Both Mr. S. P. K. Amarasinghe, the Chief Training Engineer and Mr. N. P. Gunatilake hope that as time goes by greater awareness can be created about these reclamation centers and that more people will start utilizing this service.

The Montreal Protocol has since been strengthened greatly through subsequent amendments and adjustments, supported by ongoing research, which has enhanced our understanding of the ozone loss. As of end-2014, the Montreal Protocol has helped successfully eliminate over 98% of controlled ozone depleting substances, helping reverse the damage to the ozone layer. Despite these successes, challenges still remain. CFCs were replaced by the less damaging hydrochlorofluorocarbons, which is now being systematically replaced by hydrofluorocarbons (HFCs). Though HFCs do not contribute to ozone depletion, they are potent greenhouse gases contributing to global warming and climate change. While the Vienna Convention has been quite effective with regards to controlling the ozone damage, unfortunately the need for action has exponentially grown. The renewed call on humanity to take action, not tomorrow but today, is for similar strong agreements. COP21, or the upcoming 21st session of the Conference of Parties (COP21) of the UN Framework Convention on Climate Change (UNFCCC) in Paris in November this year, is an opportunity for the global community, to stand tall, be bold, agree and take action.

Hopefully, then the world development, will be truly sustainable.
