A cost analysis of the technologies needed to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change has shown that they are both feasible and affordable.

Published in IOP Publishing’s journal Environmental Research Letters, the study has shown that the basic technology currently exists and could be assembled and implemented in a number of different forms for less than $5 billion a year. Put into context, the cost of reducing carbon dioxide emissions is currently estimated to be between 0.2 and 2.5% of GDP in the year 2030, which is equivalent to roughly $200 to $2000 billion.
