Alternative scenario II uses the minimum threshold growth rate and the decarbonization rate of the economy needed to meet the emissions reduction target Alternative scenario III uses the historical GDP growth rate: and the decarbonization rate is adjusted to achieve the regional mitigation target of 30% with respect to the constant scenario in which everything would remain unchanged. Decarbonizing the economy requires electricity to be produced from renewable sources and a shift towards fossil-fuel-free electric mobility. The challenge is to reconcile economic growth with changes in the pattern of energy production and consumption in order to decouple emissions from GDP growth. This can be achieved by increasing the share of renewable energy sources in areas such as transport, and enhancing efficiency in the production structure and in the functioning of cities.
