Essentially, the more energy companies invest, the less tax they will pay. In 2021, Harbour Energy's investment in new ventures amounted to $50m (in 2020: $13m). Much of this was related to Harbour's UK Carbon Capture and Storage projects – V Net Zero and Acorn. Harbour Energy states that it is already on track for Net Zero by 2035. This includes Harbour's V Net Zero and Acorn projects, as well as progress on emissions reduction actions and offsetting more than 25 per cent of emissions.
