global warming potential.

Carbon dioxide, methane and nitrous oxide emissions by branch of activity
In 2014, the greatest quantities of carbon dioxide (CO2) emitted corresponded to Manufacturing
industry, which emitted 75.5 million tonnes, Supply of electrical energy, gas, steam, air
conditioning and water, which emitted 62.4 million tonnes of CO2, and households, which
emitted 62.1 million. As a whole, they represented 77.0% of the total of CO2 atmospheric
emissions.
Agriculture, cattle breeding, forestry and fishing emitted the highest quantities of methane (CH4)
and nitrous oxide (N2O) in 2014. More specifically, it was 17.4 million tonnes of CO2 of
equivalent CH4 (54.3% of the total) and 10.3 million of tCO2e of equivalent N2O (72.0%).
Supply of electrical energy, gas, steam, air conditioning and water was responsible for the
emission of 12.4 million of tCO2e of equivalent CH4 and 1.8 million of tCO2e of equivalent N2O,
representing 38.8% and 12.6% of the total emissions of these gases, respectively.

Methodological note
The National Statistical Institute presents today the estimations corresponding to the period
2010-2014 of the Atmospheric Emission Accounts base 2010.
The Environmental Accounts (EA) are a synthesis statistical option with the general objective
of integrating environmental information coherently in the central system of National Accounts,
following the methodology of the United Nations' System of Integrated Environmental and
Economic Accounting (UNSD), which constitutes the conceptual framework of the EA.
Regulation (EU) No 691/2011 of the European Parliament and of the Council of 6 July
2011 on European environmental economic accounts, constitutes the reference framework
of concepts, definitions, classifications, and common accounting regulations whose purpose is
to draft Environmental accounts and incorporates a module on this account, for annual
transmission.
The Air Emission Accounts present the data regarding the polluting emissions into the
atmosphere, in a way that is compatible with the System of National Accounts, registering the
emitting agents, broken down by branch of economic activity and Households as final
consumers.
The estimates of the Air Emission Accounts are carried out using the National Air Emission
Inventories, compiled by the Ministry of Agriculture, Food and the Environment, using the
EMEP/CORINAIR methodology developed by the European Environmental Agency, with the
SNAP nomenclature (Selected Nomenclature for Air Pollution), which groups emissions
functionally, by process.
The Inventories present the emissions of all of the sources in the country, regardless of whether
they are domestic economic activities (principle of residence) or not. Moreover, it includes the
emissions of non-economic agents (nature) and the absorption of substances by nature (carbon
by biomass). In order to prepare the estimates for the Emission Account, it is necessary to
adapt the emissions to the principles of the System of National Accounts.
Regarding the distribution, by branch of activity and Households as final consumers, most of the
inventory categories correspond to a single economic activity registered in a branch of activity,
but in certain cases, the emissions must be divided into several branches (combustion plants,
transport and other). Since atmospheric emissions are distributed by branch of economic
activity in accordance with the rules of the National Accounts system, those resulting from
secondary and auxiliary activities are grouped with those of the main activity of economic units.
Households as final consumers considers the direct emissions corresponding to their own
transport, heating and other emissions of a secondary nature.
