There are suggestions we may have been incorrectly measuring methane emissions and the effect they have on overall warming.
Well known climate scientists Adrian Macey and Dave Frame have been looking at our climate change policy in relation to the rest of the world.
What they've found is that by using a more accurate metric to replicate what methane does to warming, we see that effects have been overstated by more than three or four times the actual damage.
When it came to introducing the new more accurate metric to climate change advisers within the Government they were either passive or dismissive of it.
Overall, they find the Climate Change Commission and the Ministry for the Environment simply got it wrong.
Director of the NZ Climate Change Research Institute at Victoria University Dave Frame joined Mike Hosking.
