We've measured the digital carbon emissions of over 1000 sustainability-focused website homepages and want to share the results with you!

The emergence of sustainability-centric companies, initiatives and authorities are essential in order to successfully combat the issue of climate change. However, the increasing global online presence means that even sustainability-driven businesses have a digital carbon footprint. Digital carbon is an underreported aspect of global greenhouse emissions, despite accounting for as much as 4%.

In light of this, we’ve used our website carbon calculator (check out how it works 

) to measure and rank the websites of more than 1000 of the world’s sustainability-focused websites by their digital carbon emissions in our biggest study to date! The problem of digital carbon is often not taken into account by businesses when measuring their sustainability, so we want to raise awareness of the fact that their digital activities have an impact too.

Below we have showcased the 25 lowest carbon websites we measured. They’re using green servers, minimalist design, and tight coding practices to achieve the top marks in our research.

Each website listed below in our top 25 is eligible for the Greenpixie low carbon award to put on your site!

Greenpixie's Top 25 low carbon sustainability-focused websites 

The splintered approach of major cloud providers towards digital carbon is threatening to undermine accurate ESG reporting for multi-cloud setups. What can we do?

There is an increasing ethical and legislative demand for organisations to report on their digital emissions. Digital carbon now accounts for 4% of total carbon emissions around the world and, shocking as this is, this realisation has coincided with a change in computing habits which makes understanding that figure a tricky task.

Modern businesses have been adopting cloud computing en masse.

The traditional model of privately owning physical servers, or renting a permanent portion of a data centre, is now expensive, outdated and unnecessary. Cloud computing offers a flexible and far less expensive alternative to this, retaining the benefits of the private server approach, while almost all of the heavy lifting is carried out by the cloud provider - usually trusted and industry-leading brands, like Microsoft, Google or Amazon.

Advantages of cloud computing, besides lower maintenance and setup costs, include improved general performance, a near-limitless capacity for storage, and a global reach that enables data to be stored in different locations around the world, closer to the end-users.

Best of all, as the cloud provider creates a virtual machine on the physical server where your data is stored, you won’t notice any difference between the cloud computing experience and running your own server.

That’s why, for many, the move to cloud computing has been a no-brainer. Indeed most modern companies are unlikely to have ever operated another way.

Data is hard to find and calculations don’t match up

Unfortunately, in a time when businesses need to take responsibility for the greenhouse emissions caused by their digital activity, cloud computing has actually made this harder than in past models.

If the digital sustainability revolution had begun twenty years ago, companies could have easily incorporated the electricity used to run their onsite servers into their ESG reporting. But now, this information is nearly impossible to access. Usage data is hidden amongst the opaque processes of AWS, Microsoft Azure, and Google Cloud and, even when accessed and organised, usage data is not easily transformed into emissions data.

What are cloud providers doing about this? In short, not enough.

AWS, Google Cloud and Microsoft do have tools that aim to give an estimate of a user's digital carbon footprint, but these have been considered incomplete and overly general by many users. (https://thestack.technology/aws-carbon-footprint-tool/)

Moreover, their calculations and methodology are all quite different, with little to no transparency on how they reach their results.

To make matters worse, many organisations are now moving towards multi-cloud setups, meaning their applications are split across a number of different cloud providers.

This approach has natural benefits, allowing developers to play to the different strengths of the providers across applications, and is also the natural result of a split market, with different teams and individuals gaining familiarity with certain providers, leading to different parts of the same company splintering between them.

But this convenience does not extend to understanding cloud emissions. In fact, multi-cloud computing is even more of a headache to report and manage.

As the three major cloud providers drag their heels over cloud emissions while travelling in different directions regarding calculations and methodology, any data customers can get their hands on will prove tricky to reconcile into a coherent dataset. Not to mention multi-cloud setups involving the many other emerging cloud providers, which may further complicate the picture.

Without easily accessible, coherent data from all cloud providers, digital reporting is suffering - and this affects the ability of organisations to truly achieve their Net Zero pledges.

Untangling the emissions of multi-cloud setups with Cloud NetZero

We’re making it our business to build a software tool that can easily access and organise usage data from all cloud providers at once, before using our academically researched carbon algorithm to uniformly produce cloud emissions data that can be presented simply in one easy-to-understand dashboard.

