The Open Offsets Directory

The voluntary carbon offsets market has long been held back by a lack of transparency.  We believe the solution is a decentralized data common built with blockchain that encourages market participants to share their data.

A prototype of this concept using live data is now available at

If you’re involved with the offsets market, please join our study as an expert.  Start by completing this online questionnaire, and let us know if you’re available to be interviewed.

We’re Live!

Our Hyperledger Fabric utility emissions channel and Ethereum emissions tokens network have now been deployed to production on AWS Kubernetes and xDai Layer 2 network.  It will allow users to tokenize emissions based on real utility billing data and (coming soon) offset their them through a DAO.

Emissions Tokens on Blockchain

Take a look at an emissions tokens network, which allows emissions auditors, REC dealers, emissions offsets dealers, and consumers to tract emissions and trade offsets on an Ethereum blockchain.

This is an implementation of the emissions tokens network, the second part of our Operating System for Climate Action.

From Energy to Emissions

This demo shows how we’re taking utility bills from Green Button XML and storing them on a permissioned data channel with Hyperledger Fabric.

This is an implementation of the audited emissions data channel, the first part of our Operating System for Climate Action.

To try it yourself, see our blockchain carbon accounting project on Github.


M&V Model Chart Example

Make M&V Believable Again

opentaps brings together data from utility meter and building equipment in one platform.  Advanced statistical models are included with opentaps and amazingly easy to build.
The result: Building managers, ESCO developers, and contractors all have access to the same data and models.  They can all see building-level energy use and detailed equipment performance to understand and verify energy savings.
By making both data and software openly available, M&V can bring together all parties and achieve greater energy efficiency, instead of being a source of disagreement and mistrust.  Read more about how we’re doing it.

Turn Energy Data into Insights

opentaps is the one platform for all your energy data, from utility meter readings to Building Automation Systems to solar panels and batteries.  

opentaps SEAS is compatible with industry-standard protocols, including Green Button XML, BACNet, and MODBUS protocols.
