绿色国内生产总值，缩写为GeGDP，简称为绿色GDP，是一个以经济增长和环境因素综合起来的一个指数。

绿色GDP的值小于GDP的值，即GeGDP的值等于在现行GDP核算值的基础上，再减去以下两项数值：一项称「资源耗减成本」（这里讲的资源主要指土地、森林、矿产和水），另一项称「环境降级成本」（是指因环境破坏引起环境等级下降而应计入的成本。绿色GDP的公式表达为：

　GeGDP = GDP - 资源耗减成本 - 环境降级成本。

The green gross domestic product (green GDP) is an index of economic growth with the environmental consequences of that growth factored into a country's conventional GDP. Green GDP monetizes the loss of biodiversity, and accounts for costs caused by climate change. Some environmental experts prefer physical indicators (such as "waste per capita" or "carbon dioxide emissions per year"), which may be aggregated to indices such as the "Sustainable Development Index".