As cloud computing continues to develop, there are certainly more and more possibilities opening up for users. However, with the climate crisis and necessary legislation looming, the puzzle of cloud emissions data is one that we’ll benefit from solving sooner, rather than later.

The growing trend of multi-cloud computing setups (and what this means for Net Zero)

An article by our partners over at Keep Cool about this importance of digital carbon

"If you cannot measure it, you cannot improve it." - Lord Kelvin


Two newsletters in a row feature this quote. This email is about Greenpixie, a company whose mission is to lead the world to digital sustainability.

, is the one who actually put me on to the quote above, as it’s become a bit of a Greenpixie motto.

In Tuesday’s email, we discussed the SEC’s new proposed reporting requirements, which would require all public companies in the U.S. to report Scope 1 and 2 emissions and presumably that would encourage many companies to report their Scope 3 emissions as well.

Scope 3 emissions are those that aren’t directly related to producing or using electricity or heat. E.g., moving goods across the world if you’re Amazon.

What’s another big component of companies’ Scope 3 emissions that doesn’t always meet the eye the same way Amazon delivery trucks in your neighbourhood might? It’s the electricity required to operate (and cool) the massive data centres that make it possible for me to write a draft of this email in a document that auto-saves every 4 minutes so I don’t lose my progress.

For tech companies, emissions from their data centre operations are likely a considerable contributor to their overall emissions number. Even globally, emissions from digital operations (data usage, electricity, cloud computing, websites and internet systems), which Greenpixie refers to as ‘digital carbon’, are hard to ignore.

Smog and smokestacks over Singapore (more on Singapore later)

By some estimates, digital carbon emissions amount to 

3-4% of all global greenhouse gas emissions

 - comparable to emissions from the aviation industry. Two trends are set to potentially inflate those numbers. For one, in case you’ve somehow missed all the conversation and hype surrounding the ‘metaverse’ in the past year… then a) congrats, you’re pretty unplugged and b) companies like Facebook Meta are betting the house that we’re all going to spend even more time online in the future (somehow?).

Secondly, as John and I discussed in the podcast we recorded (also live today (

, which has held relatively strong since 1965 when it was postulated, is about to flatten out. Moore’s Law essentially stipulates that the computational power of computer chips doubles every 2 years and that they get cheaper at the same time.

This has allowed computing capacity to skyrocket while also cutting the required energy for a baseline level of computation. It’s the reason the computers that used to take up an entire room now fit in your pocket.

, then we start losing the benefit of crazy efficiency gains as we try to keep up with demand for more and more computation. Which would also mean more energy usage to power whatever metaverse we’re all hanging out in 5 years down the line.

Even if quantum computing comes to the rescue and renders this specific concern mute, John sees digital carbon emissions headed for 10, even 15% of global emissions in the coming decade. Time to start figuring out a plan to tackle that!


Today’s email and podcast release also have fortuitous timing. Greenpixie announced their new product Cloud NetZero this week. It concentrates on making it seamless for companies to understand their emissions footprint from their cloud operations, starting with the three largest cloud providers. In their own words:

"Our tool demystifies the environmental impact of cloud computing."

Interested in checking out their MVP for your business? Greenpixie is accepting a limited number of beta users to test Cloud NetZero. Word on the street is beta users will receive future discounts and priority access to new features too - 

The concept of the ‘cloud’ was admittedly still murky to me a month ago. And this is a bit of intentional sleight of hand, the ‘cloud’ abstraction draws our attention away from the massive data centres required to make what looks like magic to those of us who aren’t computer engineers happen.

To be sure, data centres are hungrily eating up real estate globally. So much so that countries like 

 to stop all new data centre development, in part because of how much of the grid’s capacity they absorb.

Especially in light of regulatory tailwinds, like the SEC’s planned requirement for companies to report on Scope 3 emissions, companies are going to need solutions like Greenpixie’s to understand their digital emissions before they can think about ways to reduce them.

Greenpixie can help companies regardless of which of the three major cloud providers they work with, be it AWS, Google Cloud, or Microsoft Azure. Under the hood, their calcs involve a combination of academic research, understanding local grid mixes where data centres operate, and significant technical facility with the data centres’ entire value chains.


