Our journey to becoming a carbon positive bank

We believe our bank can have a positive impact on the world around us.

We believe our bank can have a positive impact on the world around us. And, while we’ve already made decisions that mean we are a very low emissions business, we’re now starting on our journey towards becoming a carbon positive bank.

Here, you can read more about our motivation, the steps we’ve taken and our plans for sustainability going forward.

Why carbon positive?

We’ve always tried to keep our impact on the planet in mind when it comes to our work practices — we’re app-only and branchless, operate a four-day week (reducing travel and operating emissions) and are based in an award-winning green building surrounded by a woodland managed for biodiversity.

As we grow, we want to continue to understand and further reduce the impact we’re having on the planet at both a company-wide and employee level. We recognise that we need to do more to live up to our aspirations of being the best bank we can be — and that challenge excites us.

Our commitment

We’ll be investing for the benefit of the planet by removing carbon from the atmosphere. We’ve just started this journey, but we promise to be transparent about what it means, where we are and where we’re going.

01 Measure our impact and progress

02 Reduce our emissions

03 Substitute for eco‑friendly alternatives

04 Invest in green opportunities

Our carbon report

The first step…

we needed to take was to gain an understanding about our current environmental impact. To get this insight, we undertook a carbon report to measure our outputs across the business in 2021.

We teamed up with Alectro, an emissions insight specialist, to examine every aspect of our operations, including emissions from our technology, commuting, events, remote working, suppliers and more.

Our report made use of GHG Protocol, the world’s most widely used greenhouse accounting system, to ensure the results were up to standard and covered all elements of all three ‘scopes’ of that system.

This report is the first — but certainly not the last — step in Atom taking a positive move towards being carbon positive. The report shows that while we’re only beginning to understand our impact, we’ve already made a strong start through our decisions to date. We’re proud of the results and can’t wait to make clear strides moving forward.

Our carbon report results

Below, you’ll find the results of our carbon report.

Before we dive into the findings, there are a couple of key considerations to make:

Impact of COVID and working from home in 2021 — this meant our emissions from commutes were much lower than in a typical year.

Emissions from travel are expected to rise in 2022 as our team has started going into the office more often.

Our total impact was

463 tCO₂e

A value of 1.09tCO₂e per employee (based on the average of 426 full-time employees in 2021).

Please note: tCO₂e is tonnes (t) of carbon dioxide (CO₂) equivalent (e) — the standard measuring unit for greenhouse gases.

Major contributions were:


IT Equipment


Energy used while working from home


Electricity purchased to run our facilities




Other factors

Our results in detail

Let’s break down the results of our carbon report a bit further and look at some of the categories in more detail.


187tCO2e(40.45% of the total)


Our facilities emissions mainly come from our head office at The Rivergreen Centre in Durham, which is a highly innovative office space built in 2005.

Rivergreen was a long way ahead of its time when it was conceived and built and received a BREEAM rating of “Excellent”.

Atom HQ - The Rivergreen Centre

Rivergreen features a central ‘rammed earth’ wall, which uses the material from excavating the basements to act as a temperature regulator for the whole building.

The living space and hot water systems are powered by biomass boilers and a solar hot water system, and we have no air conditioning in the building. Our grey water systems use recycled rainwater that, alongside natural and stack ventilation, reduces our dependence on mains infrastructure — and keeps down costs.

All of this sits under an extensive and very beautiful green roof in a wonderful woodland setting that we manage for biodiversity.

The Rivergreen Centre is a great example of an efficient building going beyond standard design to receive a B (39) on the Energy Performance Certificate (EPC) scale — the national average is 100.

For the majority of 2021, electricity purchased for The Rivergreen Centre came from a mixed tariff that we inherited when we took the building on. We moved to a 100% renewable tariff in November 2021, so from this point (and onwards into the future) Scope 2 market-based emissions, reflecting our supplier choice, will be zero.

We also operate an office space in London, where electricity comes from a renewable tariff, resulting in zero Scope 2 market-based emissions.

Due to COVID19, and a flexible working policy that we have subsequently adopted for the whole business, in 2021 our employees predominantly worked from home. This has been taken into consideration, and increases facilities emissions because:

Not all employees use low-carbon/renewable electricity:


of staff are on a renewable power tariff, while the rest use non-renewables or are unsure of their provider.

