While many of the top 100 companies listed on JSE Limited already calculate their carbon footprints, this is just the tip of the iceberg. Before long, every company will need to have at least one employee tasked with calculating its carbon footprint and suggesting how to reduce it. This will probably lead to each organisation eventually having a team of carbon footprint reduction champions. Soon carbon (and water) footprinting will be implemented and actioned by all listed companies – and not just as part of an energy audit.
