Combined, the cement industry (6%) and the aviation industry (2%) produce 8% of the world's total carbon dioxide emissions. With this project Ecocem, Heathrow and Cemex, aim to demonstrate the viability of low carbon products, and tangibly reduce carbon emissions from construction at airports. In order to reach its net zero aviation by targets by 2050, Heathrow is looking to cut at least 45% of on the ground carbon emissions by 2030. Working with Ecocem and Cemex on this project enables Heathrow to continue to lead the charge in advocacy and change on reducing carbon emissions in the aviation sector. Demonstrating that its products and technologies can be applied to large scale infrastructure projects isn't new to Ecocem. At present it is providing low carbon binder for use in concrete on the HS2 project in the UK and for the Metro extension project in Paris, connecting the city to its neighbouring areas.
