And I thought ethanol was the "biggest greenwash ever."

I can't even believe my eyes.  I just recently wrote an article about Panama's plans for a 6.5 billion dollar clean refinery.  There are talks of the same company, EDC Corporation, which is building the refinery in Panama to also build in India.  However, this coal refinery you're talking about seems absurd!

This is exactly the same logic that claims subsidizing the purchase of hybrid cars serves environmental goals by improving overall fleet efficiency.

As with Tata Ultra Mega, the claim is ONLY justified if the subsidy requires that another emitter of equivalent scale but worse environmental performance is prematurely withdrawn from service. Otherwise you are just subsidizing yet one more increase in total emissions.

The true meaning of life is to plant trees, under whose shade you do not expect to sit.

Ted Nace wrote in the OP: World Bank policy is to invest in "abatement of climate change impacts" through "investment focus on ... supercritical coal technology, ultra supercritical [...]"

Do not be deceived by fancy-sounding terms like "supercritical." We're still talking about burning coal, just at higher temperatures and pressures that notch the efficiency of the process upward from about 36 percent to maybe 43 percent.

The potential efficiencies are higher than that:
worldcoal.org/pages/content/index.asp?PageID=421

Supercritical (SC) and ultra-supercritical (USC) power plants operate at temperatures and pressures above the critical point. This results in higher efficiencies - up to 46% for supercritical and 50% for ultra-supercritical
