Global Warming
Global Warming Can Be Contained for $263 Billion, McKinsey Says

The world can keep global warming in check if
nations ramp up spending on energy efficiency, clean power and
forestry projects to at least 200 billion euros ($263 billion) a
year by 2030, McKinsey and Co. said.

The investment is needed to ensure that global temperatures don’t
rise by more than 2 degrees Celsius (3.6 degrees Fahrenheit) since
industrialization, McKinsey said today in “Pathways to a Low-Carbon
Economy.” Beyond that threshold, nations including European Union
members say global warming will become dangerous.

Delegates from 190 nations aim to craft a treaty to fight climate
change in December in Copenhagen. Global action covering all sectors
of the economy will be needed to contain rising temperatures, New
York-based McKinsey said in the 192-page report.

“Without focused and coordinated action, it is unlikely that even
the most economically beneficial options will reach their full
potential,” Tomas Naucler, leader of the consultant group’s Climate
Change Special Initiative, said in an e-mailed statement.

Forty-seven billion tons of the 70 billion tons of greenhouse gases
projected to be emitted in 2030 could be cut if governments take
immediate action, McKinsey said. The annual cost by 2030 may be less
than 1 percent of the global economy -- or from 200 billion euros to
350 billion euros, it said.

Fourteen billion tons of greenhouse gases could be cut by making
buildings, vehicles and factory equipment more energy efficient, the
study said. Twelve billion tons could be slashed by investing in
wind, nuclear and hydropower as well as technology to pump carbon
emissions for storage underground and biofuels.

McKinsey also said a further 12 billion tons of emissions could be
removed by stopping tropical deforestation and improving
agricultural practices.
