JWEE sources: INSEE Housing Survey
The removals of fuelwood are estimated according to the « French methodology »presented to Eurostat's Forestry Statistics Working Group, 26-27 November 2009(reference Doc. Forest/2009WG/05).
Since 1955, the French National Institute of Statistics and Economic Studies (INSEE)has carried out every 4 or 5 years a "Housing Survey". The last one was implementedin 2006 on a sample of 43000 dwellings (main residence, ordinary dwellings, notincluding collective lodgings such as old people’s homes, boarding schools, barracksand mobile homes).
It includes some questions about the sanitary equipments and the heating systems, inparticular the wood-burning appliances (boilers, kitchen cookers, wood-burningstoves, open fireplaces, closed hearths, inclosed glass fronted room-heaters etc.).Since 1992, the fuelwood users have been required to state the quantity of fuelwoodthey consume.
In 2006, more than one house out of three (5.4 millions i. e. 36%) was fitted with aheating system using wood. Less than 2% of the flats (170000) used wood.

JWEE sources: INSEE Housing SurveyConsumption of wood (for the households that have stated to have a fireplace or to use fuelwood)
KBST - How much FUELWOOD do you estimate you use yearly? (choose the unit)1 - steres (1 stere = 1 m3 or 1000 litres)2 - litres
KBST1 - How much FUELWOOD do you estimate you use yearly?(in steres) or (in litres)
[1 to 999]KBSC – Is the used wood …
- bought completely?- bought partially?- obtained free of charge?
The knowledge of the total number of wood-burning appliances and of the related consumptionsmakes it possible to estimate the average consumption for each type of wood-burning appliance.The wood consumption in households provided by SOeS is aligned on the results of HousingSurveys (number of appliances x unit consumption).
Between two Housing Surveys, SOeS estimates the evolution of the total number of appliances byusing the annual sales of each type of new appliances and the replacement rate of old ones(annual study Observ'ER/Ademe).
Estimated consumption = updated total number x unit consumption

The last problem to solve is the origin of the wood. To answer this question, a studycarried out by Arthur Andersen in 1999, on behalf of ADEME and the associationNormandy-Biomass, is available. That study included a telephone survey of 1200households aiming at defining the origin of their fuelwood supply. The global resultswere consistent with those of the Housing Survey 1996.

JWEE sources - Table I: Wood waste

Data sources :
National Federation of pellets and briquette producers and National Federation of wood charcoal producers are enquired in order to know : • the production of processed wood fuel, • the origin of wood (sawdust, other by-products, roundwood) • the use of the production (household, heating plants) • the international exchanges (import/export). These last data are compared to official data from Customs statistics.

JWEE uses: INSEE/SSP EACEI(1) Survey
Since 1982, a mandatory survey is carried out by INSEE(industry exc. food and sawmills) and SSP (food industry andsawmills) on 12000 industrial units. Since 2005, some newquestions aim specifically at knowing the consumption ofwood, solid by-products and black liquor (in tonnes) along withtheir use (manufacturing, autoproducer of electricity,autoproducer of heat).Table IV in JWEE is filled with the results of this surveyconverted in TOE: autoproducer of Heat, CHP and Electricity.

JWEE uses: ADEME data on heating plants
ADEME is in charge of the management of the incentivesgranted by the national and local authorities for wood heatingplants.Since 1994, it collects data on all new equipments receivingincentives: location, existence of an urban heating system,power (MW) and consumption (TOE) by type of fuelwood(roundwood, forest chips, industrial by-products, pellets, etc.).In 2011, these data were updated for all heating plantsproducing more than 100 TOE.Table IV in JWEE is filled with these updated data: MainActivity Producer of Heat.

