Firms are implementing actions on trial to minimize their own greenhouse gases (GHG) emissions impacts. However, the great majority of those actions of Corporative Social-Environmental Responsibility (CSR) are referred only to direct emissions of the main production systems. Direct emissions are those derived of an isolate process, without considering the upstream and downstream processes emissions, which respond for the majority of emissions originated because of respective firm‟s production system existence. Because the greenhouse effect occurs globally and the GHG emissions contribute to the environmental changes independently of their origin, it must be taken into account the whole productive life cycle of products and systems, since the energy invested on resources extraction and necessary materials to the final disposal. To do so, it must be investigated all relevant steps of a product/production system life cycle, tracking all activities which emit greenhouse gases, directly or indirectly. This amount of emissions consists in the firm‟s Carbon Footprint. This research purpose is to defend the Carbon Footprint relevance and its adoption viability to be used as an Environmental Indicator on measurement/assessment of CSR. It has been realized a study case on Petrobras‟s seat unity at Natal-Brazil, assessing part of its Carbon Footprint. It has been used the software GEMIS 4.6 to do the emissions quantifying. The items measured were the direct emissions of the own unity vehicles and indirect emissions of offset paper (A4), energy and disposable plastic cups consumed. To 2009, these emissions were 3.811,94 tCO2eq. We may conclude that Carbon Footprint quantification is indispensable to the knowledge of real emissions caused by a productive process existence, must serving as basis to CSR decisions about the environmental changes reversion challenge / Contemporaneamente, se est? constatando que o tema das altera??es clim?ticas, j? integralizado como preocupa??o da realidade pol?tica e econ?mica internacional, vem tamb?m adquirindo abrang?ncia e repercuss?o nos setores industriais e empresariais. As empresas, em seu enquadramento no novo conceito de combate ? mudan?a do clima, t?m adotado algumas medidas na tentativa de minimizar os impactos das suas pr?prias emiss?es de Gases Efeito Estufa (GEE). Contudo, a grande maioria das a??es de Responsabilidade Socioambiental Empresarial (RSE) quanto a essa tem?tica referem-se apenas ?s emiss?es diretas dos principais processos produtivos empresariais. As emiss?es diretas s?o aquelas derivadas de um processo isolado, sem considerar os processos upstream e downstream, os quais respondem pela a maior parte das emiss?es derivadas da exist?ncia de uma determinada empresa. Haja vista que o efeito estufa sobrev?m de forma global, e que as emiss?es de GEE contribuem para as mudan?as clim?ticas independentemente de sua origem, deve-se levar em considera??o todo o ciclo de vida produtivo de produtos e processos, desde a energia investida na extra??o da mat?ria-prima e insumos necess?rios at? o descarte final. Para se fazer isso, deve-se esquadrinhar todos os passos relevantes ao longo do ciclo de vida de um produto/processo produtivo, rastreando todas as atividades que emitam direta ou indiretamente GEE. O somat?rio dessas consiste justamente na Pegada de Carbono da empresa. A finalidade desse estudo ? defender a relev?ncia da Pegada de Carbono e viabilidade de ado??o desta para ser usada como Indicador de Sustentabilidade na avalia??o/mensura??o da RSE. Para isso, foi realizado um estudo de caso na unidade sede da Petrobras em Natal-RN, avaliando-se parte de sua Pegada de Carbono. Para a quantifica??o das emiss?es, foi utilizado o software GEMIS 4.6. Os itens medidos foram as emiss?es diretas dos ve?culos pr?prios da unidade e emiss?es indiretas do papel offset A4, energia el?trica e copos pl?sticos descart?veis consumidos. Para o exerc?cio de 2009, mensuramos a emiss?o de 3.811,94 tCO2eq. Conclu?mos que a aferi??o da Pegada de Carbono ? imprescind?vel para conhecimento das emiss?es reais causadas pela exist?ncia de um processo produtivo, devendo servir de base para a tomada de decis?es de RSE quanto ao desafio da revers?o das mudan?as clim?ticas
