Updated nationally determined contributions collectively raise ambition levels but need strengthening further to keep Paris goals within reach
By January 2022, 156 countries had submitted new or updated nationally determined contributions (NDCs) under the Paris Agreement. This study analyses the greenhouse gas (GHG) emissions and…
Coherence present. Navigating towards a sustainable future
The world is looking for ways to navigate challenges, such as climate change mitigation and adaptation, food security and biodiversity loss, in order to safeguard current and future global well-being…
Uncertain effectiveness of Miscanthus bioenergy expansion for climate change mitigation explored using land surface, agronomic and integrated assessment models
Large-scale bioenergy plays a key role in climate change mitigation scenarios, but its efficacy is uncertain. This study aims to quantify that uncertainty by contrasting the results of three different…
Targeted Green Recovery Measures in a Post-COVID-19 World Enable the Energy Transition
Despite the significant volume of fiscal recovery measures announced by countries to deal with the COVID-19 crisis, most recovery plans allocate a low percentage to green recovery. We present…
The impact of COVID-19 and recovery packages on emission pathways to 2030: Inputs to the UNEP Emissions Gap Report 2021 Final project report
Globally, the opportunity to use COVID-19 fiscal rescue and recovery spending to accelerate the low-carbon transition has largely been missed so far: the share of low-carbon fiscal spending ranges…
How do we take stock of the state and changing trend of the world’s environment and draw lessons from policy experiences? Amongst the myriad detailed narratives about the condition of the planet, the…
Trends in Global CO2 and Total Greenhouse Gas Emissions; 2021 Summary Report
In 2019, the growth in global greenhouse gas (GHG) emissions (excluding those from land-use change) slowed down to 0.6%, reaching 51.7 gigatonnes of CO 2 equivalent (GtCO 2 eq. This revised growth…
Developing scenarios in the context of the Paris Agreement and application in the integrated assessment model IMAGE: A framework for bridging the policy-modelling divide
The framework presented in this study aims to provide insights into how climate policy is represented in integrated assessment models, responding to the call to link model scenarios with concepts used…
Addressing international impacts of the Dutch circular economy transition
The Netherlands has the ambition to achieve a fully circular economy by 2050. This policy brief discusses the risks and opportunities of the Dutch circular economy transition for low- and middle…
Using large ensembles of climate change mitigation scenarios for robust insights
As they gain new users, climate change mitigation scenarios are playing an increasing role in transitions to net zero. One promising practice is the analysis of scenario ensembles. Here we argue that…
