Report: Top 50 polluters emit 75% of greenhouse gases

|By:, SA News Editor

Fifty of the world's 500 largest publicly traded companies are responsible for nearly three quarters of the group’s greenhouse gas emissions, according to a new report by a group that compiles data on climate change.

The big emitters are not doing enough to reduce emissions, and the top 50 have increased their emissions since 2009, the report says.

U.S. companies in the top 50 include oil majors such as Exxon (XOM), Chevron (CVX) and ConocoPhillips (COP), and other giants such as Wal-Mart (WMT), FedEx (FDX), Dow Chemical (DOW), AT&T (T) and Duke Energy (DUK).

Exxon, Shell (RDS.A, RDS.B), Sasol (SSL), BP and Petrobras (PBR) are the five biggest emitters in the energy sector.
