About 2,800 police and soldiers have been deployed around the conference site and over 6,000 have been deployed in the city.
Bitterly divided negotiators from nearly 150 countries began talks on Tuesday on a landmark deal to cut Earth-warming greenhouse gas, amid rising emissions and 2015 threatening to be the hottest year ever recorded in history.
The talks started on Tuesday a day after the heads of over 150 nations, including Prime Minister Narendra Modi, gathered in France in a bid to provide a political push for a powerful climate deal.
The summit is being held under the shadow of the deadly Paris terror attacks that killed 130 people two weeks ago.
About 2,800 police and soldiers have been deployed around the conference site and over 6,000 have been deployed in the city. The 12-day conference will, for the first time in over 20 years of UN negotiations, aims to achieve a legally binding and universal agreement on climate, with the aim of keeping global warming below 2 C over pre-industrial temperatures.
Scientists estimate that if the world warms by more than 2 C on average above pre-industrial levels by the end of this century, the effects of climate change will become catastrophic and irreversible. A 2 C limit has long been the goal of UN climate summits, and current pledges from all countries are estimated to lead to warming of 2.7 C to 3 C, although the proposed deal has a provision for increased
emissions cuts in future.
Countries like China and India have laid out plans for cuts or curbs to their emissions. These will form the centrepiece of any historic climate deal. The most difficult issues include working out how to share the burden of taking action between rich and poor nations, how to finance the cost of adapting to global warming and the legal format of any final text.
More than 180 countries have submitted their plans to reduce the harmful emissions that cause climate change. The UN climate process concerns the use of fossil fuels, the backbone of the world's energy supply -- and that puts the interests of developing nations at stake.
Prime Minister Narendra Modi has cautioned against any unilateral steps that will lead to an economic barrier in the battle against climate change and hoped that the developed countries would mobilise USD 100 billion annually by 2020 for mitigation and adaptation.
"The principles of equity and common but differentiated responsibilities must remain the bedrock of our collective enterprise," Modi told the world leaders yesterday addressing the UN Climate Change Conference, also known as the COP21, which stands for the 21st annual "Conference of Parties".
