Celanese's new ethanol: Is it Green?

I've been thinking about this news on Celanese's technology in producing industrial ethanol in China using coal and wondering if this really falls under anybody's 'green' category as I saw several green-based websites announcing this plans (e.g. BiofuelDigest, Green Car Congress, GreenTechnolog, etc).

Celanese announced early November that it is building as many as two coal-to-ethanol facilities in China each with a capacity of about 400,000 tons/year as well as a smaller 40,000 ton/year natural gas-to-ethanol plant in Texas, US. Industrial ethanol could be produced either by petroleum-based processing or fermentation processing using corn or sugar.
