In order to achieve the 1.5º target we require a near-total reduction in coal use for electricity generation by 2050, with reductions of approximately two-thirds by 2030.

A rapid transition away from coal is technically and economically possible, but it will require aggressive retirement of coal plants coupled with equally aggressive deployment of efficiency measures and low-carbon power sources.

The restoration of trees remains among the most effective strategies for climate change mitigation. The global potential tree coverage is mapped at 4.4 billion hectares of canopy cover which could exist under the current climate.

Excluding existing trees and agricultural and urban areas, there is room for an extra 0.9 billion hectares of canopy cover, which could store 205 giga-tonnes of carbon in areas that would naturally support woodlands and forests.

Comparisons between electric vehicles and conventional vehicles are complex. They depend on the size of the vehicles, the accuracy of the fuel-economy estimates used, how electricity emissions are calculated, what driving patterns are assumed, and even the weather in regions where the vehicles are used. There is no single estimate that applies everywhere.

To limit global warming to 1.5º with little or no overshoot, it is necessary to use carbon dioxide removal in the order of 100-1000GtCO2 over the 21st century.
This removal would compensate for residual emissions and, in most cases, achieve net negative emissions to return global warming to 1.5°C following a peak.

Human activities have already caused 1º of global warming which will keep rising no matter what we do. For limiting global warming to below 2°C CO2 emissions are projected to decline by about 25% by 2030 in most pathways (10–30% interquartile range) and reach net zero around 2070 (2065–2080 interquartile range).
