Environment

A green leader

Driven by nature
Climate change is the most significant challenge facing our generation and this urgency adds meaning to our work. For us, protecting the environment is both our passion and our job. Our employees work hard to raise environmental protection to higher levels of excellence – so we can fight the climate crisis effectively. We have installed over 107 GW of wind power globally, which powers more than 98 million European households annually and reduces CO2 emissions by more than 300 million tons per year, which is the equivalent to planting more than 4.8 million trees. Providing affordable and clean energy in accordance with Sustainable Development Goal (SDG) 7 is fundamental to our culture.

Environmental policies

Preserving the environment is one of our guiding principles. Siemens Gamesa has established several policies that outline our obligatory and voluntary commitments to protect and enhance the environment.

These policies address different aspects of environmental protection appropriate to the context of our business, including the nature, scale and environmental impacts of our operations, products and services, in addition to the interests of our stakeholders.

Our policies are regularly reviewed and apply globally, covering our entire operations. They apply to all Siemens Gamesa employees and, furthermore, are relevant to our business partners.

Powering a net-zero future

Siemens Gamesa is deeply committed to generating a positive effect on the environment, providing clean solutions to power our homes, schools, hospitals and keeping us moving wherever we are – from the largest cities to the most remote corners of the planet. To this end, the company has outlined our way to contribute a decarbonized economy, with the goal of reaching net-zero emissions by 2040. This includes emissions produced by the company’s whole value chain. Previously, the net-zero target was 2050.

Our roadmap involves six emission reduction levers:
  • Energy reduction and efficiency measures
  • Electricity supply from renewable sources
  • Green mobility and fleet plan
  • Offseting projects for non-avoidable emissions
  • Employee awareness campaigns and idea management
  • Increased engagement across the value chain

Siemens Gamesa became carbon neutral in 2019 – five years ahead of schedule. In 2020, the company became powered by 100% renewable energy and had the SBTi (Science Based Targets Initiative) verify that our emission reduction targets until 2025 are meeting the most ambitious 1.5°C scenario. To document our progress, we publish our Greenhouse Gas Emissions report annually which is externally verified according to the requirements described in ISO 14064-1:2018.

Together, our product portfolio and decarbonization strategy represents our biggest contributions to climate change mitigation according to SDG 13. Nevertheless, we work with multiple global communities who share our commitment to climate protection and decarbonization. For example, the Paris Pledge for Action, Caring for Climate and The Science Based Targets Initiative. We are also a CDP A-Lister.
Life cycle assessments

Siemens Gamesa calculates the environmental footprint of wind turbines using Life Cycle Assessments (LCA) – a method that assesses our product’s environmental impact over its entire life cycle, from raw material extraction and manufacturing, through transport, installation and operation, to decommissioning and recycling. We present the LCA results using Environmental Product Declarations (EPDs).

Our LCAs and EPDs are made in accordance with the ISO 14040, 14021 and 14025 series of standards and applicable Product Category Rules (PCRs). Many of these can be found in The International EPD® System.

Environmental criteria in product design
Apart from the clear environmental benefits of wind turbines, Siemens Gamesa designs, manufactures and services its products in ways that enhance their environmental performance. In line with SDG 12, we use a life cycle approach so that our wind turbines not only provide clean energy during operation but are also resource efficient and recyclable.

Our most significant efforts include:

  • Reducing waste, energy and water
  • Reducing and substituting materials, including chemicals
  • Optimizing packaging and logistics
  • Improving capacity factors for higher energy outputs
  • Applying remote diagnostics to increase availability
  • Adopting alternative technologies for installation and service vessels
  • Reducing service time frequencies
  • Protecting wildlife with integrated SCADA control systems
  • Offering component upgrades and spare parts to extend turbine lifetime
  • Repairing and refurbishing components
  • Designing modular components to optimize dismantling and waste treatment
  • Seeking alternative materials for high recyclability
Pioneering turbine recyclability

While it is critical to hit net-zero targets and provide affordable, clean energy to the world, the rollout of clean energy must be done in a sustainable way, actively avoiding environmental damage and supporting the circular economy with a reduced reliance on resources.

The wind industry is still relatively young and is aware of the responsibility it holds of finding a sustainable way to deal with wind turbine components at the end of their life cycle. Increasing the recyclability of the wind components is high on our agenda, and we are committed to producing 100% recyclable turbines by 2040.

RecyclableBlade – Taking responsibility. Blade by blade

Previously, the industry has not been able to recycle wind turbine blades upon decommissioning, resulting in blades ending up as landfill. Now, thanks to our pioneering RecyclableBlade technology, the materials from our RecyclableBlade can be recycled and reused in other industries to the benefit of future generations.

The RecyclableBlade is the first product to offer a comprehensive recyclable solution and is ready for commercial use offshore. These wind turbine blades can now be transformed into other applications across various industries, providing streams of recycled materials for use in different manufacturing processes. A groundbreaking step towards creating a waste-free future for the wind industry.

Our RecyclableBlade is a simple, and robust solution, developed through technological ingenuity. The only change to the blade production process is our new resin. This means that scaling up production and rolling out this recyclable product is not only possible, it is already a reality! The first blades have already been produced in 2021.
Other projects
Siemens Gamesa backs WindEurope’s call for a Europe-wide ban on landfilling turbine blades by 2025. We also advocate for industry wide international standards on product decommissioning and recycling. We are a long-standing leader in numerous industry consortia and research projects to support the development of a circular economy. Some examples of these include DecomBlades, FiberEUse and GenVind.

We focus both on finding ways to demonstrate commercial value chains for thermoset rotor blades that are already installed in our fleet as well as investigating new materials with enhanced circularity for our future blades.
Enhancing biodiversity
Siemens Gamesa is aware of its interactions, and potential impact, on terrestrial and marine natural ecosystems, habitats, and species where its factories and turbine assets are.

There are various regulatory and voluntary instruments that ensure Siemens Gamesa’s wind projects are constructed and serviced in a way that allows for co-existence, and often a net-positive biodiversity impact. This is in line with SDG 14 and SDG 15, protecting life below water and on land, respectively.

When developing a new factory or planning a new wind farm, we carry out assessments to determine potential environmental impacts. We develop adaptation and mitigation measures specific to the outcomes of these in order to minimize adverse environmental impacts according to the mitigation hierarchy, international standards, and country-specific regulation.
