Schwarzenegger and Newsom Reunite to Celebrate California's 20-Year Climate Law in Long Beach

For the first time in years, Arnold Schwarzenegger and Gov. Gavin Newsom occupied the same stage in Long Beach on Wednesday, building a unified case for AB 32 — California's landmark climate law — even as the redistricting outcome that ended their most direct political confrontation continues to shape the state's electoral map ahead of November.

A Rare Stage, a Calculated Message

Held October 13–15 in Long Beach, the 2026 California Economic Summit provided the backdrop for a conversation as strategically calculated as it was substantive. In a format the program billed as a "fireside chat," Schwarzenegger and Newsom sat together to mark the twentieth anniversary of AB 32, the California Global Warming Solutions Act, before an audience of regional business, government, and civic leaders. The optics carried their own message: a Republican environmental legacy-holder and a Democrat with clear national ambitions, openly sharing credit for a law that still drives sharp ideological disagreement nationwide.

The Signing That Started It All

On September 27, 2006, Schwarzenegger signed AB 32 at a ceremony on Treasure Island in San Francisco — putting into law a statewide emissions cap that no state had previously attempted. The statute directed California to bring its greenhouse gas output back to 1990 levels by 2020. Newsom, then serving as San Francisco's mayor, attended that original event and returned to Long Beach on Wednesday to argue the law's momentum is still building.

Schwarzenegger on the Early Critics: Blunt as Ever

The 79-year-old former governor offered no softened account of the opponents who fought AB 32 at its passage. Reflecting on the fierce industry resistance that greeted the legislation in 2006, Schwarzenegger defended California's carbon market and argued that rigorous environmental oversight and sustained economic growth had reinforced each other — precisely the inversion his critics once claimed was impossible.

"We have shown to the world what a subnational government, a state, can do," Schwarzenegger said, pointing to documented emissions reductions and continued business investment as proof that regulatory certainty draws capital into a market rather than driving it out.

His deeper argument rested on a reframing of conventional economic logic: that clear, durable environmental rules give investors the long-horizon certainty they need to commit. California reinforced that architecture in September 2025, when the state legislature approved a 15-year extension of cap-and-invest, locking the AB 32 framework in through 2045 — well beyond any single administration in Washington.

Newsom's $16 Billion Case — and His Critique of Federal Policy

Newsom arrived with figures. He credited AB 32 with generating California's cap-and-invest program and said the state has directed approximately $16 billion in auction revenues toward consumer energy-cost relief since the program launched, with another $8 billion projected over the next four years. He pointed to accelerating investment in renewable energy and battery storage as evidence that California's climate policy has built a technology-industrial base, not merely an environmental record.

"We're proving the genius of 'and' versus the tyranny of 'or,'" Newsom said, framing California as living proof that economic growth and aggressive climate policy can reinforce rather than undermine each other. He also noted that he has been coordinating with governments across the U.S. and internationally to fill the gap left by the federal government's withdrawal from climate leadership.

The Economists Who Aren't Celebrating

Not everyone in the room shared that framing. Wayne Winegarden, a senior fellow at the Pacific Research Institute, challenged the celebratory narrative, arguing that the policy discussion rarely accounts for the significantly higher energy bills Californians pay as a direct consequence of the state's regulatory model — costs that are, he contended, consistently undercounted in assessments of AB 32's legacy.

Winegarden's core challenge targeted the economic causation itself: he argued that California's leadership is taking credit for growth rooted in long-standing structural advantages — Silicon Valley's dominance chief among them — rather than in current policy choices, and cautioned that innovation clusters in Austin and the Research Triangle in North Carolina are quietly closing the state's technological gap.

"People are leaving California on net. So are many businesses," Winegarden said. Persistent domestic outmigration and a wave of notable corporate relocations give that critique a weight that Wednesday's proceedings did not directly engage.

The Fracture That Climate Cannot Bridge

The bipartisan display had a well-documented limit. In 2025, Newsom championed Proposition 50, a ballot measure to temporarily set aside California's independent redistricting commission and authorize Democratic legislators to draw new congressional maps targeting five Republican-held seats — framed explicitly as a counter to Republican redistricting pushed by President Trump in Texas.

Schwarzenegger condemned the plan and led the "No" campaign against it. The 79-year-old had invested years building the redistricting commission through two constitutional ballot measures — Prop 11 in 2008, which created the nonpartisan body for state legislative maps, and Prop 20 in 2010, which extended its reach to congressional districts. His spokesman said Schwarzenegger considers gerrymandering "truly evil" regardless of which party pursues it.

Despite that opposition, Proposition 50 passed on November 4, 2025, with roughly 65 percent of the vote. The new Democratic-drawn congressional maps are in use for the 2026 midterm elections; the independent commission's authority over congressional districts will not return until after the 2030 census. Republican donor and physicist Charles Munger Jr. — the most significant financial backer of California's redistricting commission over the years — bankrolled the opposition, which was outspent and defeated. Multiple legal challenges to Prop 50 have been turned back by state and federal courts.

California's Model, Under the Spotlight

Wednesday's summit captured something genuine about California's political character: two governors who share real common ground on climate but diverge sharply on how the state's democratic institutions should be structured. The AB 32 anniversary provides both men a platform to claim twenty years of vindication and to frame the next chapter on their own terms.

Whether California's regulatory model becomes a blueprint for a fragmented national energy landscape, or a cautionary tale about costs that outlast their architects, is the question the state's economy will spend the next decade answering.
