Novacem - Carbon Negative Cement Reduces CO2 Emissions

Cement manufacturing is an energy intensive process and typically generates LOTS of CO2.  It is estimated that cement manufacture produces 5% of global CO2 !
Novacem Carbon Negative Cement

The challenge for the developing world (and the developed world) is how to make cement and not make so much CO2.

 "... carbon negative cement ... based on a non-carbonate raw material, magnesium silicate, and uses a relatively low temperature production process. ... more CO2 is absorbed during production than ... emitted"'

Substituting a ton of Novacem in place of standard cement would avoid 852 kg of CO2 emissions.
Novacem is based in the UK.

Streetline Networks Technology Can Reduce Carbon Emissions in Cities

Streetline uses software and sensors to adjust parking meter pricing to reduce cars circling for parking spaces.  It is estimated that up to 30 % of carbon emissions are caused once a car is in the city - circling for a cheap parking space at a parking meter.  When meter prices are close to the rate of a parking lot the incentive to keep driving looking for a cheap meter spot goes way down ... as does wasted fuel and emissions and CO2.

" ... estimated that 30% of urban traffic congestion is caused by drivers looking for parking. ... reducing congestion ... makes finding a parking space that much easier. ..."
