"In his letter to Carney, dated Feb. 28, Hohn warned that British banks were “highly likely” to suffer losses on coal financing as the cost of renewables continued to fall and regulations on air pollution and carbon emissions tighten."
If that's the case then Hohn shouldn't even need to push this agenda at all. Coal usage would go down dramatically naturally based on market competition from renewables based on his own statement. Either he doesn't believe that, or he does and there's something else going on.
