Methane has a short half-life in the atmosphere, so its cumulative effect after a few decades is close to CO2 unless you're constantly outputting more, and that's assuming you're not burning it. In the case where you're making methane from atmospheric CO2 and then burning it, it's just returning the same CO2 back, which per the article is carbon neutral. |

The issue with burning is that methane can leak during transport.
