Some key G20 countries must immediately submit their intended contributions for the upcoming Paris climate talks, said Miguel Arias Canete, European Union (EU) Commissioner responsible for Climate Action & Energy on Thursday.

"Key G20 countries, such as Argentina, Brazil, India, Indonesia, Saudi Arabia, South Africa and Turkey, must submit their intended contributions without delay," said the Commissioner in a press conference here, ahead of the United Nations climate change conference scheduled for later this year in Paris.

The EU submitted its Intended Nationally Determined Contribution in March, in which it pledged to reduce its greenhouse emissions by at least 40 percent by 2030 compared to 1990 levels, said the Commissioner.

Moreover, major countries including China and the United States also have submitted their pledges.

The Commissioner pointed out that only 56 countries have handed their pledges so far, only representing over a quarter of all the countries, which was "not so good news."

"It is clear that there is a strong political will to reach a climate change agreement," said the Commissioner. "The technical talks are seriously lagging behind political discussion. And this must be changed." Endit
