Canadian System of Environmental and Resource Accounts - Material and Energy Flow Accounts (MEFA)
Status:
Active
Frequency:
Annual
Record number:
5115
Material
and energy flow accounts record, in physical terms only, the flows of
materials and energy - in the form of natural resources and wastes -
between the economy and the environment. They are directly linked to the
input-output accounts of the Canadian System of National Accounts
(CSNA). This linkage enables the calculation of key indicators of the
resource and waste intensity of economic activity.
Detailed information for 2007
Data release – March 28, 2011
Description
The Material and Energy Flow Accounts (MEFA) record in substantial
detail the annual flows of materials and energy - in the form of
resources and wastes - between the Canadian economy and the environment.
These flows are related to the activities of industries, households and
governments, and they are recorded as such in the accounts. Data for
over 100 industries, plus a wide array of household and government
activities are presented. The MEFA share their classifications of
industries, households and governments with Statistics Canada's
Input-Output Accounts. This allows the environmental data in the MEFA to
be linked directly and easily with the economic data found in the
Input-Output Accounts, adding value to both data sets.
Material and energy flow accounts have been developed for energy use, water use and greenhouse gas emissions.
These statistics are being used in economic-environmental modelling (e.g., the greenhouse gas and energy use accounts have been used when assessing climate change options and economic impacts) and for studies on eco-efficiency and resource and waste intensities (e.g., waste and energy intensity of industrial output, multi-factor productivity analysis). Users are pleased that these accounts are compatible with the traditional national economic accounts, as this greatly facilitates the integration of the environmental data into their macroeconomic models.

Target population
The Canadian economy (persons and unincorporated business, corporations, governments and non-residents).
Instrument design
This methodology type does not apply to this survey.
Sampling
No sampling is done.
Data sources
Data were collected from other Statistics Canada surveys and/or other sources.
All this information is compiled, integrated and analysed as part of
the process of producing material and energy flow estimates.
The main data source is the Input-Output Accounts of the CSNA.
Major suppliers of data within Statistics Canada are Industry Accounts Division, Manufacturing, Construction and Energy Division, Transportation Division and Environment Accounts and Statistics Division. Environment Canada and Natural Resources Canada are the main external data providers.

Error detection
This methodology type does not apply to this survey.
Estimation
The Material and Energy Flow Accounts (MEFA) share their
classifications of industries, households and governments with the
Input-Output Accounts of the CSNA. Empirical development of the MEFA has
been focused on energy, water and greenhouse gases. The methods used to
estimate flows of these resources and wastes in MEFA are described in
the link "Canadian System of Environmental and Resource Accounts -
Material and Energy Flow Accounts: Estimation" in the Documentation
section below.
Quality evaluation
The quality of the estimates produced is ascertained using time
series consistency analysis, as well as analysis of the coherence of the
estimates with current economic events and with related data from other
programs. Issues arising from the source data are also identified.
Disclosure control
Statistics Canada is prohibited by law from releasing any data which
would divulge information obtained under the Statistics Act that relates
to any identifiable person, business or organization without the prior
knowledge or the consent in writing of that person, business or
organization. Various confidentiality rules are applied to all data that
are released or published to prevent the publication or disclosure of
any information deemed confidential. If necessary, data are suppressed
to prevent direct or residual disclosure of identifiable data.
Revisions and seasonal adjustment
Material and energy flow accounts for energy and greenhouse gases are
updated annually. However, since the very detailed Input-Output
Accounts require a long compilation period, preliminary estimates of
those accounts could be published up to 42 months after the reference
year. The water use account has been produced in 1981, 1986, 1991 and
1996.
Material and energy flow estimates are revised when those for subsequent years are published. Revisions are made back one year; they are not normally revised again except when historical revisions are carried out.
Seasonal adjustment is not necessary given that the calculations of material and energy flow estimates are only performed on an annual basis.
