Scope 3<\/a><\/a> du bilan carbone est souvent le p\u00e9rim\u00e8tre le plus complexe \u00e0 calculer pour les organisations. Dans cet article, d\u00e9couvrez comment mettre en place une collecte des donn\u00e9es efficaces ainsi que les diff\u00e9rentes m\u00e9thodes de calcul pour les \u00e9missions en amont et en aval.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Calcul des \u00e9missions du scope 3 : principes de base\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

Le scope 3 englobe toutes les \u00e9missions indirectes li\u00e9es aux activit\u00e9s d'une entreprise, mais qui se produisent \u00e0 l'ext\u00e9rieur de ses fronti\u00e8res op\u00e9rationnelles directes. La complexit\u00e9 de la m\u00e9thode de calcul du scope 3 r\u00e9sulte de la diversit\u00e9 des sources d'\u00e9mission, mais \u00e9galement des sp\u00e9cificit\u00e9s des calculs li\u00e9s aux autres organisations qui interagissent avec l\u2019entreprise concern\u00e9e.<\/p>

Avant de proc\u00e9der au calcul, il est primordial de d\u00e9finir clairement les limites op\u00e9rationnelles, afin de d\u00e9terminer pr\u00e9cis\u00e9ment ce qui sera inclus et ce qui sera exclu du p\u00e9rim\u00e8tre d'analyse. Cette d\u00e9marche garantit non seulement la coh\u00e9rence des donn\u00e9es, mais elle permet \u00e9galement d'\u00e9viter les doublons ou les omissions.<\/p>

Pour chaque categorie d'emissions du scopes 3 <\/a><\/a>, l'utilisation de facteurs d'\u00e9mission sp\u00e9cifiques est essentielle. Ces coefficients, g\u00e9n\u00e9ralement exprim\u00e9s en kg ou en tonnes de CO2 \u00e9quivalent par unit\u00e9 d'activit\u00e9, sont utilis\u00e9s pour convertir les donn\u00e9es d'activit\u00e9 en \u00e9missions de ges. Ces facteurs sont souvent issus de bases de donn\u00e9es nationales ou internationales et doivent \u00eatre r\u00e9guli\u00e8rement mis \u00e0 jour pour refl\u00e9ter les \u00e9volutions technologiques et sectorielles.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Comment collecter les donn\u00e9es pour le calcul des \u00e9missions du scope 3 ?\n<\/h2>\t\t\t\t<\/div>\n\t\t\t\t
\n\t\t\t\t\t\t\t\t\t

La collecte de donn\u00e9es constitue une \u00e9tape cl\u00e9 dans le processus de calcul des \u00e9missions du scope 3. Etant donn\u00e9 la nature indirecte de ces \u00e9missions, la r\u00e9cup\u00e9ration de donn\u00e9es pr\u00e9cises peut s'av\u00e9rer complexe. Les entreprises doivent souvent recourir \u00e0 diverses m\u00e9thodes pour recueillir les informations relatives au calcul du scope 3.<\/p>

L'une des m\u00e9thodes les plus courantes est de solliciter directement les fournisseurs pour obtenir des informations sp\u00e9cifiques sur leurs \u00e9missions. A travers des questionnaires d\u00e9taill\u00e9s, les entreprises peuvent recueillir des donn\u00e9es quantitatives et qualitatives pertinentes.<\/p>

De nombreuses industries disposent \u00e9galement de bases de donn\u00e9es sectorielles qui compilent des informations sur les \u00e9missions moyennes associ\u00e9es \u00e0 diverses activit\u00e9s ou produits. En s'appuyant sur ces ressources, les entreprises peuvent estimer leurs \u00e9missions indirectes.<\/p>

Dans certaines situations, la collecte directe de donn\u00e9es <\/a><\/a> peut s\u2019av\u00e9rer impossible ou inexacte. dans ce cas, les entreprises ont recours \u00e0 des estimations. En se basant sur des hypoth\u00e8ses raisonnables et en utilisant des donn\u00e9es existantes, elles peuvent mod\u00e9liser des sc\u00e9narios pour estimer leurs \u00e9missions du scope 3.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t

Pour calculer les \u00e9missions li\u00e9es \u00e0 l\u2019achat de biens et services, les organisations peuvent se r\u00e9f\u00e9rer aux donn\u00e9es fournies par leurs fournisseurs ou utiliser des bases de donn\u00e9es sectorielles qui indiquent les \u00e9missions moyennes associ\u00e9es \u00e0 des biens ou services sp\u00e9cifiques.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Afin d\u2019estimer les \u00e9missions li\u00e9es au transport et \u00e0 la distribution en dehors du site de l'entreprise, il est crucial de consid\u00e9rer le type de transport (camion, train, avion, etc.), la distance parcourue, ainsi que la capacit\u00e9 de charge et le taux d'occupation. Des facteurs d'\u00e9mission sp\u00e9cifiques \u00e0 chaque mode de transport peuvent \u00eatre utilis\u00e9s pour obtenir une estimation pr\u00e9cise.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Estimer l'empreinte carbone des produits pendant leur phase d'utilisation peut \u00eatre complexe. Cette estimation d\u00e9pend du type de produit, de son efficacit\u00e9 \u00e9nerg\u00e9tique, de la fr\u00e9quence d'utilisation et de la dur\u00e9e de vie du produit.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Pour les d\u00e9placements professionnels, il est essentiel de recueillir des donn\u00e9es sur la distance parcourue, le mode de transport, et la fr\u00e9quence des voyages. De m\u00eame, pour les trajets domicile-travail des employ\u00e9s, une enqu\u00eate interne peut aider \u00e0 d\u00e9terminer les moyens de transport utilis\u00e9s, les distances moyennes parcourues, et la fr\u00e9quence des d\u00e9placements.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

L'estimation de l'empreinte carbone \u00e0 la fin de la vie d'un produit n\u00e9cessite de prendre en compte plusieurs aspects, comme le nombre de produits recycl\u00e9s, r\u00e9utilis\u00e9s ou mis en d\u00e9charge. Pour ceux qui sont recycl\u00e9s, il faut estimer l'\u00e9nergie et les ressources n\u00e9cessaires pour le processus de recyclage. Pour ceux qui sont mis en d\u00e9charge, il est important de prendre en compte les \u00e9missions g\u00e9n\u00e9r\u00e9es lors de leur d\u00e9composition.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\t

L'empreinte carbone associ\u00e9e au transport et \u00e0 la distribution apr\u00e8s le point de vente est influenc\u00e9e par plusieurs facteurs, tels que le mode de transport, la distance parcourue, et la fr\u00e9quence de livraison. Des bases de donn\u00e9es sp\u00e9cifiques au secteur peuvent fournir des facteurs d'\u00e9mission par type de transport et par kilom\u00e8tre parcouru, permettant ainsi une estimation pr\u00e9cise.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t

Les \u00e9missions associ\u00e9es aux investissements peuvent provenir des activit\u00e9s des entreprises dans lesquelles l'organisation investit. Une approche courante consiste \u00e0 \u00e9valuer proportionnellement les \u00e9missions en fonction de la part de l'investissement dans l'entreprise cible.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t
