Bernard Jacobs

Bernard Jacobs


After 14 years in the marine water sector Bernard joined GCX in 2013 and initially focused on water sustainability at corporate level. It was this process that highlighted that “most” corporates, with all good intentions, do not have the know-how, ability or understanding of how to go about gathering, managing and reporting responsible data.

During his tenure at GCX, Bernard combined his formal accounting training, his IT skills and worked together with the highly skilled technical team at GCX and its associates to develop the GCX Eco-Analytics dashboard and reporting platform.
