Actions such as emission reduction and financial aid are needed to make the historic Paris Climate Agreement a successful one compared to the Copenhagen Accord, whose promises have not been met.
"Substantial and sustained emission reductions are needed to limit climate change based on the fifth assessment report of the Intergovernmental Panel on Climate Change," said Andrej Kranjc, an expert in climate change, during a relevant lecture at University of International Business and Economics on Monday night.
The fifth assessment report showed human influence being the dominant cause of the observed warming. The atmospheric concentrations of carbon dioxide, methane, and nitrous oxide have increased to levels unprecedented in last 800,000 years.
By 2010, China and the US are the world's top two countries in terms of greenhouse gas emissions. The report warned that without additional efforts to reduce greenhouse gas emissions today, emissions are going to continue to climb due to the growth in global population and economic activities.
At the Paris Climate Change Conference, participants all agreed to take responsibilities and leave a better living environment for upcoming generations.
As for reaching the goal of holding the average temperature rise below 2 degrees Celcius, "all countries need to contribute, developed countries must lead the way, but without participation of all countries, particularly the biggest emerging economies such as China and India, it's not possible to reach that," said Kranjc, who also gave a brief introduction to European Union's actions on mitigating climate change.
"China has become the world's largest investor in clean energy, spending $89.5 billion, or 29 percent of the world total in 2014", said Kranjc, besides introducing actions undertaken or planned by China in the future years.
"And one of the most important things in implementing the Paris Climate Agreement is to ensure developed countries will provide $100 billion a year by 2020 to help developing countries transform their economies to cope with climate change. Success is within reach, however it is not guaranteed. A lot of work and politics will be needed, trust between rich and poor, developed and developing, financial and technological assistance to developing countries. And we need to act quickly, otherwise we'll miss the last train", said Kranjc.
