According to wikipedia...

The United Nations Climate Change Conferences are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC).

They serve as the formal meeting of the UNFCCC parties (Conference of the Parties, COP) to assess progress in dealing with climate change, and beginning in the mid-1990s, to negotiate the Kyoto Protocol to establish legally binding obligations for developed countries to reduce their greenhouse gas emissions.

Starting in 2005 the conferences have also served as the "Conference of the Parties Serving as the Meeting of Parties to the Kyoto Protocol" (CMP); also parties to the convention that are not parties to the protocol can participate in protocol-related meetings as observers.

From 2011 the meetings have also been used to negotiate the Paris Agreement as part of the Durban platform activities until its conclusion in 2015, which created a general path towards climate action.

The first UN Climate Change Conference was held in 1995 in Berlin.

Each time I see activists especially in developing nations, campaigning against the use of fossil fuel, I wonder what they are up to..

A country like Nigeria should focus on eliminating gas flaring & oil spillage..etc

See the post President Buhari shared before leaving for Glasgow:

...& See what association of petroleum explorationists said...

Nope, not now.

The answer is NO.

Other means of generating power are expensive compared to fossil fuels

Even with the cheap fossil fuel, country like Nigeria are still in darkness
