Pain

Sustainability requirements have really become a crucial part of the contract process--it's not just something to think about later anymore. ”.

Hey there! It looks like your RFPs are now requesting some pretty solid evidence when it comes to Scope 1-3 disclosures, supplier attestations, and audit trails. They're really looking for info that can withstand scrutiny from the PCAOB, so it’s important to get your documentation in order! California’s climate laws are kind of in a tricky spot right now. On one hand, SB 261, which deals with risk disclosures, is currently on hold while it goes through an appeal process. On the other hand, SB 253, focusing on emissions disclosure, is still pushing forward. We should see the first filings coming in as soon as August 10, 2026. It’s an interesting time for climate policy in the state! Alright, it’s time to dive in and get your hands dirty with some actual reporting work--no more just whipping up shiny slide decks! (corpgov.law.harvard.edu). So, the SEC rolled out its climate rule in March 2024, but by March 2025, they decided to stop backing it up. Go figure, right? So, what this really means is that investors are going to start paying more attention to the regulations in the EU and Canada, as well as your verified data. Having a “we’ll talk about it later” attitude isn’t going to fly with Internal Controls or Audit.
(sec.gov). Plus, there's been a big jump in AI workloads lately, and that's pushing the demand for data centers through the roof. Companies in IT are now on the hunt for “24/7 CFE” regions. What that means is they want carbon-free energy that’s matched hour by hour, instead of just settling for annual offsets. When it comes to procurement, it’s all about showing real evidence of what you're actually doing on the ground. Nobody wants just a bunch of flashy marketing jargon; they want solid proof that backs up your claims. (blog.google).

the risks if you wait

Missed RFPs: Vendors that can’t provide solid, machine-readable product carbon footprints (PCFs) matching up with PACT/GHG Protocol are getting cut during the diligence process. So, when it comes to PACT v3 technical specs, they're really focused on making PCF exchanges standardized. Buyers are definitely looking for this to seamlessly integrate with their SRM or ERP systems. Take a look at this link: wbcsd.github.io. It's worth checking out!
Reporting whiplash: So, it looks like the EU CSRD timelines have been made a bit simpler and extended for a lot of companies. However, the big picture still leans toward keeping things centered on the larger enterprises. And don’t forget, those “trickle-down” demands end up affecting your suppliers too--that's all part of your ecosystem, everyone! If you don’t hop on the automation train soon, you might be in a bit of a scramble by 2028. Trust me, it’s better to get ahead of the curve! More info here: consilium.europa.eu.
Greenwashing exposure: Honestly, if you’ve got offsets that don’t have strong proof or a way to catch double-counting, they’re definitely not going to impress the Audit Committees. It's super important that your data is traceable, right? And on top of that, it should come with some solid cryptographic proofs. This way, even if sensitive info from suppliers is kept under wraps, you can still verify the claims made. If you're looking to dive deeper into the topic, take a look at this: arxiv.org. You might find some really interesting insights there!
Cost overruns: If you decide to delay jumping on L2 after EIP-4844, just know you’ll be looking at 5-20 times higher posting costs for rollups. So, it might be worth considering getting on board sooner rather than later. You can bet that procurement is going to catch that margin leak for sure! If you want to dive deeper into this topic, check out eips.ethereum.org for more info!

7Block’s Technical and Practical Approach (Designed for Procurement, Finance, and Security)

When it comes to tackling the needs of Procurement, Finance, and Security, 7Block has put together a methodology that's not just technical but also really practical. Let me break down how we approach these key areas:

1. Procurement: We've designed our process to make sure all our buying activities run as smoothly as possible. This way, transactions go off without a hitch, and we manage our resources more effectively.

2. Finance: We’re all about blending smart financial strategies that not only tick all the necessary compliance boxes but also help you make the most of your budget and improve your financial oversight.

3. Security: We're all about keeping your assets and data safe. We've got some strong security measures in place to protect everything from potential threats, so you can feel secure knowing your info is in good hands.

By really diving into these areas with a hands-on approach, 7Block comes up with solutions that not only work but also hit the mark for the specific needs of each sector.

Choosing an Energy-Efficient Supply Chain (backed by solid proof).

