A report last year by the non-profit Climate Policy Initiative found Africa has received only 12% of the finance it needs to cope with climate impacts.
The thousands of delegates are expected to debate solutions ahead of a U.N. climate summit next month in New York in September and the COP28 U.N. summit in the United Arab Emirates from the end of November.
The summit's organisers also say they expect deals worth hundreds of millions of dollars to be concluded in Nairobi.
In June, it hosted an auction where companies from Saudi Arabia bought more than 2.2 million tonnes of carbon credits.
One project generating carbon credits in Kenya is BURN Manufacturing's production of clean cooking stoves to replace heavily polluting wood and charcoal-based fires.
