After revision:  Our emission estimatesreflect near real time inventories of emissions } uncertainty). Unlike other emerging estimates, ours show the temporal dynamics of emissions based on actual emissions data from power generation , transportation, industry, international aviation and maritime sectors in 34 countries that account for >70\% of world energy-related CO2 emissions in recent years.
