EmissionFactors.com taps into the most powerful environmental database in the world, powered by Ecometrica. Over the years, we've spent thousands of hours searching for and cataloguing emission and conversion factors and still do it on a regular basis. The accuracy of our data is very important to us.
Now, we share our database publicly via the EmissionFactors.com portal. We decided it was about time someone launched a service that gives spreadsheet users a one-stop shop for emission factor research.
