Under the Kyoto Protocol, a global governmental response to climate change, most countries have been making efforts to cut their greenhouse gas emissions. Korea government has enacted various institutional policies to encourage greenhouse gas reductions. The choice experiment method is used to evaluate Korean consumers’ valuation of Korean forest carbon offset credit. A random utility model is used to evaluate Korean consumers’ valuation of Korean forest carbon offset credit. Results suggest that although consumers value three types of carbon offset, forest carbon offset is valued more than the other way (Domestic ETS, New Renewable Energy, etc.) and the overseas ETS. The results showed that Korean consumers are willing to pay 8,676 KRW/tCO2 (about 7.46 USD/tCO2) for forest carbon offset credits in domestic forest carbon offset projects. Results suggest that although consumers value three types of carbon offset, forest carbon offset is valued more than the other way (Domestic ETS, New Renewable Energy, etc.) and the overseas ETS. The people with higher level of environmental perception’s willingness to pay a premium is much more for the forest carbon offset.
