Navigating the black box of fair national emissions targets
Current national emissions targets fall short of the Paris Agreement goals, prompting the need for equitable ways to close this gap. Fair emissions allowances rely on effort-sharing formulas based on…
Analysis of cost-effective reduction pathways for major emitting countries to achieve the Paris Agreement climate goal
Achieving the global climate goal of the Paris Agreement depends on collective action by individual countries, as reflected in the Nationally Determined Contributions (NDCs). To inform the next NDCs…
Demand-side strategies enable rapid and deep cuts in buildings and transport emissions to 2050
Decarbonization of energy-using sectors is essential for tackling climate change. We use an ensemble of global integrated assessment models to assess CO 2 emissions reduction potentials in buildings…
Electricity- and hydrogen-driven energy system sector-coupling in net-zero CO2 emission pathways
Electricity- and hydrogen-based sector coupling contributes to realizing the transition towards greenhouse gas neutrality in the European energy system. Energy system and integrated assessment models…
Uncertainties around net-zero climate targets have major impact on emissions and climate projections
Globally, more than 100 countries have adopted net-zero targets. Most studies agree on how this increases the chance of keeping end-of-century global warming below 2°C. However, they typically make…
Extended producer responsibility for energy transition technologies
Solar panels, wind turbines and electric vehicle batteries are at the core of the energy transition. However, the rapid market growth of these products poses new challenges for the management of…
The bridge to net zero matters more than the destination
Countries have started setting their own national net-zero targets. While net-zero targets establish long-term ambitions, countries’ mid-term targets, as outlined in their Nationally Determined…
Policy mixes for sustainable development pathways: representation in integrated assessment models
The Paris Agreement on climate change and the 2030 Agenda on Sustainable Development require unprecedented transformations to sustainability, while maximising synergies and minimising trade-offs…
Quantifying food security and mitigation risks consequential to climate change impacts on crop yields
Climate change is expected to impact crop yields globally, with some regions benefiting from favorable conditions and CO 2 fertilization, while others face adverse effects from altered precipitation…
How the Russian–Ukrainian war reshapes the climate policy context
The Russian military aggression against Ukraine has had significant global impacts on energy security, economy and geopolitics. The 2022 global energy crisis raises questions about how the war affects…
