Cerise (Co2 Energy Report Improvement Software Efficiency) has been launched end of 2019 and implemented in 2020/2021; the aim of the project is to provide Solvay with:
- A robust and simple reporting solution, giving a detailed view of energy consumption/expenses and CO2 emissions
- An automated solution to manage ETS (European Trading Scheme) exposition for all sites concerned in Europe (~30 registers), giving a projection of EUA (EU Allowances) balance for 10 years, to be able to decide the right time to hedge EUAs on the market

3.0 Application Feature Overview
| Reports | Definition | Prompts | BW Workbook Query | Query Technical Name |
|---|---|---|---|---|
| ECO2 - Database before CO2 conv. (Core Query) | Collect all data related to Energy from the site. Data related to energy quantity, not converted in CO2 Emission. Data sources are SAP (WP1/PF1) , including IMEP data, Cost center postings and SKF postings. We also have some manual entry for site that are not in SAP. Contains SAP data + Manual entries | Authorization scope Fiscal Year Period Plant Site

| ECO2 - SAP database after CO2 conv. (Core Query) | Energy data converted into CO2 Emission. | BW_WBK_ECO2_0002 | BW_QRY_CPECO202_0001 | |
| ECO2 - Historical data from external file incl. CO2 conv. (Core Query) | Historical data from external file, energy quantity converted in CO2. | BW_WBK_ECO2_0003 | BW_QRY_CPECO202_0002 | |
| ECO2 - Manual entries before CO2 conv. (Core Query) | Capture energy data for site that are not in SAP. The expert can input data via the transaction ZECO2. Contains only only manual entries | BW_WBK_ECO2_0004 | BW_QRY_CPECO201_0002 | |
ECO2 - DataSource for ABECO204 (Core Query) | Technical datasource from CPECO01 in order to fuel conversion process in CPECO202 | No prompt | n.a | BW_QRY_CPECO201_0000 |

4.0 Functional Specification
4.1 General Data/Calculations
| Dimension | Definition | ZECO2 BW Transaction |
|---|---|---|
| Vector | Vector is the element that conveys energy and CO2 content, including:
For reporting purposes, Vectors are grouped in a multi levels hierarchy:
| |
| Vector EPS Family | EPS Family is a Vector attribute that can be used to facilitate reconciliation with former EPS Coach tool | |
| Vector Free Grp | Free Grp is an uncontrolled field that can be populated for kind of user grouping (in combination with ProdEquipt Free Grp) | |
| CO2 ETS % Group [Vector] | CO2 ETS % Group attribute is also allocated to corresponding Vectors; it is used to calculate specific emission key figure (in combination with ProdEquipt CO2 ETS % attribute and Site ETS attribute) | |
Scope 1 Scope 2 Scope 3 [Vector] | Scope 1/2/3 Group attributes are allocated to corresponding Vectors; they are used to calculate specific emission key figures (in combination with ProdEquipt Scope 1/2/3 attributes). Scope 1 represents direct energy emission. Scope 2 represents indirect energy emission link to energy production. Scope 3.3 represents energy emission upstream (Ressources before the energy production, for exemple emission emitted by the truck to get uranium for the Power plant that produce electricity) | |
| Production Equipment | Production Equipment is a subset of a physical production Site; this is the level at which calculated energy and CO2 contents of input and output Vectors are balanced. For reporting purposes, ProdEquipts are grouped in a multi levels hierarchy:
| |
| Production Unit | A production unit is assigned to one single Site | |
GBU PRS Company code | PRS Company code and BFC GBU are needed only for non SAP Sites (otherwise they are automatically derived from SAP master data) | |
ETS Register | ETS Register is the lowest level of ETS structure; only ProdUnit belonging to an ETS Site have to be assigned to a Register | |
EPS Usage | EPS Usage is a free text that is defined as Production Unit attribute in order to facilitate reconciliation with former EPS Coach tool | |
Multi Prod. Vectors | Multi Prod. Vectors flag is an critical attribute in conversion process, used to identify equipments with more than 1 ouput Vector (see above) |
