The government would only publicize the emissions that benefit us politically, which are likely the primary polluters we already know about (China, India, etc).
I’m not sure what those figures are for. They list India with 126.5 million kg of plastic “dumped”, yet the Phillipines is #1 with nearly 3x that amount of plastic waste going down its rivers into to oceans: 360 million kg (3.6 × 10^5 Metric tonnes) of plastic waste according to https://www.science.org/doi/10.1126/sciadv.aaz5803
Corporations are multinational. The atmosphere doesn't care if that methane plume came from a plant in the US or a US-owned plant in Nigeria. Or on an rig in the North Sea.
