New Delhi (Agencies): Urging global community to overcome mutual differences and join hands to contain climate change, the government on Friday appealed them to remove barriers on technology transfer for the benefit of poorer nations fighting environmental degradation.

Addressing a session of the Delhi Sustainable Development Summit, New and Renewable Energy Minister Farooq Abdullah said, "This is a small world. Unless we protect it... if we think I have to protect myself and not the other person, we are failing to understand the tragedy that is going to befall our children."

Abdullah underlined the need for an "honest" approach by the nations to address the issue or else "we would be wasting our time."

"We should meet this challenge by working with each other; remove the barriers of technology transfer. It would be impossible for poorer nations to afford those devices that are needed to protect the environment," he said.

While a few nations were of the view that subsidies should be removed from fossil fuel given its increased usage and impact on environment, Abdullah felt such a move could hamper growth and development of poorer nations like India where diesel is widely used in the agriculture sector.

He said while the Jawaharlal Nehru Solar Mission has been launched to generate 20,000 MW of solar power by 2022, the government was exploring the possibility of using geo-thermal energy in areas with wide use of diesel.
