The Stability and Effectiveness of Climate Coalitions
We report results from a comparison of numerically calibrated game theoretic integrated assessment models that explore the stability and performance of international coalitions for climate change mitigation. W...

Limited emission reductions from fuel subsidy removal except in energy-exporting regions
Contrary to the hopes of policymakers, fossil fuel subsidy removal would have only a small impact on global energy demand and carbon dioxide emissions and would not increase renewable energy use by 2030.

Climate Engineering and Abatement: A ‘flat’ Relationship Under Uncertainty
The potential of climate engineering to substitute or complement abatement of greenhouse gas emissions has been increasingly debated over the last years. The scientific assessment is driven to a large extent b...

Scenarios towards limiting global mean temperature increase below 1.5 °C
The 2015 Paris Agreement calls for countries to pursue efforts to limit global-mean temperature rise to 1.5 °C. The transition pathways that can meet such a target have not, however, been extensively explored....

Energy investment needs for fulfilling the Paris Agreement and achieving the Sustainable Development Goals
Low-carbon investments are necessary for driving the energy system transformation that is called for by both the Paris Agreement and Sustainable Development Goals. Improving understanding of the scale and natu...

Residual fossil CO2 emissions in 1.5–2 °C pathways
The Paris Agreement—which is aimed at holding global warming well below 2 °C while pursuing efforts to limit it below 1.5 °C—has initiated a bottom-up process of iteratively updating nationally determined cont...

Author Correction: Energy investment needs for fulfilling the Paris Agreement and achieving the Sustainable Development Goals
In the version of ‘Supplementary Data 1’ originally published with this Article, the units for the ‘Capacity|Electricity|*’ variables in the ‘Non_Investment_Annual’ tab were incorrectly given as EJ/yr; they sh...

Interaction of consumer preferences and climate policies in the global transition to low-carbon vehicles
Burgeoning demands for mobility and private vehicle ownership undermine global efforts to reduce energy-related greenhouse gas emissions. Advanced vehicles powered by low-carbon sources of electricity or hydro...

A multi-model assessment of food security implications of climate change mitigation
Holding the global increase in temperature caused by climate change well below 2 °C above pre-industrial levels, the goal affirmed by the Paris Agreement, is a major societal challenge. Meanwhile, food securit...

Open AccessTaking stock of national climate policies to evaluate implementation of the Paris Agreement
Many countries have implemented national climate policies to accomplish pledged Nationally Determined Contributions and to contribute to the temperature objectives of the Paris Agreement on climate change. In ...

Open AccessImplications of various effort-sharing approaches for national carbon budgets and emission pathways
The bottom-up approach of the Nationally Determined Contributions (NDCs) in the Paris Agreement has led countries to self-determine their greenhouse gas (GHG) emission reduction targets. The planned ‘ratchetin...

Climate thresholds and heterogeneous regions: Implications for coalition formation
The threat of climate catastrophes has been shown to radically change optimal climate policy and prospects for international climate agreements. We characterize the strategic behavior in emissions mitigation a...

Open AccessPersistent inequality in economically optimal climate policies
Benefit-cost analyses of climate policies by integrated assessment models have generated conflicting assessments. Two critical issues affecting social welfare are regional heterogeneity and inequality. These h...

Integrated perspective on translating biophysical to economic impacts of climate change
Estimates of climate change’s economic impacts vary widely, depending on the applied methodology. This uncertainty is a barrier for policymakers seeking to quantify the benefits of mitigation. In this Perspect...

Subjective Well-Being at the Macro Level—Empirics and Future Scenarios
We estimate the impact of a large number of determinants of subjective well-being (SWB) across 143 countries, and project SWB across macro-regions for different socio-economic scenarios. We focus on the 23% of...

Land-based implications of early climate actions without global net-negative emissions
Delaying climate mitigation action and allowing a temporary overshoot of temperature targets require large-scale carbon dioxide removal (CDR) in the second half of this century that may induce adverse side eff...

Net zero-emission pathways reduce the physical and economic risks of climate change
Mitigation pathways exploring end-of-century temperature targets often entail temperature overshoot. Little is known about the additional climate risks generated by overshooting temperature. Here we assessed t...

Open AccessIncreased energy use for adaptation significantly impacts mitigation pathways
Climate adaptation actions can be energy-intensive, but how adaptation feeds back into the energy system and the environment is absent in nearly all up-to-date energy scenarios. Here we quantify the impacts of...

New damage curves and multimodel analysis suggest lower optimal temperature
Economic analyses of global climate change have been criticized for their poor representation of climate change damages. Here we develop and apply aggregate damage functions in three economic Integrated Assess...
