Better Concrete Here and Now

Greg Whitchurch

While it’s heartening to read here about some of the research and development efforts for lower-carbon concrete, in the meantime standard concrete is contributing to irreversible climate damage.

Climate crisis disasters are driving “climate migration.” A few years ago, Vermont created a commission to address the enormous stresses of soaring immigration to our […]
