Major cities can fight climate change and make billions: researchers

Implementing green strategies like bike lanes and better building codes could bring 94 world cities a collective $583 billion worth of benefits, while fighting climate change, according to research by a global network of cities.

C40 Cities pinpointed transport, buildings and industry as priorities to be incorporated into climate change policies. Doing so would encourage large investments and avert 223,000 premature deaths, as people live and work longer.

"This research quantifies and provides the business case for what mayors have long known to be true: taking bold climate action also improves public health," C40 executive director Mark Watts said in a statement.

"There is no longer any trade-off for cities between delivering policies that benefit the environment, drive economic growth and improve the health of citizens."

Cities are key in the fight against climate change, according to the World Bank Group's International Finance Corporation (IFC).

More than half the global population lives in cities, which consume over two-thirds of the world's energy, and account for more than 70 percent of all carbon dioxide emissions, the IFC says.

C40 researchers said cities should implement walking, cycling and mass transit policies, introduce stringent emission standards, promote zero-emissions vehicles and establish zero emission areas.

Cities should also adopt strict regulations for new buildings and retrofit older buildings to improving heating, ventilation, air conditioning, water heating and lighting systems, researchers added.

Industry and businesses should use energy efficient technologies. Emissions capturing and maintenance and monitoring are all important if climate goals are to be achieved, they said.

By focusing on green approaches to transport, buildings and industry, cities could reduce greenhouse gas emissions by 87 percent and hazardous airborne pollutants known as PM2.5 by 49 percent, according to the researchers.
