10 Policy Changes for a Better Climate

A multi-agency government report released last week provides a stark reminder about the impact climate change will have on the global economy. That report signaled that unless immediate steps are taken, the impacts of climate change could reduce GDP by as much as 10%, or twice that of the 2008 recession. The report outlines not only the far-reaching impacts on our economy, but also how climate change will impact our health, transportation system, and military capabilities.

This report follows the publication last month of the Intergovernmental Panel on Climate Change (IPCC) Special Report, with its stark description of a rapid acceleration in global warming and the urgent need for emissions to reach net zero.

Transportation remains the single largest greenhouse gas (GHG) polluter, responsible for 28.5% of all emissions in the United States (EPA, 2016). Making our transportation system more efficient will not only aid the climate, but it will also improve the transportation system, reduce congestion, and enhance our quality of life.

While steps are being taken to make transportation cleaner, there are actions policy makers need to take to begin reducing GHG emissions immediately.  

Here are 10 policies lawmakers should implement

Reduce GHG emissions by increasing average vehicle occupancy - Incentivizing carpooling and vanpooling will increase average vehicle occupancy. Fewer cars on the roads means less GHG being emitted, it also means less congestion which benefits everyone. Policy makers should expand regional vanpool programs and create incentive programs that reward commuters who carpool

1. Municipal governments with tolled or priced facilities should provide preferential pricing for verified carpools.

2. Cities that do not have tolled or priced facilities should consider implementing a rewards program that financially (or otherwise) rewards individuals who carpool or vanpool to work.

Make sure autonomous doesn't mean empty

3. Initiate a verification system which requires autonomous vehicle operators to periodically report on average vehicle occupancy. As policy makers look to move away from a gas tax and towards a vehicle miles travelled tax, the policy should incentivize higher occupancy and deter vehicles with zero or one passenger.

Integrate and enhance transit operations with shared services such as bikeshare, carshare, and other shared mobility options.

4. Creating integrated and multimodal networks will provide people with options other than driving alone. Numerous studies have shown that access to carshare, bikeshare, and other mobility-on-demand services, coupled with transit, leads to reduced driving.

Price transportation – reward high occupancy vehicles

5. Pricing is a critical tool that can impact transportation usage. Integrating pricing strategies that reward high occupancy vehicles will encourage shared rides and reduce the burden placed on the transit system.

Work with Employers

6. How and when people commute to work can be influenced by employers. Employers should be provided with the tools and resources to encourage non-solo commutes. A number of policies and resources should be provided to employers including

a. Telework resources and training

b. Transit benefit ordinances and tools

c. Incentives to encourage non-solo commutes

d. On-site information for employees to choose the best way to travel


7. Continue to build out electric infrastructure and incentivize developers, employers, and even gas stations to include recharging facilities for electric vehicles.

8. Continue to expand tax incentives for the purchase of electric vehicles including in fleet operations.

Land-Use and Parking

9. Reduce parking limits and instead reward developers for integrating multi-modal transportation options such as carshare, bikeshare, transit, and other services that get drivers out of a car.

Work with the private sector

10. Work collaboratively with companies that can provide solutions to congestion and improved transportation. Create procurements that look to solve problems, not purchase products.

These 10 policies and solutions are common sense steps that any municipal governments can take to make an impact.
