Study the data table below, which shows the carbon dioxide (CO2\text{CO}_2CO2) emissions in billions of tonnes for HICs and EDCs/LIDCs between 1990 and 2040.
| Year | 1990 | 2000 | 2010 | 2020 | 2030 | 2040 |
|---|---|---|---|---|---|---|
| HICs | 11.2 | 12.8 | 13.1 | 12.5 | 11.8 | 10.5 |
| EDCs and LIDCs | 8.5 | 18.2 | 22.4 | 25.1 | 27.8 |
The carbon dioxide emissions for EDCs and LIDCs in 2000 were 12 400 000 000 tonnes. Convert this number into billions to one decimal place and complete the data table above.
