But as electric vehicle sales surge, might the end of the oil age be closer than delegates think?
Experts are bringing forward their predictions for so-called "peak oil" - the moment when crude consumption finally starts to fall.
The International Energy Agency - IEA - now expects that moment to come in 2030 - 10 years earlier than it previously forecast.
Oil giant BP has also brought forward its forecast date.
And it's all to do with how we get about.
Transport accounts for about 60% of oil demand, according to the IEA.
But EVs are now expected to account for close to a half of global vehicle sales by the end of the decade.
The Cybertruck from Elon Musk's Tesla is just one of many new offerings:
"And finally, the future will look like the future."
China is leading the way on sales, partly thanks to big subsidies for new zero-emission vehicles.
EV sales in the U.S. are far behind, but rising.
Some fear the electric revolution could run out of juice.
General Motors, Ford and other big names have recently delayed or scrapped plans to ramp up output of EVs.
They say rising labor costs and high interest rates are making the cars too costly for consumers.
Many countries are also short of charging stations, and subsidies could be phased out.
Even so, the cost of batteries is falling fast, and that could make EVs cheaper than regular cars.
While that has some experts optimistic, there's a long way to go.
The IEA says EV sales need to hit 70% of the total market by 2030, if the world is to hit targets set by current climate accords.