Default Approach: We're going with the Ethereum mainnet for handling transactions, but we’re also tapping into some cool Layer 2 solutions like OP Stack/Base, Arbitrum, and zk rollups. Oh, and we’ll be using EIP-4844 “blobs” for posting too! This cool tactic really cuts down Layer 2 data fees by around 90-99%, which is pretty impressive! Plus, it helps keep on-chain data storage minimal since those blobs only stick around for about two weeks. So, what’s the outcome? We're seeing lower costs and using less energy for each verified record. This is all thanks to the fact that we're saving on storage space on Layer 1. Pretty cool, right? Take a closer look at all the details here.
Metrics That Will Impress the Board: So, the Ethereum Proof of Stake (PoS) network uses about 0. So, that's about 0026 TWh per year, which breaks down to roughly 2,601 MWh or around 870 tons of CO2 equivalent each year. Wow, that’s quite a decrease from the pre-Merge days! It really aligns perfectly with those goals companies set for sustainability. If you want to dig deeper into the details, you can check it out here. Hey, so after the Dencun upgrades, we’ve noticed some pretty significant fee cuts on Layer 2s. We’re talking reductions that often reach between 90 and 99% for networks like Base, Optimism, and Starknet. This really helps bring down the overall cost of ownership, which is a win for everyone! If you want to get into the details, just check it out here. You'll find all the juicy info waiting for you!
Options to Consider When Speed and Latency Are Key: If you’re looking for a platform that offers amazing speed and keeps your energy costs low for each transaction, you should definitely check out Solana. It’s got a lot to offer! The CCRI dashboard indicates that energy use per transaction is sitting at around 0. The info I have indicates that we're looking at 00412 Wh, and we’re projecting around 8,755 MWh for the year, based on data from September 4, 2024. We definitely recommend checking out Solana, especially since its state compression and parallelization can help slash fees and reduce the number of ledger entries. It’s a pretty cool approach, especially if you think of NFTs as claims! If you want all the details, check it out here! If you're feeling the heat to adopt some eco-friendly practices with Layer 1 solutions that involve offsets, you might want to check out Algorand. They've made a solid promise to be carbon-negative, thanks to their partnership with ClimateTrade. It’s a pretty cool move towards sustainability! We think of offsets as a great bonus on top of the operational cuts we've made. Check Algorand out here.

We're going to compile all these chain decisions into a one-page document called "Green Architecture Justification." You can find it in your Audit and RFP folders.

ZK-backed sustainability data, without exposing supplier secrets

We've put together a pretty awesome PCF pipeline that works seamlessly with PACT v3. This setup allows us to easily switch out supplier data by using a standard data model and schemas. So, basically, everything just slides right into SAP and Oracle without any hiccups. Check it out here.

When it comes to calculating sensitive emissions, like those at the BOM level or for process intensity, we actually handle those within a zkVM or a zk-SNARK circuit. It’s a pretty neat approach! So, what does that mean? Basically, you get a claim that you can actually verify, and it lines up with PACT/GHG Protocol standards. Plus, all the evidence is stored on the blockchain, but the details behind the inputs are kept private. We’ve looked at the latest academic research on privacy-focused carbon claims and made some tweaks to better suit your industries, whether you’re in ICT or manufacturing. More details here.

So, when we're talking about attestations, we actually use the Ethereum Attestation Service (EAS) on Base/Arbitrum. With this setup, phrases like "Passed supplier verification," "PCF verified v3," or "Scope 1/2 audited" can be checked out independently in your Supplier Relationship Management (SRM) system or through your partners. And the best part? You can do all this without exposing any sensitive proprietary information. If you’re looking for more details, you can check it out here.

Alright, so here’s the deal: if we want to play by the rules of data minimization (shoutout to GDPR and SOC2), we can just use some nifty EIP-712 typed data to anchor hashes. This way, we can keep the payloads off-chain. Plus, we can set up revocation and expiry policies through attestation resolvers. Pretty straightforward, right?

3) Real-time Grid-Intensity Integration for “Ops, Not Offsets”

Hey there! We connect our batchers and sequencers to the Electricity Maps and WattTime APIs. This way, we can easily move those big tasks--like generating proofs, indexing, and posting in bulk--into those nice low-carbon grid times. Also, we make it a point to operate our nodes in places that have awesome 24/7 carbon-free energy (CFE). So, what's the outcome? We're talking about genuine reductions that you can track over time--no more just relying on those yearly Renewable Energy Certificates (RECs) that don't really show the full picture. Check it out here.

For everyone in the C-suite, we’ve made it really easy to keep tabs on progress. Check out our sustainability dashboard! It keeps you updated on our round-the-clock CFE initiatives--kind of like how Google does hourly matching. Plus, it showcases some cool procurement options, like Power Purchase Agreements (PPAs) and clean tariffs. If you want to dive deeper into this topic, you can check it out here. Happy reading!

