Host: Once the manufacturers were identified, the experts carried out an audit of the most impactful points to reduce even more of the carbon footprint of our tower. Antoine: Everything. And so, for instance, when we were looking at the environmental impact of a ton of steel, we saw that the transportation was quite important. So that's why we are changing the type... Xavier: LCA stands for Life Cycle Assessment. It is a methodology to measure the environment impact across the whole life cycle of a product, and it's a multi-criteria method, meaning that you can measure CO2, but also other criteria like water, resource depletion. Antoine: So, when we look, then, at the life cycle assessment of the material itself, we can pinpoint the various impacts; so, manufacturing process, raw material sourcing, logistics, mining, etc. When looking at the Eiffel Tower, we are looking at a building that has been kind of circular from its inception. During the 130 years of its existence, we have changed parts. In this new tower, our idea is to continue this idea of circularity. So, we have designed a tower that can be productized, that can be dismantled, that can be also recycled. And this is really to give hope that sustainability and circularity are possible. Host: By optimizing the sourcing and the use of steel at each production step, the experts managed to considerably limit its CO2 emissions. Good news for our new tower, but we were not done yet with steel. A final polluting stage still needed to be optimized: its transport from the steel plant to the site.
