This project builds a blockchain network to calculate emissions from transportation and verify emissions reductions in transportation. It could be used with a mobile app to track your own personal emissions for traveling or transportation and logistics emissions as part of the Supply Chain Emissions Ledger ProjectDecarbonization.
Requirements
Mobile App
Using a mobile phone to track travel is quite complex. Fortunately, there is an open source project called "e-mission" which provides a lot of the infrastructure for it. See "E-Mission Mobile App
...
" below and the paper "e-mission: an open source, extensible platform for human mobility systems"
We could build upon e-mission to create a mobile app which A user-friendly mobile app will capture travel information and integrate with the Blockchain network (see below.) The mobile app could be used by an individual to track their travel, or attached to a truck, ship, airplane, or cargo container to track its transportation. The mobile app could offer useful services in addition to tracking trips and calculating emissions, such as maps for drivers and cyclists, looking for shared rides or bikes, or booking or checking on flights, etc.
Features of the mobile app:
...
Integration with the blockchain network will be via the web socket security wallet on the mobile client.
See our 2021-12-20 Peer Programming Call for a discussion about developing this mobile app and integrating it with the blockchain network.
Blockchain Network
A Fabric blockchain will receive the travel records from either the mobile app or other sources such as shipping manifests (UPS, freight carriers) or employee travel systems (Concur).
...
- Mode of transportation (ie drive, bike, fly, type of car), based on origin, destination, and time of travel to calculate the average speed and verify that this is reasonable given the mode of transportation.
- Fuel use - electronic certificate or token of sources of electricity for EV's or sustainable fuel for aviation and cars.
- Sharing - Simultaneous record of travel from other people on the network to prove you shared a ride.
- Claimed emissions - Programs such as UPS Carbon Neutral or the Delta Airlines Flight to Net Zero involve both reductions and offsets. The blockchain can collectively validate these programs' claimed emissions reductions.
Tokens of Emissions Reduction
Tokens of emissions reduction from travel will be issued by a DAO. The DAO will vote on:
...
The DAO can issue tokens for verified travel reduction.
...
E-Mission Mobile App
NREL OpenPath (formerly e-mission) provides a mobile app which captures travel information and send them to a server.
Here are some screenshots of what it looks like:
You can try it out yourself by downloading this APK and installing it on an Android phone:

Once you download it:
- Turn off Power Saving Mode in your phone
- Do not optimize power savings or monitoring for this app.
- When signing in, it will prompt you for an email. You just need a username from our server. Email Si on the Climate-Sig mailing list for one.
See their github issues #693 and #694 for how to set it up correctly, as well as details about how this interesting app works. See this page for how it calculates emissions from travel.
Other resources
This program from the Connecticut Green Bank serves as an example of certifying emissions reductions from electric vehicles.
- The emissions calculation channel (currently being refactored from just utility emissions) will calculate emissions based on the type of travel and distance and store them on Fabric.
- Emissions factors for different types of travel and transportation is available from the data sources of the Supply Chain Emissions Ledger ProjectDecarbonization.
- Calculated Emissions could then be tokenized on an emissions tokens network
- Emissions reduction certification by the DAO Project.
