The Global Carbon Budget is produced by 76 scientists from 57 research institutions in 15 countries working under the umbrella of the Global Carbon Project (GCP). The budget, now in its 13th year, provides an in-depth look at the amount of fossil fuels that nations around the world burn and where it ends up.

Global emissions of carbon dioxide from fossil fuels and industry are expected to grow slowly in 2019 due to a decline in global coal use.

The growth rate in 2019 is set to fall to 0.6 percent, down from 2.1 percent the previous year. This is due to declines in coal use in the European Union and the United States, as well as slower growth in coal use in China and India, and overall weaker global economic growth. The decline in coal use has been offset by sustained growth in oil and natural gas.

The study has an uncertainty range between -0.2 percent and +1.5 percent. A decline in global emissions in 2019 cannot be ruled out given uncertainties in the projection.

The projection comes from the 2019 Global Carbon Budget, published on Wednesday by the Global Carbon Project in the journals Nature Climate Change, Environmental Research Letters, and Earth System Science Data. The Global Carbon Project is supported by Future Earth and the World Climate Research Programme. It is the first full-year estimate of the increase in global fossil carbon dioxide (CO2) emissions in 2019.
