Climate-change policy

Climate-change policy encompasses policies formulated specifically to tackle climate change and can be local, national or international in scope. These broadly fall into two categories; those designed to minimise the extent of climate change – climate change mitigation – and those intended to minimise risks and seize upon new opportunities – climate change adaptation.

    Urgent action is needed to ensure food security and mitigate climate change. Through a multi-model comparison exercise, this study shows the potential negative trade-offs between food security and climate change mitigation if mitigation policies are carelessly designed.

    Behavioural interventions aimed at curbing carbon emissions are inexpensive and easy to implement but can offer the false promise of a quick fix. Across six experiments, the authors show that exposure to a green energy nudge diminishes support for carbon taxes.

    Aerosol impacts have not been comprehensively considered in the cost-benefit integrated assessment models that are widely used to analyze climate policy. Here the authors account for these impacts and find that the health co-benefits from improved air quality outweigh the co-harms from increased near-term warming, and that optimal climate policy results in immediate net benefits globally.

    Cities around the world are at the forefront of enacting climate mitigation policies, but effective action requires a better understanding of potential solutions. This Review offers a systematic exploration of the urban case study literature and discusses ways to best make use of the growing body of cases.

    The IPBES global assessment has brought biodiversity prominently to the attention of policymakers and the public, and researchers should seize this critical opportunity to engender change towards sustainability.

    ‘Nudge’ interventions, such as green energy defaults, may be simple and cost-effective ways to address climate change and can complement more substantive climate policies. But, new research finds that information about a nudge policy lowers support for a carbon tax, unless that nudge policy is described as part of a comprehensive approach.

    The students striking for action on climate change admirably display civic engagement on a pressing issue. Nevertheless, their movement’s message focuses far too heavily on the need to ‘listen to science’, which is at most a point of departure for answering the ethical and political questions central to climate action.

    Recent publications have raised concerns regarding the actual feasibility Negative Emission Technologies (NETs). Here the authors commented on the financial viability of large-scale late century NETs and suggested that expenditure peak will occur in the end of the century, which would require massive global subsidy program.

    Men and women differ in their perceptions of environmental risk, vulnerability to climate change impacts and adaptation behaviour. Effective policies must address the diversity of gender roles and identities, and the underlying drivers of inequality.
