How much will the carbon tax cost you? Use our calculator to find out.
What will the carbon tax initiative, I-1631, cost you if it passes? We’ve created a carbon tax calculator to help you find out.
The tax begins at $15/metric ton of CO2 in 2020 and increases by $2 a metric ton each year plus inflation. These calculations use the lowest cost, $15/MT.
You will need three pieces of information:
- How much gasoline does your family use each year in total gallons
- How much natural gas does your home use monthly or annually
- How much electricity does your home use monthly or annually
Also, you can select from three utilities: Puget Sound Energy, Avista, or the Washington state average. Each utility has a different mix of energy and the cost depends on that mix.
You can find the data on your monthly utility bill. In Washington state the average usage is:
- About 625 gallons per vehicle per year (this amounts to a fill up about once every 9 days)
- About 650 therms (W. Washington) and 790 therms (E. Washington) of natural gas per year
- 11,500 kilowatt hours of electricity per year
If you have questions about the calculation, e-mail me at firstname.lastname@example.org.
Thanks to the Whitworth University computer science department and student Jordan Bone for helping put this together.