To learn more about exactly how their software it works, you can:

Listen to our recent podcast recording with CEO John Ridd (

Enjoy a 90 second run-down by CTO Will Tinney (

Medium-term, Greenpixie is also considering how to become an engine for decarbonization, not just for assessing and reporting on digital carbon emissions. This’ll be an interesting question I'm keen to track with them over the coming months.


If the grid mixes where data centres operate were composed of 100% low-carbon solutions, digital carbon wouldn’t be a thing. Since that’s a long way off in most places, there are concrete things data centres and the clients that use them can do to reduce emissions. For one, data centres are starting to enter into long-term Power Purchase agreements with independent renewable energy providers, often specifically because their clients are vocal about their desire to see data centres’ operations 

On the most advanced end of the spectrum, there are also companies like 

, who are building out data centre colocation models with renewable energy operations like wind farms or stranded energy assets, like flaring on oil & gas sites, that can be valorized. In these instances data centres aren’t just powered by renewable energy, they actually help renewable energy developers expand capacity by acting as a ‘demand of last resort’, e.g. in valleys where demand from the grid itself for their energy is low.

What's next for Greenpixie? Well... rolling out their MVP. & then a broader go-to-market push. If you're curious about me, then make sure to check out the pod. We go much deeper into what they hope the next 5 years will look like in it.

DIGITAL CARBON - TIME TO PAY ATTENTION

Digital Carbon - Time to pay attention

Discover how our journey has led us from website carbon emissions to the comprehensive cloud computing focus we have today.

From Websites to Cloud: The widening scope of Greenpixie

Greenpixie are bringing sustainability to the digital world through innovative software which helps organisations measure and reduce their digital carbon emissions. The current focus of our research and development is cloud computing (an umbrella within which so much modern digital activity falls) and this coming week will see the exciting launch of our first cloud emissions solution. However, as those who have heard us speak, worked with us, or followed our journey will know, it hasn’t always been this way.

An evolving journey, exploring digital sustainability

In October 2021, our CTO Will Tinney, ran the first URL through our digital carbon calculator tool at greenpixie.com. Needless to say, it wasn’t the last.

Since then we have estimated the homepages of over 16,000 websites, gathering data on a number of industries and reaching out to thousands of organisations, sharing our results. Understandably shocked, many of these organisations have instructed us to then carry out our full digital carbon report on their website, fully auditing their emissions and accounting for all webpages, as well as traffic.

It’s been quite a journey. Our work has got us noticed around the world and we’ve even been lucky enough to share our story at conferences in London and Paris, where we’ve spoken about the importance of measuring website carbon and how to reduce it.

But, despite this positive impact, we’ve always known we can’t stop there.

“If you can’t measure it, you can’t reduce it.” So goes the mantra of our founder and CEO, John, which is why we have worked so hard to provide detailed website reports for organisations to understand their site’s environmental impact. However, digital carbon is not limited to websites alone - far from it.

Email, video calls, gaming, applications, blockchain activity,

 the list really does go on and on, and emissions linked to the cloud are simply ever increasing. So, we thought, for the world to take steps towards true NetZero, all of these sources of digital carbon will need accounting for.

Revealing a comprehensive digital carbon picture and working towards true NetZero

That’s why the last three months have seen a shift in the Greenpixie R&D focus, away from website-specific measurement and reduction techniques, towards the cloud at large. There is an urgent need for accurate, easy-to-use and widely available software which will reveal the true extent of digital carbon emissions. And that’s exactly what the Greenpixie magic is working on.

You can still get a free estimation of any website’s homepage emissions here on our website. And we’re still offering detailed insights through our full reports, which serve as a fantastic introduction to digital carbon for individuals and organisations alike. After all, this is still an awareness issue as much as anything else.

However, with regulation looming, such as the Sustainable Financial Disclosure Regulation, which will make the measuring of digital carbon mandatory for thousands of businesses in January 2023; our focus is no longer limited to websites.

We are excited to make a series of landmark announcements over the coming weeks, including the opportunity for a first crop of businesses to use, test and provide feedback for a first-of-its-kind MVP, which will change the course of the digital carbon landscape.

Take a look at these 5 fintech companies that are tackling climate change in unique and innovative ways in our round-up.

