Frequently Asked Questions

EmissionFactors.com is your one-stop shop for compiling your organisation's carbon assessment. Putting together these assessments can be time-consuming, due in part to the laborious task of having to trawl the Internet hunting for the right emission factors to fit your data. EmissionFactors.com puts every emission factor conversion at your fingertips, in an instant.

An emission factor is a value used to convert activity data (e.g. the amount of electricity used or the distance travelled by petrol car) into the amount of greenhouse gas that activity has emitted. They are a critical element of compiling any comprehensive environmental assessment, as without them it is impossible to assess the GHG impacts of your activities.

You can find detailed pricing information on our Pricing page. However, for a limited time, EmissionFactors.com is free to use on a limited basis, with no sign-ups required! Just enter your location, pick your activity, and you're off.

EmissionFactors.com is an invaluable tool for anyone tasked with compiling their organisation's greenhouse gas assessment. Emission factors and conversions are available instantly by way of one simple search, not Internet trawling. Plus some of our advanced packages allow you to update all your greenhouse gas accounting spreadsheets automatically using the cleverness of the EmissionFactors.com API.

Some of the information you can find within EmissionFactors.com is freely available elsewhere on the Internet if you look hard enough. As a team of experienced GHG accounting professionals with over a thousand assessments under our belts, we know how tough it can be to find new factors and understand the amount of work that is needed to keep factors up to date. We have created EmissionFactors.com so that you don't have to spend hours searching the Internet for the factors you need - they're all right here under one roof, and available to you right now. You will also be able to access all of Ecometrica's proprietary emissions factors and data models. Why would you go anywhere else?

EmissionFactors.com is powered by the geeks at Ecometrica (www.ecometrica.co.uk). We are a group of experts in greenhouse gas (GHG) accounting, ecosystem services, climate change policy, remote sensing, and web based programming, with unrivalled experience in the development and application of the major standards for greenhouse gas accounting and ecosystem change measurement.

Between us we’ve spent many thousands of hours searching for and cataloguing emission and conversion factors. We use the resulting database in our work every day, whether it be providing carbon accounts to our clients, accrediting work our clients have carried out themselves, or powering our online carbon accounting package Our Impacts.

So we thought it was about time to launch a service that gives those spreadsheet users out there a one-stop shop for their emission and conversion factor research. Best of all, because we are constantly maintaining this database, you’ll always stay up date.
