The Kalifornia Malakoff project is the first commercial new-build project in France to use the low-CO2 Saint-Gobain Orae glass. The glass in this series reduces the CO2 emissions of the base glass by around 40 per cent. The residual footprint is offset by a CO2 compensation of 11 tonnes in the project, resulting in a zero carbon footprint for the CurvePerform curved glazing, according to the project managers.

In addition to Orae glass, Cool-Lite Xtreme 70/33 II glass was also installed in the façade elements for the "Kalifornia Malakoff". The flat glass is produced by Sivaq in France, while the curved glazing with Vandagreen CurvePerform OraeCool-Lite Xtreme 70/33 II was manufactured by the Berlin vandaglas branch - formerly Döring Glas.
What the glasses do with a minimised CO2 footprint
The curved CurvePerform glasses made from Orae LowCarbon Glass have an average CO2 footprint of 23.50 kg CO2e/m² for the base glass and 78.50 kg CO2e/m² for the end product (including Scope 1 & 2).

For comparison: without Orae, i.e. using the base glass SGG Planiclear, the CO2 footprint is 43.92 kg CO2e/m² for the base glass and 98.92 kg CO2e/m² for the end product.
