Accounting for global greenhouse gas emissions

Global Carbon Budget

Carbon dioxide is the most significant greenhouse gas contributing to human-induced global warming. The Global Carbon Budget provides detailed information about the sources and sinks of carbon dioxide worldwide. CSIRO works with many international partners to develop the budget annually as part of the Global Carbon Project.

Global Methane Budget

Global emissions of methane, a greenhouse gas more potent than carbon dioxide, are rising at an accelerating rate. The Global Carbon Project’s global methane budget details the sources and sinks of this important greenhouse gas. CSIRO works with many international partners to develop the budget every second year.

Global nitrous oxide budget

Nitrous oxide in the atmosphere contributes to global warming as well as depleting the ozone layer. The Global Carbon Project’s Global Nitrous Oxide Budget presents an inventory of the natural and human-induced sources and sinks of nitrous oxide. The budget is developed by an international team of research organisations, which includes CSIRO.

Australian carbon budget

The Australian Carbon Budget assesses Australia’s natural and human-induced carbon fluxes for the period 2010 to 2019. Our work shows that from 2010 to 2019, human-induced carbon emissions have far exceeded the capacity of natural sinks to absorb them.

Emissions reductions solutions for Australia's hard-to-abate sectors

FutureFeed livestock feed

A livestock seaweed feed supplement could help global food security and fight climate change by reducing powerful greenhouse gas emissions.

Sustainable aviation fuel

With the rest of the world transitioning to low carbon liquid fuels to meet their own net zero goals, how can Australia develop its own successful low carbon liquid fuels industry?

Green metal production

A new sustainable process for metal production that reduces the need for fossil fuels and slashes carbon dioxide emissions.

Carbon capture and storage (CCS)

Carbon dioxide storage

Improving carbon storage technologies to allow CCS to be a viable option for Australia's future

Offshore CCS monitoring

We are collaborating on a series of projects that will see the development of methods and guidelines for offshore carbon capture and storage (CCS) monitoring, using world-class research technologies.

Carbon capture and utilisation (CCU)

CSIRO FUTURES

CO2 Utilisation Roadmap

CCU provides the opportunity for Australia to capture CO2 from emissions or the atmosphere and convert it into valuable lower or zero emissions products. Our CO2 Utilisation Roadmap explores how Australia can scale-up its use of CCU.

Direct air capture (DAC)

We're working to develop low-cost, energy-efficient DAC technologies that can be used to capture carbon dioxide at point source emissions (CCS or CCU) or directly from the atmosphere (CDR).

CarbonAssist

An inexpensive unit for capturing carbon dioxide that is agile and readily deployable for different applications in heavy industries, food and beverage production, chemical manufacture, medical and construction.

Removing carbon dioxide from ambient air

We are developing a technology to capture carbon dioxide directly from ambient air.

Carbon dioxide removal (CDR)

Getting to net zero and beyond

We’re leading a national effort to develop carbon dioxide removal technologies that are fast, scalable, responsible, as well as cost-effective and permanent systems for capturing and storing carbon.