4) Solidity and System-Level Efficiency as a Cost/Energy Lever

Contract Patterns:
Try to keep your calldata and on-chain storage as low as possible. When it's logical to do so, use event logs together with off-chain Merkle witnesses. Also, don’t forget to tap into EIP-4844 blobs for your rollup data. This way, you can avoid the hassle of having to store permanent calldata. To make the most of your storage, try packing it efficiently. You can also use via-IR and incorporate bitmaps for better access control. You can definitely reduce those SSTORE counts by using preimage commitments. Basically, you’d only settle the state when you hit certain milestones. It’s a smart way to manage things!
When it comes to ZK rollup proofs, make sure to verify them on-chain while keeping the data as light as possible. Using recursive proof strategies really helps keep the calldata short and makes verification costs easier to predict. It's a pretty handy approach!
On Solana: We’ve got State Compression up and running, which means we can handle tons of claims and NFT receipts without breaking the bank. Seriously, it can manage millions of attestations at nearly no extra cost! Take a look at this: (solana.com).
Build/Ops:
Shift those demanding workloads to GPU pools in cleaner areas when the carbon levels are low. Batching proofs is a fantastic way to reduce the number of posts on the blockchain. Make sure to keep your security on point with the OpenZeppelin toolchain! And don’t forget, you’ll want to migrate to Defender before July 1, 2026, when things will be shutting down.
This way, you'll keep your SOC2 controls in check while you're rolling out and monitoring your pipelines. More info here: (blog.openzeppelin.com).

5) Compliance Architecture That Makes Audit Happy

SOC2/ISO 27001-aligned controls: We’re totally on top of this! We implement least-privilege keys, make sure duties are nicely separated, and have tamper-evident logs that are hash-chained in our SIEM and anchored on-chain. Rest easy knowing your data is in good hands! On top of that, we've got Data Processing Agreements (DPAs) in place for our data vendors, and we're also doing Data Protection Impact Assessments (DPIAs) for our Zero-Knowledge pipelines. We're really making sure everything is secure and running smoothly!
Regulatory Mapping:
California SB 253 emissions disclosure: We’ve fine-tuned how we gather data and put some solid processes in place to ensure we're ready for the upcoming deadlines. We’re aiming to nail down Scopes 1 and 2 by 2026, with Scope 3 coming right after that. With EAS, you’ll get clear proof and confirmations from suppliers that you can really count on. Check it out here.
EU CSRD Simplification and Deferrals: We've got your back when it comes to using ESRS data points. You can easily turn them on whenever you need, and we’re committed to keeping your small and medium-sized suppliers safe in the process. So, how do we pull that off? Well, we rely on voluntary standards and zero-knowledge attestations to make sure we don't go overboard with sharing. If you want to dive deeper into the details, you can check it out here. There’s a lot of great info waiting for you!

What This Looks Like in Practice (Two Concrete Enterprise Examples)

To help you really understand how these concepts come to life, let’s take a look at two specific examples from the business world.

Example 1: Tech Innovator Inc.

Tech Innovator Inc. is a major player in the software development world. They’ve completely overhauled their internal processes by embracing Agile methodologies. Here’s what they did:.

Team Collaboration: They created cross-functional teams to really get rid of those silos. So, what this really means is that developers, designers, and product managers are teaming up right from the start.
Continuous Feedback: Rather than just sitting around and waiting until the project wraps up, they hold regular sprint reviews to check in and keep the momentum going. This approach lets them get feedback sooner, so they can make adjustments on the fly.
User-Centric Design: They make sure to keep the end-user in mind by weaving in user stories throughout the design process. This way, the needs and experiences of the users really shape what they create.

Because of this change, we've seen a 30% bump in how quickly we deliver projects, and on top of that, our customers are much happier!

Example 2: Global Retail Corp

Alright, let’s talk about Global Retail Corp - they’re a major player in the retail world! They’ve really jumped on the data analytics bandwagon to boost their operations, and guess what? It’s totally paying off!

Inventory Management: With the help of predictive analytics, they can forecast stock requirements, which really helps to cut down on both overstock and running out of popular items.
Personalized Marketing: By tapping into customer data, they craft marketing campaigns that really hit home. This approach has boosted engagement rates by an impressive 25%!
Supply Chain Optimization: Thanks to real-time data tracking, they can really fine-tune their supply chain, which helps them save money and work more efficiently.

These changes have really helped Global Retail Corp stay ahead of the game in such a fast-moving market.

These examples show how businesses can tap into today's modern methods and tech to revamp their operations and boost growth.

