Low Carbon Fuels

Part of combating greenhouse gas emissions from vehicles will come through reducing the carbon content of fuels. This could be achieved through switching to electric cars run on a grid of renewable energy, using biofuels that have lower greenhouse gas emissions than gasoline, or other technologies that have yet to mature. It also means preventing the expansion of fuels with greenhouse gas emissions higher than conventional gasoline – gas from tar sands or oil shale, or liquefied coal.

What's clear is in order to cut greenhouse gas emissions from the transportation sector, carbon emissions from fuels will have to decrease in addition to increasing the efficiency of vehicles. But for fuel emissions reductions to be meaningful, they must be measured on a well-to-wheels lifecycle emissions basis, and the must include all greenhouse gas impacts, including indirect land use change effects.

Public Citizen, Inc. and Public Citizen Foundation

 

Together, two separate corporate entities called Public Citizen, Inc. and Public Citizen Foundation, Inc., form Public Citizen. Both entities are part of the same overall organization, and this Web site refers to the two organizations collectively as Public Citizen.

Although the work of the two components overlaps, some activities are done by one component and not the other. The primary distinction is with respect to lobbying activity. Public Citizen, Inc., an IRS § 501(c)(4) entity, lobbies Congress to advance Public Citizen’s mission of protecting public health and safety, advancing government transparency, and urging corporate accountability. Public Citizen Foundation, however, is an IRS § 501(c)(3) organization. Accordingly, its ability to engage in lobbying is limited by federal law, but it may receive donations that are tax-deductible by the contributor. Public Citizen Inc. does most of the lobbying activity discussed on the Public Citizen Web site. Public Citizen Foundation performs most of the litigation and education activities discussed on the Web site.

You may make a contribution to Public Citizen, Inc., Public Citizen Foundation, or both. Contributions to both organizations are used to support our public interest work. However, each Public Citizen component will use only the funds contributed directly to it to carry out the activities it conducts as part of Public Citizen’s mission. Only gifts to the Foundation are tax-deductible. Individuals who want to join Public Citizen should make a contribution to Public Citizen, Inc., which will not be tax deductible.
