New York City was struck Wednesday morning by a tragic building explosion in Harlem that has, at latest count, killed at least seven people and injured 60 more. Being a New York City resident, my first thought, selfish as it may be, was, “How do I prevent something like that from happening to my building?”

As it turns out, there is something we could do to prevent more disasters like this from occurring, and it would also be good for lowering greenhouse gas emissions.

The cause of the explosion was a natural gas leak. Just a day earlier, as Capital New York notes, the Center for an Urban Future (CUF), a New York City-focused think tank, issued a report on New York’s decaying infrastructure. Among the problems it identified: leaky pipes carrying natural gas.
