A group of scientists monitoring climate action said Wednesday that the emissions-cut pledges presented so far by countries will fail to put the world on the path to limit global warming to below an international target, with the submissions by seven countries including Japan judged as "inadequate."

In a report by independent science analysis body Climate Action Tracker, it said the pledges by Japan, Australia, Canada, New Zealand, Singapore, South Korea and Russia were "not considered to be a fair contribution" to the goal of holding warming to below 2 degrees Celsius "from almost any perspective."

Following international negotiations, countries across the world have committed to making pledges — called intended nationally determined contributions, or INDCs — to the secretariat of the United Nations Framework Convention on Climate Change.
