Based on a life-cycle sustainability assessment and the calculation of carbon abatement costs, we quantify the greenhouse-gas emission reductions and costs if green waste in the metropolitan region of Berlin, Germany, is diverted from composting into the production of hydrothermally carbonized...

Methane is a major anthropogenic greenhouse gas, second only to carbon dioxide (CO2) in its impact on climate change. Methane (CH4) has a high global warming potential that is 25 times as large as the one of CO2 on a 100 year time horizon according to the latest IPCC report. Thus, CH4...

Most climate and energy scenarios created by international organizations and researchers include a considerable expansion of nuclear energy. In the IPCC Sixth Assessment Report, for example, nuclear energy increases from a current 3,000 terawatt hours on average to over 6,000 terawatt hours in...

To achieve climate targets, efforts need to be made in Europe to improve energy efficiency and to expand renewable energies. Conditions for investing in renewable energies in Europe must be improved, subsidies for fossil and nuclear energy reduced. A 100 percent renewable energy system is...
