Taking responsibility

Only people who are aware of their responsibility can assume it.

We at ista are convinced of this. Therefore, we share our knowledge to promote awareness in society for the responsible use of energy. For this reason we pass on knowledge about energy efficiency and resource conservation to as many people as possible.

Efficiency through transparency

With our data-based products and services residents and owners of buildings are well informed about their own personal enery consumption, save energy and contribute to climate protection. In Germany alone, 3.7 million tonnes of CO2 are saved every year thanks to the annual heating cost bills from ista.

In addition, we expect that a monthly consumption update would save another 1.5 million tonnes of CO2. After all, monthly checks of consumption lead to average energy savings of 10 % as the three-year pilot project 'Saving money through clever heating' of the German Energy Agency (DENA) has demonstrated.

With us, residents in buildings save energy, costs and CO2 emissions.

Our core product, data-based heat cost allocation, helps residents of multi-family buildings to save in average 20 % of their annual heat consumption and costs. Every year some 3.7 million tonnes of CO2 emissions are avoided by our customers in Germany alone.

Our Goals & Actions

We help people make their contribution to climate protection.

This guiding principle sums up our CSR strategy. For the company ista is not only committed to ecological and social action itself but would also like to empower others to take such action. To promote sustainability in a targeted manner, we are active in five fields of action:

We help people make their contribution to climate protection.
Environment Environmental protection & energy efficiency
Markets Innovative services & products
Employees Culture & working world
Partners Coorperation & exchange of views
Society Awareness & education

Sustainability begins with us. We promote environmental and climate protection in all areas of the company – for example by resource-conserving action.

Our Goals:

  • By conserving resources in all areas of the company, we will be climate-neutral by 2050.
  • We want to reduce our annual energy consumption in Germany by 6.5% from 2016 to the end of 2020. For the ista Group, we are striving to achieve a continuous improvement in energy efficiency of 1.3% on an annual average.

Innovation creates progress – our products and services make energy consumption transparent and help our users behave in a more climate-conscious way. So landlords and tenants can reduce their ecological footprint and save costs.

Our Goals:

  • We will help our customers/users reduce their CO2 emissions by 10% by 2030 (base year: 2010).
  • By 2027 we will equip all properties throughout Europe with remotely readable devices. We have already installed 25 million remotely readable end devices in our customers’ properties worldwide and almost 400,000 more are added every month.

Our employees help people live in an energy-efficient way – as employers, we create a corporate culture that supports them in achieving this.

Our Goals:

  • Engagement: We want to further improve the general conditions for employee engagement and so maintain our engagement score at the very high level of 80 in the period through to 2030.
  • Diversity is key to us: ista guarantees that employees can perform their roles in a non-discriminatory environment. ista Deutschland GmbH has voluntarily committed to filling at least 22% of managerial positions on the first and second levels below the Management Board with women by 2022.

We tackle sustainability together – we work in close cooperation with our ista service partners and suppliers in order to continuously improve our service offering and drive sustainability forward.

Our Goal:

  • From 2050, we will work exclusively with sustainable and climate-neutral suppliers as partners.

Only people who are aware of their responsibility can assume it – ista shares knowledge to promote climate protection and energy awareness in society.

Our Goal:

  • We will create opportunities for our employees to invest at least 5,000 hours a year in promoting climate protection in society.

“Only people who know what they are consuming can use energy more carefully and so save co and costs and make their own personal contribution to climate protection.”

Corporate Governance

At ista, the subject of sustainability is the direct responsibility of the Management. Our CEO is a member of the Sustainability Core Team – together with the Sustainability Office and selected Head Office departments that deal with sustainability topics on a daily basis.

The Core Team evaluates our sustainability strategy every three months and drives current topics forward. In addition, it prepares the targets and strategies for the Sustainability Steering Committee, which, as the central steering body, meets once a year to set the focal points of our sustainability management and develop the sustainability strategy further.

The Sustainability Steering Committee is made up of all members of the Management and the senior vice presidents of strategically relevant Head Office departments. The Sustainability Council is responsible for the international anchoring of sustainability management at ista and presents ideas from the countries to the Steering Committee. It is made up of members of the national organisations, the Sustainability Delegates.

Our Sustainability Office coordinates the in-house sustainability projects and processes. It is also responsible for certification of the energy management system in Germany and collecting the key figures for the sustainability report. The Sustainability Office organises the regular exchange of information between the Sustainability Steering Committee and the Sustainability Council.

It is a fundamental part of ista's culture to interact with the environment and society, with colleagues, customers and other stakeholders in a respectful and careful manner.
