Hello everyone, I'm Nollaig, I'm head of communications at Holcim. We are a global leader in building solutions with a portfolio ranging from construction materials all the way to building systems and i'm here today to answer some questions from TCS on how to accelerate our world's transition to net zero. So first question, do you see technology as the most effective weapon in the battle for a sustainable future ? Definitely, technology is a key catalyst and plays a vital role to accelerate net zero transition. If i presented you to a class of six year old's now, what would you tell them is the most important thing they can learn about sustainability today ? Everybody has a role to play, no action is to small. So take action for climate and go circular today. How does Holcim champion sustainability in your sector ? At Holcim, we are on a mission to decarbonize building and we're putting our expertise to work from green concrete to eco pact all the way to green roofs to make cities and buildings more sustainable. Do you believe that the progress made so far on sustainable construction is enough ? The shift to sustainable construction requires deep collaboration across all the players of the value chain and we're here to accelerate that collaboration. The more we collaborate, the faster we're going to get there. So what can we learn about the natural world, about sustainability ? Everything is connected into one giant ecosystem. What happens in our cities spills into our ocean, goes into our atmosphere, and so on and so forth so take a systemic view at everything you do to accelerate the shift to net zero. Thank you , TCS, for hosting us today. let's collaborate even further to accelerate the shift to green building.
