At CEMEX, we are seeking to invest in upgrading our cement plants, trying to maximize the use of alternative fuels to power our kilns and transition away from fossil fuels. In 2019, we pledged more than US$50 million to invest in an innovative global program to replace fossil fuels with alternative fuels. Among our initiatives, we are starting to integrate an innovative new hydrogen-based technology to enable our cement kilns to increase their use of alternative fuels by optimizing their combustion process, while lowering their consumption of fossil fuels and reducing their CO2 emissions.
