Although farm animals aren't included in New Zealand's Emissions Trading Scheme (no country has put agriculture in to any sort of GHG scheme), many people still point fingers at 'polluters' and regard the animals and their owners as free-loaders.The rest of Rowarth's article explains why this is "odd". Basically: farmers are the backbone of the economy, NZ's emissions are globally small, and there's really nothing farmers can do anyway.
Whatever our contribution to the nation's economic spine, we farmers are actually free-loaders in respect of emissions. We emit like mad and the taxpayer picks up the tab. This is the undeniable truth - regular payments are being made by the NZ government for our agricultural emissions.
Yet the chief EPA scientist supplied an opinion piece to the Rural News, on the topic of agricultural GHG emissions, that doesn't just avoid admitting the public subsidy of agricultural emissions, but is entirely framed as a counter-argument to the 'odd' people who are rude enough to mention it in public.
The EPA administers New Zealand's ETS. The EPA said they hired Rowarth to help "New Zealanders understand the science behind EPA decisions". That's a fine role, but it does not include spouting bollocks about ETS policy in the rural press.
Call me old-fashioned, but this seems like a no-no to me. Suppose for example that Electricity Authority hired Lew Evans or Geoff Bertram as its chief economist and let them keep spouting their views in the mainstream media. Or suppose that FSANZ hired Katherine Rich or Sue Kedgely on similar terms regarding food policy. Or suppose the police hired Garth McVicar or Dakta Green as a drugs policy advisor without constraints on how that role was parlayed in the news media.
I reckon that regulators should not be public advocates for or against the laws they enforce.
Update 5 Jan
Based on FB discussion I think the above post goes a bit too far, because it doesn't mention the fact that regulators should actually promote the things they're legally charged with promoting and we should applaud regulators when they do this.
I don't think this saves Dr Rowarth however. The objective of the EPA is "to undertake its functions in a way that contributes to the efficient, effective and transparent management of New Zealand's environment and natural and physical resources".
We might disagree about whether Dr Rowarth's column was contributing to the "efficient and effective" part of this objective, and I would argue it wasn't, but there was definitely no "transparent" contribution. On the contrary, the article opened with a deliberate attempt to obscure the fact that cleaners and truck drivers pay for farmers' emissions through their taxes.
