UNITED NATIONS—The world will need to more than double its current infrastructure stock over the next 15 years—a massive undertaking that could either contribute to or combat catastrophic climate change—according to a new report.
Two-thirds of the $90-trillion infrastructure investment needed will be in developing countries, the Global Commission on the Economy and Climate noted in the Sustainable Infrastructure Imperative Report.
“The types of infrastructure we build—coal power plants versus wind farms and solar arrays, for example, or megahighways versus public transit systems—will determine whether we stay on a high-carbon growth path or move toward a climate-smart future,” the report said.
Despite the massive price tag, the commission of global experts said much of the money could be easily accessed by ending incentives to build dirty infrastructure, from fossil fuels to urban sprawl.
The report’s authors, including economist Lord Nicholas Stern, also emphasized that investing in green infrastructure can contribute to economic growth.
“Economic growth and climate action are mutually compatible,” Stern, who is cochairman of the commission, told journalists. “We emphasized and demonstrated with solid economic evidence that we can do both.”
Additionally, the commission found that only a small additional investment is needed to ensure that the over $90 trillion worth of infrastructure, which needs to be built over the next 15 years, contributes to rather than undermines climate-change efforts.
Developed and developing countries will face different infrastructure challenges over the 21st century. Developed countries will have to replace or repair ageing infrastructure, while the majority of construction of new infrastructure will happen in low and middle-income countries.
“Developing countries, such as those in Asia and Africa, need infrastructure to improve access to basic services, drive development and meet the needs of rapidly urbanizing populations and an expanding middle class,” the report said.
“Clearly, developing countries will lead the sustainable infrastructure story of the 21st century,” said Naina Lal Kidwai, a member of the commission and former chairman of HSBC India, because of the “sheer quantity” of infrastructure to be built in developing countries.
Lal Kidwai said the good news is that developing countries can “leap frog” a lot of the problems encountered by developed countries, which built their infrastructure with older technologies and designs.
“A lot of the investment can be designed to be a lot more new age than we have seen in the past,” she said.
Developing countries may be able to use climate financing—funds committed by rich countries to help poorer countries fight climate change—to help make their infrastructure investments greener. However, the report’s authors noted that this would not be the main source of funding.
“The hundred billion dollars in climate finance is absolutely essential and it is important for catalytic investments to really shift in the right direction,” Helen Mountford, program director of the New Climate Economy told Inter Press Service.
“What we’re focusing on here, through the report of the global commission, is that question of trillions…all of those investments need to go in a direction which help support growth, which help support, social and development goals and which support climate action.”
