There are quite a few apps and services selling personal carbon offsets, but most of them today rely on general surveys with questions such as "What kind of home do you live in?" or "How much do you drive per year?"

By combining data sources from Operating System for Climate Action, such as utility bills, driving records, travel data, and other sources of large carbon emissions, we could build an app which calculates a person or family's carbon emissions from actual data.  This could then be linked to carbon offset purchases, either on a blockchain or separately, to offset emissions.

  1. Hi WG Community, do you think IOT has some role to play in tracking "Personal' carbon offsets ?

    I saw Vehicle Zero Emission Travel Network Project project that does the tracking using the mobile apps and is specific to vehicle emission tracking. Just a thought, when you say Carbon tracking do you mean that also includes other Green House Gases like CH4(Methane) etc?

    As per wikipedia, there are several ways to reduce one's greenhouse gas footprint, choosing more energy efficient eating habits, using more energy efficient household appliances, increase usage of fuel efficient cars, and saving electricity.

    Using IOT, the household device energy consumption can be traced and in turn can be used to calculate the carbon footprint per device. And this information can also be recorded in the Fabric ledger to further integrate with vehicle emission that will create a more personal accounting on carbon footprint per house.

    Elaborating upon my thought, using the above diagram, Each device(Device1 & Device2) data can be upstreamed to the blockchain. Same data can be used by an individual to keep an eye on her carbon footprint for each device using an app and save energy by decommissioning the less efficient devices (mostly old). Another use of this data can be in conjunction with the other emissions data for net emission accounting.

    1. Yes, by carbon tracking we mean all greenhouse gases (GHG) including CO2, methane, etc. Measured in their greenhouse contribution in Metric tons of CO2 equivalents (MtCO2e).

      Yes, definitely.  Actually we’ve done so more work on building energy data collection with opentaps SEAS ( which is part of the current demo for utility emissions channel.  My long term idea is to use the blockchain to tie together a network for doing exactly what you’re talking about, and without a central authority.

      1. I would like to be able to rate a product by Carbon Intensity at the point of sale. This could be done with a barcode.
