The fees are used to carry out the compensation and restoration activities through the CUSTF. This chapter reviews the CUSTF, an environmental compensation programme that has been operating in Mexico for almost a decade and has been adjusted over the years in an effort to better meet its intended objectives. This includes land-use change due to mining, energy transmission, agriculture, tourism and service infrastructure, among other activities. The programme is intended to take action specifically by restoring soils, reforesting and maintaining forest ecosystems that were deteriorated.
