You’ll see the following abbreviations on your Karmic Profile page:

KES = Karmic Environmental Score

This is the relative impact that your Karmic Projects have had on the environment.  Negative scores indicate that your projects are NOT sustainable and that you are going to need to find a way to offset the environmental impacts of your project such as buying CO2 offsets, using more recyclable or reused supplies, and reduce the use of fossil fuels.  One great way to help most projects is by avoiding the use of fossil fuel based power generation.  If you can use grid power and ensure your grid service is from sustainable power, that would be the first choice.  The next choice would be to look into using greener power sources such as batteries charged with green power, solar power, or even hydrogen fuel cell power, which has recently started to be more accessible.  Remember that by getting used parts and supplies through the Karmic Project Foundation, all of those purchases will generate an offset to your KES since they prevent things from going to a landfill or the use of new materials to produce another item.
