Green economy implies to start a massive effort to change the world. What can we do to build a green economy for the world?

President of Mexico Filipe Calderón said: "I think we need to transfer into action the creativity and innovation that we can see around the world/we need to transform, we need to change, individual action in favor of massive action through public policy."

"There is a false dilemma when we say 'either we combat climate change, or we combat poverty.' There is a clear way in which we can fight climate change, and at the same time fight extreme poverty in our country," he said.

Chinese Minister of the Environment Zhou Shengxian said: "During the '12th Five-year Plan' period, China will firmly put in place the principles of green, low carbon, sustainable, and harmonious development between man and nature."

"In the short term, developing a green economy may facilitate economic recovery and create new job opportunities. In the mid-term, it will raise resource efficiency, reduce pollution emission intensity and curb degradation trend of ecological environment. In the long-term, developing a GREEN economy will promote larger scale, higher level and more sustained development of economy and society," he said.

Jairam Ramesh, Cabinet Minister for Rural Development, said: "The green economy is a matter of livelihoods. It's not just a matter of lifestyles/unless we protect livelihoods, unless we improve the value of our traditional livelihoods, we are not going to make our economic growth inclusive."

"So we need to worry about the green economy because, number 1, it's a matter of livelihoods. Two, it's a matter of public health, three it's a matter of dealing with climate change, and four, because it has to factor in a demographic reality, in which, really, India is unique."

President of Kenya Mwai Kibaki once said: "Kenya believes that the concept of a green economy is NOT a substitute for sustainable development, but a shift to a future that places emphasis on the natural capital base and ecosystems services. Consequently my government is tapping into the abundance of renewable energy sources to secure a future of low-carbon growth."

Rosa Aguilar Rivero, Spanish Environment Minister, President UNEP, said: "We [in the UNEP Governing Council] also debated something else that is essential and fundamental the GREEN economy. We all agreed that this is the only way. The only path for eradicating poverty, for making equality a reality, for youth to have a future."

European Union Commissioner for the Environment Janez Poto?nik said: "the whole point is that the GREEN economy is not an option…it's a must."
