emissions reduction have); and 3) even in their totality, U.S.
carbon dioxide
emissions have a negligible influence on local / regional /
global climate change (even a immediate and permanent cessation of all our
carbon dioxide
emissions would likely
result in a mitigation of
global temperature rise of less than one - quarter of a degree C by the end of the century).

carbon dioxide emitted as a
result of U.S. coal consumption.

Significant progress in reducing
emissions and limiting climate change could be achieved if companies 1) unequivocally communicate to the public, shareholders, and policymakers the climate risks
resulting from continued use of their products, and therefore the need for restrictions on greenhouse gas
emissions consistent with the 2 °C
global temperature target; 2) firmly reject contrary claims by industry trade associations and lobbying groups; and, 3) accelerate their transition to the production of low -
carbon energy.
