UnderstandingMethaneandItsEnvironmentalImpact
Methaneisacolorless,odorless,andflammablegasthatoccursnaturallyintheEarth'satmosphere.Itisalsooneofthemostpotentgreenhousegases,withawarmingpotential28timesgreaterthanthatofcarbondioxide(CO2)overa100-yeartimeframe.Understandingthesourcesandimpactsofmethaneemissionsiscrucialtodevelopingstrategiesforreducingourgreenhousegasfootprintandtacklingclimatechange.
