Introducing ‘Webstripes’

The climate stripes created by Professor Ed Hawkins are one of the most effective pieces of communication design I’ve ever seen.

They work so well because they make an invisible problem visible, helping people to immediately understand climate change in a simple and visually appealing way.

Decarbonising digital services

Digital services have a significant and growing environmental impact, driven primarily by the energy required to store, transfer and render data.

Unfortunately, most of this impact remains invisible to the people who are responsible for them.

I’ve been working on an approach called ‘decarbonising user journeys’ to make this impact easier to understand and manage.

The principle behind it is simple.

Reduce the weight and energy demand of the pages that make up key digital user journeys in order to reduce the overall environmental impact of the service.

Using tools such as the Website Carbon Calculator, you can calculate the energy efficiency of individual pages and identify where the biggest problems are.

I’ve been experimenting with ways to visualise this information using energy efficiency ratings that people are familiar with from everyday things like household appliances to rate web pages.

It worked reasonably well but I kept thinking about the simplicity and effectiveness of the climate stripes.

It got me thinking, could a series of stripes be used to visualise the energy efficiency of a digital user journey?

Introducing Webstripes

I’ve been working with the awesome Jon Gibbins to automate the capture of website energy efficiency data and used some of this data to create the website equivalent of the climate stripes.

I’ve called it Webstripes.

Each stripe represents the energy efficiency of an individual web page that makes up a digital user journey.

I liked the impact of my first attempt but it’s not great if you’re colourblind so I created a better version that more clearly communicates the relationship between page weight and energy efficiency and doesn’t rely on colour to convey information.

Shorter stripes represent lighter, more energy efficient pages.

Longer stripes represent heavier, less energy efficient pages.

Environmental impact data is often too complicated and confusing.

People can’t (and won’t) act upon things they don’t understand.

I’ve seen first hand how powerful simple visuals such as experience maps can be within organisations to drive positive change.

Webstripes can help teams to quickly identify problem areas and help them focus their optimisation efforts to make the reds turn green.

Beyond human centred design

Human centred design helped make digital services useful, usable and desirable.

But if we only optimise for people, without considering the wider impacts of our work we risk designing services that are harming the environment.

Our work must now focus beyond human centred design.

Learning how to do this effectively has to be our priority given the climate emergency and proliferation of digitisation within our every day lives.

I’ll be sharing more about this in my talk on ‘Beyond Human Centred Design’ at UX Scotland in June.

And if you’d like me to create Webstripes for your own user journeys, do get in touch.

Decarbonising the Premier League

Earlier this year, Richard Masters , Chief Executive at the Premier League, launched their Environmental Sustainability strategy.

It focusses on three key priorities :

  1. To become net zero by 2040
  2. To support decarbonisation across the league
  3. To raise awareness of climate change

As a football fan and someone on a mission to reduce the environmental impact of the internet this caught my eye.

Many people don’t realise that the internet is responsible for higher global greenhouse gas emissions than the aviation industry.

With over 60% of the global population now spending 40% of their waking hours online, this trend is set to continue leading to predictions that the internet will be responsible for 40% of global greenhouse emissions by 2040.

Given these alarming figures I wonder if the Premier League are prioritising or even aware of the potential carbon footprint of the club websites in relation to their decarbonisation objectives?

Club websites serve huge global fanbases and are typically content heavy, particularly with images and videos which are energy-intensive to store and transfer to users’ devices.

Multiple this usage across the 20 Premier League club websites and the cumulative impact of millions of page loads results in a significant carbon footprint.

So this all got me thinking…

Who would win the Premier League if the winner was the club the smallest website carbon footprint?

I chatted to the folks at Cardamon about the idea and they kindly offered evaluate the websites using their carbon calculator.

To make the results comparable, we calculated the carbon footprint of 10,000 visits to the homepages of each site (clearly the footprint of the entire websites will be significantly higher).**

And the results are in!

