assessment, developed by the National Institute for Environmental Studies, Kyoto University and Mizuho Information
Research Institute. This model has already been applied to assess the mitigation target in Japan. The model applied
for the deep decarbonization pathways is a multi-region version of AIM/Enduse model of Japan, that is to say, the
model is composed of 10 regions and considers the regional differences in renewable energy potential and energy
demand characteristics. The 10 regions almost coincide with the business areas of 10 public power supply firms.

Jorge Tovilla,
Independent Consultant GHG emissions in Mexico are rising due to an increasing use of fossil
fuels. As the population slowly stabilizes (projected to be 151 million
by 2050)1 and continued economic growth is expected, it is crucial to
design a deep decarbonization strategy before new infrastructure is
built. Many actions to mitigate climate change have valuable co-benefits
(local health improvement, economic savings, and greater productivity,
among others), and some are also linked to poverty reduction and social
inclusion (for example food and energy security).
Proven reserves of oil in Mexico are estimated to be around 1,340 million
tons of oil equivalent (toe), while gas reserves represent an additional 430
million toe.2 The national energy reform approved recently is expected
to boost investments in oil and gas production. Electricity generation is
mainly produced from natural gas (50%), oil (11%), hydro (15%), and coal
(13%); energy-intensive industry accounts for 13% of GDP.
Urban population reached 72% in 2010, and it is expected to be close
to 83% by 2030. Around 98% of households have access to electricity
to date, and there are 210 vehicles per 1,000 people. In some rural
areas, wood is still used as the main fuel for heating and cooking.
