California's Low Carbon Fuel Standard (LCFS) is a market-based policy designed to reduce greenhouse gas (GHG) emissions from the state's transportation sector. It is a key part of California's climate strategy and serves as a model for other regions aiming to decarbonize their fuel supply.

‍
The LCFS operates by setting a progressively declining carbon intensity (CI) target for transportation fuels each year. Carbon intensity measures the lifecycle GHG emissions of a fuel, from production to end use. Fuels with a CI below the annual benchmark generate LCFS credits, while those exceeding it incur deficits. One LCFS credit represents one metric ton of carbon dioxide equivalent (CO2e) emissions reduced or avoided.

‍
Fuel providers in California must ensure their overall fuel mix meets the LCFS carbon intensity standards. They can achieve compliance by producing low-carbon fuels or by purchasing credits from other parties with a surplus. This market-based approach promotes the adoption and production of cleaner fuels and technologies.

‍
The LCFS program offers three main pathways for credit generation:

• Fuel Pathway-Based Crediting: This common method awards credits to fuels with a carbon intensity lower than the annual benchmark. This includes fuels like electricity, renewable natural gas (RNG), renewable diesel, biodiesel, ethanol, and hydrogen, each undergoing a rigorous lifecycle analysis to determine its CI score.
• Project-Based Crediting: Credits can also be generated through projects that reduce GHG emissions within the petroleum supply chain or through carbon capture and storage (CCS) initiatives, including direct air capture technologies. These projects are credited based on verified lifecycle emission reductions.
• Capacity-Based Crediting: Introduced in 2018, this mechanism supports the deployment of zero-emission vehicle (ZEV) infrastructure, such as hydrogen fueling stations and electric vehicle fast-charging sites. Credits are based on the infrastructure's capacity, encouraging the development of clean transportation ecosystems.

‍
The LCFS has been effective in reducing petroleum dependency and GHG emissions in California's transportation sector. However, the market has faced challenges, particularly with price volatility. The LCFS credit price has fluctuated significantly, dropping from around $185/tonne to $75/tonne between 2019 and 2023, with a 33% fall in the past year. This downward pressure is largely due to a growing credit bank and surplus of credits, driven by the rapid increase in electric vehicle adoption. A single electric vehicle can generate about 10 LCFS credits, and with EV use projected to quadruple by 2030, this surplus is expected to worsen.

‍
To address these market imbalances and maintain effective decarbonization incentives, the California Air Resources Board (CARB), which administers the LCFS, is actively pursuing reforms. These reforms aim to balance credit supply and demand, with a goal of achieving more stable credit prices, potentially in the $100 to $200 per credit range.

‍
The LCFS also interacts with federal policies like the Renewable Fuel Standard (RFS), as biofuels used for LCFS compliance can also earn RFS credits (RINs). Furthermore, the LCFS model is inspiring similar clean fuel standard policies in other states such as Oregon and Washington, and a federal LCFS credit is being established under the Inflation Reduction Act starting in 2025.
