B+LNZ has been at the forefront of building international consensus on the need for countries to follow best scientific practice and take a split-gas approach when reporting GHG emissions.
Last updated: 20 May 2026
With our international partners, we continue to build the global coalition calling on parties to the UN Framework Convention on Climate Change (UNFCCC) to adopt a split-gas approach to greenhouse gas reporting under the Paris Agreement.
The expanding coalition reflects momentum behind growing calls for more accurate and fair climate reporting.
The original joint statement, released in October 2025, was the culmination of several years’ effort by B+LNZ in building global conversations.
What the global coalition is calling for
The signatories have a clear message for their governments and the UNFCCC: methane is different to long-lived gases and reporting metrics must recognise that.
Bundling all emissions into a single GWP100 metric hides the real story. It ignores the different warming effects of short- and long-lived gases and makes it impossible to see what countries are actually planning to emit or reduce.
GWP100, which works well for long-lived gases like carbon dioxide, is inaccurate when measuring the warming impact of short-lived gases such as methane, especially when those emissions are trending down – as is the case in New Zealand.
A split gas approach is needed to more accurately reflect the contribution of the agricultural sector to climate change.
UNFCCC guidelines are clear and allow national GHG inventories to report GHG emissions separately and set Nationally Determined Contributions (NDCs) in any form they wish. This can be done in parallel while also reporting using the standard GWP100 metric. Uruguay has already demonstrated the best scientific practice and set a split gas NDC, and other countries should follow this leadership.
