Evaluation of the efficient and sustainable source utilization index for G7 countries

Öz

This study analyzes the performance of G7 countries on efficient and sustainable resource use between 2010 and 2023 using time series analysis. The study uses data sets published by the Green Growth Institute and evaluates the Effective and Sustainable Resource Use Index based on four main components covering energy, water and material and land use. In the light of the data obtained, it is observed that the overall index scores of G7 countries have exhibited a steady upward trend over the years. After 2015, there has been a significant acceleration in the rate of increase in the index, and this is associated with the effects of the Paris Climate Agreement. A country-by-country analysis reveals that Canada stands out with its investments in renewable energy, Germany has taken successful steps to increase resource efficiency in industry, and France has displayed a stable performance thanks to its low-carbon emission energy strategies. Moreover, countries such as the United States, Japan and the United Kingdom continue their efforts to increase resource utilization efficiency in different sectors. The findings of the study reveal that G7 countries are improving their resource management practices in line with sustainable development goals, but there are differences in the pace of development across countries. In this context, it is concluded that policies for sustainable resource utilization should be designed in a flexible and innovative manner according to the unique conditions of countries.
