We’re caring for the planet by adopting a sustainable approach to managing our business, and helping our customers to do so too.

Protecting the environment

We continue to track towards our 2020 operational environmental targets. These have been set across a range of areas including our fleet, building energy use, and waste.

Eighty-nine percent of transactions are made in Internet Banking or our Mobile Banking app. With more customers using our digital products, we’re using less paper and saving more trees.
