To prevent global warming, we need to reduce carbon emission in a daily life. The way to reduce the carbon emission is not special but easy and simple: Do not leave appliances on standby, use public transportation, save water, and use less electricity.

Ministry of Environment, Republic of Korea hold [Think Difficult] campaign to make people think it is easy to do those simple ways.

Start from November 2016, one invention per two weeks, we launched five different inventions total. When all of introduction films were released, we displayed the inventions for 4 weeks in the pop-up store.

After people visited the pop-up store, their reactions for the campaign and hashtags were spread out though online.
