 to all of you. 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, sort of 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 trustworthiness. And here the term trust already links probably to the technology that connects us here. Actionable means really we cannot continue with average data. So typically today very often databases are used, LCA databases, life cycle assessment databases with average values. So we need data that really comes directly from the suppliers and not just the direct ones, but the multiple tiers in the supply chain. And trustworthiness is sort of what you need at the very end that you see a label maybe on a product or a component and you really want to trust this value. And here I think it would be naive to think, oh, let's put protocol and footprints into a decentralized ledger, a distributed ledger, cook it up with a little bit of zero knowledge crypto and bomb, we have the trusted PCF value at the end. So this would not work, first of all, because you would not get all the suppliers potentially on such a system. You might not even get a single one because they are very reluctant to give out their sort of sacred data, the bill of materials, the bill of processes. And secondly, you need a source of trust really, you need the trust has to come from somewhere. And here we really think that we need more technology around verifiable credentials, which are more like a peer to peer exchange. We need the serenity and data provisioning. And that's where we really push quite a bit and maybe a bit later there will be more chance to talk about this. Dig into that. Doug? Thank you. So a happy overlap in a way. My name is Dr. Johnson Pernskine. I'm founder and chief executive of Circular. We're a five year old business and we use hyper ledger fabric as part of our platform. And what we do is traceability in complex industrial supply chains, a theme that was just talked about by Alex. We are helping, for example, we're helping car manufacturers, for example, who are building EVs to understand the inherited emissions from the supply chain. Most of us as consumers don't necessarily realize that although electric vehicles are supposed to be better for the planet, the vast majority of the emissions from the life of an electric vehicle come from its first manufacturer. Turning rock into battery grade materials in order to put a battery into an EV is massively energy intensive. And so understanding the contribution of the upstream participants to that carbon footprint is a real challenge. It's a challenge of trust, it's a challenge of data and extracting that data. And the same information can also be used to capture other ESG metrics whether it's water use or human rights abuses. Some of the raw materials in our electric vehicles, for example, come with concerns of child labor like Cobalt. We've been at this for five years. We now work with a whole host of car manufacturers around the world just being picked by the German government as the technology lead for projects to create a battery passport for Germany to meet the requirements of EU's battery regulations and branching out into other industries as well, other industrial materials that come with similar concerns around sustainability. So very much looking forward to this debate. Alex? Yeah, so thank you for having me very much on the panel. I'm Alex Altman, the Chief Operating Officer of SEAL Storage Technology. We're a decentralized storage provider built on top of the Filecoin ecosystem. We have a particular focus of commercializing the network and we're targeting a lot of the different Web2 institutions and bringing them over to Web3. We've had a lot of success talking to research institutions, academic institutions, as well as scientific institutions and creating different software platforms for them to be able to properly import their data into the blockchain and actually feel some of those benefits that the blockchain has to offer. You think immutability, chain of custody of data, as well as diversifying risk with eliminating a single point of failure risk. From an environmental impact perspective, we had to analyze what our biggest footprint was going to be and it became obvious that it comes from the electricity that we use in a data center. So we've got renewable energy data centers, but we've also taken it one step further and actually extracting the electricity usage directly from the output outlets within the data center so that we get a real-time measurement of the actual electrical output on top of our systems. We take that data and we measure it against the emissions from the various geographic locations of the data centers so we could try to put together the most accurate picture of what our emissions really are. But most importantly, it creates this open source and trustless system that people can come in and audit our data and to a certain extent actually creates an open source auditable process that we can iterate on what other people are looking at. Our hopes is to take what we're developing here and make it an easy changeover for other people in our industry and create a standard.
