"Some of the main proposals in a draft text for negotiation at a U.N. sustainable development conference next month are being watered down at informal talks in New York, observers said on Tuesday, heightening fears the summit will fail to deliver."
"The Rio+20 summit in Brazil from June 20-22 is expected to draw more than 50,000 participants from governments, companies and environmental and lobby groups.
It will try to hammer out sustainable development goals across seven core themes including food security, water and energy but is not expected to produce mandatory targets.
Informal talks are taking place in New York until Friday to shape the main negotiating text."
