7046 (2024). Chlöe Swarbrick to the Minister of Climate Change

7046 (2024). Chlöe Swarbrick to the Minister of Climate Change: Does the Minister agree with the Climate Change Commission that, "Methane has a strong warming effect that lasts several decades, with a smaller amount of warming lingering up to hundreds of years. By contrast, carbon dioxide has a weaker warming effect on a tonne-for-tonne basis, but lasts much longer in the atmosphere – its impacts can remain over hundreds to thousands of years"?

Hon Simon Watts: Methane and Carbon dioxide are known to have different impacts, which is why New Zealand has a 'split gas' target for domestic emissions, which considers biogenic methane separately from all other greenhouse gases. This reflects the different impact that methane has compared with other greenhouse gases, such as carbon dioxide.
