Rest of the world
The region Rest of the world is a residual of the countries not included in any of the other regions. This implies that it includes Africa, most Asian countries and Latin America. This region currently has greenhouse gas emissions of 16.6 Gt CO2e (in 2002). The business-as-usual scenario implies an increase to about 22.6 Gt CO2e per year in 2030.
Abatement potential
The abatement potential for the region is estimated to about 11.1 Gt in 2030. The largest potential, both in relative and absolute terms, is found in the Forestry sector. Forestation and avoided deforestation can reduce emissions with 6.5 Gt CO2e, which is more than all the estimated business-as-usual net emissions from the sector. The potential is also large in the Buildings sector (80% of business-as-usual emissions). This is followed by the Industry sector (ca 40%), Power (ca 25%) and Transport (ca 20%). In the Agriculture and waste sector the potential is estimated to around 15% of business-as-usual emissions. The theoretical potential is larger, but due to significant difficulties in terms of implementation it is not seen likely that all of the theoretical potential is achieved.
Abatement cost
The average cost varies substantially between the sectors. Within Buildings and Transport there is a significant potential of negative cost abatement opportunities. Looking only at the abatement potential at a cost below € 40/tonne CO2e, the average abatement cost in these two sectors are € -77/tonne CO2e in Buildings and
€ -23/tonne CO2e in Transport. Virtually all of the potential within these sectors come at a zero or negative cost. The other sectors have a cost of € 13/tonne CO2e in Agriculture, € 15/tonne CO2e in Power and about € 23/tonne CO2e in the Industry and Forestry sectors.
The average abatement cost across all sectors is close to
€ 13/tonne CO2e if the negative cost abatement opportunities are valued ‘at cost’. A more conservative estimate, valuing the negative cost opportunities at zero, would result in an average abatement cost of ca € 18/tonne CO2e in this region.
