ROME, Sept 29 (Reuters) - Italian Prime Minister Giorgia Meloni and her Czech counterpart Andrej Babiš will agree joint proposals to curb energy costs and overhaul the European Union's carbon market, officials from Rome said ahead of a meeting of the leaders in Prague on Tuesday.

They aim to present the reform package at an October 15-16 EU summit, the Italian officials said.

Global supply disruptions due to the conflicts in Ukraine and the Middle East are fuelling voter discontent over rising living costs. Parliamentary elections are ​due next year in Italy, France and Spain among others.

Meloni and Babiš are focusing on easing European Union rules that they say could cause energy supply disruptions while also reforming the EU Emissions Trading System (ETS), a regulation forcing power plants and industries to buy CO2 permits when they pollute.

As part of the package, Rome and Prague are calling on the EU to temporarily suspend a regulation on methane which, according to the officials, could make it more difficult to rely on alternative gas suppliers from January, potentially increasing energy costs and threatening security of supply.

The two governments want the EU to act through a so-called 'Market Stability Reserve' or MSR to prevent the ETS mechanism from contributing to increased cost pressures on businesses.

The MSR is a system that takes excess CO2 permits out of the carbon market to avoid it being oversupplied and the carbon price crashing - but it can also release spare permits back into the market to cool off price spikes.

Other proposals include postponing the 2028 launch of an EU carbon price for transport and heating fuels, known as "ETS2", to prevent further increases in energy bills.
