Trends

The history of fossil-fuel CO2 emissions from Japan is remarkable for the abrupt change that occurred in 1973. With postwar growth at 9.6% per year from 1950 to 1973, total emissions were virtually constant from 1974-1987. From 1987-97, emissions grew 30% reaching 319 million metric tons of carbon. Growth during this period was characterized by a return to late-1970s consumption levels for liquid petroleum products and increased contributions from coal and natural gas use. Since 1997, Japan's fossil-fuel CO2 emissions have increased slightly reaching 343 million metric tons of carbon in 2004. Japan is the world's largest importer of coal (181 million metric tons) and liquified petroleum gas (13.9 million metric tons), second largest importer of crude oil (200 million metric tons), and third largest importer of natural gas (3.2 billion terajoules), based on 2004 UN energy trade data. Japan's per capita fossil fuel CO2 emission rate for 2004 reached an all-time high of 2.69 metric tons of carbon.
