Companies and governments do not want to flare gas. That's money just disappearing. To use this gas, however, you need to have the infrastructure set up to take the gas - you need fertilizer plants, power plants, etc that can use the gas as power. In the Middle East, these are not always possible in remote areas, so they flare it.

Natural gas is green energy because it's reducing dirty coal power plants. LNG terminals have nothing to do with fracking. LNG terminals are just an export facility.
