Eileen Claussen (president of the Pew Center on Global Climate Change) and Judith Greenwald (director of innovative solutions at the Pew Center), “Handling Climate Change”, Miami Herald, 7/12/07 – “[A cap-and-trade is] more flexible for one, allowing you to link your system to other cap-and-trade systems around the world. In today’s global economy, where companies operate in multiple countries at once, this kind of system has obvious advantages. Cap-and-trade also allows the banking of emission allowances – reducing emissions early and using the saved emission allowances for later.”
