LOS ANGELES — A ballot initiative to suspend a milestone California law curbing greenhouse gas emissions is drawing a wave of contributions from out-of-state oil companies, raising concerns among conservationists as it emerges as a test of public support for potentially costly environmental measures during tough economic times.
Charles and David Koch, the billionaires from Kansas who have played a prominent role in financing the Tea Party movement, donated $1 million to the campaign to suspend the Global Warming Solutions Act, which was passed four years ago, and signaled that they were prepared to invest more in the cause. With their contribution, proponents of the proposition have raised $8.2 million, with $7.9 million coming from energy companies, most of them out of state.
