Fig. 5

Comparison between the net CO2 emissions from FM (living biomass, DOM and mineral soil) as estimated by the CBM and reported in the countries’ GHGIs. Each point represents one year for the period 2000–2012, as shown in Fig. 4. The dashed line is the 1:1 line. The solid line is the regression line, shown where the correlation between the CBM and GHGIs was statistically significant (P < 0.05)
