Note: 2005 is the base year for the emissions inventory for Bangkok. Bangkok Metropolitan Administration
fi xes a reduction target of −15 percent below 2012 BAU emission levels. Net emissions: Parks and trees
absorb 0.1 million tons CO 2 e every year. BAU = business as usual.

In each city, mitigation potential is infl uenced by roles the local government
can play to regulate or control each emissive sector, emissions, or both. Th is
varies according to the specifi c national context and administrative structures.
