We are trying to create a PR and communication campaign that the government will use to motivate the public (especially old people and people from villages) to replace their old coal stoves that emit high emissions. We want to motivate those people to replace coal stoves with more environmental-friendly technologies such as gas, electricity, geothermal energy systems, solar panels etc. We will do this by asking the people via in-depth interviews and questionnaire surveys. Do you have any experience with successfully persuading people to throw away their old coal stoves?
