CEMEX announced that it has successfully introduced "ground-breaking" hydrogen technology as part of its fuel mix in all of its cement plants in Europe. The company is also moving quickly to extend this technology to the rest of its operations around the world, including Mexico, the USA, South, Central America and the Caribbean, Africa, and Asia.

The company executed initial trials of this technology at the Alicante Cement Plant in Spain in July 2019 and quickly confirmed its potential as a lever to significantly reduce CO₂ emissions. The technology was installed in 2020 in all cement plants in Europe. In 2021, CEMEX will roll this out to substantially all its global operations. With this new technology, hydrogen enhances the cement kiln's combustion process, adding another relevant tool in the company's 2030 roadmap to reduce CO₂ emissions in the short term.

In 2020, CEMEX announced its Climate Action strategy, defining a global target of a 35% reduction of CO₂ emissions per ton of cementitious products by 2030. For its operations in Europe, CEMEX also defined a 55% reduction target, in line with what the European Commission set as a new goal for all its member states. To complement this strategy with a longer-term vision, CEMEX also established an ambition to deliver net-zero CO₂ concrete to all its customers globally by 2050.
