This Intended Nationally Determined Contribution comes in advance of a new universal climate change agreement which will be reached at the UN climate conference in Paris, in December this year.
Including Sri Lanka, 156 parties to the UNFCCC have formally submitted their INDCs.
The Paris agreement will come into effect in 2020, empowering all countries to act to prevent average global temperatures rising above 2 degrees Celsius and to reap the many opportunities that arise from a necessary global transformation to clean and sustainable development.
UNFCCC Executive Secretary is encouraging countries to come forward with their INDCs as soon as they are able, underlining their commitment and support towards this successful outcome in Paris.
Governments agreed to submit their INDCs in advance of Paris.
Sri Lanka is largely affected with climate induced extreme weather events and slow onset disasters.
Government disaster relief stood at 130 million dollars between 2007 and 2011.
Officials fear the bill could grow as global warming makes intense storms or failed monsoons more likely.
It plans to shave 7% off forecasts of future emissions in 2030.
That can rise to 23% with help from international partners.
