Environmental issues span larger geographic areas but are sometimes left to the local level to address. Because of this, it is important to make sure that we prioritize protections for people across borders. At the local level, we can educate the communities about ozone pollution and what contributes to it. Since transportation is largely responsible, we can talk about lowering pollution from vehicles. This could be through encouraging the use of public transportation, encouraging the use of green transportation like biking or walking, or carpooling with friends. Doing these things would help decrease the pollution from transportation at the local level.

It is also important to make sure that at the national level we are being mindful of these things as well. For example, we could try and expand the use of electric or hybrid trucks for long-range transport. Public transportation services could also transition to hybrid or electric. We could also enact a law restricting the use of diesel in transportation. To help incentivize the switch, there could be a subsidy for companies that switch to hybrid or electric vehicles over diesel. If possible, we could have filters on long-range transport to prevent/lower their emissions.

There are ways that local laws can impact long range transport, and thus impact ozone levels. One example is that a port is required to refuse any vessels that are not in compliance with certain environmental regulations. This is a way to force the behaviors of foreign transporters- they cannot ship goods into a certain port without compliance. Another example would be airports prioritizing flights with lower gas emissions, thus forcing airlines to rethink their environmental policies if they still want to offer similar flight routes.

Of course these types of laws could have downstream consequences. Importers could take their business to other ports, and airline companies could cancel air routes all together. There would need to be programs in place to support these industries (airports or shipping ports) to overcome these losses and continue their programs. Eventually, the net losses would equilibrate as more and more airports or ports take on the same policies, and companies have no where else to turn.
