Regional Greenhouse Gas Initiative (RGGI) in the Northeast U.S.
(RGGI. 2007). the Western Climate Initiative (WCI) in the Western
u.s. (Capoor and Ambrosi. 2008) and the Climate Action Registry
(CAR. 2010). However. due to different regulatory frameworks
being developed in each region and state. there is a need to develop
national standards to help develop the registration and trading of carbon
offset projects (Sampson. 2004). Ruddell et al. (2007) further
suggested that in the absence of such national standards, forestry offset
projects will continue to be limited and inconsistent.
