Sure, I can provide you with some facts about cement production and its impact on climate change. Please note that the figures mentioned here are approximate and might change over time.

Cement production accounts for approximately 8% of global CO2 emissions. This is because producing cement involves the calcination of limestone (calcium carbonate), which releases significant amounts of CO2.

In Germany, the cement industry contributes about 3-4% of the total national CO2 emissions. However, this number can vary depending on the year and the data source.

On average, the production of one ton of cement generates around 0.6 to 1 ton of CO2 emissions. This figure varies depending on the type of cement, the efficiency of the production process, and the use of alternative fuels and raw materials.

The cement industry has been working on reducing its carbon footprint through various means, such as increasing energy efficiency, using alternative fuels, developing innovative cement formulations, and employing carbon capture and storage (CCS) technologies.

Additionally, there is a growing interest in alternative building materials, such as geopolymers or bio-based composites, which could potentially have a lower carbon footprint than traditional Portland cement.

It is important to note that the figures provided here are for general informational purposes and may not be completely up-to-date or accurate for a specific region or time period. It is always best to refer to the latest data and sources for accurate information.
