It would have to go into the carbon budget of emissions down to 10% or less of 2000 level. Sure it is a small part of the solution, in that it changes the (25 times as powerful as CO2) methane with water vapor and CO2, both also GHGs. It also re-uses waste unless it is purposely grown bio-fuel. Using it instead of composting it is not part of the solution to the vastly depleted soils of our biosphere.
It depends on how compostable it is. Dumps are full of non-compostable garbage, toxins, and pathogens, while cow poop on farms is often partially composted and used to fertilize the agricultural soil somewhat. Fully composted is much better for soil health.
Methane from sealed dumps is used for burning for power generation, usually for a small local area. Used cooking oil is great for biodiesel, but not growing plants for ethanol or bio-diesel.
There has been a fairly recent article on the myth and carbon penalty of biofuels.
‘Biomess Award’ Given to UK’s Department of Energy and Climate Change
Biofuelwatch | April 10, 2014 10:02 am | Comments
"Campaigners have awarded the UK Department for Energy and Climate Change (DECC) the “Biomess Award” after coming out on top of an online poll coinciding with a major biomass industry conference in London, with Drax and the Green Investment Bank coming a close second and third place, respectively."
"The award for forest destruction was given at an alternative awards ceremony held last night outside a gala dinner for delegates. After a last-minute change of venue the dinner took place at the conference venue, Grange St Paul’s Hotel. More than 40 people held banners reading: “Big Biomass Fuels: Deforestation, Landgrabbing & Climate Change” and “
Big Biomass Is Greenwash not Renewable Energy”."
This quote from "How to Mitigate AGW"----
"
the US government is largely captured by the very corporations that are causing the climate disruption"
The corrupt corporate/gov't alliance..............short term thinking to the point of irreversible methane turnover.
