PT Semen Indonesia (SIG) has earned five Green Label Indonesia Platinum certificates across its factories. The company is focusing on reducing emissions by using alternative fuels, waste as raw materials, and digital efficiency tools in its production process. SIG reports that its green cement produces 38% less carbon than conventional ordinary Portland cement. This shift aims to provide the construction industry with lower-emission building materials to support sustainable development goals.

A 38% reduction in carbon is a decent start for cement, but the real test is the cost difference. If the green version costs significantly more, developers will stick to conventional OPC unless local building codes force the switch.
That is where procurement rules come in. If the Indonesian government mandates a minimum percentage of low-carbon materials for public infrastructure projects, the volume will drive the price down regardless of initial margins.
SIG is pushing low-emission materials and claiming a 38% carbon drop compared to standard cement. They are using alternative fuels and waste to get there. It is a standard industrial decarbonization play.
They mention using renewable energy in production. I wonder what the actual mix is. Are they installing on-site solar or just buying credits? The energy intensity of cement kilns is massive, so the source of that power matters.
