Port of Newcastle environment, planning and sustainability manager Jackie Spiteri said the 2019 sustainability report also outlined the port's contribution to the social, economic and environmental wellbeing of the Hunter and regional NSW.
"Minimising our environmental footprint, diversifying trade and creating a more resilient economy requires a determined, long-term effort, with cooperation between the port and its stakeholders," she said.
"There are things we can do today to make the way we operate the port more sustainable and responsible - that is our immediate focus as we pursue our long-term diversification plans.
"Every tonne of CO2 reduced or any scale of operational efficiency we achieve will contribute to better outcomes for the future and have a positive cumulative effect that leads to significant, long-lasting results."
Spiteri said the port reduced operational "Scope 2" carbon emissions from electricity consumption in 2019 from 2018 baseline emissions
It was the first port in Australia and New Zealand to be accredited under EcoPort's Ports Environmental Review System by meeting stringent environmental performance criteria.
The port is now offsetting greenhouse gas emissions for all international and domestic corporate flights, through a partnership with Greenfleet, a leading not-for-profit environmental organisation.
The initial contribution offset 208 tonnes of CO2 equivalent, generated as part of corporate flights between January 2018 and September 2019, through the planting of approximately 775 native trees to establish a biodiverse forest.
