estimation of emission reductions indicated, for two hypothetical
scenarios of CDM implementation within the state of São Paulo,
reductions of 182.5 and 19.9 kt of CO
2
. The first value refers to the
alternative involving the two municipalities of greater production
of ash and cement and the second refers to the more disadvanta-
geous alternative, with municipalities of greater transport distance
among themselves.
The use of ash as cement additive has met all the prerequisites of
the UNFCCC for CDM projects implementation and gains in certi-
fied emissions reductions, being able to generate not only techno-
logical, but also financial and environmental benefits.
