Introduction: California's commitment to combatting climate change traces back to the landmark California Global Warming Solutions Act of 2006 (Assembly Bill 32), which set ambitious goals for reducing greenhouse gas (GHG) emissions. The legislation mandated the development of a Scoping Plan by the California Air Resources Board (CARB), outlining strategies to achieve emissions reductions to 1990 levels by 2020. Subsequent updates have further refined these goals, with the 2022 Scoping Plan charting a course for carbon neutrality by 2045.
The 2022 Scoping Plan represents a paradigm shift, embracing a comprehensive approach to decarbonization across all sectors of the economy. This ambitious plan is underpinned by science, economics, and equity considerations. It extends and expands upon previous targets, setting the aim to reduce anthropogenic emissions to 85% below 1990 levels by 2045.
Key elements of the plan include:
- Aggressive Reduction of Fossil Fuels: Transitioning to zero-emission transportation, electrifying buildings, and phasing out the use of fossil gas are central strategies to reduce emissions.
- Investment in Clean Energy Infrastructure: Scaling up renewable energy sources and expanding clean technology deployment are essential for achieving carbon neutrality.
- Natural and Working Lands: Enhancing carbon sequestration in forests and other ecosystems, while addressing wildfire risks, is critical for offsetting residual emissions.
- Equity and Affordability: Prioritizing communities disproportionately impacted by pollution ensures an equitable transition to a carbon-neutral economy.
- Collaboration and Partnership: Collaborating with federal and international partners fosters innovation and accelerates global climate action.
The plan emphasizes cost-effective solutions that leverage existing technologies, while also recognizing the need for continued innovation and adaptation. It underscores the urgency of addressing climate change, as highlighted by the recent Intergovernmental Panel on Climate Change (IPCC) reports.
Moving forward, CARB's adoption of the Scoping Plan signals the beginning of a new phase of climate action. It will require concerted efforts to develop and strengthen regulations, remove implementation barriers, and engage stakeholders at all levels. The plan's success hinges on collective action and unwavering commitment to building a sustainable future for all Californians.
