New Zealand is consistently sucking up carbon, Australia less so

Embargoed until: Publicly released:

Researchers have measured the Australasia region’s carbon emissions and storage over the last decade, finding that the Tasman Sea neighbours together nearly achieve net zero. New Zealand’s forests suck up carbon dioxide, and the country has lower reliance on fossil fuel emissions for energy, meaning Aotearoa is a consistent carbon sink. Australia jumps back and forth between a carbon sink and a carbon source, due to extreme weather events, wildfires, and a high reliance on fossil fuels for energy and exports. The authors note that this research did not look at methane, a potent greenhouse gas produced by both countries.
