It's barely a month since global leaders reached a landmark deal to bring climate change under control but now the hard work has begun over how to actually reduce countries' and companies' carbon footprints, business and energy leaders told CNBC.
In December, leaders met in Paris for the United Nations' COP21 climate change conference where they agreed to legally binding deal on limiting greenhouse gas emissions. The deal, signed up to by 195 countries, aims to limit global temperature increases to "well below" 2 degrees Celsius above pre-industrial levels and for more developed countries to assist poorer ones in achieving that.
A month after the deal was signed, Christiana Figueres, executive secretary of the UN Framework Convention on Climate Change told a CNBC panel at the World Economic Forum (WEF) that now's not the time for celebration.
COP21 did surpass my expectations but before we sit here and congratulate ourselves I think the success is not yet on the table," she told CNBC's WEF panel and audience on Wednesday.
"Because whether Paris is successful is going to depend on how we interpret and how we act upon the very strong signals that came out of Paris, we need to keep that in mind. (The deal) was the easy part and now comes the difficult part."
