Las investigaciones científicas más recientes de la Oficina de Evaluación de Riesgos para la Salud Ambiental (OEHHA, por sus siglas en inglés) indican que dos sustancias tóxicas —la acroleína y el óxido de etileno— pueden presentar riesgos de cáncer considerados inaceptables. En respuesta, el gobernador de California, Gavin Newsom, propone una inversión de 2.5 millones de dólares destinada a profundizar la investigación científica e identificar medidas para reducir la exposición a estas sustancias y proteger la salud pública. 

What you need to know: The latest science from the Office of Environmental Health Hazard Assessment (OEHHA) shows two toxics, acrolein and ethylene oxide, can potentially pose unacceptable cancer risks. In response, California Governor Gavin Newsom is proposing a $2.5 million effort to advance scientific understanding and identify actions to reduce exposure and protect public health.  
 

What you need to know: The California Clean Fuel Rewards program is now accepting applications from retailers to offer point‑of‑sale rebates for electric medium- and heavy‑duty trucks with funding from the state’s Low Carbon Fuel Standard. Rebates will be available statewide at the end of June to help fleets access and deploy zero-emission electric technology.  

What you need to know: California’s incentive program for medium- and heavy-duty trucks and buses has delivered more than $1 billion in funding to fleets statewide, supporting thousands of clean truck and bus purchases and reducing emissions while improving air quality in communities most affected by air pollution. The program continues to support clean transportation in California, and with demand at an all-time high, underscores the program’s impact statewide. 

What you need to know:  The California Air Resources Board (CARB) permanently adopted the Emergency Vehicle Emissions Regulations that were initially adopted in 2025 as a temporary measure after the federal government purportedly   disapproved California’s waivers for newer vehicle emissions regulations, including Advanced Clean Cars II (ACC II) and Heavy-Duty Engine and Vehicle Omnibus (Omnibus). The amendments clarify that California’s earlier emissions regulations will remain in-place.   
 

What you need to know:  The California Air Resources Board (CARB) approved an item at its February meeting to establish the administration and implementation fees for the Climate Corporate Data Accountability Act and the Climate-Related Financial Risk Act, and the first-year reporting deadline under the Climate Corporate Data Accountability Act.

SACRAMENTO – Today at noon (PST), California and Quebec released the results of the 46th joint California Cap-and-Invest and Quebec Cap-and-Trade auction of carbon allowances from both jurisdictions. The final numbers include sales figures and settlement prices for Current Vintage allowances (2024, 2025, and 2026) and Advanced Vintage allowances (2029).

Current Vintage

Number offered: 54,975,757 

Number sold: 54,975,757

Settlement price: $27.94

What you need to know: CARB released an updated inventory calculating carbon stored in California’s natural and working lands using design principles established by the Intergovernmental Panel on Climate Change (IPCC). The data show plants have absorbed twice the carbon lost to wildfires, demonstrating the important role of nature as the state works toward carbon neutrality.

What you need to know: California continues to lead the nation in replacing polluting diesel school buses with zero-emission models, thanks to nearly $1.4 billion in state investments, according to a new report. Unfortunately, federal funding for zero-emission school buses is in doubt. 

What you need to know: Applications are open for Community Planning and Capacity Building Grants. Up to $7.3 million is available, with individual grants up to $500,000. New this year: funding is more accessible to tribal governments.
