Emissions: Internal Combustion vs. Rivian R1S


Latest update: July 1, 2022.

To help mitigate the climate crisis, citizens should consider an electric vehicle the next time they purchase a car. I wrote this program to help drivers determine the life cycle greenhouse gases that their current gasoline car emits, and then compare the results with those for a 2022 Rivian R1S electric vehicle, using the EPA’s most recent data (see the footnotes below for links to the sources).

Math doesn’t lie. Nationwide, a gas car would have to average at least 50 MPG to to produce fewer greenhouse gases than a Rivian R1S, yet the current national average is only 25.7 MPG. Moreover, as utilities continue to transition away from fossil fuels to renewable energy, electric vehicles will only get cleaner. In fact, many owners are already going the extra mile (pun!) by charging their electric vehicles with solar panels. Don’t drink the pe'trolls’ Fossil Fool-Aid!

I will update this page as new data become available, so check back again in the future.
