Frequently Asked Questions

Questions we get from time to time about EcoPing.

What is a ping?

A classic internet ping is the time it takes (in milliseconds) for a small data set to be transmitted from your device to a server on the Internet and back to your device again.

Normally you ping a website multiple times per day to see if it's still online. Inspired by this we super charged the simple "ping" to gather lots of data about the website and it's impact. This is how we calculate website carbon emissions.

Can I check a website for free?

You sure can! Once you've signed up to EcoPing you can add a site to your dashboard. We will "ping" or check this site every day so you can see your website carbon emissions over time.

How many websites can I check?

It depends what plan you signup for but for example our Agency plan allows your to check/ping as many as you want!

  • Free - 1 site and 1 sub-page
  • Basic - 3 site and 3 sub-page
  • Pro - 5 site and 5 sub-page
  • Agency - Unlimited sites and Unlimited sub-pages

Checkout our Pricing page for more features.

Can I check sub-pages?

Yes you can! When you add a new site to EcoPing in your dashboard view you can add pages within your site, on our Agency tier this is as many as you want.

I've add a site to EcoPing but the ping failed, what's happened?

First off if this has happened, please get in touch and we can see what we can do. The top 5 reasons are:

  1. Bad domain name
  2. A non 200 response (around 5% of failed pings)
  3. Transient network failure
  4. Our IP is marked as bot by Cloudflare or another CDN
  5. Your site is so big/bad that Lighthouse crashed

How do you calculate website carbon emissions?

We use the latest and greatest calculations from Sustainable Web Design. With a few changes...

  • Dynamic grid intensity - We don't use the hard coded 475g/kWh. Getting this value from live grid data from around the world. Giving a better reflection the how data centers and websites are powered.
  • Green hosting - We calculate how green your website's hosting is by looking at where your websites resources come from and the energy production in those countries.

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.

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 integrate each report with live grid data so we can see where in the world your resources come from and what the energy production is like.

Giving a clearer idea of how green web hosting is.

Can I ping/check all my website's pages?

Yes you can. On our Agency tier you can add as many pages to a site check as you would like.

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.

Do you account for frontend frameworks?

No we don't. SWD calculations uses transfer size which is nice and easy to get and publicly available.

Do you account for backend services?

No we don't. EcoPing is a non-invasive tool that works on public available data based off the frontend transfer of a web page. Good to note because of this and how tricky it is to gain access to this granular data, estimates for the entire full-stack application impact will be vastly higher.

We do have some thoughts on how to do this though so please do get in touch if this would interest you.

I have a client that would like help calculating their carbon emissions, can you help?

We sure can. Please send us an email to: and we can help.
