or limit cooperation The reasoning: Trump's use of the specific term "inappropriate" suggests legal review is already underway. His administration has shown willingness to challenge California on multiple fronts, from auto emissions standards to immigration policy. ### 2. Expansion of State Climate Coalitions (High Probability, 2-4 Months) Rather than retreating, California and like-minded states will likely form more explicit coalitions for international climate engagement. We should expect: - Coordinated multi-state delegations to COP summits and international climate forums - Joint state agreements with other nations, particularly EU members - Creation of formal working groups among U.S. states to present unified positions The reasoning: The UK has already signed agreements with 11 other states, creating a ready-made coalition. Newsom's defiant response and his 2028 ambitions give him strong incentives to position himself as leading resistance to Trump's energy policies. ### 3. British Government Caught in Diplomatic Crossfire (Medium-High Probability, 2-6 Weeks) The UK government will face pressure to clarify its position and may attempt to quietly de-escalate while maintaining the agreement. Expect: - UK officials emphasizing that similar agreements exist with multiple states and predate current tensions - Attempts to avoid high-profile implementation that could further antagonize Trump - Possible behind-the-scenes assurances to the White House while maintaining public support for the agreement The reasoning: Britain needs strong relations with the federal government for trade, defense, and broader diplomatic purposes. Article 2 quotes Trump saying "The U.K.'s got enough trouble without getting involved with Gavin Newscum," which may be interpreted as a veiled threat. ### 4. This Becomes a Template for Future Conflicts (High Probability, Ongoing) The California-UK agreement will establish precedents for how states navigate international cooperation during periods of federal opposition. This suggests: - More states will pursue direct international partnerships on climate, trade, and technology - Other policy areas (immigration, AI regulation, data privacy) may see similar state-level international engagement - Increasing normalization of parallel diplomatic tracks The reasoning: California's economy alone would rank as the world's fifth-largest if it were a country. Other large states like New York, Texas, and Florida have similar incentives to pursue their interests internationally. ### 5. 2028 Presidential Campaign Impacts (High Probability, Ongoing through 2028) This confrontation will become a recurring theme in Newsom's likely presidential campaign. Expect: - Newsom to highlight international partnerships as evidence of leadership and Trump's isolation - Trump (or his successor) to use this as evidence of Democratic disloyalty and constitutional overreach - The broader question of state vs. federal authority on climate becoming a key campaign issue The reasoning: Article 3 explicitly notes Newsom's 2028 presidential considerations. His spokesperson's aggressive response about Trump being "on his knees for coal and Big Oil" shows this is already being framed in campaign terms.

Conclusion

The California-UK clean energy agreement represents more than a routine climate cooperation pact. It has become a test case for the limits of state authority in foreign engagement, a preview of 2028 presidential politics, and a signal that international climate cooperation will continue through sub-national channels regardless of federal policy. The most significant outcome may not be the agreement's direct impact on clean energy deployment, but rather the precedent it sets for how states, nations, and non-state actors navigate a fragmented U.S. approach to global challenges. As climate, technology, and economic policy become increasingly interconnected with international relations, the constitutional and political questions raised by this dispute will only intensify. Stakeholders should watch for formal legal challenges, the UK's diplomatic maneuvering, and whether other nations follow Britain's example in formalizing state-level partnerships.
