4.4. The following figure shows a global greenhouse gas abatement curve, defined as the abatement in 2030
compared with 'business as usual', produced by McKinsey in 2015. The width of each bar indicates potential
abatement measured in gigatonnes of CO_2, while the height indicates the cost of abatement per tonne. Based on this
information, which of the following statements is correct?
Abatement cost (€ per tCO₂e)

Reduced slash-and-burn agriculture conversion-

Reduced pastureland conversion-
Grassland management-
Organic soil restoration-
Abatement potential (GtCO₂e per year)

a. Solar energy produces more abatement per euro spent than nuclear power.
b. Nuclear energy has a higher potential to abate emissions than reforestation of degraded forests.
c. Geothermal technology has a very low abatement potential and therefore should never be adopted.
d. Solar energy should be preferred to nuclear power in the abatement of greenhouse gas emissions.
