The UK and California governments signed a memorandum of understanding to deepen cooperation on clean energy, climate action, nature protection, and resilience to extreme weather, aiming to boost transatlantic investment, foster collaboration between research institutions, help clean energy businesses access the California market, and share expertise.

The agreement is expected to open export opportunities, create skilled jobs, and help British businesses compete and grow, with examples like Octopus Energy expanding on the US West Coast.

UK Energy Secretary Ed Miliband framed the accord as a path to lower bills, more jobs, and climate progress through stronger international partnerships and investment for the UK.

Trump criticized the deal and Governor Newsom, using derogatory nicknames and arguing it was inappropriate for the UK to engage with him, while claiming California’s environmental policies have failed.

The former president contrasted federal climate action with California’s state-led initiatives and suggested implications for cross-border cooperation if the UK partners with Newsom.

Trump’s remarks included questioning cross-border agreements and labeling Newsom with a derogatory nickname, arguing the UK should not engage with him.

The deal stands independently of the UK’s broader energy policy alignment with the Trump administration, which has been less cooperative on climate action.

The broader climate policy backdrop shows the federal administration signaling less aggressive climate action, while California leads green policies and multilateral cooperation, with nuclear energy remaining a focus in UK-Trump discussions.

Tensions persist between the UK government and the Trump administration on energy policy, including ongoing promotion of nuclear energy as part of strategic cooperation.

The agreement is positioned separately from the US federal stance on climate action amid tensions over policy and fossil fuel support, while Newsom pursues state-level green policies and international engagement.

California Governor Newsom touted the state as a premier destination for clean-energy investment, noting significant clean tech investment from Octopus Energy part of the partnership.

Newsom highlighted California’s leadership in green policy, welcoming nearly a billion dollars in clean tech investment from Octopus Energy and referencing the Octopus Shift app supporting grid services with Southern California Edison.
