Summit clears air on water. from SMH., page-4

Actually , thats not true. They were referring , in particular, to renewable energy and climate change.

"But the issue of renewable energy and whether countries should commit themselves to setting a target in the percentage of green power sources they use remains unresolved"

"
Finally they reached agreement on one item - that the number of people without access to clean water and sanitation should be halved by 2015."


As the topic clearly states:....Cleared the air on water"..
