The first changes to cutting emissions and fossil fuel growth is increased transparency in both FF production and usage and the removal of Ff subsidies.
The iea / worldbank/ imf report 2011 suggested this would save governments 600 billion,cut demand growth in energy by 5% (equal to the fuel use of Japan,Korea and NZ ) or around 4.7mbd 20% of US demand.
It would in addition save around 2gt co2 future growth,level the playing field for substitutes etc.
Nigeria which decided to reduce subsidies in JAN made the changes to quickly as alternatives were not readily available forcing shocks in food production costs and civil unrest.
The fuel subsidies were significant around 25% of the govt budget,and a limiting constraint on quality govt spend.The staged removal is now in place,
The govt investigations into the subsidies however identified substantial corruption ,including payment for fuel shipments that have never even arrived .
