Environmental Sustainability Index
In order to understand why the Environmental Sustainability Index is important, we must first explore exactly what the Environmental Sustainability Index is. The Environmental Sustainability Index is also known as ESI. It is a measure of the overall progress towards environmental sustainability. Its purpose is to provide consistency in grading the progress of different nations’ efforts to achieve environmental sustainability relative to the paths of other nations. The ESI was published from1999 to 2005 by Yale University’s Center for Environmental Law and Policy. Other contributors include Columbia University’s Center for International Earth Science Information Network (CIESIN), and World Economic Forum. Before the development of ESI, there was no index like it.
The Environmental Sustainability Index (ESI) was a composite index that tracked 21 elements of environmental sustainability, including natural resource endowments, environmental management efforts, pollution levels and a society’s capacity to improve its environmental performance over time. The ESI tracks a diverse set of environmental, socioeconomic, and institutional indicators that characterize environmental sustainability at the national level. ESI tracks environmental sustainability for over 122 countries. A high (ESI) rank indicates that a country has achieved a high level of environmental sustainability. A low (ESI) rank shows that a country is facing problems achieving environmental sustainability. The ESI consist of five components, including global stewardship, environmental stresses and risks, environmental systems, social institutional capacity and human vulnerability to environmental impacts.
The Importance of the Environmental Sustainability Index
The Environmental Sustainability Index allows national comparisons of environmental progress in an efficient, systematic and quantitative way. It is the first step towards a more analytical approach to decision making concerning the environment. The ESI is important, because it gives details about a countries ability to be environmentally sustainable. The ESI shows when national environmental results are below or above expectations. It shows areas that are successful or failing. ESI also investigates interactions between environmental and economic performance. It identifies best practices. The Environmental Sustainability Index is also important, because it shows areas of weakness, and areas of needed improvement. One of the most important indicators that ESI can show is the different types of environmental threats. ESI indicates the potential value of improvements regarding environmental sustainability. Environmental sustainability had been an important goal since the Earth Summit in 1992.
In order for ESI to be useful, it must be transparent, systematic and reproducible. It must be applicable to a range of conditions and situations. The Environmental sustainability index will help improve environmental policies across the globe. Nations can use the ESI to focus on their strengths and weakness to increase environmental sustainability.
