Act leader David Seymour last week confirmed he would oppose the Government's Zero Carbon Bill.
"New Zealand's actions are not going to change the climate. We account for just 0.17 per cent of global emissions," he said.
"In fact the Prime Minister has made very clear that the Zero Carbon Bill is simply about trying to show global leadership.
"As with her Government's positions on oil and gas exploration, gun laws and social media, the Prime Minister is more concerned about a global audience than good policy-making. But the idea that the United States, China, India and other large emitters will follow our lead on climate change is naïve.
"New Zealand will not prosper if we are forced to make significantly deeper emissions cuts than our trading partners. We will simply impoverish ourselves and push economic activity to other countries."