JWEE Table IV : crossing sources and uses.
How to distribute consumption between resources?
Data sources give mainly the total consumption by sector (heat producers, CHP production by industries, residential, etc.) and the wood source is generally unknown.
Method : Total intake of each user is broken down with an allocation key between the different sources of wood.
The allocation is found in studies if they exist or defined by expertise.
22
JWEE Table IV : crossing sources and uses.Consumption breakdown between resources.
Example of Main activity producers of heat
Data available :• Total consumption of fuelwood by heating plants (SOeS Enquiry) • Origin of wood used by heating plants (ADEME database on heating plants wood supply in 2006) which constitutes an original distribution key.• In 2009, the distribution key had to be modified: Forest chips production has been multiplied by 4 since 2006, sawnwood by-products are nearly completely absorbed by pellets production. The distribution key was modified by expertise.• Pellets and briquettes consumption : 5 % of national consumption (National Federation of pellets producers ). This use did not exist in 2006. Assumption: this is a new resource. The rest of wood consumption is dispatched between the different sources with the distribution key.

Example of residential fuelwood consumption
Data available :• Total consumption by residential consumers (INSEE, SOeS)• Allocation table of fuel wood by origin (forests / trees outside forests / recovered): Andersen Study 1999.
• Pellets and briquettes consumption : 95 % of domestic consumption is for residential usage. (National Federation of pellets and briquette producers) As pellets and briquettes did not exist in 1999, we have considered that : 1) Fuel wood from outside forest is own-consumed and is not replaced by pellets; 2) Pellets replace a part of fuel wood from forests.
Wood charcoal is mainly used for outside cooking (barbecues) and not for heating.

Pellets and briquettes were first substituted to forest fuelwood 5 years ago.

Final checking of consistency with harvest
26
At the end of the process, the experts check that the total consumption of each source islower than or close to their availability.
For residential consumption, a problem appears: there is a gap of 3.3 million tonnes d.m.between total primary solid biomass consumption: 15.4 million tonnes d.m.(1) [includingbark] and harvest: 12.1 million tonnes d.m.(2) [not including bark].
The difference is mainly due to bark which is burned with the wood and not distinguished byenquiries. This volume is estimated to 2.6 million tonnes d.m.
There remains 0.7 million tonne d.m. which can be due to uncertainties in enquiry results(volume, origin), to conversion factors and to changes in inventories.
The assumption is that primary wood consumption by heat producers and industries areaccurate and that uncertainties come from residential final uses. Excess consumption ofprimary wood has been subtracted from wood from forests and registered as unspecifiedsolid co-products.(1) 15.361 Mt d.m. = 0,272 (Main Activity Heat Producer) + 0,593 (Autoproducer Heat, CHP & Electricity) + 10.543 (Direct final consumption: residential fromforests) + 3860 (Direct final consumption: residential from trees outside forests) + 0,093 (Direct final consumption: Agriculture, Forestry & Fishing)(2) From Table I: 18.477 x 0,455 + 6.599 x 0,560
JWEE Table IV : crossing sources and uses.Final checking of consistency
27
Categories of national enquiries are frequently not exactly the same as JWEE categories : a convergence should be sought.
National enquiries do not ask the origin of wood used for energy use. It would be necessary to introduce this question in the surveys.
Units : Data are collected generally in tonnes without reference to watercontent. The conversion in TOE or in dry matter is difficult andinaccurate. Water content is difficult to obtain, the nature of the woodproduct is not known with enough precision. An average water contentrate could be applied for the conversion into the required unit.
Allocation keys are frequently outdated : new ones are required, some will be available in the near future.

28
JWEE and the monitoring of the Forest Sector
The JWEE approach is an opportunity:- to get the best possible data on wood energy (sources and uses)and make them consistent,- to be ready to develop the methods and the surveys,- to make sure of the traceability of the calculations (a method notemust be written),- to endeavour to retropolate the series whenever possible.It is also an opportunity to initiate a follow-up of wood energy whichwill be mandatory for all and will provide data to NREAP and to anobservation tool wider than wood energy.The next step is to integrate the data of JWEE in:- the economic monitoring tool of the forest sector,- the French national observatory of biomass resources.
