Abstract:

Human activities are threatening to push the Earth system beyond its “planetary boundaries” (1), risking catastrophic and irreversible global environmental change. Action is urgently needed, yet well-intentioned policies designed to reduce pressure on a single boundary can simultaneously, through global economic feedbacks, aggravate other pressures. To understand both the direct and indirect effects of policies in a multi-boundary world, we develop and calibrate a new integrated assessment model of the world economy that incorporates multiple earth system processes. We find that a global carbon tax would have benefits beyond reducing carbon emissions, easing pressure on multiple of the critical Earth system processes. Some pressures would, however, increase and a complementary biofuel policy is needed to remain within the safe operating space.
