LNG is better than diesel as tanker fuel if:  1) TOTE and PSE can guarantee no LNG / methane leaks (methane is a powerful greenhouse gas), 2) they are fully insured to cover the costs of any earthquake- or terrorist-related explosions,  3) TOTE and PSE agree to pay an escalating carbon tax to fund our required transition to 100% clean energy by 2050, and  4) recognize that future for jobs is clean energy.  http://ourrenewablefuture.org/
