Even though Indonesia's CO 2 emissions are dominated by deforestation while China's are dominated by industry, Indonesia has much to learn from China's industrial energy saving programs. To begin with, it is only a matter of time before Indonesia's emissions from fossil fuels overtake those from deforestation. Given the long technological lock-in effects of energy systems and industries, Indonesia needs to think now about how it will tackle this problem. There are other reasons for believing that Indonesia might learn something from China -the CO 2 intensities of GDP, of industry and of cement production have been rising in Indonesia, while they are falling in China. China's better intensity performance is due to policies that Indonesia would do well to follow -adopting a technological catch-up industrial development strategy; raising energy prices to scarcity values; liberalising domestic markets and opening the economy to trade and investment; and mounting a massive energy saving program.
