碳(tan)中和是指企業(ye)在一定時間(jian)內直接(jie)(jie)或(huo)間(jian)接(jie)(jie)產生(sheng)的(de)二氧(yang)化碳(tan)或(huo)溫室氣體(ti)排(pai)(pai)放(fang)總量，通過植樹造林、節能減排(pai)(pai)等(deng)形式，以抵(di)消自身產生(sheng)的(de)二氧(yang)化碳(tan)或(huo)溫室氣體(ti)排(pai)(pai)放(fang)量，實現正負抵(di)消，達到相對“零排(pai)(pai)放(fang)”。

從(cong)企業性質來看(kan)，中(zhong)國碳(tan)中(zhong)和企業排名榜(bang)中(zhong)有32家(jia)(jia)國有企業，18家(jia)(jia)民營企業。地(di)區分布(bu)上，東部地(di)區50強占比(bi)更多(duo)，但區域間(jian)碳(tan)中(zhong)和貢獻力無明(ming)顯差異，水平(ping)均衡(heng)。

分行(xing)業來看，中(zhong)(zhong)(zhong)(zhong)(zhong)國企(qi)業碳中(zhong)(zhong)(zhong)(zhong)(zhong)和貢獻力排行(xing)榜中(zhong)(zhong)(zhong)(zhong)(zhong)的傳統(tong)能(neng)源(yuan)企(qi)業，以中(zhong)(zhong)(zhong)(zhong)(zhong)石(shi)化、中(zhong)(zhong)(zhong)(zhong)(zhong)石(shi)油為代(dai)表；新能(neng)源(yuan)企(qi)業以隆基綠能(neng)為代(dai)表；能(neng)源(yuan)產業鏈企(qi)業以協鑫集(ji)團和陽(yang)光(guang)電(dian)源(yuan)為代(dai)表；電(dian)力企(qi)業以中(zhong)(zhong)(zhong)(zhong)(zhong)國華電(dian)、國家電(dian)網、中(zhong)(zhong)(zhong)(zhong)(zhong)國華能(neng)為代(dai)表。
