Farm groups push for separate methane and CO2 reporting in livestock emissions accounting

A coalition of 42 farming organisations from 17 countries is calling on governments to report agricultural methane separately from carbon dioxide. The groups argue that the current method, which converts all greenhouse gases into a single carbon dioxide equivalent using the GWP100 metric, obscures the different warming behaviors of short-lived methane versus long-lived CO2. They want split gas reporting so climate policy can set appropriate reduction pathways for each gas, rather than treating them as interchangeable. The NFU supports this approach, saying it would give farmers a clearer picture of their emissions and allow for better targeted mitigation measures. The coalition is not asking for methane to be ignored, but for separate accounting so that short lived biogenic methane only needs to decline gradually while long lived CO2 must reach net zero. The EU is also working on a harmonised method for measuring livestock emissions at farm level, aiming to better capture variations between production systems and management practices.

This is a big deal for carbon accounting. If methane gets separated from CO2 in national inventories, it changes how livestock emissions are valued in carbon markets and policy targets. GWP100 has always been a blunt tool for short lived gases.

The NFU is pushing for dual accounting. That would let them report CO2e for international comparisons while also showing warming based metrics. Could make livestock look less damaging in policy debates, but the science on methane's warming effect is still debated.

Split gas reporting makes sense from a climate physics perspective. Methane decays in about a decade, CO2 sticks around for centuries. But the risk is that policymakers use separate reporting to slow down action on agricultural emissions. The coalition says they still want reductions, just different pathways.

If the UK adopts dual accounting, it could affect how livestock emissions are priced in any future agricultural carbon scheme. Right now methane is lumped in with everything else. Separate reporting might mean lower implied costs for beef and dairy, which has implications for land use and offset demand.

The EU is also looking at farm level measurement methods. That could eventually feed into carbon crediting for livestock. If you can show lower methane per kg of meat or milk, you might generate credits. But the methodology needs to be solid or it will be gamed.