Employees use natural gas for heating their home, and, at the moment, home environments tend to be less optimised for daytime working and cost saving. However, the additional working from home emissions are still lower than the alternative of having all employees commute to the office full time.


207tCO2e(44.75% of total)


The largest contributor to our operations’ emissions, and largest contributor overall, was purchased technology.

The emissions from physical technology were large but anticipated.

Atom bank uses Google’s cloud infrastructure for its cloud computing needs, and, as they are one of the global leaders in sustainability, the operating emissions were completely offset by them.


The embodied emissions for our physical infrastructure, however, were not offset by Google, resulting in a 5.71% overall contribution.

We’re a generous bunch, so there were some employee gifts that were sent throughout 2021, which have an associated carbon impact. We expect the emissions for these to fall in the future as more in-person events are hosted after the pandemic.

Our in-house diet was very lean for 2021 as the office cafe was closed for most of the year. However, coffee and milk purchasing was not as sustainable as it could be (though usage in 2021 was low, this is likely to increase for 2022). We provided seasonal fruit for our team from a local greengrocer.


68tCO2e(14.8% of the total)


During 2021, travel-related emissions were low but still accounted for 15% of total emissions.

This despite the fact that for seven months of the year there was almost no travel to and from the office. We also travelled very little for business.

One finding from the report highlighted that due to the variety of locations that our team live in, there is a mixture of commuting by car, bicycle and public transport, with travel by car being the most popular method of transport to and from our office but also the most polluting.

Our supply chain

Supply chain values that are widely used are typically not the most accurate or consistent, so, instead of using these figures, we’ve decided to take more tangible action.
We intend to review our supply chain going forwards to identify any areas for improvement, then take action with the aim of making it as clean and transparent as possible.

What are the next steps?

With life getting back to normal in a post-pandemic world, Atom bank employees are increasingly returning to the office to enjoy the thriving culture and the opportunity to work collaboratively in-person.

Typical office occupancy rates are currently 30–40%, and with more people commuting and extra pressure being put on facilities, it’s likely our emissions will increase as a result.

While this has been somewhat mitigated by the introduction of a four-day working week and the continuation of our flexible working policy, we still recognise that action needs to be taken to improve beyond the findings of our carbon report.

What are we doing in the short-to-medium term?

Four day week

We’ve carried out a successful trial of a four-day week since late 2021, and will now introduce it on a permanent basis. This has many benefits, including cutting commuting and working from home emissions by 20% in a year.

Employee workshops and sustainability programmes

We will run a series of sessions providing tips and advice for sustainably working from home, enabling employees to make better informed decisions on a day to day basis.

Improving our approach to recycling and reusing tech equipment

Having run a separate food waste collection for many years we will further take steps to reduce consumable waste and to increase our recycling. This will include our tech hardware.

Clean and transparent supply chain

We will review our supply chain going forwards, then take action to make it as clean and transparent as possible.

Environmentally preferable purchasing

We will make more eco-conscious decisions when purchasing goods or services to ensure that they don’t have a negative impact on our carbon footprint.

Annual carbon footprint reports

We recognise that we need to measure and track our progress from this first report, so we will be carrying out annual reports on our business.

Making electric vehicles more accessible to our team

We plan to introduce a salary sacrifice scheme to enable the leasing of electric cars for employees. Electric bicycles are already eligible for our Cycle to Work scheme, and we will be partnering with a local firm to promote this option to employees who are within a 30 minute cycle of our HQ. More charging capacity will be installed to add to the (free) charging that we have available.

What does the long term future look like?

All of these measures help us to understand and to reduce our impact and emissions.

However, in order to first become carbon neutral, and then carbon positive, we will need to develop a long-term strategy and invest in the right areas.

We’re currently researching a number of routes to achieve these goals, and we’ll provide updates when we’re able to share something more concrete.

Additionally, as part of the carbon report process, the Atom bank team were asked to vote for their top goals that sit within the United Nations Sustainability Goals (SDGs), which they believe the company should support. This will help inform the projects Atom partners with.

Sustainable development goals

The team’s top voted goals were:

No Poverty


End poverty in all its forms everywhere

Zero Hunger


End hunger, achieve food security and improved nutrition and promote sustainable agriculture

Climate Action


Take urgent action to combat climate change and its impacts

Over the coming months we will update on the progress of our involvement in various projects as we move further forward in our sustainability goals. There are certainly exciting and challenging times ahead.
