Table 1 Country statistics.

Top 20 countries ranked according to annual plastic emission ME into the ocean, as calculated in this study. The third column contains the annual MPW generated in each country. The fourth column contains the fraction (%) of MPW reaching the ocean (calculated by dividing national ME by MPW) within a year. The fifth column contains the country averaged probability for a plastic particle to reach the ocean within a year, P(E). This sixth column contains the number of rivers accountable for national emission ME, and the last column holds the number of rivers for a country that contribute to the global 80% riverine plastic emission (emitted by 1656 rivers in total).
