GHG (Greenhouse Gas Protocol): The Greenhouse Gas Protocol is an internationally recognized standard for the recording and management of greenhouse gas emissions. It provides a framework and guidelines for companies and governments to systematically measure and report their emissions. This standard helps to identify sources of emissions, promotes transparency in reporting and supports efforts to reduce greenhouse gas emissions in the fight against climate change.
Greenwashing: Greenwashing is a practice in which companies make misleading or exaggerated claims about their environmental friendliness or sustainability in order to create a positive image without actually taking substantial measures for environmental protection or social responsibility. This can be done through false advertising, unverifiable claims or the deliberate concealment of environmental impacts.

It stipulates that companies must analyze risks, take preventive measures and submit regular reports on their supply chain activities.
Net zero: Net zero refers to the state in which the greenhouse gases emitted by a given source are fully offset by emission reductions or compensation measures, leaving no net greenhouse gas emissions. This goal is crucial in the fight against climate change and is often pursued by governments, companies and organizations. To achieve net zero, emissions must be drastically reduced and remaining emissions offset through measures such as reforestation or carbon sequestration. Net zero is a key element of the Paris Agreement, which aims to limit global warming to below 2 degrees Celsius.
NFRD (Non-Financial Reporting Directive): The NFRD is an EU directive on non-financial reporting by companies. It obliges large companies with more than 500 employees to disclose information on environmental, social and employee matters, respect for human rights and the fight against corruption and bribery.

It is an important approach to promoting sustainable production and consumption practices.
SBTi (Science Based Targets Initiative): The SBTi is an initiative launched by various organizations that supports companies in setting science-based climate targets. These targets are aimed at limiting the global temperature increase to below 2 degrees Celsius compared to pre-industrial times, as set out in the Paris Agreement. The SBTi provides companies with scientific criteria and methods to ensure that their emission reduction targets are compatible with the current climate targets. By implementing science-based targets, companies can contribute to reducing greenhouse gas emissions while achieving long-term sustainability goals.
