The article explores how to make energy production better for the environment and the economy in Europe. It looks at various scenarios to see how we can use natural gas to reduce carbon emissions without hurting the economy too much. By balancing costs and environmental goals, it shows that a fair price on carbon can help use natural gas to meet climate targets without costing a lot. This research suggests that if we set the right price on carbon, we can reach our goals without spending too much money, as long as countries work together. The findings also indicate that natural gas can play a key role in achieving climate goals efficiently.
