It's not easier - as I understand it, the leaks are tiny amounts along the entire length of the pipelines. Getting an absolutely perfect seal is something that's expensive to do, whereas in theory the CO2 footprint of coal is concentrated and therefore much easier to capture. In practice, doing either of those will spike the price of the energy, and the only reason to use them over renewables is their being cheap, so it won't happen.
