Clean energy investment ‘must be 50% higher’ to limit warming to 1.5C An extra $460bn per year needs to be invested on the low-carbon economy globally over the next 12 years to limit global warming to 1.5C, a new paper says. This is 50% higher than the additional investment needed to meet a 2C limit, the paper says. It is the first to assess the difference in investments and monetary flows between the two temperature goals of the Paris Agreement, the lead author tells Carbon Brief. The paper also finds a far faster increase in low-carbon energy and energy efficiency investment would be needed to limit warming to 1.5C. Meanwhile, coal investment would not change substantially between a 1.5C and 2C scenario, the lead author says, since a dramatic downscaling of coal investments is already required to meet the 2C goal.
