Chris Bowen, Australia's Shadow Minister for Climate Change and Energy, has challenged the Greens to pass a climate change emissions bill, but rejected their proposal to ban new fossil fuel projects. Bowen, who is Labor's candidate for the seat of McMahon, said that Labor was committed to tackling climate change, but that the Greens' proposal to ban new fossil fuel projects was "not realistic". "We are committed to reducing emissions and tackling climate change, but we cannot do it overnight," Bowen said. "We need to transition to a low-carbon economy, but we must do it in a way that is economically responsible and doesn't put jobs at risk." Bowen said that Labor's plan to reduce emissions included investing in renewable energy, introducing an emissions trading scheme, and setting a target of net zero emissions by 2050. He also said that Labor would not support the Greens' proposal to ban new fossil fuel projects, as it would put jobs at risk and could lead to higher energy prices. "We need to transition to a low-carbon economy, but we must do it in a way that is economically responsible and doesn't put jobs at risk," Bowen said. The Greens have yet to respond to Bowen's challenge, but have previously said that they are committed to tackling climate change and that they will continue to push for their proposal to ban new fossil fuel projects.
