Why MXDs??

 

New research: Mixed-use developments cut vehicle emissions by up to 80%
A longitudinal study across 36 US regions and 710 mixed-use developments reveals measurable climate benefits that improve over time:

 Key findings:
- MXDs generate 33% less VMT than conventional developments
- Up to 80% reduction in some regions
- 50% fewer vehicle trips over time as developments mature
- People walk more in MXDs with rich built-environment features
- 6x lower GHG emissions per trip in compact regions vs sprawling areas

 Planning implications:
- Job-housing balance directly reduces driving
- Intersection density + transit access = fewer car trips
- Walking trips alone explain 25% of VMT variation
- Regional context matters - compact regions see dramatic benefits
 
For urban planners: compact, mixed-use, transit-oriented development delivers measurable climate action that gets better with age.
 Time to update those zoning codes.
