Prime ministers Sanna Marin, of Finland, and Aotearoa’s Jacinda Ardern yesterday issued a joint statement stressing the need for “rapid, deep cuts in greenhouse gas emissions” and the importance of pursuing efforts to limit global warming to 1.5°C.

The joint communique comes just one week after the High Court found that New Zealand’s commitment to a 1.5 degree pathway under the Zero Carbon Act was “aspirational” rather than “obligatory.”
