Our Commitment

For many years, we have demonstrated our commitment to healthy communities and a balanced, equitable and sustainable transportation network. Embracing a zero-emission bus future by building the world’s largest hydrogen fueling station. Pioneering microtransit to reduce congestion and vehicle miles traveled. Identifying climate-change stressors to ensure a strong region prepared for the journeys ahead.

In all, we consider the environment.


Preserving & Conserving Land & Water

Orange County voters told us to prioritize the environment. For decades, we’ve kept that promise.
