As Earth’s climate continues to warm, global carbon budgets are playing an increasingly important role in informing mitigation policy responses around the world. We explain how they work and how they are used.

Research, published today in Nature Climate Change, found that emissions drops during COVID-19 could soon be undone, as unchecked economic recovery would see global emissions bounce back to pre-pandemic levels.

The Global Carbon Budget, released today, has found that global fossil CO2 emissions in 2020 are expected to decline by approximately 7% in 2020.

NewsNew research: nitrous oxide emissions 300 times more powerful than CO₂ are jeopardising Earth’s future
New research has found that nitrous oxide from agriculture and other sources is accumulating in the atmosphere so quickly it puts Earth on track for a dangerous 3℃ warming this century.

COVID-19 has affected global emissions in six economic sectors, with a significant decline in daily global emissions. Total daily emissions in early April were similar to those observed in 2006.

WebinarsScience webinar: Disentangling environmental and human drivers of carbon dioxide uptake and release on land
In this webinar, Dr Vanessa Haverd (CSIRO) provides an overview of the land carbon cycle, including the natural and human-induced sources and sinks. She also describes the role and performance of an Australian land-surface model, and presents results focusing on the contributions of carbon dioxide fertilisation versus land-use change to the net land carbon sink

Global emissions for 2019 are predicted to hit 36.8 billion tonnes of carbon dioxide (CO₂), setting yet another all-time record. This disturbing result means emissions have grown by 62% since international climate negotiations began in 1990 to address the problem.
The figures are contained in the Global Carbon Project, which today released its 14th Global Carbon Budget.

Nitrous oxide (N₂O) is the third-most-important greenhouse gas after carbon dioxide and methane. Human-driven N₂O emissions have been growing unabated for many decades, but we may have been seriously underestimating by just how much. In a paper published today in Nature Climate Change, we found global emissions are higher and growing faster than are being reported.

We’ve developed models that we have used to assess the potential of revegetation and conservation activities in Australia to remove carbon from the atmosphere. We have also produce national and global carbon budget data products and have supported Australia’s contribution to the Global Carbon Project.
