THEORYANDPRACTICEINTHELOW-CARBONECONOMY
Theideaofalow-carboneconomyisrelatedtothebasicmaterialcyclesonEarth,especiallythecarboncycleandcarbonbalance.Withinagivencarbonbudget,onemaycalculatevariouspublicandcommercialactivitieswithregardtotheircarbonemissions,andusemarketmechanismsfortradingrightsforcarbonemissions,eitherdomesticallyorinternationally,throughmechanismsintheKyotoProtocol.Athoroughreconsiderationofeconomicandsocialactivitieswithregardtothecontrolofgreenhouse(GHG)emissionsmayallowacompletetransformationofthesysteminlinewithlow-carboneconomictheory,andthereforemayprovideasustainablesolutionforglobalclimatechange.Inmanycountries,greatprogresshasbeenmadeinscientificresearchtounderstandtheimpactofhumanactivitiesoncarbonemissionsintermsofinternationalresearchonglobalclimatechanges(Zhao2006).
