Cependant, c'était le cas avant que nous ayons un trou dans la couche d'ozone, avant que nous n'ayons signé le protocole de Kyoto. C'était le cas avant que nous ne devenions un exportateur net de gaz naturel et je dirai un gros exportateur.
However, I think that was true before we had a hole in the ozone layer, before we had signed the Kyoto protocol, before we became a major exporter of natural gas, and before much of the world was turning to natural gas.
