As the Kyoto Protocol established serious commitments to
curtail greenhouse gas emissions, transposition of the EU
Emissions Trading Directive took place in Portugal,
implementing an emission allowances trading scheme and
providing the necessary framework within EU guidelines.
According to Portuguese rules, operators and industrial
installations responsible for greenhouse gas emissions must
hold, and surrender at the end of each year (or April 30 of the
following year at the latest), allowances proportionate with
their total emissions over the previous year.
The rules apply to installations operating in the energy
sector, iron and steel production and processing. The mineral
industry and the paper and card industry will also be subject
to the emission-trading scheme. These industries will only be
allowed to function if they hold an emission allowance, which
is a certificate entitling its holder to emit a tonne of carbon
dioxide or an amount of any other greenhouse gas with an
equivalent global warming potential during a specified
So the operator - any person, natural or legal, who
operates or controls an installation or to whom decisive
economic power over the technical functioning of the
installation has been delegated - should hold as many
allowances as its certified greenhouse gas emissions.
From May 1 2008 and for four months into each new five-year
period, allowances that are no longer valid but were not
surrendered by their holders will be officially cancelled by
the Institute for the Environment, who is also responsible for
allocating new allowances to replace cancelled ones.
