DeltaE is a sustainable company

In order to achieve climate neutrality in Estonia by 2050, we consider it important to set an example and help our customers to operate sustainably and save energy, the natural and living environment, as well as health.

DeltaE Engineering Office implements only those solutions that lead to actual resource savings.

If we want to achieve climate neutrality by 2050, it is not practical to make investments that do not take environmental protection into account.

Sustainable development goals of United Nations

In 2015, the United Nations Summit adopted 17 sustainable development goals. All UN Member States, including Estonia, are expected to base their policy-making on the creation of national social, environmental and economic strategies until 2030.
DeltaE can contribute to achieving the following goals:

We create an environment for ourselves and our customers where happy and healthy people work.

With HVAC solutions, we have improved water quality and saved 350,000 m³ of water.

Energy efficiency is DeltaE’s focus: we have built 1.5+ MW solar power plants.

We focus on the efficiency of labor-intensive sectors with high added value.

We are engaged in the development of resource-efficient and environ-mentally safe industry in Estonia.

We help local governments to achieve resource efficiency and create a sustainable society.

We use materials in an environmentally friendly way and sort the waste generated in the office.

We help increase the knowledge of society by organizing free resource efficiency trainings.

Energy-efficient companies form a balanced ecosystem of Earth.

We cooperate with the members of The Green Tiger to improve environ-mental awareness.

In January 2021, we joined The Green Tiger organization, which aims to increase the environmental awareness of companies and lay the foundations for a balanced economy. The Green Tiger represents companies making a tiger leap towards sustainability, brings together knowledge from researchers and NGOs, and formulates policies with the public sector.

At the end of 2020, we helped the private sector to develop green investment loans that support the transition to climate neutrality and a sustainable economy. Thanks to green loans, customers can finance their environmentally friendly solutions and make their daily consumption more sustainable.

Investing in lower energy consumption, renewable energy production, and day-to-day resource efficiency will improve each company’s competitive advantage.

In october, 2021, we joined Estonian small and medium sized enterprises association (EVEA). EVEAs main purpose is to protect small and medium sized enterprises and unite their voices to protect their interests.

The role and purpose of DeltaE Engineering is to be the voice in energy efficiency and green turn topics by guiding other companies in the right direction.
