    Stabilizing climate change requires simultaneous mitigation of all greenhouse gas emissions (GHGs). Here the authors examine 90 mitigation scenarios pairing different levels of CO2 and non-CO2 GHG abatement pathways to demonstrate the contributions of different GHGs towards 1.5 °C and 2 °C goals.

    Building construction causes large material-related emissions which present a serious decarbonization challenge. Here, the authors show that the building material sector could halve emissions by increasing efficiency until 2060 but even then its emissions would be twice as high as needed to meet the 1.5 °C target.

    Despite global initiatives to reach net-zero CO2 emissions, the tradeoffs of energy systems to reach that goal remain understudied. Here the authors analyze all net-zero scenarios used for the 2018 IPCC report and quantify the role of renewable energy, fuels, and emissions in attaining a zero CO2 world.

    Afforestation is an important greenhouse gas (GHG) mitigation strategy but the efficacy of commercial (harvested) forestry is disputed. Here the authors apply dynamic life cycle assessment to show that new commercial conifer forests can achieve up to 269% more GHG mitigation than semi-natural forests, over 100 years.

    China has pledged to achieve carbon neutrality in 2060. Here the authors find a promising option to abate 1.0 Gt CO2-eq yr−1 of carbon emissions at a marginal cost of $69 (t CO2-eq)−1 by retrofitting 222 GW of coal power plants to co-fire with biomass and upgrading to CCS operation across 2836 counties in China.

    Do we mitigate climate change in a Kyoto style global agreement or via multiple agreements among smaller groups of states? Here the authors show that the best strategy may begin with regional legally binding, aggressive agreements and, as these become common, renew pursuit of a global legally-binding treaty.

    The production of chlorofluorocarbons (CFC) was phased-out under the Montreal, but renewed emissions of CFC-11 have been reported recently. Here, the authors present a joint analysis of multiple factors and find that emissions of CFC-11, but also CFC-12 and CFC-113 are higher than expected, indicating renewed emissions.

    Established climate mitigation modelling relies on controversial negative emissions and unprecedented technological change, but neglects to consider degrowth scenarios. Here the authors show that degrowth scenarios minimize many key risks for feasibility and sustainability and thus need to be thoroughly assessed.

    Ambitious climate policies can negatively impact the global poor by affecting income, food and energy prices. Here, the authors quantify this effect, and show that it can be compensated by national redistribution of the carbon pricing revenues in combination with international climate finance.

    Many trajectories for reaching climate change mitigation targets exaggerate the long-term need for CO2 removal (CDR) because they assume an exponentially increasing carbon price. Here the authors analyse alternative carbon price pathways that halt warming while limiting CDR, and may be easier to implement.

    The regulation of aircraft engine NOx emissions was introduced to improve local air quality and reduce NOx emissions at altitude. Here, the authors find that greater fuel efficiency of aircrafts, and therefore lower CO2 emissions, could be preferable to reducing NOx emissions in terms of the aviation industries future climate impacts.

    Governments may struggle to impose costly polices on vital industries, resulting in a greater need for negative emissions. Here, the authors model a direct air capture crash deployment program, finding it can remove 2.3 GtCO2 yr–1 in 2050, 13–20 GtCO2 yr–1 in 2075, and 570–840 GtCO2 cumulative over 2025–2100.

    Forests are critical for stabilizing our climate, but costs of mitigation remain uncertain. Here the authors show the global forest sector could reduce emissions by 6.0 GtCO2 yr−1 in 2055, or roughly 10% of the mitigation needed to limit warming to 1.5 °C by mid-century, at a cost of 393 billion USD yr−1, or $281/tCO2.

    Extreme heat adversely affects human health, productivity, and well-being, with more frequent and intense heatwaves projected to increase exposures. However, current risk projections oversimplify critical inter-individual factors of human thermoregulation, resulting in unreliable and unrealistic estimates of future adverse health outcomes.

    Terms such as ‘climate change’ and ‘climate crisis’ need to be evaluated for their effectiveness for public perception. In this study of a sample of the Taiwanese public reactions to the terms were largely the same, however, in specific subgroups the term ‘climate crisis’ faced some backlash.

    Climate action from local actors is vital in achieving nationally determined contributions under the Paris Agreement. Here the authors show that existing commitments from U.S. states, cities and business could reduce emissions 25% below 2005 levels by 2030, with expanded subnational action reducing emissions by 37% and federal action by up to 49%.

    As low-carbon energy technologies advance, markets are driving demand for energy transition metals, increasing the stress placed on people and the environment in extractive locations. Here, the authors quantify this stress by developing a set of global composite environmental, social and governance risk indicators, and find that 84% of platinum resources and 70% of cobalt resources are located in high-risk contexts.

    In the light of nine Earth System Processes (ESPs) and the corresponding planetary boundaries, here the authors assessed the global environmental impact of a global carbon pricing in a multi-boundary world. They show that a global carbon tax would relieve pressure on most ESPs and it is therefore stronger in a multi-boundary world than when considering climate change in isolation.