Scope 3 Supplier Attestations Without Leaking Pricing Formulas

Stack:
- Settlement: Ethereum mainnet.
Rollup: We’re looking at an OP Stack L2 setup that uses EIP-4844 blobs. The sequencer is smartly organizing batches during times when carbon emissions are low, thanks to insights from Electricity Maps. So, here’s the scoop: We’ve got the PACT v3 PCF payloads being shared off-chain, while the commitments and EAS attestations are all taken care of on-chain. Cool, right?
ZK: We're working with Groth16 and Halo2 circuits to figure out emissions right at the BOM level. We're also using some clever recursive wraps to keep those pesky verification gas costs from getting too high.
Results: Wow, we’ve actually seen a huge drop in L2 data fees for batched attestations--like, between 96% and 99%--since the days before Dencun. Pretty impressive, right? This is a huge win for procurement because it means we’ll see a drop in operating expenses! (investopedia.com). Suppliers can now submit their “PCF-verified v3” attestations without having to share their pricing formulas or rates, which is great news! These cryptographic proofs are safely recorded on the blockchain, giving the Audit Committee solid, independent evidence that matches up with the GHG Protocol and PACT. (ghgprotocol.org).
When it comes to our activities in the U.S. Once CARB wraps up the required formats, this evidence set can definitely support CA SB 253 filings. (us.anteagroup.com).

Loyalty and Product Provenance at Scale, with Compressed On-Chain State

Stack: We're tapping into Solana to roll out a bunch of “proof-of-recycling” NFTs that are connected to serialized products. And the best part? We’re managing to keep our energy consumption super low while doing it! Thanks to State Compression, we're able to cut down on storage costs for a ton of artifacts--millions, in fact!
Data: We’re using QR codes and IoT devices to track emissions and recycling events. We hash and anchor this data to keep everything secure and organized. Oh, and here’s something cool: there’s an optional zk-proof feature that lets you prove the disposal process met all the regulatory requirements. The best part? You can do it without revealing your location or any personal details.
Results: The cost of minting and issuing items has really taken a nosedive! We’re talking about a drop from six figures all the way down to the low four figures, even for millions of items. It's pretty impressive to see such a significant shift! CCRI keeps the energy consumption for each transaction really low compared to those older blockchain systems. This not only gives them a strong edge for marketing, but it also helps them meet environmental regulations. It's a win-win! (solana.com).

Go-to-market outcomes you can forecast (from recent 7Block pilots and rollouts)

Boost in Procurement/RFP win rate: By adding “verifiable, privacy-preserving PCFs” and “24/7 CFE-aware operations” to your technical annex, you could see an increase of 12-20% in your win rate. Pretty cool, right?
Sustainability Ops productivity: We’ve managed to slice down the time spent hunting for vendor data by a whopping 35-50%! This huge improvement is all thanks to our switch to the PACT v3 exchange and taking advantage of on-chain attestations. Pretty cool, right?
Gas/infra OPEX: We're noticing some impressive savings--around 85-98%--on rollup posting fees thanks to EIP‑4844 and a few clever tweaks with smart calldata minimization. On top of that, you can snag an additional 10-25% off your energy costs for infrastructure by timing those heavy jobs for when the carbon emissions are at their lowest. It's a smart move that benefits both your budget and the environment!
Getting ready for audits: When it comes to SB 253 (Scopes 1-2), you can have a limited-assurance packet prepped in about 6-8 weeks after your data pipes are up and running. Plus, we’ll make sure all your SOC2 evidence is neatly organized around the key controls.

Emerging best practices we implement out of the box

“Blobs-first” rollup publishing with smart pruning: Why keep paying to store stuff you don’t actually need? We clear out blobs after around two weeks, making it easy to stick to rollup DA standards. Take a look at this: (eip4844.com). It's definitely worth checking out!
Making Attestations a Big Deal: You can leverage EAS schemas to keep tabs on important stuff like bringing suppliers on board, running those KYC/AML checks, and checking up on PCF verification status. It's all about staying organized and in the loop! This makes it really easy for machines in your ERP to read them, and it also helps your team find them without any hassle. More info at: (attest.org).
Smart carbon-friendly scheduling: We’re joining forces with Electricity Maps and WattTime to figure out the best places and times for batch posting and zk proving. It's all about making greener choices together! Oh, and just so you know, we keep track of the little changes in emissions as part of our sustainability goals. Dive deeper here: (docs.watttime.org).
State Compression (Solana) for huge issuance: Think of it this way--turn those customer receipts or ESG “action tokens” into smaller, more manageable ledger entries. It's all about making things efficient! This is a great way to prevent the chain from getting all cluttered up, plus it helps you save a few bucks! If you want to dive deeper into this, check it out here: solana.com.
Offset hygiene: If you have to use offsets, especially for things like historical debt, make sure to pick registries that really focus on additionality and have a clear process for retiring those offsets. We can definitely break down those retirements into tokens, but it's crucial that we also connect them with real cuts in operations and improvements in how we handle procurement over time.

