Siemens is going carbon neutral

With our commitment to turn our operations carbon-neutral by 2030, Siemens set a clear signal even before the adoption of the Paris Agreement. By setting this goal, we express our firm belief that companies play a pioneering role in the fight against climate change. Our goal is clear: All Siemens production facilities and buildings worldwide are to achieve a net-zero carbon footprint by 2030. This program not only benefits humanity and the environment, but also comes with sustainable economic advantages for our company. We focus on four key levers.

CO2 reduction achievements by region

Since the launch of its carbon neutral program, Siemens has already cut CO2 emissions by over 20% globally

All countries
CO2 reductions achieved so far (as at FY2016, baseline FY2014)
  • Energy efficiency: 1 project currently in the process of implementation, savings of approx. 500,000 euros in annual energy costs
Czech Republic
  • Green power: From 2017 onwards, all sites will be powered by nearly 100% renewable energy.
  • Energy efficiency: 1 project completed, savings of approx. 300,000 euros in annual energy costs
  • Green power: 30+ manufacturing sites powered by 100 % renewable electricity
  • Energy efficiency: 2 project implemented, 2 completed; savings of over 1.5 million euros in annual energy costs
  • Decentralized power generation: Once completed, Campus Erlangen will boast a carbon footprint of zero. Siemens headquarters: A photovoltaic system supplies one-third of overall power consumed.
United Kingdom
  • Green power: All UK sites are powered by 100% renewable energy
  • Energy efficiency projects launched at sites in the state of Goa and in the city of Kalwa
  • Green power: From 2017 onwards, all sites will be powered by nearly 100% renewable energy.
  • Green power: In 2017, Sidensjö – a recently completed Siemens wind farm – will generate 370 GWh of renewable electricity.
  • Energy efficiency: 1 project currently in the process of implementation, savings of approx. 1.2 million euros in annual energy costs
  • Green power: In 2016, 2 projects in the process of implementation 50 % renewable electricity.
  • Energy efficiency: 2 projects currently in the process of implementation, savings of more than 1.6 million euros in annual energy costs

Siemens Energy Efficiency Program

A promising approach: Saving energy with Siemens technology

Siemens plans to invest some €100 million in energy efficiency projects at its production facilities and buildings by 2020. Savings in power consumption and heat generation are expected to cut carbon dioxide emissions by an annual 80,000 metric tons.


Prior to the launch of the carbon neutral program, Siemens has already implemented energy efficiency measures at 24 sites. From 2010 to 2014, this smaller-scale energy-efficiency program contributed to an increase in carbon efficiency by as much as 20%. We are now building on its success: More than 17 energy efficiency projects were kicked off last year alone, 3 of which were successfully implemented within one year and have an amortization period of 5 years or less.

Decentralized energy systems

Decentralized energy systems reduce costs

With its global market development approach, Decentralized Energy Systems (DES), Siemens aims to promote innovative solutions covering aspects of power generation at both Siemens sites – and in their immediate vicinity – and improve business potential. DES technologies includes wind farms, photovoltaic power stations, energy storage and decentralized cogeneration, i.e. combined heat and power generation. In the long term, Siemens aims to secure up to 10% of its power supply using DES solutions. The expected amortization period for investments in decentralized energy projects is generally 10 years or less. Once completed, we expect to lower emissions by up to 100,000 metric tons of carbon dioxide annually.

Smart mobility

Smart Siemens solutions in e-mobility

It takes smart solutions to make transportation more efficient, safe and environmentally friendly. Mobility is a sector, in which automation, digitization and electrification are among the more obvious emerging trends. Siemens is stepping up its commitment to electromobility and making a key contribution to the reduction of CO2 emissions in the process.


Reduction of emissions from vehicle fleet

With over 45,000 vehicles worldwide, the Siemens fleet emits 15% of the company's total carbon dioxide emissions. From 2008 to 2014, Siemens successfully reduced the average CO2 emissions in Germany by as much as 30%. This program module is expected to cut gasoline costs by some 33% and reduce the fleet’s CO2 emissions by 100,000 metric tons per year until 2025. The optimization of the vehicle fleet not only lowers its environmental impact, but also comes with financial advantages: Fleet costs are expected to drop by as much as one third. To achieve its medium-term target – reducing the average fleet emissions to 95 grams of CO2 per kilometer by 2020 – Siemens is gradually introducing appropriate directives in all countries. Attractive smart mobility offers complement the program.

Purchase of clean electricity

Green power for Siemens

Compared to other areas such as fuel consumption or district heating, power consumption causes the largest share of Siemens’ total carbon dioxide emissions. We therefore move into purchasing electricity from renewable energy sources. Our initial focus is on countries with a high demand for electricity – Germany, the USA, the Czech Republic, the United Kingdom, and Austria.


Germany: First notable successes

Operations in Germany are responsible for more than one third of Siemens’ total power consumption. Siemens therefore purchases 50% of the electricity it requires in Germany from renewable energy sources. After the switch to green electricity at 38 of its German sites, the carbon footprint of Siemens shrank by as much as 200,000 metric tons in fiscal 2016. Next year, greenhouse gas certificates from a Swedish wind farm running Siemens turbines will help to further reduce the carbon footprint of German Siemens sites. This step speaks of Siemens’ clear intention to focus on sustainable Siemens solutions when purchasing clean energy. Siemens plans to reduce its emissions worldwide by 750,000 metric tons of carbon dioxide by 2020.


USA: On track to achieve its goal

20% of all Siemens sites in the US consume electricity from renewable energy sources. Our goal is for all our US sites to use 100% clean electricity by 2020.