A league table containing all of the premier league football teams ranked by the carbon footprint of their club website. The club with the lowest homepage carbon footprint is Manchester City and the club with the largest homepage carbon footprint is Ipswich Town. The table show the carbon emissions and energy usage from 10,000 visits to each of their homepages and whether they are using green hosting or not.

The full ranking (best to worst) is Manchester City, Everton, Arsenal, Chelsea, West Ham, Manchester United, Wolves, Southampton, Crystal Palace, Liverpool, Aston Villa, Fulham, Leicester City, Bournemouth, Brighton, Newcastle United, Spurs, Brentford and Ipswich Town.
The Premier League of website homepage carbon emissions

So hats off to Man City for having the lowest homepage carbon footprint, but let’s face it they’re the best of a bad bunch.

It’s no surprise that Ipswich are anchored to the bottom of the table given their hefty 29 MB homepage.

If the Premier League are serious about meeting their sustainability goals then decarbonising club websites must be a key part of their strategy.

Even a tactical focus on switching them all to green hosting would make a huge difference and feels like a simple tap in.

The benefits of low carbon websites

The benefits of low carbon websites extend far beyond the environment.

Low carbon websites are deliberately designed to be as simple as possible making them easier to use, download faster and available to more people.

Their simplicity means they are more efficient, effective and use less energy – making them better for people, performance, planet and profit.

So what about the carbon footprint of your own website?

How much do you know about the carbon footprint of your websites and what is being done within your organisation to minimise it?

What risk does ignoring your digital carbon footprint pose to your reputation, values or wider sustainability goals?

I’d argue a very significant one.

The climate crisis demands that every responsible organisation should make a plan to minimise the environmental impact of their digital product and services, but many simply don’t know where to start.

I’ve created some simple and practical free tools that will help get the ball rolling:

It would be wonderful to see a very different story in the table next year, seeing the reds, blues and lilywhites becoming greener.

I hope this helps to nudge the clubs in the right direction to minimise the environmental impact of their websites.

If anyone needs advice, help kicking off or hands-on support with any of this I’m here to help – just drop me a line.

Simple steps to decarbonise your user journeys

I was shocked to learn that internet is responsible for higher carbon emissions than the aviation industry.

It’s vital that we minimise the environmental impact of our digital products, but knowing where to start and what to do can feel overwhelming.

To help accelerate change, I’ve scoured the W3C Web Sustainability Guidelines and extracted some key priority areas that I’ve turned into a simple action plan to help you decarbonise your user journeys.

It doesn’t cover everything but will to help you get off and running.

This is about progress over perfection after all.

So here’s the plan:

  1. Benchmark your carbon footprint
  2. Switch to a green hosting provider
  3. Offer the best possible user experience
  4. Make everything as simple and lightweight as possible
  5. Focus on doing more good than harm

1. Benchmark your carbon footprint

You need to benchmark your emissions to get a clear idea of how your journey is performing, where the problems are and to help you plan and prioritise your decarbonisation efforts.

How?

  • There are loads of great free tools you can use like The Website Carbon Calculator, Ecograder, Cardamon and Google Lighthouse to benchmark useful data such as your carbon footprint, performance, page weight and carbon rating.
  • I’ve mocked up this simple dashboard to demonstrate how you can visualise this benchmarking data to help you to see how well your user journey is performing and identify where you need to focus your decarbonising efforts.
A table showing the results from various online tools such as Google Lighthouse, Website Carbon Calculator and Ecograder that calculate benchmarking data such as carbon footprint, performance data, page weights etc from a set of web pages that make up a user journey.
Your benchmarking results will help you to understand your impact and prioritise your decarbonising efforts

2. Switch to a green hosting provider

The level of pollution from your user journeys will depend on the carbon intensity of the energy that is used to power them.

Switching to a hosting provider that is powered by green energy will help to make your corner of the internet fossil-free.

How?

