Green Economy and China’s
Development Transition (Plan C)

Three points and messages
Why: How big will the impact of China’s development be in
next decades and particularly in next 10 years ?China’s
green transition is a must.
What: What is the meaning of China’s green transition?
China should decouple its development from resource use
and environmental impact in terms of Plan C.
How: What are ways for China to go towards green
development? China has some key decoupling potentials
in three fields such as new-type urbanization, new-type
industrialization and new-type consumerism.

Environment Impact of Economic Growth
• I=Impact: Resource
consumption and pollution
impact
• P=Population:How many
people will we have ?
• A=Affluence:What’s the
consumption level?
• T=Technology and
Management: How fast
and big do we consume ?
1.1 Population: How many people China will have
• China has about 1.26 billion people in 2000 and
1.34 in 2010
• Increasing about 8-10 million persons per year
• 1.4 billion till 2020 in China (1.1 times of the year
2000)
• 10 million persons for urbanization per year
• About 60% urbanization rate till 2020 in China
2030:the peak year for China’s
population (UN)
1.2 Affluence: Growth in terms of GDP per capita
• Beginning of Reform and Opening: $250 per person (A
year growth rate is about 9-10% since then)
• 1981-1990: $500 per capita in 1990
• 1991-2000: $800 per capita in 2000
• 2001-2010: $4000 per capita in 2010
• 2011-2020: $8000 per person in 2020 (about 10 times of
the year 2000)
• 2021-2050: above $20000 per person in 2050 (about 25
times of the year 2000)

Key issues for China’s Plan C
• Model:Smart growth instead of degrowth ( towards growth within the limit of
natural capitals)
• Innovation: technology innovation with
social innovation (to strengthen a socialtechnology integrated policy system
• Capacity building: top-down initiative and
bottom-up involvement (from government
initiatives to collaboration governance)

Types of futures studies
Futures studies consider one or more of the three P’s:
1. Possible futures. What may happen?
2. Probable futures. What is most likely to happen?
3. Preferable futures. What we would prefer to happen?
• backcasting concerns the latter – identifying preferable
futures
“The major distinguishing characteristic of backcasting analysis is
a concern, not with what futures are likely to happen, but with how
desirable futures can be attained. It is thus explicitly normative,
involving working backwards from a particular desirable future
end-point to the present in order to determine the physical
feasibility of that future and what policy measures would be
required to reach that point.” (Robinson, 1990)
