Like New Zealand, it has high agricultural emissions and a poor climate track record so far, but it has adopted much stronger targets to cut emissions by 51% between 2018 and 2030. New Zealand’s Climate Change Commission is facing its first legal hurdle, as a group of 300 climate-concerned lawyers seek judicial review of the processes it used to calculate carbon budgets in its recently released advice to government. Carbon budgets are a cornerstone of New Zealand’s climate change response under the Zero Carbon Act and lie at the heart of the commission’s advice package.
