CDF Walker is an annual event that challenges participants to take at least 10,000 steps a day for an entire month. It is designed to act as a gateway for employees to embrace a healthier and more environmentally sustainable lifestyle, starting with the simple yet effective choice of walking.

The first CDF Walker challenge took place in 2022, which saw 1,735 employees take a total of over 670 million steps, effectively saving 96,000 kilograms of carbon emissions.
