2015 verursachte jeder Deutsche 628 Kilogramm Siedlungsabfall. Damit liegt Deutschland für viele Abfallströme und insbesondere für Verpackungsabfälle deutlich über dem EU-Durchschnitt. Selbst wenn die Recyclingquoten hoch ausfallen, hat die Abfallvermeidung nicht nur eine ökologische Notwendigkeit. Auch aus ökonomischer Sicht muss sie zum Ausgangspunkt einer transformativen Innovationsagenda werden.
In the Paris Agreement, the governments of the world have pledged to attain climate neutrality in the second half of this century. More precisely, in Art. 4.1 parties agreed to "achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases". However, the collective as well as the majority of measures by individual countries fall short of embarking on a pathway towards that objective. But nevertheless, an increasing number of actors - countries, sub-national entities, as well as corporations - have stepped up their efforts and set themselves carbon neutrality goals.
In this Policy Brief Lukas Hermwille and Markus Gornik portray the commitments of Costa Rica, Norway, Sweden, the City of Melbourne, Australia and the corporation Microsoft. All cases have set themselves ambitious neutrality goals and have implemented measures to achieve them. However, none of the cases will be able to achieve accomplish neutrality on their own, at least not on short-term. The remaining emissions will be compensated using carbon credits either from domestic offset schemes (Costa Rica) or from international schemes.
For the time being, voluntary carbon neutrality goals, as presented in this Policy Brief, are an effective way to demonstrate leadership in climate protection. For the near future, pioneering actors that set voluntary carbon or climate neutrality goals could provide a significant source of demand for international carbon credits.
Concretely defined targets are guiding policy efforts and the measures required to achieve national energy and low-carbon transformations in order to reach the maximum 2 degree climate change mitigation target agreed at the COP in Paris in 2015. Reducing energy consumption by harnessing the potential of energy efficiency, expanding the use of renewable energy resources, and transforming all sectors into low-energy and low-carbon structures is crucial. Among the G20 states, most states have set targets for renewable energies, energy efficiency, and greenhouse gas (GHG) emission reductions. Yet, it seems that starting points and target units differ a lot between the G20, and hence comparability is difficult. This topical paper presents a synopsis on the current targets within the G20. The relative lack of energy efficiency targets shows that this pillar needs much greater efforts in current and future energy policy.
