The Gresham House forestry fund is suggesting that via a portfolio of existing and new forests it might generate an internal rate of return of 6 per cent a year in the long term, with the potential upside from selling carbon credits via new forests. The fund is targeting 10,000 hectares (24,700 acres) of new woodland creation, which is expected to save 1.3m tonnes of CO2 over 20 years. The minimum investment is £100,000.
“Trees are, quite simply, the most effective strategy, technology, we have to guard against heat in cities,” said Brian Stone Jr., a professor of environmental planning at the Georgia Institute of Technology.
Trees can lower air temperature in city neighborhoods 10 lifesaving degrees, scientists have found. They also reduce electricity demand for air conditioning, not only sparing money and emissions, but helping avoid potentially catastrophic power failures during heat waves.
