The challenge

Our research revealed that 62% of customers want their bank to help them reduce their carbon footprint.

"We know that many people in the UK want to reduce their impact on the climate, but to be able to change something in a meaningful way, they need to be able to measure it.” - David Lindberg, CEO, Retail Banking at NatWest.

As banks possess customers’ personal financial data, they are well-positioned to provide real-time carbon footprints based on people’s spending.

That’s why NatWest partnered with Cogo; to empower its 8 million retail customers to measure and reduce their carbon footprint.

David Lindberg said, “Our use of Cogo’s expertise in carbon tracking in the NatWest app is a really important first step in making it easy for everyone to live and spend in a greener way – using the power of their money to influence change.”

For NatWest, simply measuring their customers’ carbon footprints was not enough, they wanted to help their customers take measurable action to reduce their emissions. So we collaborated with their team to build a user experience within Natwest's banking app, focused on behaviour change to drive impact.


The Cogo solution

Cogo enabled NatWest to be the first bank in the world to build carbon tracking directly into its mobile banking experience.

Helping customers reduce carbon emissions

Cogo uses robust market-specific data to deliver individual transaction-based carbon footprints to NatWest users. As well as increasing customers' carbon literacy, Cogo’s Personal Carbon Manager employs behavioural science techniques, such as behavioural nudges, cues, feedback and rewards to engage customers and reduce emissions.

Providing accurate carbon tracking

Cogo uses market-specific carbon modelling to provide emissions factors mapped to NatWest’s categorisation. We enhanced NatWest’s existing taxonomy through the application of our carbon model, enabling the most accurate, credible and robust carbon tracking.

Delivering real-time carbon footprints

The standardised API enables Cogo to enrich transaction data in real-time with carbon footprints, carbon savings, personalised nudges and other data to create a relevant, personalised customer experience.

Supporting with product improvement

Cogo’s data-led research and product teams advised NatWest on how to make the most of the Personal Carbon Manager, with the main focus on driving a measurable reduction in carbon emissions. And Cogo continues to evolve its products and features, putting NatWest ahead of the competition in this space.
