Taking public transportation is one of the most environmentally friendly things you can do.

By taking cars off the road, Miami-Dade Transit cuts down on smog and greenhouse gas emissions that cause global warming. Those benefits will increase over the next few years as MDT transitions its fleet to cleaner-burning, more fuel-efficient hybrid buses.

In addition, MDT is testing the use of biodiesel in its buses, which further reduces greenhouse gas emissions that cause global warming by decreasing the use of fossil fuels.

Miami-Dade Transit also is helping the environment with its 900-plus bus shelters, which utilize solar-powered lighting, and an extremely bike-friendly system that allows patrons to bring their bikes with them when they ride.

And MDT participates annually in national celebrations of Dump the Pump Day, which promotes the environmental and other benefits of public transportation.
