“The benefits of strong, early action on climate change outweigh the costs.”

“Strong, deliberate, and collaborative action is urgently needed to stabilize greenhouse gas concentrations in the atmosphere.”

“The costs of inaction on climate change are far greater than the costs of action.”

“The developing world is the most vulnerable to climate change, and it has done the least to cause the problem.”

“Climate change is a result of the greatest market failure the world has ever seen.”

“We can't have poverty reduction without tackling climate change, and we can't tackle climate change without addressing poverty.”

“The problem of climate change is one of risk management, on a global scale.”

“The scientific evidence is now overwhelming: climate change is a serious global threat, and it demands an urgent global response.”

“Our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century.”

“Green growth is not a luxury, it's a necessity.”

“What we do in the next 10 or 20 years will determine the future of the world for the next 100 or 200 years.”

“Investing in a low-carbon future is the only pro-growth strategy for the long term.”

“A transition to a low-carbon economy will be a driver of growth, not a constraint.”
