 So, I am with Siemens, it's a 175-year-old tech company, I'm in charge of cybersecurity and trust there, and to the topic of today, Siemens operates in verticals that really addresses roughly 63% of the greenhouse gas emissions that account for 63%, so it's a large amount, so it's buildings, it's transportation, it's industrial production, and so it's for us really an imperative to look into ways of decarbonization, and that's, as you probably know, if you're a little bit familiar with the topic, typically in four different areas, you can look at your direct emissions, indirect emissions, energy consumption for instance, you can look into the supply chain as it comes from upstream, that's actually the biggest challenge that links to the technology of blockchain and decentralization, and then the upstream part as well in the supply chain, and finally also carbon capturing and the possibilities to offset four emissions, and here we really see the big problem around actionable data on a product level as well as trust worthiness, and here the term trust already links probably to the technology that connects us here.
