Let's see the breakdown of greenhouse gases first
Breakdown of emissions by gas in total greenhouse gas emissions of anthropogenic origin (based on carbon dioxide equivalent)
Carbon dioxide: 76.0%
Fossil fuel origin carbon dioxide: 65.0%
Carbon dioxide due to deforestation and forest fires, etc.: 11.0%
Methane: 16.0%
Nitric oxide: 6.2%
Freon: 2.0%

As you can see immediately, more than 70% of the greenhouse gases are carbon dioxide, as you can see. From here, let's look at the ratio of carbon dioxide emissions in countries around the world.
World carbon dioxide emissions in 2013 (emissions by country)
Total world emissions: Approximately 32.9 billion tons
China: 28.7%
America: 15.7%
India: 5.8%
Russia: 5.0%
Japan: 3.7%
Germany: 2.3%
Korea: 1.8%
Mexico: 1.5%
Brazil: 1.4%
United Kingdom: 1.4%
Canada: 1.3%
Indonesia: 1.2%
Australia: 1.1%
Italy: 1.0%
Others: 28.0%

Japan is the world's 3.7% emissions and at the same time the fifth largest emissions in the world. Looking at this as the emissions per capita ...
Which countries emit carbon dioxide how much? How much is it per person?
Emission per capita. Emission percentage in parentheses.
China: 7.0 tons (28.7%)
America: 16.4 t (15.7%)
India: 1.5 t (5.8%)
Russia: 11.6 t (5.0%)
Japan: 9.7 t (3.7%)
Germany: 9.2 t (2.3%)
Korea: 11.6 t (1.8%)
African countries: 1.0 t (3.4%)

Japan is ranked 4th in the world and 1st in the United States. Meanwhile,
India and African countries were about 1 t, and emissions were significantly
smaller than in developed countries. In China, emissions per capita are
smaller than those in developed countries.
Efforts by developed countries are essential to reduce emissions of carbon
dioxide emissions.
