is it possible to increase the size of leaves of a tree, so the plant can absorb more carbon di oxide?

Question

As most of the countries talk about planting tress and other methodologies
To reduce the effect of global warming, why can’t we genetically modify a
Tree/plant so that it bears leaves of very huge size, which inturn facilitate it to absorb or capture more
