1.5°C Business Leadership

Solutions, strategies, and mindsets for our only future.


Dalmia is repurposing industrial waste products, turning industry byproducts and scrap into a cement high on strength and low on environmental impact.

By substituting a percentage of cement ingredients with industry waste products, Dalmia saves natural resources and helps to reduce the environmental impacts of its industrial processes. The blended cements include industrial waste products such as fly ash from coal-based thermal power plants and waste from the steel industry. These additives lead to reductions in limestone mining and improvements in energy efficiency with reduced CO2 emissions from the actual manufacture of their cement, resulting in an average intensity of 526kg/t compared to the global average of 900kg/t.

Dalmia is part of the Caring for Climate initiative and uses an internal carbon price to generate funds for investing in low-carbon technology. The company continues to innovate, driving up the percentage of waste products incorporated in their cements to simultaneously drive down their greenhouse gas emissions and sequester carbon from the atmosphere with the clear goal in mind to achieve net negative emissions by 2040. Dalmia was the first heavy industry sector company to make this commitment. The company is currently five times water positive and has pledged to become a 10 times water positive cement group by 2030.

Dalmia’s 1.5°C commitment

Dalmia was ranked as the most sustainable cement producer in the world by the Carbon Disclosure Project in 2018. The company was the first in the industry to become a member of RE100 and EP100 projects, and recently announced a commitment to set science-based targets aligned with a 1.5°C scenario.

How the Global Goals are addressed

Responsible Consumption and Production

Utilizing otherwise wasted resources helps to reduce demand for limestone and reduce carbon emissions in the construction sector.

Climate Action

Cement production can be an extremely carbon intensive process. Using waste products from other industrial activities can substantially lower the carbon footprint of cement production.
