Meredith Fowlie nos cuenta un estudio de Frank Wolak y otros, en el que analiza esta cuestión en relación con las exportaciones de carbón de EEUU a China:
This research is finding that increasing domestic coal exports to China could reduce GHG emissions. The basic argument is as follows. Because China has very little natural gas-fired generation and highly inelastic demand for coal, U.S. exports of coal to China will substitute for other coal. Selling U.S. coal to China could raise coal prices in the U.S. and Europe (a major importer of U.S. coal). In both of these regions there is flexible natural gas fired capacity capable of substituting for coal in the production of electricity. This fuel switching would reduce greenhouse gas emissions. Keep an eye on this site for a full report coming soon.Como veis, el canal precio también puede funcionar al revés: la regulación americana puede subir los precios en el país y en Europa, y por tanto reducir las emisiones.