Greenpixie’s Five Innovatively Sustainable Fintechs

How is fintech doing when it comes to environmental sustainability?

Something we at Greenpixie are really excited to see is the rise of 

 fintech – that is, companies that use financial technology to make the world a more sustainable place. There’s a plethora of these out there, from green investment platforms to offsetting to credit cards made of wood. Many are absolutely booming – increasing public and organisational concern for the environment means that eco-friendly financial technology ticks all of the right boxes.

We’ve picked out a few inventive FinTechs below!

 is just unbelievably cool. First up – they make credit cards out of sustainably sourced wood, so you get a fun and ultimately decomposable addition to your wallet. But that’s not all. Every time you make a purchase using Treecard, they donate money to 

 – so every time you buy a flat white or a new book, you’re actually planting trees! Ecosia supports tree planting projects across the planet, which helps mitigate climate change, as well as having more local effects like reducing desertification and reinvigorating water cycles. There is nothing not to love about Treecard!

 might be more in the realms of what you might think of as a traditional fintech, but it’s still an innovative and exciting new platform. This app can be downloaded onto your phone, and provides an easy-to-use platform to invest in sustainable projects. They focus on six areas: clean energy, clean technology, sustainable food, clean water, smart mobility and recycling. They believe in the power of investing being used for good, and we couldn’t agree more.

 is a great resource for investors – it helps you measure the environmental and social impact of your portfolio. It aligns with the constantly changing ESG standards, so it is a simple and helpful way to keep on top of the real impact of investing.

It can be really tricky to work out what the actual impact of investments are, and everyone wants to see their real-world effects. Net Purpose is doing such great work in making sure that investments are really understood and their impacts are quantitatively measured.

is using blockchain technology to solve a slightly different problem: plastic waste. These guys recently won the sustainability award of the year at Fintech100 Abu Dhabi, so you know they must be pretty cool. What they do is incentivise people to recycle plastic waste by exchanging it for tokens, which can either be swapped for money or to help plastic cleanup operations in different areas of the world. 

They use blockchain to make sure this is tracked from when it first gets picked up right through to how it is reused. This makes the whole system very, very transparent - so you and the companies involved can really see what’s happening to the plastic. According to their website, so far they’ve removed a hefty 12 million kilogrammes of plastic from nature - pretty impressive.

 – a carbon accounting service. They help companies measure their carbon emissions, point out where there are major problems, and give suggestions to improve. Crucially, they also include the supply chain of businesses, which is often where major emissions can be lurking, providing a more full and accurate picture. Accounting services like Normative are a real timesaver for businesses, especially with the constantly shifting knowledge and targets that are a nightmare to keep on top of, even to the most keen environmentalists.

It’s great to see these companies, and others, harnessing the power of financial technology for good. What are some of your favourite sustainable fintech companies? Let us know in the comments – we’d love to check them out!

At Greenpixie we help companies measure their digital carbon.

5 Sustainability Initiatives from Big FinTech to get optimistic about 

Understanding your environmental impact - and limiting it where you can - is a responsibility we all share. The biggest players in Fintech face unique challenges and opportunities when responding to the climate crisis - here are 5 examples of them stepping up to the plate.

 has pledged its commitment to reporting and reducing its carbon footprint through a partnership with 

, which provides reporting software to help big corporations reach their Net Zero goals, including Airbnb, Shopify, and Everlane.

The initiative began in September 2021 and has the aim of acting as the company’s first step to reducing its carbon footprint to the minimum possible and, ultimately, achieving Net Zero.

As we often reiterate at Greenpixie, if you can’t measure it, you can’t reduce it. It’s imperative that large businesses with a complex and multi-faceted environmental impact, such as banking services, take practical steps to understand just how big that impact is, so that they can understand how and where to reduce it.

. Anyone that uses Elivs lyrics as the hero text on their homepage is off to a good start in my books.


First, you have the 1% pledge, “committing 1% of all funding rounds to planet health initiatives. Starting with $10M USD towards conservation, mitigation, and restoration efforts for climate and biodiversity.”


