The 1970s brought an era of ongoing globalization and heightened awareness to environmental issues. The decade’s energy crises highlighted the world’s dependence on oil, fueling desires to explore alternative energy production. The establishment of Earth Day and the passage of the National Environmental Protection Act in the United States brought issues of environmental preservation to the public consciousness.

At this time, Louis Berger began to establish its environmental practice. The firm provided services to clients in coal mine cleanup, water quality analysis, ecosystem preservation, disaster recovery and pollution remediation. In addition to developing its environmental practice, the firm continued expanding its work around the globe with projects in Brazil, Sudan, Sweden, the Philippines, Haiti and Cote d’Ivoire.
