This article examines how two important Brazilian newspapers covered the United Nations Conference on Environment and Development (Earth Summit). Overall, 649 news items were content analyzed to determine the type of sources used, as well as the kind of issues covered. The analysis showed that government officials were the most frequently cited sources, while environmentalists and scientists were all but ignored as news sources. The analysis also indicated that economic issues were surprisingly prominent in the coverage. These results are compatible with previous studies done in several countries and indicate that environmental media are still extremely reliant on “official” vioces. The findings also highlight the fact that the range of issues covered by the environmental media largely reflects the perceived public agenda.

环保新闻

本文考察了巴西两家重要报纸如何报道联合国环境与发展会议（地球峰会）。总体而言，对 649 条新闻进行了内容分析，以确定所使用的来源类型以及所涵盖的问题类型。分析表明，政府官员是最常被引用的消息来源，而环保主义者和科学家则几乎被忽略为新闻来源。分析还表明，经济问题在报道中出人意料地突出。这些结果与之前在几个国家进行的研究一致，表明环境媒体仍然极度依赖“官方”声音。调查结果还强调了这样一个事实，即环境媒体所报道的问题范围在很大程度上反映了公众的看法。
