Presently, about 25 percent of global emissions are from all agricultural activities. The global potential of soil C sequestration through modification of agricultural practices is 21 to 42 Gt over a 50-year period. Soil carbon sequestration is a win-win strategy because it increases agricultural productivity, improves water and air quality, and reduces the rate of enrichment of atmospheric CO2. The Eco-indicator has been developed by a large team of experts during 1997 till 1999. The project was commissioned by the Dutch Ministry of Urban Planning, Housing and the Environment as part of the Product Oriented Environmental Management policy.
Weighting is considered to be the most controversial step in life cycle impact assessment.
In the Eco-indicator 99 project the weighting step is performed by using a panel in a carefully performed written procedure. All efforts were made to make this step as straightforward as possible. Emissions Limits could Benefit Developing Countries Developing countries can benefit greatly by joining a worldwide agreement to control greenhouse gases, the White House argues in its annual Economic Report. Most scientists have concluded that greenhouse gases are contributing to the global warming that is now taking place. But to make worldwide trading possible the developing countries would have to accept emissions limits, without which allowances would have no meaning.
