Calculating Methane

Steven Cranston made this Official Information request to Ministry for the Environment

The request was partially successful.

From: Steven Cranston

Dear Ministry for the Environment,

Thank you for clarifying my recent point.
1. MfE defines climate change as a change of atmospheric concentration of a GHG.

Given that the Carbon Zero Bill references stopping climate change as it’s purpose, what is the methodology MfE is using to assess if the atmospheric methane concentration from NZ agriculture is changing?

No clear methodology has yet been made publicly available to show how inflow and outflow of methane is being accounted for. Without this information it is impossible to account for any warming impacts from methane.


Yours faithfully,

Steven Cranston
