A strategy to reduce greenhouse gas emissions from international shipping is being welcomed in New Zealand.
Climate Change Minister James Shaw and Associate Transport Minister Julie Anne Genter say the successful adoption of a maritime greenhouse gas emissions reduction strategy at the United Nations International Maritime Organisation (IMO) is an important breakthrough.
The IMO on Friday agreed a strategy to reduce international shipping emissions by 50 percent by 2050, compared to 2008 levels, and urgently phase out emissions from shipping this century.
"There is now clear agreement that international shipping must urgently act to reduce emissions," Mr Shaw said.
He said the transport sector had an important role to play in the global climate change effort.
"The IMO strategy is another significant example of what can be achieved when governments step up and countries work together," Ms Genter said.
Associated Press reported environmental activists say that while shipping contributes only 2 to 3 percent of global greenhouse gases, the industry's efforts are essential to combating climate change.
European Union members and other countries wanted a 70 percent to 100 percent reduction in greenhouse emissions by 2050.
