Subject: Official Information request - Trees Required for Agriculture to
be warming neutral?
 
Dear Ministry for the Environment,
 
Using the latest MAF agricultural emissions inventory numbers, how many
hectares of typical native bush would be required to offset all
agricultural emissions that contribute to warming compared to the previous
year? (Ie year on year warming)
 
For clarity, I understand this to be N2O and any net increase in year on
year Methane emissions.
 
Yours faithfully,
 
Steven Cranston

Dear Steve Cranston
Please note that our response below (sent to you on 9 July) applies in this instance.

Dear Steve Cranston

Thank you for your time and phone conversation this afternoon. We discussed the range of questions you have submitted to us recently via the FYI website.

11 June:
1. Can you please clarify if you consider stable methane emissions as contributing to climate change? The UN defines climate change as a GHG that ‘changes the atmospheric composition’. If Methane inflow is equal or less than outflow then this definition would not be met.
2. Does MfE measure inflow vs outflow methane emissions for NZ?
3. Does MfE have any research to suggest NZ agriculture is currently warming the planet once on farm trees are included?

18 June:
Using the latest MAF agricultural emissions inventory numbers, how many hectares of typical native bush would be required to offset all agricultural emissions that contribute to warming compared to the previous year? (Ie year on year warming) For clarity, I understand this to be N2O and any net increase in year on year Methane emissions.

9 July:
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.
There are a number of ways to try and calculate changes in atmospheric methane concentration. What is the official MfE way so we can all be consistent?
If we can’t settle on how inflow and outflow are to be accounted for then we can not assess if methane has been stabilised (ie Option 2) or if it is contributing to warming or not. Pretty relevant given the goal of the bill is to stop global warming.

We discussed the option of the Ministry collating and provide a full response to all your questions in the next two weeks and you agreed with this. You are also happy for us to contact you again directly to discuss your questions if we need any further clarification in order for us to provide a full and comprehensive response.

If you have any further questions etc. about this feel free to contact us at [MFE request email]

Yours sincerely