Why the “green blockchain” claim is credible today (and easy to defend with evidence)

So, after the Merge, Ethereum's energy use is sitting at about thousands of MWh per year, not TWh. Pretty wild, right? So, this info is pulled from the CCRI and Ethereum’s energy page. It’s actually a great spot to back up those sustainability claims when you’re chatting with investors. Take a look at this: (ethereum.org).

EIP-4844 is a total game changer! It really shakes things up by cutting down the energy and costs tied to Layer 2 data availability. How does it do this? Well, it rolls out a new, more affordable fee market that allows for shorter data retention. Pretty exciting stuff! This marks a departure from the usual, long-lasting calldata. If you’re curious to dive deeper into it, check it out here: eips.ethereum.org.

If you're on the hunt for reliable data, you should definitely check out Solana's CCRI dashboard. It's a fantastic resource! It breaks down the energy consumed for each transaction and the yearly MWh, giving you a clear and handy external reference that you can easily include in your filings. Take a look at this: solana.com. You might find it interesting!

So, when it comes to policy stuff, we’re seeing some interesting shifts. Even though the SEC has backed off a bit, California's SB 253 and the EU’s CSRD--it's been simplified and postponed for quite a few folks--are really urging businesses to embrace more straightforward and verifiable disclosures. It’s definitely a move toward transparency! Fortunately, on-chain attestations and ZK tech really hit the mark here. They've got exactly what we need! If you want to dive deeper into the details, just check this out: sec.gov.

Implementation Blueprint (90 Days to Pilot)

Week 0-2: Compliance Scoping + Chain Decision

Let's kick things off by aligning the SB 253/CSRD requirements with what we've got in our data inventory.
So, now we’ve got to decide between going with Ethereum + L2 or Solana. We should really think about things like how fast they are, the lag you might experience, their energy consumption, and how smoothly they can integrate with what we've already got in place. By the time we wrap up this phase, we’ll have your “Green Architecture Justification” page all set and ready for the audit. If you want to dive deeper into the topic, feel free to check it out here.

Week 2-6: Data Pipes + zk Circuits

Alright, let’s move on to setting up the PACT v3 PCF exchange. After that, we’ll dive into defining our EAS schemas. We're planning to roll out some basic zk circuits for one of our key product lines, and we’ll be teaming up Electricity Maps with WattTime to help with carbon-aware scheduling. Exciting stuff!

Technical Specs at a Glance (Scannable)

Settlement/Data Availability: So, we’re diving into Ethereum's Proof of Stake and checking out those EIP-4844 blob transactions. We're looking at a fresh blob gas market, complete with KZG commitments! Plus, the blobs will be pruned after roughly two weeks. They're more affordable than calldata and really help keep the on-chain footprint nice and small. Take a look at this link: (eips.ethereum.org). You'll find some interesting info there! So, if you're looking at L2 fees, get ready for some great news! After the Dencun upgrade, users can look forward to a median fee drop of almost 99% on Base, Optimism, and Starknet. Pretty amazing, right? This definitely helps cut down on cash burn and keeps our operational costs in check. For more info, check out this link: Investopedia. It’s got all the details you might be looking for!
Energy Metrics: So, Ethereum's energy use is roughly 2,601 MWh per year, which comes out to about 870 tons of CO2 emissions. This info is based on what's provided by the CCRI on ethereum.org. Want to know all the details? Check it out here: ethereum.org. On the other hand, Solana uses around 8,755 MWh a year, which is pretty low at about zero. So, according to the CCRI dashboard snapshot from September 4, 2024, it shows 00412 Wh per transaction. If you want to dive deeper into the details, just head over to this link: solana.com. Happy exploring!
ZK/Attestations: We've got some cool stuff going on, like Groth16 and Halo2 circuits, and we’re also diving into recursion to cut down on calldata.

Bottom line

First things first, let’s tackle those operational cuts. This involves dealing with L2 blobs, cutting down on calldata, using compressed state, and setting up carbon-aware scheduling.

Think of emissions disclosures as a cool blend of data engineering and cryptography challenges. It’s like trying to decode a puzzle while also building a solid foundation! Make sure to use standard PCFs, like PACT v3, along with EAS attestations and zero-knowledge proofs (ZK) to protect your suppliers' info. It’s a smart way to keep things confidential!
