Overview
1. Assess the role of cleaner technologies in
mitigating emissions and addressing other
economic, energy security and social
development goals in APEC
no land use change emissions
2. Potential role of emissions mitigation in forestry
APEC economies
APEC economies currently account for:
61 per cent of global economic output
60 per cent of global energy consumption
58 per cent of global GHG emissions
41 per cent of global population
APEC actions are driving regional and global
economic, social and environmental outcomes.
Technology – addressing the climate
change challenge in APEC
Aim of analysis – What is the role of
advanced, cleaner technologies in APEC on:
energy consumption & fuel mix
electricity generation & fuel mix
greenhouse gas emissions
Scenario assumptions
developed plausible APEC and global technology
pathways to 2050 in a world committed to reducing
emissions
enhanced development and uptake:
more energy efficient currently available
& future technologies
advanced lower emissions technologies
APEC, global and economy-wide uptake from ~ 2010

Mitigation potential in forestry
Globally, deforestation accounts for about 18-25 per cent of
anthropogenic emissions
However, carbon sequestration in forestry can play an important role in
reducing GHG emissions through: afforestation, reforestation,
reduced deforestation and improved forest management
APEC accounts for 54 per cent of world’s total forest area
APEC has recently experienced a net increase in forest area, which is a
reversal of historical trends
Investment in forest plantations in China is driving this trend –
also United States, Viet Nam, Chile and New Zealand
Largest recent declines in forest area have occurred in Indonesia and
Mexico – agriculture, infrastructure expansion and logging

ABARE projections
ABARE’s analysis
Focus is on reducing deforestation in tropical forest
areas in APEC
trees in tropical forests hold about 50 per cent
more carbon per hectare than trees outside the
tropics
What is the impact of halving the deforestation rate
in tropical south east Asian APEC economies over
the period 2009-2050?

Key messages
Technology will play the key role in:
reducing energy consumption
decarbonising energy supply
reducing GHG emissions
addressing energy security
allowing simultaneous achievement of other economic
and social development goals
Key messages
By 2050, emissions in high income APEC economies
could be well below current levels with enhanced
technologies
Need concerted policy action in developed & developing
economies
Need portfolio of policy options and technologies
Reducing emissions from land use change will also play
an important role in reducing growth in APEC emissions
