Emissions MT (Billion 1-CO2 eq.)
Fig. 2.4 Japan’s greenhouse gas emissions: 1990–2016 (Notes (1) Percentages
in parenthesis are changes from the base year of 2005. (2) Emissions are estimated based on annual figures from various measures. Regarding preliminary
figures for FY 2016, some annual figures from FY 2015 were used in place of
FY 2016 figures that have yet to be released. Also, some estimation methodologies are being reviewed to achieve greater accuracy in emissions estimations.
Consequently, some of the figures released in April 2018 differ from the preliminary figures in this summary. Removals by forest and other carbon sinks are
also estimated and announced along with the final figures. (3) Total GHG emissions for each fiscal year and percentage changes from previous years [such as
changes from FY 2005] do not include removals by forest and other carbon
sinks from activities under the Kyoto Protocol. (4) Author created figure, with
assistance from Mathias Shabanaj Janklila, based on data from the Ministry of

four tectonic plates. As Katsuhiko Ishibashi (2011) pointed out, fifty-four
reactors (including the six at the Fukushima Daiichi plant), or 12.2% of
the world’s commercial nuclear reactors, are situated in this small island
nation where about ten percent of the world’s seismic activity occurs.
Moreover, Japan has entered a seismically highly active phase. He observes
that the Great East Japan Earthquake has raised the probability of major
earthquakes in almost all parts of the Japanese Archipelago (Ishibashi
2011).
