Success Story: O2 Telefónica

In order to gain important insights for decarbonisation in Scope 3, O2 Telefónica used THE CLIMATE CHOICE software platform to collect climate-focused data from selected suppliers as part of a pilot project.

Project Overview

1. Analysis

With the help of its software platform, THE CLIMATE CHOICE collected climate-relevant data from selected suppliers of O2 Telefónica as part of a pilot project.

2. Engagement

Suppliers received reporting, key benchmarks and analyses on their climate potential and strengths.

3. Decarbonisation

The comparable primary data collected in this way serves as a basis for O2 Telefónica to implement effective CO2 reduction measures in close cooperation with its suppliers.

About the company

O2 Telefónica provides telecommunication services to consumers and businesses, as well as innovative digital products and services in the fields of IoT and data analytics. The company is one of the leading integrated telecommunication providers in Germany.

Goals of O2 Telefónica

O2 Telefónica aims to be net CO2 neutral by 2025 at the latest. The company has already reduced the direct CO2 emissions in Scope 1, and indirect emis- sions by 97% in Scope 2 through electricity purchases since 2015. Now, they aim to discover climate-related risks and find potential solutions together with their suppliers. This is the basis on which O2 Telefónica also aspires to be emission-free along the supply chain by 2040 at the latest.

Climate Ready Supply Chain


O2 Telefónica was able to use THE CLIMATE CHOICE software tool to develop a transparent, scalable process for collecting comparable data on the climate maturity of selected suppliers.

The pilot project successfully identified climate-related risks and potentials of the selected suppliers.

On average, this has shown that:

  • The dimension of climate management (governance & leadership, climate responsibility, environmental management, risk and supply chain management) is already the most pronounced.
  • The greatest potential still exists in the dimension of climate impact (CO2 balance of company and product, emission reduction targets, monitoring of environmental impact).

Next Steps

In the next step, the software platform of THE CLIMATE CHOICE will be integrated into the procurement dashboard of O2 Telefónica and the climate-relevant data collection will be extended to around 1,000 suppliers.


Further on the Climate Data Platform


The CLIMATE Data Platform is a combination of climate-focused ESG rating methodology and intelligent platform technology.


The software tool provides validated data on suppliers‘ holistic climate maturity across key impact and risk dimensions: Governance, Strategy, Metrics and KPIs.


The climate scores are entered into the data platform and can be used to collaborate with business partners on decarbonisation strategies and to achieve transparent reporting and efficient climate management.
