California Advances in Emissions Reductions as Renewable Energy Gains Momentum
SAN FRANCISCO — California is making strides in reducing its carbon footprint, achieving a 3% drop in climate pollution in 2023. This marks one of the state’s largest annual reductions, following significant declines during the Great Recession and the COVID-19 pandemic. The latest data from the 17th annual California Green Innovation Index by think tank Next 10 highlights this progress, indicating that while the state is not yet on track to meet its 2030 climate goals, the gap is closing.
F. Noel Perry, Founder of Next 10, comments, “California is making significant progress reducing greenhouse gas emissions, with huge reductions coming from the electricity sector.” He notes the dual achievement of California becoming the world’s fourth-largest economy while reducing emissions, reinforcing that economic growth and climate action are not mutually exclusive.
From 2022 to 2023, per capita greenhouse gas emissions in California dropped by 2.8%, while inflation-adjusted GDP per capita rose by 2.3%. This trend showcases the possibility of aligning economic growth with climate ambition, as evidenced by substantial reductions in heavy-duty vehicle emissions alongside economic expansion.
Renewable Energy Surpasses Fossil Fuels
California’s focus on renewable energy is yielding results, with solar, wind, and battery storage investments boosting clean power generation. For the first time, over half of California’s energy (52.3%) in 2024 came from renewable sources and large hydroelectric power. Conversely, fossil fuel’s share of the power mix fell to a record low of 36.3%, a 4.8% reduction over three years.
The state saw a 4.4% increase in non-hydropower renewable energy generation from 2023 to 2024, marking the largest recorded rise. Meeting the target of 50% non-hydro renewables by 2026 seems feasible if this growth continues.
Stephanie Leonard, Research Director at Next 10, states, “California has continued to deploy renewable energy and phased down its gas generation, delivering real emissions reductions.” She remains optimistic that with continued policy support, California can meet its bold climate targets.
Decline in Transportation Emissions
Transportation, contributing 38% to the state’s total emissions in 2023, witnessed a significant 4.6% emissions reduction from 2022 to 2023. Heavy-duty vehicles led this decline with a 17% reduction, while emissions per vehicle mile traveled reached a historic low.
F. Noel Perry expresses concern about future progress, citing the potential impacts of removing the EV tax credit and challenges to California’s emissions standards. However, he remains hopeful due to the substantial reductions achieved through existing regulations.
Key Observations
- Since the introduction of greenhouse gas reduction targets in 2016, California’s emission reductions have nearly doubled compared to the previous decade.
- While all sectors have cut emissions since 2006, commercial and residential sectors saw increases due to higher-emitting substitutes in refrigeration and air conditioning.
- To meet the 2045 goal of reducing emissions by 85% below 1990 levels, California must double its current annual reduction rate post-2030.
Progress in Transportation and Energy Efficiency
- Significant reductions in transportation emissions were achieved, primarily through cleaner fuels and increased zero-emission vehicle (ZEV) adoption.
- ZEV registrations surged by 25.3% in 2024, yet continued growth is essential to meet the 5 million ZEVs target by 2030, especially after the repeal of EV tax credits.
- Despite high electricity costs, California’s energy consumption is declining, indicating effective energy efficiency measures.
