Randomized trial analyzes economic and environmental benefits of green investments in airports, indicating significant impacts.

Key Points

  • This research aims to evaluate the economic and environmental impacts of green investments in major airports in Türkiye from 2015 to 2024.

  • Utilized input-output and difference-in-differences analysis methods to assess impacts on economic growth and environmental performance.
  • Examined the effectiveness of sustainable aviation policies and the impact of a fossil fuel tax compared to a fuel subsidy.
  • Green investments generated a GDP contribution of 1.45 to 1.60 units per unit of investment and had positive employment impacts in job years.
  • Carbon efficiency improved with reductions of 214 to 233 tons of CO2 per million USD invested, especially at Istanbul Airport.
