Is walking worse for the planet than driving? This startling claim has been published in high-profile media outlets, including the New York Times blogs. This case study examines the idea that the life-cycle greenhouse gas emissions of food needed to replace the calories burned by walking could exceed the life-cycle emissions of the fuel needed to drive a car the same distance. It finds that when realistic assumptions about a walker’s diet are taken into consideration (i.e. when it is assumed the diet is not exclusively based on beef products), walking makes more sense for the environment than driving.
There is broad recognition that adapting to climate change, coupled with the need to address aging infrastructure, population growth, and degraded ecosystems, will require rethinking programs and policies and investing in our natural and built water systems.
This is the latest in our What Happens Next series. The increasing scarcity of drinking water is beginning to capture the world's attention -- but surprisingly, an innovative solution might just be found in one of the Earth's driest places.
Stormwater has traditionally been managed to mitigate flooding and protect water quality. However, its potential as a local water supply has gained recent attention in water-stressed areas. As climate change increases the risk of both floods and droughts in California, urban stormwater capture also offers a significant opportunity to enhance community resilience.
