Keep Up the Measurement Pressure
Although SweetLightning talks about many promising ways to reduce greenhouse gases, emissions are still rising. One thing we can do about it: Keep measuring, and be specific.

EVs Deliver Lowest Lifecycle Carbon Footprint Everywhere
Cradle-to-grave GHG emissions of light duty electric vehicles are lower than all forms of their internal combustion-engined equivalents, no matter the region

Cement can retain and re-emit heat. That might be good in a greenhouse in winter, but isn't good when in structures that are already too hot. "Cooler #Cement" is important.

Cooler Cement
Changing the surface microstructure of cement reduces concrete's contribution to global warming by keeping structures cooler

EROI and The Net Energy Cliff
EROI is measures the fundamental idea that the less energy you need to invest to get energy in return, the more will be left over for society to do other things that keeps civilization going.
