Interestingly, Rw systems value each ton of CO2-eq emitted at
4040 THB, or approximately 134 US$ per ton. Iw and Id systems
value each ton of CO2-eq emitted at 82 and 72 US$, respectively.
These values far exceed the trading price of CO2 set up by the
European Union Emissions Trading Scheme, the first international
emission allowance trading system established after the
Kyoto protocole, which price is the highest compared to other
national systems, and ranged between 16 and 20 US$ throughout
2010.