Second, and rather excitingly, musician A$AP Rocky has pledged 1% of his investment in Klarna to green causes, with the star having “personally chosen to support the Miti Alliance in Kenya, a grassroots organization that is fighting deforestation.” It’s an awesome partnership and one which gives the cause marketability and a bit of star power - attributes that green initiatives have been accused of lacking in times gone by.

Finally, there’s one line from the Give One mission that really chimes with our belief in sustainable progress at Greenpixie;

“Give One stands behind the vision that human society can and should continue developing and thriving, but equitably and sustainably, within the boundaries of the planet.”

Well said. Of course, we all love progress, innovation and evolution - but we must be mindful with every step we take.

 allows customers to “remove carbon as you grow your business”, meaning they can redirect a portion of their income towards carbon removal technologies.

The initiative is easy to sign up for and requires very little input, beyond the contribution itself, from the customers. The Stripe Climate contributions are managed by the same scientific advisors who allocate Stripe’s own carbon removal funds and, as such, customers can feel confident the impact of their positive action is being maximised.


On top of this, businesses can share their commitment with the Stripe Climate badge, offering a win-win of positive publicity for the business and all-important environmental awareness for the customer.

 initiative which focuses on the empowerment of Visa customers to make more sustainable choices as consumers.

The multi-faceted scheme includes a carbon footprint calculator (which also tells customers how their choice is impacting on the 1.5°C Paris Climate Change Agreement goal), help with offsetting personal carbon emissions, sustainability education, and donations to organisations such as One Tree Planted.

Once again, information is power. Many people struggle to behave sustainably as consumers, simply because it can be unclear which is the green choice and - with hectic schedules, careers and family lives - the environment drops down the priority list amidst the chaos of modern living. Visa’s Eco Benefits scheme looks to address this with the education that will help consumers make informed and conscious choices with their money.

 pledged to use 100 per cent renewable energy sources to power its data centres by 2023, as part of a wider goal to become carbon neutral by 2040.


Of course, we know very well the devastating contribution that energy-intensive data centres are making to climate change, with over 4% of global carbon emissions attributed to digital operations. At Greenpixie, our goal is to create software to measure this impact and offer businesses digitally sustainable solutions.

It is heartening to see a Fintech of PayPal’s stature recognising the hugely significant contribution digital operations makes to their annual carbon emissions. Utilising renewable energy sources to power their huge data centres is an important first step, but of course, we know the Fintech industry - and the rest of the world - have a long journey ahead to achieve digital sustainability.

5 sustainability initiatives in fintech

The hugely energy intensive nature of digital operations means they now account for 4% of all global carbon emissions - read on to discover where and how this is produced.

We hear a lot about how companies and individuals can go greener.

Everyone knows about carbon footprints - and what contributes to them; the cars we drive, the food we eat, the energy we consume… even the deodorant we use. For different reasons, all of this can release co2 into the atmosphere and most people and organisations are looking to reduce their emissions.

But what do we know about digital carbon?

Greenpixie defines digital carbon as ‘The equivalent carbon emissions of an individual or organisation which is produced by internet use or infrastructure.’

When you think about it, it’s no surprise that the internet is pollutive….

Over a billion websites, countless images and endless hours of video, not to mention virtual meetings, live streaming, gaming, applications, intranets, cryptomining and a whole lot more!

With over four billion of us estimated to have access to the internet, storing this data, running these processes and downloading it all onto electronic devices, all requires a huge amount of electricity and is responsible for as much carbon emission as the entire aviation industry.

The climate conversation no one is having

So why is it that even passionate environmentalists don’t seem to be speaking much about this?

It may be that we rarely consider what the internet really is.

We like to speak about information existing all around us, in the ‘cloud’, with no fixed location or tangible physicality - when the truth is a little grislier!

Enormous warehouses, packed full of energy intensive servers are running constantly all over the world - requiring an enormous amount of electricity.

Then there’s the transfer of that data from the server to the end user, which relies on a complex telecoms network, which might be beaming information off of a satellite one minute, or sending it across hundreds of miles of undersea cabling the next.

Once that information is with us, it must be displayed on our electronic devices, which - as we all know too well - require constant power, and regular charging!

All of this basically equates to a lot of coal in the furnace and a lot of environmentally UNfriendly fumes.

The internet is now responsible for 3.7% of all global carbon emissions. And this figure is on course to double to 8% by 2025.

