KARUIZAWA, Japan (Reuters) - Group of 20 environment ministers agreed on Sunday to adopt a new implementation framework for actions to tackle the issue of marine plastic waste on a global scale, the Japanese government said after hosting the two-day ministerial meeting.

Environment and energy ministers of the Group of 20 major economies met this weekend in Karuizawa, northwest of Tokyo, ahead of the G20 summit in Osaka, western Japan, on June 28-29.

One of the top issues was ocean plastic waste as images of plastic debris-strewn beaches and dead animals with stomachs full of plastic have sparked outrage, with many countries banning plastic bags outright.

Japanese Prime Minister Shinzo Abe has said he wants his country to lead the world in reducing marine plastic trash, including developing biodegradables and other innovations.

The new framework is aimed at facilitating further concrete action on marine waste, though on a voluntary basis, after the G20 Hamburg Summit in Germany adopted the “G20 action plan on marine litter” in 2017.

Under the new framework, G20 members will promote a comprehensive life-cycle approach to prevent and reduce plastic litter discharge to the oceans through various measures and international cooperation.

They will also share best practices, promote innovation and boost scientific monitoring and analytical methodologies.

“I’m glad that we, including emerging countries and developing countries, were able to form a broad international framework,” Yoshiaki Harada, Japan’s environment minister, told a news conference.

Japan plans to host the first meeting under the new framework this autumn when officials of environment ministers in the G20 countries are due to meet for the G20 Resource Efficiency Dialogue.
