360° sustainability


Sustainability is at the core of our business model. We help our customers to save energy and water in residential and commercial buildings. The better we do this, the better our market position is. It is therefore a question of living the sustainability idea throughout the entire company in a credible way.

We are continuously improving our own use of resources, working on ever new product and service innovations and are committed to open dialogue with civil society. And we encourage our employees to show initiative outside the company as well.

Contributing to the bigger picture

With our sustainability strategy, we are also contributing to our corporate vision. With it, we want to

  • be leading in energy and water management as our products and services contribute to greater transparency, energy efficiency and therefore to a reduction in CO2 emissions.
  • partner with our customers for, as both a global and local partner, we put customer satisfaction first.
  • achieve process and technology leadership through innovation in our technologies, through internationally standard processes and through highly qualified employees.
  • create a culture of trust as the relationships with our business partners and employees are based on openness, honesty and mutual respect.

At ista, the corporate vision and sustainability strategy pursue the same goal: to make a contribution to sustainable added value.

Confirmation of our strategy

We want to continually improve our performance in the field of sustainability. In the reporting year and in preparation for this report, we therefore conducted a process to establish key subjects. The sustainability issues prioritised by external stakeholders and internal sustainability experts largely confirmed our strategic fields of action. These are: energy and resources, products and services, employees and dialogue with politicians and society (see diagram). The structure of the ista sustainability report is also based on these fields of action. We are planning further specification and differentiation of these fields of action for the coming reporting year.


ista’s sustainability strategy is based on responsibility in leadership as well as responsibility in the business model and for society.


In order to implement the sustainability strategy, we have set ourselves a strategic objective for each field of action. Our sustainability report describes what action is needed to achieve these goals and the current degree to which these targets have been attained.


Fields of action and Strategic objectives

Field of action: Energy and resources

Strategic objective: 13 % reduction in the average CO2 emissions of our company car fleet in Germany (excl. pool vehicles and vehicles of the customer service technicians)

Status 2014: Implemented in 2014, new company car regulations reduce the previous upper limits for CO2 emissions of the vehicles in the individual company car groups. New vehicles may only be chosen and leased if the ECE standard consumption is below the thresholds. Company car drivers are provided with regular information on their own consumption. The average CO2 emissions of the company car fleet were reduced by 4.8 g per km or 2.67% in 2014.

Target horizon: 2018    

Field of action: Products and services

Strategic objective: International harmonisation of the product and service portfolio to increase efficiency and reach new markets and customers with the existing portfolio.

Status 2014: A materiality analysis to determine the stakeholder interests and concerns was conducted for the first time in 2014. Decision taken to extend the materiality analysis to international locations.

Ambassadors for sustainability

Our employees are our ambassadors for greater sustainability. They implement ista’s sustainability strategy in everyday working life and communicate our values to the public through their social engagement. For it is only through respect for the environment, colleagues, customers and society that we remain an attractive employer, an internationally successful company and opinion leader in our branch of industry.

Long-term opportunities and risks

ista is affected both by the opportunities and risks of climate change because of the strong focus on energy efficiency in our core business. For products and services which conserve resources are in ever greater demand. Furthermore, politically driven climate protection involves laws and regulations which promote individual and regular consumption information. One example of this is the European Energy Efficiency Directive (EED). However, we do not gain any competitive advantages from this.

We are not experiencing any negative effects on our business from climate change. However, we may well be affected by regulatory action at our branches, for example in connection with energy-efficient refurbishment work which has to be performed on ista buildings. Against this background, ista’s management has not put a figure on the financial consequences for the company arising from climate change.
