Better might be to capture the methane and use it to supplement residential natural gas. Here in BC you have the option to convert any percentage of your residential NG usage to 'biogas' AKA methane. (You just need to pay the higher cost for the gas.) Technically it doesn't change what comes out of your pipes, but they purchase and inject into the system an aggregate amount of biogas equal to what's purchased by customers. So you're directly offsetting burning of NG by instead using the methane that would, best case, be burnt anyway. Of course there is some waste in storage and transportation and such still, but seems like a win. At least, until all the 'free' landfill methane gets used up, and people start creating methane farms.

Remember to factor in that capturing the methane and burning it is in itself a substantial good in the greenhouse gas equation. Methane is an extremely potent greenhouse gas if allowed to release in its raw form, far more so than CO2 and water vapor - the products of its combustion.
