NEW DELHI: The principle of common but differentiated responsibility and equity - right to grow - is central to talk of global environmental agreements and their effective implementation, said environment minister Jayanthi Natarajan on Friday.

Speaking at the 12th Delhi Sustainable Development Summit, Natarjan said: "There is no doubt that the global regime for protecting biodiversity has to be ambitious but it has to be firmly rooted, at the same time, in Rio principles.

"The principle of common but differentiated responsibility and equity is something that is extremely relevant when we talk of global environmental agreements and their effective implementation. They are vital to the success of any global agreement in the field of environment," she said.

Talking about the outcome at climate change talks in Durban last year, she said: "In Durban, we took some very important decisions to advance the international actions on global climate change.

"Our goal should be to ensure that the outcome of the ensuing negotiations under Durban platform is firmly founded on these principles and that we avoid pitfalls in implementation that such agreements have suffered in the past," she added.
