Together, they led the campaign to pass a 2006 state law to reduce California's greenhouse gas emissions.
greenhouse gas emissions from personal transportation are significant.
The use of policy instruments like tax and subsidy to achieve public goals, such as reduction of greenhouse gas emissions?
Nevertheless, commensurate reductions in greenhouse gas emissions have not been made.
Instead, a tax on greenhouse gas emissions (“carbon tax”) would be imposed.
And any improvement is welcome—U.S. highway vehicles now let off more the 1.5 billion tons of greenhouse gas emissions annually.
For example, in British Columbia, greenhouse gas emissions might go up, while in Saskatchewan, they would plummet.
|greenhouse gas |
Any of the atmospheric gases that contribute to the greenhouse effect by absorbing infrared radiation produced by solar warming of the Earth's surface. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (NO2), and water vapor. Although greenhouse gases occur naturally in the atmosphere, the elevated levels especially of carbon dioxide and methane that have been observed in recent decades are directly related, at least in part, to human activities such as the burning of fossil fuels and the deforestation of tropical forests.
