Tokyo, March 6 (IANS): The Japanese government will not meet its future carbon reduction targets if it continues to base its energy mix on a significant share of nuclear power, Greenpeace warned on Friday.

On the eve of German Chancellor Angela Merkel's arrival in Japan, the organisation has urged her to promote the German Energy Transition (Energiewende) during her visit.

She will be visiting Japan from March 8 to 10.

Chancellor Merkel is attempting to secure national climate change commitments from Japan and other Group of Seven nations ahead of the G7 summit to be held in Germany in June.

The Abe government has yet to make a national climate commitment as it has so far failed to announce its energy share for 2030.

The ministry of economy, trade and industry is currently deliberating a 15-25 percent nuclear target and a 20 percent renewable target by 2030, with a decision to be reached before the G7 summit.

"Prime Minister Abe's nuclear energy policy lacks credibility and undermines renewable industry investments, despite Japan's massive renewable energy potential," energy campaigner with Greenpeace Japan Hisayo Takada said in a statement.

"In addition, the flawed assumptions of Japan's energy policy will result in the importation of vast and expensive fossil fuels. Chancellor Merkel should understand that with its present obsession with nuclear reactor restarts, the Abe government won't be able to achieve Japan's climate targets."

In contrast to German society and government, Japan's government is simply ignoring the important lessons of the Fukushima nuclear disaster, Takada added.
