Well luckily I didn't consult either China's or India's own figures, but EU's, which addresses these concerns.
> Bottom-up national emission inventories are therefore an essential component of reporting and tracking progress towards the goals of the Paris Agreement. However, national inventory reports are not yet available for all countries and years. In addition, they are dependent on individual national reporting processes and methodological choices, they can present data gaps for specific sectors and currently, except for Annex I parties, there is no obligation to include long-term series of emissions up to the most recent year.
> The European Commission’s in-house Emissions Database for Global Atmospheric Research (EDGAR)7 offers an alternative to overcome these limitations and to complement national inventories and has the advantage of producing timely emission estimates that are comparable across countries.
> EDGAR relies on several sources of international statistics for the underpinning data. Foremost among these is the International Energy Agency (IEA). To harmonise global GHG emission estimates, this booklet incorporates IEA CO2 emissions from fossil fuel combustion sources named IEA-EDGAR CO2 emission dataset (v2), which are complemented with in-house EDGAR estimates for CH4, N2O and F-gas emissions.
