《2011世界經濟與社會概況：綠色技術大改造》 （The World Economic and Social Survey 2011: The Great Green Technological Transformation）5日由聯合國經濟與社會事務部（UNDESA）出版，呼籲每年至少要投入1.9兆美金以避免這場災難。
Humanity is near to breaching the sustainability of Earth, and needs a technological revolution greater and faster than the industrial revolution to avoid "a major planetary catastrophe," warns a new United Nations report.
"The World Economic and Social Survey 2011: The Great Green Technological Transformation," published today by the UN Department of Economic and Social Affairs calls for investments of at least $1.9 trillion per year to avert this catastrophe.
"It is rapidly expanding energy use, mainly driven by fossil fuels, that explains why humanity is on the verge of breaching planetary sustainability boundaries through global warming, biodiversity loss, and disturbance of the nitrogen-cycle balance and other measures of the sustainability of the Earth"s ecosystem," the report says.
"A comprehensive global energy transition is urgently needed in order to avert a major planetary catastrophe," the report warns.
In his preface to the report, Secretary-General Ban Ki-moon writes that "rather than viewing growth and sustainability as competing goals on a collision course, we must see them as complementary and mutually supportive imperatives. This becomes possible when we embrace a low-carbon, resource-efficient, pro-poor economic model."
About half of the forests that once covered the Earth are gone, groundwater resources are being depleted and contaminated, enormous reductions in biodiversity have already taken place," according to the report, and, "through increased burning of fossil fuels, the stability of the planet's climate is being threatened by global warming."
"In order for populations in developing countries to achieve a decent living standard, especially the billions who currently still live in conditions of abject poverty, and the additional 2 billion people who will have been added to the world's population by mid-century - much greater economic progress will be needed," the survey advises.
"Business as usual is not an option," said Rob Vos, the survey's lead author. "Even if we stop the global engines of growth now, resource depletion and pollution of our natural environment would continue because of existing production methods and consumption habits. Without drastic improvements in and diffusion of green technologies, we will not reverse the ongoing ecological destruction and secure a decent livelihood for all of humankind, now and in the future."
To meet both the objectives of conquering poverty and protecting the environment, the World Economic and Social Survey 2011 calls for a complete transformation of technology on which human economic activity is based.
Major investments will be needed worldwide in the developing and scaling up clean energy technologies, sustainable farming and forestry techniques, climate-proofing of infrastructure, and in waste-reduction technologies, the report advises.
This "great green technological transformation" will have to be completed in the next 30 to 40 years - twice as fast as it took to accomplish previous major technological transitions.
The survey says $1.9 trillion per year will be needed over the next 40 years for incremental investments in green technologies. At least $1.1 trillion of that will need to be made in developing countries to meet increasing food and energy demands.
The report proposes to build a global public technology-sharing regime and networks of international technology research and application centers.
To rapidly spread green technology, the report says, more multilateral intellectual property rights modalities must be used than presently allowed under the World Trade Organization.
"Technological transformation, greater in scale and achievable within a much shorter time frame than the first industrial revolution, is required," the report states. "The necessary set of new technologies must enable today's poor to attain decent living standards, while reducing emissions and waste and ending the unrestrained drawdown of the Earth's non-renewable resources."
The World Economic and Social Survey comes out annually. Last year's survey called for a major overhaul of the machinery for international finance, aid and trade.
