The OECD countries have had 16% economic growth with a greenhouse gas emissions reduction of 6%, over 10 years.

Keep in mind that economic growth, as such, does not necessarily make the economy better for people in general. That result occurs only when the growth is distributed so as to reduce poverty and suffering, which may or may not be the case. Since 2008, that has generally not been the case. This is a separate issue, and doesn't invalidate the article's point, but we should not say "Growth, hooray!"
