Glossary - Sustainability from A to Z

Net Zero

Net-Zero Companies on the Rise: Definition, Net-Zero Standards, Costs, and Implementation Steps. Learn how companies plan to achieve net-zero by 2050—with TeamViewer as a real-world example.

EcoVadis - ESG Rating

Learn how the EcoVadis rating works, what levels of recognition are available, and what your company can do to improve its sustainability rating.

Sustainability Officer: Role and Responsibilities

Sustainability officers define and manage ESG strategies. Learn about their responsibilities, how their role differs from that of an environmental officer, and the benefits of hiring external consultants.

GHG Protocol (Greenhouse Gas Protocol)

The GHG Protocol is the world's leading standard for greenhouse gas accounting. It serves as the foundation for the CSRD, ESRS, SBTi, and net-zero strategies.

Carbon Disclosure Project (CDP)

CDP (Carbon Disclosure Project): Definition, Questionnaire, Rating, and Benefits for Companies. Learn why CDP reporting is strategically important.

Positive Impacts (Positive Impacts) according to ESRS

Positive Impacts According to the ESRS: Definition, Examples, and New Requirements in the Revised ESRS Draft. Learn which impacts will apply in the future—and which will not.

ISO 14064 – Standard for greenhouse gas inventories

ISO 14064 is an internationally recognized standard for the quantification, reporting, and verification of greenhouse gas emissions.

Carbon Footprint (Corporate Carbon Footprint, CCF)

The carbon footprint (CCF) provides a transparent overview of a company's CO₂ emissions and serves as the basis for climate strategies, reporting, and reduction measures.

Well-to-Tank (WTT)

Well-to-Tank (WTT) encompasses all emissions generated during the extraction, processing, transportation, and supply of energy sources. This approach maps the upstream supply chain for fuels and electricity.

Tank-to-Wheel (TTW)

Tank-to-Wheel (TTW) refers to direct emissions from vehicle operation—from the energy stored in the tank to the wheel. This approach is central to mobile combustion (Scope 1).

Scope 1.02 - Mobile Incineration

Mobile Combustion tracks emissions from the combustion of fuels in vehicles and mobile machinery owned or operated by a company.

Well-to-Wheel (WTW)

"Well-to-wheel" refers to all emissions from the energy source to the vehicle's use—a standard metric in mobility studies.

Scope 1 (Direct Emissions)

Scope 1 includes all direct greenhouse gas emissions from company-owned or controlled sources—ranging from boilers and vehicle fleets to process and refrigerant losses.

Scope 2 (Indirect Emissions, Energy)

Scope 2 includes all indirect emissions from purchased energy—electricity, district heating, steam, or cooling.

Product Carbon Footprint (PCF)

The Product Carbon Footprint (PCF) quantifies a product’s greenhouse gas emissions over its entire life cycle and serves as the foundation for sustainable product strategies.

Emissions Factors - A Guide to GHG Accounting, Reporting, and Best Practices

Emission factors are the multipliers used to convert activity data—such as kWh, km, or liters—into CO₂e emissions.

Corporate Carbon Footprint (CCF)

A company’s comprehensive emissions inventory—combining Scope 1, 2, and 3 emissions. The foundation for climate targets, reporting, and operational management.

Base year for the carbon footprint

The base year for the corporate carbon footprint is the key reference point for comparing emissions and setting targets in climate management.