In order to reverse this trend - and to build a sustainable internet - Greenpixie are developing technologies and techniques which measure the carbon emissions of organisations’ digital activity.

We are also raising awareness, speaking across Europe and around the world at climate events and functions, to engage a wider audience in this overlooked aspect of the climate emergency.

Speak to us today about your digital processes and, together, we can stay at the forefront of the fight against climate change.

What is a digital carbon footprint?

What is digital carbon?

The Greenpixie carbon calculator is a great introduction to digital sustainability, offering an instant estimation of any website’s carbon footprint. Read on to discover how it works.

Our carbon calculator is the first step on your journey towards a low carbon website.

Our tool provides an estimate of the carbon emissions of your website’s homepage per view and compares it to the average, allowing you to understand your contribution to the growing issue of digital carbon.

Simply put, the calculator looks at how much data your website has to transfer and how efficiently it does this. From this we can work out its energy consumption and ultimately translate that into CO2 emissions.

Of course, there are lots of different ways to measure digital carbon and lots of different places where the line could be drawn when calculating the emissions of a single website. This is why you might notice slight differences between the results of 

 calculator and other online calculators. Our aim is to provide the fastest, most comprehensive and most accurate calculator available.

The first stage is to figure out how much data you’re transferring through your website.

To do this we have a look at what’s on your homepage — for example, are there high resolution pictures or large video files? How is the website built? And, other considerations relating to the design and functionality.

Basically, the more complicated and inefficient your homepage is, the more data you’re transferring.

After we’ve done this, we can then translate data transferred into kWh.

We can do this by estimating how much energy it takes to;

transfer the data back and forth across the internet’s vast telecoms network

and to display the result on an end user’s device

These estimations depend on knowing how much energy it takes to run these elements, for example the electricity used to run, cool, and maintain the servers which host your website.

Finally, we just need to figure out how much carbon this energy use translates to.

To do this, we use data from the National Grid to estimate how much CO2 is released per kWh of energy.

“My website is hosted by green servers, so none of this should be a problem for me

You’re partly right — if your website is hosted by renewable servers, there’s less carbon involved from your end, and so we account for this when converting your energy consumption to CO2 emissions.

However, this doesn’t solve the whole problem. We still have to consider the end-user display, which involves someone viewing your website and downloading it to their device. The transfer of the data across submarine cables and through telecommunications centres are also still a factor.

So there you go! This is how we arrive at our estimate of how much CO2 your website releases per hen you put your URL into our carbon calculator.

No. But this is a very useful tool — and we’re excited to be developing and learning all the time.

We’ve got immediate plans to factor more and more aspects of digital carbon into our calculator, while keeping it quick, free and accessible to all.

How does the Greenpixie carbon calculator work?

Optimism is mixed with reservation ahead of COP26, as the annual opportunity to get serious about the climate crisis once again lacks any mention of digital sustainability.

As we look ahead to COP26, the landmark climate conference happening in Glasgow this November, 

 on the state of climate change is throwing light on just how urgent our situation is becoming. But how does digital carbon fit into all of this?

If you’ve turned on the news recently, you might well have heard something about climate change. A new landmark report by the Intergovernmental Panel on Climate Change (IPCC) has been making headlines, and we wanted to figure out what it’s saying, and what it means for digital carbon’s place in the upcoming international climate conference.

The IPCC produces these reports about every seven years — they’re called Assessment Reports and this one is number six (or AR6, for short). They provide a synthesis of scientific understanding of climate change and carry a lot of weight in policy circles. The actual report is about 4000 pages long — there’s a lot to say! — but the IPCC have provided handy summary documents for 

The gist is this: AR6 provides us with the clearest consensus yet on climate change — it’s happening, and the cause is human activity. Some major headlines include:

Average global temperatures are up by more than 1°C since preindustrial times

Extreme weather patterns are increasing, from droughts to floods and everything in between

And, crucially, humans are causing these changes, and need to act almost immediately to divert the worst effects

This discussion that can often seem abstract has been thrown into sharp reality by news of increasing extreme weather patterns, including observations of a 

 that are sweeping Greece and other Mediterranean countries.

It’s undeniable — as the report highlights, our climate is already changing.
