Indifference curves as a tool for environment impact assessment

Area of Science:

• Environmental Science
• Environmental Economics

Background:

• Current environmental evaluation methods, such as the Battelle methodology, are often subjective.
• A need exists for more objective approaches to environmental impact assessment.

Purpose of the Study:

• To propose and demonstrate the use of indifference curves for a more objective environmental impact assessment.
• To integrate Willingness to Pay and Willingness to Accept concepts into environmental damage evaluation.

Main Methods:

• Defining indifference curves as a function between the development index and pollution load.
• Applying the indifference curve methodology to a case study of a power plant in a forest area.

Main Results:

• The proposed indifference curve approach offers a more objective environmental assessment methodology.
• Environmental Management Plan (EMP) costs for mitigating ecological damage are higher than those for air and water pollution alone.
• The case study demonstrates that incorporating willingness to accept is crucial alongside willingness to pay.

Conclusions:

• Indifference curves provide a quantitative and objective framework for environmental impact assessment.
• Valuing ecological damage requires considering both economic willingness to pay and societal willingness to accept.
• Integrated environmental and economic assessments are vital for sustainable development planning, especially for projects with significant ecological footprints.
