Among the non-conventional materials used in the construction sector, bamboo has potential for application due to its mechanical properties, fast growth, low cost, great availability and CO2 sequestration and storage capacity. Thus, this work aimed to evaluate the potential of climate change impact reduction with the use of bamboo culms applied in housing. The Dynamic Life Cycle Assessment (DLCA) methodology was employed. The functional unit chosen was: "1 meter of Phyllostachys pubescens culm with minimum compressive strength of 46 MPa and a service life of two years". Greenhouse gas emissions were quantified at the following stages: plantation, cut of the culm, treatment and its transportation to different locations in the country. Three different end-of-life scenarios were considered: (1) recycling, (2) landfilling and (3) incineration. The production data of the culms were associated with the number of the future Brazilian housing deficit, adopting the application of culms as scaffold for the construction of dwellings. In the end, it was possible to map which Brazilian regions are the most suitable for the use of these bamboo culms. The use of culms as scaffold to overcome the Brazilian housing deficit between 2020 and 2040 can result in -0.10 MtCO2-eq (Recycling) to +0.08 MtCO2eq (Incineration). For negative emission scenarios, the use of bamboo culms can be seen as a strategy of climate compensation, thus an important reason for the incentive of bamboo in the construction sector.
