Qualitative Result
First, CO2 emissions have been numerically measured. The data on electricity, gas and water consumption in houses, companies, schools and public and government buildings are converted into numerical values that express greenhouse gas emission reduction levels. Second, a carbon mileage incentive was used to encourage more people and organizations to participate in the reduction of greenhouse gas emissions. Third, a continuous participation in energy saving has been promoted. In the past, a campaign used to be carried out to induce voluntary participation from local citizens. Now, a carbon mileage system makes it possible to keep performing energy saving activities.
Quantitative Result
As of 2009, among approximately 220,000 households, 120,000 households (almost one in every two households) have joined the carbon mileage program. According to an analysis on the achievements from the second half of last year to the first half of this year, 11,937 (for the second half of 2008) and 18,358 (for the first half of 2009) tons of greenhouse gas were reduced. The reduction is worth about KRW 15.3 billion in terms of utility charges. Regarding the achievement during the first half of 2009, 1 point (KRW 500) was given to each member for every 10kg reduction of greenhouse gas. Furthermore, a KRW 30 million reward has been granted to 20 top organizations in terms of greenhouse gas emission reduction.
