From the Ted Talk by Karen Scrivener: A concrete idea to reduce carbon emissions

Unscramble the Blue Letters

So the possibility to replace Portland cement with a different material — but with the same proietpres, produced in the same processes and used in the same way, but with much lighter carbon footprint — is really crucial to confront cmaltie change because it can be done fast and it can be done on a very lagre scale with the possibility to eliminate more than 400 million tons of CO2 every year. So we can't do without concrete, but we can do without a significant amount of the emniisoss it produces.

Original Text

So the possibility to replace Portland cement with a different material — but with the same properties, produced in the same processes and used in the same way, but with much lighter carbon footprint — is really crucial to confront climate change because it can be done fast and it can be done on a very large scale with the possibility to eliminate more than 400 million tons of CO2 every year. So we can't do without concrete, but we can do without a significant amount of the emissions it produces.
