The government will announce an ambitious plan aimed at cutting disposable plastic waste by 25 percent over the next decade while promoting environmentally friendly bioplastics made from plants, sources said Saturday.

By setting the goal, Tokyo aims to display its commitment to tackling environmental issues ahead of the Group of 20 summit in Osaka next June.

Japan produces the largest amount of plastic waste per capita after the United States and has lagged behind other countries in curbing the use of plastics.
