Exclusive: In the first legal challenge to the plan, top climate lawyers claim the government relies too heavily on forestry and failed to consult the public

Hundreds of top environment lawyers are suing the New Zealand government over what they say is its “dangerously inadequate” plan to reduce emissions to net zero by 2050.

It is the first time the country’s emissions reduction plan has faced litigation, and the lawyers believe it is the first case globally that challenges the use of forestry to offset emissions.

Lawyers for Climate Action NZ and the Environmental Law Initiative – two groups representing more than 300 lawyers – filed judicial review proceedings against the government in Wellington’s high court on Tuesday.

The groups have provided the Guardian with first access to the claim, which argues the government has abandoned dozens of tools to tackle emissions, failed to adequately consult the public, and too heavily relies on high-risk carbon capture strategies such as forestry.
