We all want an open, inclusive community to decide on climate-related questions such as: Is a carbon offset legitimate? Is a company realling taking positive climate action? Is a product really green? Yet in the age of social media, it’s hard to know whether people who write reviews have actually bought a product, or even […]
Background This tutorial explains how to build a complete Ethereum dApp using React.js, web3Modal, ethers, and Hardhat. The dApp we built here is an open source carbon emissions trading application in greenhouse gas (GHG) emissions that cause climate change. In this dApp, emissions auditors can issue tokens of emissions to individuals and organizations, who could […]
This is a video of the Emissions Tokens Network we’ve discussed on the Hyperledger wiki:
This video is from our recent presentation at the Linux OSS Summit Europe about fighting climate change with blockchain: This video shows you what it looks like now, with opentaps and our Hyperledger Fabric blockchain carbon accounting project:
I will be giving a talk for the Linux Foundation OSS Summit on “Fighting Climate Change with Blockchain and Open Source” on Monday October 26 at 12 PM GMT/8 AM EST/5 AM PST. This will be a virtual event that you can attend from anywhere in the world. Here’s the synopsis of my talk: If climate change […]
We’ve been busy getting ready for the next step of opentaps, and I wrote a high-level preview of it as a guest post entitled “How Blockchain Provides the Missing Links in Climate Action” for Meeting of the Minds. In a nutshell, we see the potential of the blockchain to tie together emissions data, including those […]
So you got the Clean Energy bug. You invested in energy efficiency projects at your buildings, added renewable energy, or maybe purchased Renewable Energy Certificates to make your building run on 100% clean energy. That’s great! We’re all grateful for what you’ve done for the planet and to stop climate change. But now what? How […]
Getting data from a utility could be difficult. Even if your utility supports the Green Button data standard, there are still requirements for obtaining and documenting authorization from the customer. Fortunately, UtilityAPI helps make this easy with a service by creating an authorization request that you could send to your customer. Once your customer grants […]
Measurement and Verification (M&V) is a crucial part of energy efficiency project finance, but its high cost, complexity, and lack of transparency have caused many building operators to lose trust. We believe, though, that open source software can make M&V easier, faster, less expensive, and most importantly transparent. If we can fix this weak link, […]
We’ve recently completed two new significant additions to opentaps: Green Button XML and OpenEEMeter. Green Button XML allows you to upload utility billing data, such as interval usage data from smart meters, into opentaps. OpenEEMeter is an open source project that can then help you perform Measurement & Verification (M&V) of your energy efficiency projects […]
