Los estudiantes universitarios tienen cada vez más acceso a la información ambiental, pero eso no significa que haga el desarrollo de un comportamiento compatible. Con una escala aplicada en 1035 estudiantes universitarios de Brasil y Portugal, se examinó cómo está estructurado el comportamiento ambiental de estos estudiantes. Con el uso de técnicas estadísticas multivariantes, fue verificada una similitud en el comportamiento ambiental de los dos grupos, con las creencias ambientales si manifestando por una oposición a la visión antropocéntrica. Las actitudes ambientales tienen como antecedentes las preocupaciones relacionadas con el medio ambiente. Estas preocupaciones influyen en la opción para el control del crecimiento económico, reforzada por una tendencia ecocéntrica y se caracteriza por una perspectiva de disminución de la producción y del consumo además de la promoción del bienestar. También sí verificó que la opción por el consumo verde no se realiza plenamente, aunque se verifica una tendencia favorable.

Palabras clave:
Actitudes ambientales; Comportamiento ambiental; Consumo verde; Estudio transcultural

Assertive Dimensions We are approaching the maximum number of people that Earth can support. Beliefs The balance of nature is very delicate and can easily be disturbed. Human beings have the right to modify the natural environment to fit their needs. Humanity was created to rule the rest of nature. Humanity does not need to adapt to the natural environment because it can modify it to fit its needs. In order to keep a healthy environment, we have to control the economic growth. The reduction of global warming should be a priority to all countries. Global Concerns Deforestation of large forests can compromise the future of humanity. Pollution of rivers and lakes can affect the quality of human beings' life. Air pollution in my town is something that worries me a lot. Local Concerns The disposal of urban waste should receive continued attention from public managers. Urban growth is increasingly harmful to the environment. I 'm favorable to an international tax for the countries that generate more greenhouse gases. Global Attitude Some countries should limit their economic growth to avoid the abusive usage of natural resources. The pollution of the oceans should deserve priority attention from all countries. I must save electricity in my house to contribute to the improvement of the environment Local Attitude I must use public transportation to help the environment. I have to save water at home to take care of the environment. How ease the disposal or recycling are should always be considered when buying a product. Potential Consumption The durability of a product reduces its environmental impact, even if it is more expensive A certification indicating that a product was made following environmental standards helps my purchase decision. Companies should be encouraged to use recycled raw material as a way to reduce their environmental impacts. When I buy, I prioritize products that are more easily recycled. Actual Consumption Choosing a product, I prioritize the environmental aspects rather than the price/quality. Between two similar products, I prefer the one produced with recycled raw materials. I purchase products that do not waste resources in their packaging. Note: Responders could indicate their level of agreement in a scale from 1 to 4, 1 meaning "totally agree" and 4 "totally disagree".
