EUAs are emission rights released by the government of
the EU member states upon the request of companies
affected by EU emission trading.

CERs are emission rights derived from CDM climate
protection projects. They can be used in line with EU
emission trading in order to fulfil reduction obligations
in the second and third trading period up to a certain
limit, which is individually defined for each country.
