ABSTRACT
Studies have shown that the intensification of the greenhouse effect in recent years has
caused a rise in global warming with effects on climate, therefore, may compromise the
life on the planet. This intensification is a function of the increase in concentration of
greenhouse gases from human activities. This research aims to quantify the contribution
of emissions of greenhouse gases, released by a company in the metal-mechanic, in Rio
de Janeiro - RJ, propose scenarios in which these emissions can be offset.
Quantification was achieved by using methodology developed by the IPCC. The offer
of emissions is given by replacing the fuel used in vehicles, implementation of energy
production by photovoltaic system, digestion of domestic sewage and reforestation. The
justification of the research is based on contribution to the alleviation of the intensifying
greenhouse effect, global warming and climate change, which consequently may help to
preserve life on Earth. Of the total emissions into the atmosphere by the company under
study, in 2008, was obtained a value of 422 tonnes of CO2 equivalent, with 177 tonnes
from fuel consumption by transport, 87 tonnes from the waste generated, 2,2 tonnes
from effluents generates, 8.81 tons from consumption of electricity and 148 tonnes from
domestic industrial processes. In the scenario where we contemplate the mitigation
measures, such emissions are reduced to 349 tonnes of CO2 equivalent. If employee
reforestation as the only way to neutralize the emissions of the company, it is necessary
to restore plant to an area of 1,33 hectares. This alternative may prove advantageous in
the short term it does not cause major changes in routine processes. However, if Metal
Master chooses only by reforestation and keep the emissions standard similar to the year
2008, over the years will require a vast expanse of land reforested. This fact indicates
the importance of changes in the industrial environment, to allow the circumvention of
long-term.
