Transport makes up nearly 10% of all greenhouse gas emissions across the Indo-Pacific. But that percentage is very different for countries across the region.

The data for this graphic comes from Climate Trace, which independently tracks greenhouse gas emissions globally.
The graphic depicts how a country’s transport-related emissions compare to its overall greenhouse gas emissions, and how transport-related emissions break down into domestic and international aviation and shipping, as well as road and rail transport. You can see these in gross terms or in “per capita” terms (emissions per person), which allows for comparisons between larger and smaller countries.
The emissions are measured in units of tonnes of CO2 equivalent. The “equivalent” part is designed to account for other greenhouse gases by comparing the effect they would have on the climate over 100 years to that of carbon dioxide.
Note: In the pie chart, “mt” means millitonnes, or kilograms, not megatonnes (1 million tonnes).
