One of the biggest problems that human beings face is climate change and construction industry is one of the sectors causing the greatest impact, which has led him to adopt sustainable strategies. However, these have not been effective enough to reduce CO2 emissions, since solutions are required accompanied by other alternatives. Therefore, the objective of this study is to reduce CO2 by implementing CDW strategies under the following method: 1) analysis of CO2 of the major raw materials consumed, 2) use of the materials at the construction site was determined, 3) waste streams generated at the construction site were identified and those that could be reuse were highlighted, 4) CDW recycling strategies to avoid the use of the major raw materials consumption are proposed, and 5) one of the strategies proposed is further analyzed. The results show that natural aggregates generate the greater amount of CO2 due to the consumption of fuel required for their transportation. By replacing 68% of natural aggregates by recycled aggregates, CO2 can be reduced by 53%. Finally, these results can help to promote the opening of new CDW recycling companies in Nayarit and thereby contribute to the sum of sustainability practices in housing building.
One of the biggest problems facing humanity is climate change and the construction industry is one of the sectors causing the greatest impact, therefore, design strategies accompanied by new methodologies is necessary. In this sense, this paper aims to assess sustainability for the design of organizational strategies against climate change, based on a holistic and systemic approach to sustainability development, in order to contribute the decision-making in housing building organizations. The assessment was based on: 1) climate change indicators were selected from a case study; 2) a survey based on climate change indicators was designed and applied to 21% of the total organizations under study and; 3) critical indicators were identified. The result shows that 58% of the climate change indicators are critical and give evidence of the negative outlook that housing building organizations has in in terms of sustainability. The 69% of these indicators belong to the cultural dimension, it demonstrates the lack of knowledge, customs, habits and commitment to implement sustainable strategies against climate change in this organizations. Finally, the results can contribute to designing strategies to promote sustainable building by the local government, and thus achieve more sustainable organizations that contribute to reducing their impact on climate change.

Uno de los mayores problemas actuales es el cambio climático debido a la concentración de gases de efecto invernadero (GEI) en la atmósfera, producto de las actividades humanas. El objetivo de la investigación fue diseñar estrategias frente al cambio climático desde un enfoque de sustentabilidad con el fin de contribuir a la toma de decisiones en las escuelas de Jalcocotán, para disminuir el CO2 asociado al consumo de alimentos, traslados y consumo de energía eléctrica. Para esto, se analizaron las emisiones de CO2 del consumo de alimentos, traslados y consumo de energía eléctrica, se identificó la actividad de mayor impacto y se diseñaron las estrategias. Los resultados muestran que el traslado a las escuelas contribuye con el 73% del total de emisiones de CO2, el consumo de alimentos lo hace con el 24% y el consumo de energía eléctrica con el 3%. Finalmente, se implementó un plan de reforestación y de movilidad ecológica.
