Actions being undertaken to address climate change in Western Europe include: 1.) decreasing production 2.) eliminating tariffs 3.) increasing immigration 4.) reducing consumption

Actions being undertaken to address climate change in Western Europe typically include efforts to reduce greenhouse gas emissions, promote sustainability, and transition to cleaner energy sources. Based on the provided options:

1.) Decreasing production: This can be a strategy to reduce the environmental impact by lowering the overall production of goods and services, which can, in turn, reduce associated emissions.

4.) Reducing consumption: This involves encouraging individuals and industries to use fewer resources and adopt more sustainable consumption patterns, contributing to lower emissions and environmental impact.

Eliminating tariffs and increasing immigration are not directly related to actions aimed at addressing climate change. While immigration policies might influence demographic factors, they are not inherently climate change mitigation strategies.

Therefore, options 1 and 4 are more closely associated with actions to address climate change in Western Europe.
