Australiaâs Nationally Determined ContributionAustraliaâs Nationally Determined Contribution Australiaâs First Nationally Determined Contribution under the Paris Agreement, in accordance with UNFCCC decision 1/CP.21, December 2020 I. Australiaâs commitment Australia first communicated its Nationally Determined Contribution (NDC) under the Paris Agreement in 2015, committing to an ambitious economy-wide target to reduce greenhouse gas emissions by 26 to 28 per cent below 2005 levels by 2030. This target is a floor on Australiaâs ambition. Australia is aiming to overachieve on this target, and newly-released emissions projections show Australia is on track to meet and beat its 2030 target without relying on past overachievement. This communication provides an update on newly announced policies and measures, and a snapshot of progress on policies and measures outlined in the 2015 NDC communication.
