France is the host country of this year's UN Climate Change Conference.
After holding discussions with Environment Minister Prakash Javadekar, visiting French Foreign Minister Laurent Fabius also said arriving at a consensus by 195 countries on the climate deal "is a very important and difficult matter."
"If we want and we want to have success the question on finance and the question of technology must be dealt with," Fabius, who is the President of the twenty-first session of the Conference of the Parties (CoP 21), said responding to a query on the concerns raised by the developing nations.
"When you are discussing with different countries, you need transfer of technologies... It is the way to go and it is necessary for the development of both developing nations and rich nations," he said.
Operationalisation of the USD 100 billion Green Climate Fund (GCF) and access to clean technology at an affordable cost are among the key demands by developing nations including India from developed countries which are historically responsible for climate change.
Earlier, inaugurating the 15th Delhi Sustainable Development Summit (DSDS) organised by The Energy and Resources Institute (TERI) here, Fabius asked the international community to work together on climate change and not against each other.
He warned that a significant reduction of greenhouse gas emissions is not achievable without equitable access to sustainable development.
Noting that 2015 will be a "defining moment" as far as climate change is concerned, the French Minister also made an impassioned plea to the nations to agree on major issues before assembling in Paris later this year for inking a deal to limit global warming to below 2 degrees Celsius.
Fabius also referred to the report produced by IPCC, a UN-appointed panel, which has "confirmed that climate change, or rather climate disruption, is a threat", and said that the world should "act now" to deal with it.
"The scientific community has done its job - it is now to governments, businesses, civil society to act," he said.
