Over-reliance on tree-planting to offset carbon emissions could push food prices up 80% by 2050
Governments and businesses hoping to plant trees and restore forests in order to reach net-zero emissions must sharply limit such efforts to avoid driving up food prices in the developing world, the charity Oxfam has warned.
Planting trees has been mooted as one of the key ways of tackling the climate crisis, but the amount of land needed for such forests would be vast, and planting even a fraction of the area needed to offset global greenhouse gas emissions would encroach on the land needed for crops to feed a growing population, according to a report entitled Tightening the net: Net zero climate targets implications for land and food equity.
