AVOIDING CLEAN CONGESTION:
Green tech isn’t enough — we need to drive less.
By Steve Winkelman │March 27, 2019
“Clean congestion” is what we’ll get if we rely only on vehicle technology to meet climate change goals. Even with a massive shift to clean vehicle technologies, we will still need to reduce driving to meet greenhouse gas (GHG) emission reduction goals. Climate protection requires a paradigm shift to Travel-Efficient Development.

The Avoiding Clean Congestion video presentation answers the following questions:
How have transportation GHGs increased since 1990, and why?
Where are we headed?
How would a major shift to clean vehicle technologies impact GHGs in 2040?
What impact would Automated Vehicles have?
How can we meet climate change goals and avoid clean congestion?
What reductions in driving (VMT) are necessary?
What policies can help?
Technology is essential − but not sufficient − to achieving needed greenhouse gas reductions. We need good land use planning and urban design to create walkable, transit-oriented communities. And those communities will be more accessible, equitable, prosperous and resilient.
The Avoiding Clean Congestion video presentation video provides the following conclusions and recommendations:
Reducing driving by just 4 miles per day per household would enable us to meet our GHG goals and avoid clean congestion (6% < 2017 levels, 23% < 2040 levels)
Electric vehicles improve air quality, making walking and cycling more pleasant, more practical and healthier.
Travel-efficient communities increase accessibility, quality of life, resilience, prosperity and equity
We can avoid clean congestion through a variety of federal, state and local policies:
Ask the Climate Question: Does public infrastructure spending advance low-carbon, resilient communities?
Set GHG reduction targets for states and MPOs
Prioritize and invest in low-carbon transportation modes
Measure the right things: GHG and VMT per capita, access
Integrate land use, transportation, housing and climate policies
Provide Incentives and targets to reduce VMT/capita
Price parking, congestion/VMT and un-pooled rides
