What can we do to hit the 1.5C limit?
Routes to 1.5C
The IPCC maps out four pathways to achieve 1.5C. Reforestation is essential to all of them, as are shifts to electric transport systems and greater adoption of carbon capture technology.
Carbon pollution would have to be cut by 45% by 2030 – compared with a 20% cut under the 2C pathway – and come down to zero by 2050, compared with 2075 for 2C. This would require carbon prices that are three to four times higher than for a 2C target. But the costs of doing nothing would be far higher.
