The reduction of greenhouse gas emissions is based on various strategies and measures. At the global level, this involves implementing the concept of sustainable development, which is reflected in increasing resource efficiency, reducing waste production, using renewable energy sources, promoting recycling and the circular economy. Industrial companies are trying to integrate environmental aspects into their business strategies and are introducing environmental management. At national level, it is about setting and meeting specific targets for reducing greenhouse gas emissions. For example, the European Union has set a target of achieving climate neutrality by 2050 and reducing CO2 emissions by 55% by 2030. This target is legally binding. Specific measures are then implemented at national level, such as charging for greenhouse gas emissions in the form of emission allowances or a carbon tax, reducing household energy consumption, reducing car transport and reducing meat and dairy consumption. All these measures are complemented by research and innovation to find new, more efficient and greener ways of production and consumption.
