Worldwide CO2 emissions dropped by 1.3 percent in 2009, German-based renewable energy institute IWR told Reuters last week.
The institute cited two reasons for the drop in emissions from 2008: the weak status of the global economy and increased investment in sustainable energy. Global investment in renewable energy rose from $154 billion to $161 billion from 2008, the report states.
Despite the good news, the future remains an uphill battle.
"The energy-induced CO2 output in China in 2009due to its economic growth has grown to a level now that is as high asthat of the U.S. and Russia combined," IWR director Norbert Allnoch told Reuters.
