 Yeah, good morning together. I want to talk about ESG with a bit of help so the original quote would of course be with a Help from my friend Indy, but I took it for so for the geeks with a bit of help and It's our ESG is a dry term so it relates to So the hyperledger community in a way So we what I would like to come forward with is what technology hyperledger technology can really do to help with ESG ESG stands for environmental social and governance and it really helps to give a view on sustainability for three different areas the the world area the environment and the people area the social aspects and then Of course the third one the the governance the the organizational area and as dry as it sounds There is quite an interest from The investor side in ESG and it has been proven that companies that follow up seriously on ESG really perform better financially and that is because of The long-term sustainability that is then also with the financial revenue that comes through the follow-up on the ESG Targets there are different schemes different frameworks where ESG is measured, but nevertheless, it's fairly difficult to really Have a have a grip on on the metrics on ESG metrics another reason why Companies perform better is also because of us so more and more we we go into a supermarket. We look at a product And we think oh is it so too? Neutral it has a particular carbon footprint maybe or we in certain products food products We we care about where the fish comes from where the ingredients come from maybe which region in the world How much how far I traveled so there there's more and more? Awareness from all of us and that puts pressure on the first Sort of supplier of a good, but then it triggers really down the entire supply chain and that's More a product level aspect of ESG and that's where I want to go With this sort of brief keynote here So on the product level We talk about something like the product Carbon footprint, so it's a term that really tells what is the the sum of emissions when you look from the cradle Where where basically everything came from the the mining and the material that goes into an end product But also the different steps the processing steps the manufacturing steps until a point where it actually leaves the gate So cradle to gate that's the product carbon footprint And you could look at other things like water consumption or the the product water footprint as it is called Or there are other aspects In terms on in terms of conflict minerals how many of these are within a particular product Of course it then relates where exactly were these minerals coming from it's not necessarily Just the fact that they are conflict minerals in there But it's the potential that there is an issue and other things like like Forced labor or the certification of the suppliers That that contribute to an end product and now There is a big problem because actually 90 percent of the information related to esg related Things come from the supply chain So as a single manufacturer as an organization you could look into your own factory environment production facility And you find out what is called scope one scope two So the local emissions in the co2 context it's called like this the local emissions the The energy consumption But it's very difficult in the supply chain To ask your supplier because your supplier again as a supplier and in the automotive industry What's up to seven steps that you have to follow up in order to Aggregate the final product carbon footprint So there is a problem and it is an ecosystem problem. It is a problem about trust decentralized Environment because suppliers sit anywhere in the world So we all sort of think naively well blockchain is the solution here and it can help to Track the aspects of a product along the supply chain and make everything more transparent and my Sort of apply would be really Is it really like this? Can we really just use a decentralized ledger? Everything from the from the different suppliers will be stored there and we can then do this aggregation and What we found out sort of I work for Siemens. We do a lot in industrial production suppliers will not be ready to give Critical information to such a system Even though it's blockchain and Yeah, we come with our value proposition of it's secure and safe and so on But it's the access really who can see the data that's that's not clear Even though this data might might be in a blockchain so There is the confidential data for instance the the bill of material the the number of Suppliers the mix of suppliers also the the ratio how you how you mix basically the sourcing so a lot of Sort of market critical or differentiation critical information that supplies would not want to hand over So what we came up with Is a slightly different approach where we use verifiable credentials pretty known To all of you I I think and we chain this approach of this this triangle of Having a certifier holder and a verifier along the supply chain So this triangle basically is it multiple times used in the supply chain And this approach came out of an association. So it's not a single company that drives this It's an it's an association that you call the asthenium association where this is promoted And we use Of course the indie stack In a running network. That's the id union network. Maybe some of you have heard of it It's a european indie network that is in production now run by a european Cooperative so a very interesting Legal entity also that is behind There where all the the members Have a very efficient way of operating this this network as well and Maybe lastly I just point to this graph where you see basically a request from a customer is then triggered through the supply chain And every supply has a certifier the certifier issues a credential it can be presented then by a supplier to the next tier And through this you don't know anything In the underlying decentralized infrastructure about The the actual values of the credentials because they exchange peer to peer Underlying are only the public keys of the Of the certifiers and they would be very happy that the world knows about their public keys And the the schemas that are that are being used for the data So that's in quick. I think this is already on zero. So I probably have to talk stop talking. So thanks a lot
