The California Air Resources Board (CARB) staff announces the release of the beta version of the Mobile Emissions Toolkit for Analysis (META). This tool provides detailed assumptions for and visualization of the 2020 draft Mobile Source Strategy scenarios for medium- and heavy-duty on-road and off-road sectors.
Background
CARB is developing the 2020 Mobile Source Strategy, taking an integrated planning approach to identify the level of transition to cleaner mobile source technologies needed to achieve California’s air quality and climate targets. CARB held a webinar on March 25, 2020 and an informational board item on April 23, 2020 on the updated Mobile Source Strategy. California Senate Bill 44 requires CARB to update the 2016 Mobile Source Strategy by January 1, 2021, and every five years thereafter, to bring the State into compliance with federal ambient air quality standards and reduce motor vehicle greenhouse gas emissions.
To improve transparency behind the scenario modeling, CARB staff developed META for the on-road medium and heavy-duty and off-road sectors using the most current emissions inventory data. META is a user-friendly spreadsheet tool that provides a visualization of scenario results, in terms of technology mixes, fuel use and emissions. The tool also provides the major assumptions, inputs, data sources, inventory status for on-road and off-road sectors, as well as calculations for the heavy-duty on-road scenarios. Scenarios generated through META are used to understand how different combinations of concepts outlined in the 2020 Mobile Source Strategy will transform the fleet and impact the criteria and greenhouse gas emissions from the transportation sector.
CARB staff is releasing the beta version of META for external stakeholder testing and would like to receive feedback on the tool and it’s functionalities by September 4, 2020. The final version of META will be released along with the 2020 Mobile Source Strategy document.
