請將下面這段話翻譯成英文：

作為世界最大的碳排放國，中國將首次推出旨在減排的碳交易計(jì)劃(carbon trading scheme)。碳交易平臺已在深圳建立，這個平臺將允許企業(yè)購買排放碳的許可。中國還計(jì)劃在另外七個地區(qū)開展類似的計(jì)劃，分析家稱這是邁向全國性的碳交易市場的第一步。但分析家還表示，該計(jì)劃只能涵蓋城市碳排放的38%，不太可能使整體排放量顯著下降。然而，中國的目標(biāo)是到2020年，將碳濃度(carbon intensity)水平降低40%。

參考翻譯:

China, the world's largest carbon emitter, is to launch its first carbon trading scheme aimed at reducing emissions. A carbon trading platform allowing businesses to purchase grant of emitting carbon was established in Shenzhen. China is also planning to cany out similar schemes in seven other areas. Analysts say this is the first step towards a nationwide carbon trading market. But analysts have also said that the scheme which covers just 38 percent of citys，carbon emissions is unlikely to reduce overall emissions significantly. However, China is aiming at reducing the level of carbon intensity by 40 percent by 2020.
