UN climate negotiators have met in Peru to finalise a new global emissions pact.
A global climate agreement between 195 countries will come into play by the end of 2015 in Paris, and representatives of the nations have met in Lima to discuss terms and conditions.
Climate delegates have been buoyed by the changes in political attitudes towards global warming in 2014, and will be hoping to use the next two weeks to finalise key negotiating texts that will act as the basis of the deal.
However, despite progressive thinking by the globe's economic leaders, experts believe that everyone will have to play their part.
The BBC has quoted Paul Bledsoe, a senior climate fellow with the German Marshall Fund of the US, as saying: "Ultimately this is not a problem that can be solved by just the US, China, and the EU.
"There's a whole series of countries - Canada, Australia, Japan, Russia, South Africa, Brazil and Indonesia - who have not made commitments (to cut emissions) and we don't know yet how robust their commitments are."
By March 2015, all nations involved in the process will announce what action they will be taking to cut emissions.
There has been significant positive momentum this year with several high profile decisions being made in the war against climate change.
For example, the EU agreed its climate targets for 2030, and China has said that its emissions would peak in the same year.
