Global and regional surface nitrogen balances in intensive agricultural production systems for the periode of 1970-2030
The major conclusion of the paper is that despite the expected improvement of the efficiency in many countries, it is clear that the fast increase of production and intensification between now and…
A multi-gas abatement analysis of the Kyoto Protocol
An updated analysis of the costs of the Kyoto Protocol, now based on a multi-gas approach, accounting for all six Kyoto gases, shows that, in addition to reductions of CO 2 , a large share of the…
Multi-gas emission pathways for stabilising greenhouse gas concentrations
Stabilizing greenhouse gas concentrations 450 CO 2 equivalent or lower requires global emissions to peak within the next two decades, followed by substantial overall reductions by as much as 30 to 50%…
