In this post, I want to look at the two different carbon accounting models used for estimation, and in what scenario you might use one over the other.

Thoughts and advice on how to build low-carbon, environmentally friendly websites.
In this post, I want to continue building out an incremental model, but rather than focusing on emissions calculations I want to create a model to estimate energy use.
In this post I will look at an possible alternative approach to calculating the emissions of the server (data center/hosting) segment for websites using the methodology outlined by Cloud Carbon Footprint.
CO2.js v0.13.0 brings the latest average grid intensity data from Ember into the library, as well as expands the number of countries for which average grid intensity data is available.
In early May, 2023, the WebPageTest (WPT) team shipped a new feature to the tool. They called it Carbon Control, and boy oh boy was I excited to see it finally land.
This post captures my thoughts on the use of data transfer in website carbon emissions calculcations, and what the future holds.
A recent post by Adrian Cockcroft raised some sensible counter arguments for why chasing green energy usage for cloud compute might not always be the most climate friendly solution.
A conversation from the ClimateAction.Tech community about self-hosting a website on a solar powered Raspberry Pi.
CO2.js is one of the tools we’ve created to help developers drive the transition to a fossil-free internet. This article will explain the concepts behind CO2.js, it’s uses, and when other tools might be better options to consider.
CO2.js v0.12.0 introduces the ability to customise the figures used in carbon emissions calculations when using the Sustainable Web Design model, paving the way for more case specific carbon emissions estimates.
Building carbon awareness into products is an important strategy to in the challenge to develop a more sustainable future. In this post, I cover how I used Cloudflare Workers and real-time data to make this website carbon aware.
Existing models for website carbon emissions are good for reaching a ballpark figure of website CO2 emissions. This post goes into some ways to generate more specific, accurate emissions estimates.
I’ve been thinking about how we can drive broader change to make the web more sustainable and performant. As I’ll get into, I believe a large part of that comes from the defaults set by the tools and services we use.
As COP27 approaches, I thought it would be “fun” to take a look at this year’s COP homepage. How does it do in terms of website sustainability?
Measuring the carbon emissions of websites and apps is no easy thing. Most tools use the amount of data being transferred to calculate the overall emissions. But to get more detailed, relevant results we need to go beyond just data transfer.
The v0.11.0 release of CO2.js introduces a change to the default carbon estimation model, as well as including global average and marginal intensity data for the first time.
Uploading and downloading the bits and bytes that make up the internet uses a lot of electricity. Breaking the internet down to a systems level, data transfer over networks accounts for an estimated 14% of the web’s total electricity consumption.
I share some thoughts on the new proposal put forward by the MS Edge DevTools team for a new “Sustainability” tab to be included in the Edge browser’s DevTools.
The v0.10.0 release of CO2.js introduces an easier way for developers to switch between the different carbon estimation models that are available in the library.
Knowing the carbon intensity of the electricity grids in which code runs can allow developers to make informed decisions about where/when to run their code.
“Are my third parties green?” is an online tool that checks the sustainability of third-party requests made by any web page. This post provides some insights into how it was built, and what other features are planned.
By using less power, using green power, and buying from green suppliers businesses and individuals alike can reduce their carbon footprint. How would we go about applying this same thinking to website performance and sustainability?
Everyone wants to make sure their website's Core Web Vitals are up to standard. What if we told you that some of the very things you'll do to improve your site's Core Web Vitals can also help make it more sustainable!
As our thirst for data, connectivity, and content grows, so does the portion of global carbon emissions attributed to the internet. In this post, we'll take a look at the steps frontend developers can take to make sites more efficient and better for the planet.
What's the link between a faster website and climate change? In this post I'll explain how you can help the environment by focusing on website performance.
