Working Group 3

Working Group 3 (WG3) – PES Cost-effectiveness

WG3’s primary objective is to consider the cost-effectiveness of woodland creation measures to improve water quality and providing other benefits. Wrk will focus on

  • Synthesizing evidence on the economic performance of existing PES schemes in COST countries, including wider impacts (e.g employment creation and carbon sequestration);
  • Standardising economic and financial metrics;
  • Quantifying costs (including agricultural opportunity costs) of woodland creation.
  • Quantifying returns on investment, including the societal distribution of returns, and accounting for any AES/rural development program payments; and
  • Preparing marginal abatement cost curves.

STSMs will develop best practice in estimating the cost and social effectiveness of W-for-W PES, and identify topics for further study. A training school will be held.
