Public preferences concerning the environment have shifted in the last 30 years. Although environmental matters were high in the public agenda in the 1980s and 1990s, they receded in the 2000s. There are several factors at play behind these fluctuations. First, environmental concerns tend to shift with economic conditions. When economic prospects are good, environmental concerns are more prevalent while when economic prospects are more limited they are less prevalent. For instance, the recession of 2001 and the financial crisis of 2009 were linked with sharp drops in environmental concerns.
Another factor that can explain the decline of environmental concerns relate to the regulation and mitigation of the most visible environmental issues in the 1970s and 1980s, which resulted in improvements. This particularly the case for air emission standards, such as vehicles that became less polluting and more energy efficient. Many institutions were created to regulate environmental matters for the sake of the public.
Since 2010, environmental concerns are on the rise, mostly attributed to a growing awareness about climate change and its potential impacts on human activities.