3. Offer the best possible user experience

When things are easy to use we spend less time doing them, using less energy as a result.

By ensuring user journeys are useful we can justify the resources we use to create and operate them and by making them accessible we ensure everyone has access to them.

Your objective should be to make your user journey as useful, usable and accessible as possible.

How?

  • Conduct regular user research on a range of devices to ensure you understand user needs and how and where you need to improve your user journeys.
  • Aim for people to be able to successfully complete their tasks first time around without wasting time and energy through errors, needing support or spending more time than necessary trying to do what they are trying to do.
  • Aim to meet the highest level of accessibility compliance possible to ensure the widest possible audience can access and benefit from your service.
  • Remove anything that is distracting or detracts from people being able to complete their tasks and do everything possible to help them.
  • Use established design patterns that people will be familiar with and already know how to use.
  • Always write in plain English and check the average reading age you are writing for (in the UK it’s between 9-11 years old).

Useful resources:

4. Make everything as simple and lightweight as possible

Lightweight pages download faster and consume less energy to be stored and transferred across networks. They will work better in areas with poor connectivity and for users with older devices helping to maximise the amount of people who can access your service during challenging circumstances.

Fundamentally people won’t tolerate slow page loading times and if forced to wait will simply go elsewhere.

How?

  • Reduce – Be ruthless and remove anything (content, pages, scripts, images, features etc.) that isn’t providing any value by questioning the purpose of every element (use these questions to help you).
  • Replace – Look for alternative ways of communicating the same information using lighter weight alternatives. Be particularly careful with using video and AI given how resource intensive they are.
  • Optimise – Ensure that assets such as images, videos, fonts, downloads, animations are suitably optimised to minimise their file size.
  • Think ‘Mobile first’ – Adopt a ‘mobile first’ mindset to help you ensure that people using the smallest screens with poor network connections can still access, use and benefit from your services.

Useful resources:

5. Focus on doing more good than harm

Sustainable services are those that do no harm. We must do better. We should aim to provide regenerative services that do more good than harm and result in a net positive impact on the economy, society and the environment.

Being open about your digital sustainability progress and honest about your successes, failures and plans builds trust and helps your customers to make informed choices about the impact of using your services.

The image show a graph with impact on the y axis (from low to high) and time on the x axis. It shows how organisations can move from a position where they are unsustainable (doing more harm than good) to being sustainable and then ultimately regenerative, where they are doing more good than harm.
The journey towards regenerative design

How?

  • Ensure your business models, values and organisational strategic intent is focussed on acting the best interests of people and planet.
  • Be respectful of people’s time, energy and the effort required of them to use your services.
  • Ensure people are in full control of their data and are only asked to share the minimum amount of personal information possible.
  • Ensure no unintended consequences occur as a result of your service.
  • Don’t use manipulative or deceptive patterns and seek to minimise the time and mental effort required to use your service.
  • Publish a digital sustainability statement that clearly communicates your impact, the work you’ve done to reduce it and the improvement areas that you will be working on next.
  • Add a Website Carbon Badge to to automatically calculate and display the carbon emissions of each page or your website.

Useful resources:

Remember, the spirit of the approach is progress over perfection, so start small and focus on continuous improvement.

Your digital product will never be perfect, but every change you make will help to minimise your environmental impact.

Decarbonising User Journeys

I’m on a mission to help reduce the environmental impact of the internet.

I’ve created a new approach that I’m calling ‘Decarbonising User Journeys‘.

It has been designed to give you a pragmatic method to help you deliver faster, simpler and more effective user journeys that have less impact on the environment.

I’m over the moon to launch it here and would love to hear your feedback, questions and experiences of using it. 🚀

This presentation tells the story of why we need to urgently decarbonise the internet, the thinking behind the approach and explains how you can start to decarbonise your own user journeys.

It is deliberately simple, jargon free and designed to give digital professions the tools they need to take positive steps to accelerate change.
