When the IMO’s regulation to cut SO x emissions went into effect in 2020, LNG became a growing alternative fuel choice for marine transportation. Methane emissions, which can result from the production and consumption of LNG, are linked to significant impacts on air quality by influencing concentrations of ground-level ozone.

Despite clear recommendations from its own science advisors, the US Environmental Protection Agency (EPA) announced over the summer that it will delay its scheduled process to consider strengthening public health standards for ground-level ozone pollution. The stakes over ground-level ozone standard are high.
