17. Conclusions
Inequality in global FF-CO2 emission is decreasing for the period
The first decreasing of inequality (for the period x) is mainly caused by increasing emission of developing countries.
For the period , decreasing of inequality is caused mainly by decreasing emission of developed countries.
Inequality in historical accumulated emission is contributed mainly by developed countries due to large emission during their industrialization process.
