Abstract: | The paper reviews base year emission inventories, driving forces, and long-term scenarios of sulfur emissions as background material for developing a new set of IPCC emissions scenarios. The paper concludes that future sulfur emission trends will be spatially heterogeneous (decline in OECD countries, rapid increase particularly in Asia) and therefore cannot be modeled at a global scale only. In view of ecosystems and food production impacts future sulfur emissions will need to be increasingly controlled also outside OECD countries. As a result, future sulfur emissions are likely to remain significantly below the values projected in the previous IPCC IS92 high emissions scenarios. |
