CIB W116—Smart and Sustainable Built Environments - Test Input

1. Introduction
In this article a methodology of evaluation for local environmental sustainability to insert in the
concept of local Planning.
(Plano Director Municipal). The PDM is in Portugal the most important instrument of territory local
management. One of the biggest challenges that currently the humanity faces is the raised CO2
production and emission. It is important to develop techniques and instruments that allow the public
and private controllers to implement politics that stop this CO2 excess in the atmosphere.
The problem, face to its scale, only has resolution in the political level of legal regulation, with the
elaboration of assertive laws and easy acceptance and application. It increases that this subject in
scientific terms is widely trans-disciplinary, enclosing diverse and very distinct areas of the scientific
knowledge.
2. Political framing for the proposed methodology
In local and territorial level of planning policies it is necessary to develop urban and municipal plans
that incorporate measures and methodologies that minimize or counterbalance the emissions CO 2 .
Nowadays, although the local decision makers can be interested and worried in the issues of the CO 2
emissions, due to the lack of public pressure they do not make use of the instruments and the policies
that make it possible. Therefore, these policies are not implemented as well as.
It is considered in this proposed methodology of analysis that follows: to create differentiated levels
of municipal taxes in order for the city council to encourage planning measures that will allow for a
balance of absorption and CO 2 emissions in the county/municipality.
It is also possible to define municipal taxes, in which decision makers and citizen’s voters are
interested in implementing measures inside the municipal planning policies, who harness low one
taxes to pay.
3. Proposed methodology
The proposed methodology intends to establish an accounting of CO 2 emissions in municipal areas,
having for objective to verify if the impact of people life, with its equipment, the constant urban and
road typology in municipal areas, are superior to the capacity of the existing natural local drains
(natural CO 2 absorption).
However, as if it can infer for the accounting methodology and for the presented equations, the literal
application of this methodology to the emissions of gases of greenhouse effect in cities or urban zones
is not easily practicable.
