From next year, the USA’s Environmental Protection Agency will require operators of large carbon-emitting operations to submit annual emissions reports for carbon dioxide, methane, nitrous oxide, and other greenhouse gases. These firms will require analytical tools to monitor their emissions and to create estimates based on energy consumption. But they face a dilemma on how they will gather the data.

Equally important are the tools to determine levels of harmful gases in the general environment. Published online in Analytical Methods, Jason Horn and colleagues use Clark-type amperometric gas sensing methodology to investigate hydrogen sulfide in the air:
