Australia: Research by the Global Carbon Budget (GCB) forecasts that CO₂ emissions will grow by 2.7% year-on-year to a 37.1 ± 2 Gt CO₂ in 2018. This follows a rise of 1.6% to 36.2Gt after a three-year hiatus with stable global emissions. The 2018 forecast is based on preliminary data for the first 6 – 9 months indicate a renewed growth in fossil CO₂ emissions based on national emission projections for China, the US, the European Union (EU) and India and projections of gross domestic product corrected for recent changes in the carbon intensity of the economy for the rest of the world.

In 2017 the GCB estimates that cement sector constituted 4% of global fossil CO₂ emissions, a rise of 1.2% from 2016. Emissions are expected to grow by 4% in China in 2018, in part due to a 1% rise in cement production. In the EU emissions are projected to fall by 0.7% with stable cement sector emissions. In India emissions are forecast to increase by 6.3% with a 13.4% rise in cement sector emissions.

Fossil CO₂ emissions are based on energy statistics and cement production data. The research makes its estimate of emissions from the cement industry using a method adapted from a paper published by Robbie M Andrew of Norway’s CICERO Center for International Climate Research in 2017.
