This document describes Greenpeace's vision as to how to prevent dangerous climate change. Starting from a short analysis of the causes, current impacts and future risks of climate change, we discuss the temperature rise and emission reduction targets required to avoid dramatic and irreversible impacts on ecosystems, the economy and human livelihoods.
Executive summary: Building further upon Greenpeace's Energy [R]evolution scenario we have identified a zero carbon pathway, which describes the potential for deep emission reductions in energy, industry, forestry, agriculture and waste. It also highlights the potential for restoring the land-based carbon sequestration capacity of soils and forests and further reducing greenhouse gas emissions through lifestyle measures.The potential for global greenhouse gas emission reductions, based on current knowledge, is estimated at 80% by 2050, as compared to 1990 emissions. It is clear that in order to prevent dangerous climate change, more reductions will be needed.
