Frequently Asked Questions
How do you calculate website carbon emissions?
We use the rather wonderful carbon API from WebsiteCarbon. The only difference is we don't check based off green certificates. We calculate where your resources come from and the countries that they are hosted in.
These calculations are based of the 1.8 kWh/GB from a 2017 study On Global Electricity Usage of Communication Technology: Trends to 2030 and you can read up more about calculating website carbon emissions on the WholeGrain Digital blog... thanks Tom (cracking article)!
Why don't you check for green certificates?
We think it's a bit too easy to simply buy a certificate and become a green host. For us it's about where the resources that make up your website come from, what's the energy production like in those countries that run those servers.
Take a look at Electricity map to give an idea of where your power comes from and what is being produced.
When I look in dev tools some values are different to EcoPing, what's going on?
EcoPing gets this information in a very similar way. For us though we wait until networkIdle2 in Chrome has loaded all the resources, and then wait until there are no more than 2 network requests for 500ms and take the values then.
Aren't many cloud services already renewable & carbon neutral?
Companies like Amazon and Google have committed become carbon neutral by 2025 (Amazon) and 2030 (Google) . Current commitments for both seems to be based on renewable energy credits and offsets. There are datacentres running of renewable energy for both Amazon & Google, or like one we use from Microsoft Azure that's based in Washington state which runs off renewable hydroelectric power.
I have green hosting but EcoPing says I don't, why is this?
We don't look at your specific hosting provider. We intergrate each report with live grid data so we can see where in the world your resouces come from and what the energy production is like.
Giving a clearer idea of how green web hosting is.
Can I get my entire digital carbon footprint for all pages?
Yes you can. On our Agency tier you can add as many pages to a site check as you would like. We haven't automated this as some sites have millions of pages, so you can add the most popular pages first.
By adding 10 pages we think you can get a good idea what of your entire website carbon emissions.
If you would like us to calculate this for all of your site, please send us an email and we can help.
I have a client that would like help calculating their carbon emissions, can you help?
We sure can. Please send us an email to: firstname.lastname@example.org and we can help.
