The article talks about how important it is for climate policies to reduce greenhouse gas emissions worldwide using cleaner energy technologies and efficient energy use. The researchers compared the climate policies in Australia and the Asia-Pacific Partnership on Clean Development and Climate to see if they are effective. They found that these policies focus too much on specific technologies and don't include widespread pricing on emissions to be most effective. Also, they rely too heavily on voluntary efforts and don't give enough support for low-emission technologies. In short, the study suggests that for climate policies to work well, they need to have broad emissions pricing and strong support for clean technologies.
