Although not specifically devoted to transport, several of the existing climate funds can be used for the mitigation of GHG emissions or to reduce the negative effect of impacts activities in the transport sector. These include, for example, the Global Environment Facilities, the Clean Technology Fund, the Global Climate Change Alliance, the Inter-American Development Bank (IDB) Sustainable Environmental Climate Change Initiative, the ADB Climate Change Fund, and the ADB Clean Energy Fund. Many of the funds include a sunset clause that stipulates the necessary steps that will be taken to conclude operations once a new UNFCCC financial architecture takes effect (see box 6.2). It is, however, far from clear what the future funding landscape will look like in the post-2012 regime.
