Evaluating the Climate Performance Capacity of Start-ups

The importance of early-stage VC investment for climate action is often underestimated.

The importance of early-stage VC investment for climate action is often underestimated. In the field of climate technology investment, it is essential to identify start-ups and business models that contribute to climate protection. Assessing a start-up's Climate Performance Potential can refine investment decisions for both start-ups and VCs. This…

Life-LCA: Impacts of a German Human Being in the Old Adulthood Stage

 

Life-LCA studies, which assess the environmental impacts of human beings, focused so far on the span from conception to 50 years. This case study extends the analysis to an “old adulthood stage”, including a retirement (65–75 years) and end-of-life phase (75–80 years), thus…

On the potential of temporally resolved GHG emission factors for load shifting: A case study on electrified steam generation

The integration and efficient utilization of fluctuating renewable energies are crucial for the decarbonization of

energy systems.

The integration and efficient utilization of fluctuating renewable energies are crucial for the decarbonization of
energy systems. The flexibilization of industrial processes can play a key role in achieving this objective. Previous
research mainly focusses on price-based demand side management. However, recent research shows that electricity

Developing decarbonisation targets and pathways for the example of the automotive industry

Carbon budgets are the basis for climate models and decarbonization scenarios to determine reduction targets for sectoral developments aimed at limiting global warming.

Carbon budgets are the basis for climate models and decarbonization scenarios to determine reduction targets for sectoral developments aimed at limiting global warming.

This paper proposes an allocation scheme that combines CO2eq accounting frameworks to link sectoral carbon budgets to stages of product life cycles and therefore aligns corporate…

Electricity accounting in life cycle assessment: the challenge of double counting

In grid electricity consumption models, the location-based method uses regional average emission factors to account for environmental impacts.

In grid electricity consumption models, the location-based method uses regional average emission factors to account for environmental impacts. The market-based method is based on contractual agreements, verifying the exclusive claim on electricity from specific energy sources. An inconsistent application of these methods in life cycle assessment…

Analysis of the Science Based Targets Initiative (SBTi) method and a comparison with the German Climate Protection Act

In the face of increasingly evident climate change, companies are stepping up their efforts to reduce greenhouse gas emissions.

In the face of increasingly evident climate change, companies are stepping up their efforts to reduce greenhouse gas emissions.

The Science Based Targets (SBTi) initiative offers two methods for companies to align voluntary emission reduction targets with the climate goals of the Paris Agreement.

The study examines how the interaction of the two…

A comparative assessment of value chain criticality of lithium-ion battery cells

This study assesses the criticality of material value chains for lithium-ion battery (LIB) development using the ESSENZ method.

This study assesses the criticality of material value chains for lithium-ion battery (LIB) development using the ESSENZ method.

It finds that cobalt, lithium, nickel, and graphite are critical materials in at least 36% of LIBs and account for over 85% of their overall criticality score.

Potential measures to mitigate these concerns include the…

Life cycle assessment of the environmental impacts of an infant

A new case study collected primary data on a pregnant mother, a newborn baby, and a three-year-old infant in Germany.

Life cycle assessment of the environmental impacts of an infant

A new case study collected primary data on a pregnant mother, a newborn baby, and a three-year-old infant in Germany. The study aimed to investigate the environmental impacts from ovulation to the third year of life to derive measures for reduction, show the impacts of alternative…

Compensation of a broad set of environmental impacts beyond climate change

The “Circular Ecosystem Compensation” approach is presented in a new publication.

The “Circular Ecosystem Compensation” approach is presented in a new publication. Through using the methods “Life Cycle Assessment”, “Monetization” and “Renaturation”, the compensation of environmental impacts beyond climate change is enabled. Different environmental burdens are thus compensated through environmental gains on a monetary basis. Die…

Life Cycle Assessment of Power-to-Liquid Kerosene Produced from Renewable Energy and CO2 from the Air in Germany

The publication analyses the environmental impacts of power-to-liquid kerosene using life cycle assessment.

The publication analyses the environmental impacts of power-to-liquid kerosene using life cycle assessment. Not all analysed production layouts lead to a reduction of the environmental impact. If the production is based on high-temperature electrolysis combined with low-temperature CO2 air capture and onshore wind power, the environmental impacts…

Analysis of the EU climate ambitions for greenhouse gas reductions and renewable energy consumption shares

To achieve the climate goals of the Paris Agreement, greenhouse gas emissions must be reduced and renewable energy implemented in the EU.

The publication analyzes these factors and concludes that the EU's annual reduction in greenhouse gases must be tripled by 2030 to meet the targets set. For renewable energy, the growth rate must be increased by 2% per year until 2030.
