Growing market demand for decarbonization / SF6-free

switching products

• Under the UNFCCC (United Nations Framework Convention on Climate Change) Paris Agreement signed by

189 countries of the world in 2015, it was agreed to limit anthropogenic global warming to well under 2º centigrade.

• Each country must determine, plan and regularly report on the contribution that it undertakes to reduce global

warming by mitigating its greenhouse-gas-emissions.

• SF6 like CO2 is a green-house gas.

• Since global carbon emissions in 2019 hit an all-time high record of 36.8 billion metric tons, the pressure on

power utilities to expedite their decarbonization efforts is increasing!

• High demand for

digitalization triggering

utilities to enhance digital

monitoring of their T&D

assets & installed base

• High public awareness of

decarbonization

• Growing demand by utilities

for independence from

OEM- specific maintenance

requirements.

• Growing demand for

maintenance-free products

which ensure lowest

operating costs and lowest

TCO*.

Growing demand for health & safety, digitalization & low TCO

• High focus by power utilities on reducing health & safety risks

caused by leakage of toxic (greenhouse) gases and their by-

products.

Growing number of companies going for SF6-free

“TenneT developed an SF6 policy, striving to minimize usage and emissions of SF6. Target is to reduce relative SF6

emissions by 20% in 2020 compared to 2015.” TenneT Germany / Netherlands (Annual Report 2014)

“Our target is to reduce our greenhouse gas emissions by 45% by 2020 and 80% by 2050 compared to 1990.”

National Grid UK (Annual Report 2014/15)

“RTE launched a proactive initiative to reduce leakage of SF6, a gas with strong greenhouse effect.”

RTE France (Annual Electricity Report 2014)

“Responsibility on Environmental Protection and Low Carbon Emission: responsible for environment.”SGCC China (Social Responsibility Report 2013)

“Building on ongoing sustainability efforts, Pacific Gas and Electric Company (PG&E) announced a new goal to

reduce 1 million tons of greenhouse-gas emissions from company operations through 2022 … Through the

company's operational plans, PG&E aims to: Make its facilities more energy efficient and sustainable.“

PG&E California / USA (External Communications – 12.07.2018)

“The large proportion of hydropower in Norway’s power system makes it the world’s most climate-friendly system.

Now we are investing in a pilot project which uses an environment friendly alternative to SF6 gas, thus becoming

the first project of its kind in the world with this technology”. BKK Nett CEO Wenche Teigland (June 2018&E California / USA)

Siemens blue high-

voltage products Philosophy & definition

Portfolio overview



For Siemens to classify a product as ‘blue’, it has to meet a series of strict criteria.

Our environmental protection and sustainability requirements are listed below.

Siemens blue high-voltage products

Philosophy & definition

No F-gases

Blue products are out of

scope of any kind of F-gas

regulation (no SF₆ or other

F-gases contained).

Zero greenhouse gas

emissions

Blue products’ have zero Global

Warming Potential (GWP).

Leading position in terms

of sustainability

Blue products give high public and

market acceptance due to greenhouse

gas-free operation, low maintenance

and simple end of life treatment

Use of environmentally

safe materials

Materials and substances meet

highest health & safety standards

(e.g. REACH, RoHS in Europe),

Long lasting design

Blue products’ operational life time

is expected to be more than 40

years - saving natural resources.

Built-in Circular Economy

Recycling studies and defined return

schemes help to qualify blue products

for recycling loops

Documentation

Blue products provide a life cycle

analysis (LCA) and environmental

declaration (Type II) acc. to ISO 14021
