Utilitarian benchmarks for emissions and pledges promote equity, climate and development

Introduction

Tools are needed to benchmark carbon emissions and pledges against criteria of equity and fairness. However, standard economic approaches, which use a transparent optimization framework, ignore equity. Models that do include equity benchmarks exist, but often use opaque methodologies. Here we propose a utilitarian benchmark computed in a transparent optimization framework, which could usefully inform the equity benchmark debate. Implementing the utilitarian benchmark, which we see as ethically minimal and conceptually parsimonious, in two leading climate–economy models allows for calculation of the optimal allocation of future emissions. We compare this optimum with historical emissions and initial nationally determined contributions. Compared with cost minimization, utilitarian optimization features better outcomes for human development, equity and the climate. Peak temperature is lower under utilitarianism because it reduces the human development cost of global mitigation. Utilitarianism therefore is a promising inclusion to a set of benchmarks for future explorations of climate equity.

From fossil to low carbon: The evolution of global public energy innovation

Abstract

A review of global and national energy research, development, and demonstration (RD&D) investments between 2000 and 2018 reveals that global public energy RD&D and cleaner energy RD&D investments dramatically increased, but then plateaued after 2009. In absolute values, nuclear energy has held steady, fossil energy contracted, and clean energy RD&D quadrupled. As a percentage of overall investments, both fossil fuel and nuclear investments contracted during the period. This review compares the energy innovation priorities of the world’s largest economies using the metric of public expenditures on energy RD&D. China and India have become important global public investors in energy innovation, now among the top five globally. Priorities set by the Chinese and Indian governments will thus influence new energy technology breakthroughs in the coming years. The US and Chinese governments are now competing for first place in clean energy RD&D, depending on whether or not nuclear and cross-cutting technologies are included. India has dedicated substantial funding to indigenizing nuclear power technologies. Energy RD&D by state-owned enterprises (SOEs) in major emerging economies remains skewed toward fossil fuels and nuclear. Reforming SOE expenditures to move away from fossil fuels could have a major impact on global energy technology trajectories, making a material difference in the quest to decarbonize the energy system.

The limits of opportunism: the uneven emergence of climate institutions in India

Introduction

India’s centrality to global mitigation efforts makes it an important point of inquiry in studies of climate governance. However, we understand little of how climate change has been institutionalized in India’s decision-making processes. We capture the emergence and decline of climate institutions over three decades, showing how political conditions have shaped institutional form. The politics of opportunism has animated institutional development. It resolves the tension between India’s global leadership ambitions and a deeply entrenched, equity focused narrative frame that rejects incurring large mitigation costs. Climate institutions have therefore been layered upon existing bodies and processes to create room for the organic, bottom-up growth of policies that meet development objectives while promoting mitigation. While this structure limits polarization around climate action, it also inhibits strategic intent, particularly because strong cross-governmental institutions have been unable to take root.

Net-zero emission targets are a hollow pledge

Introduction

India needs a path that shows how a focus on opportunities for low-carbon development is more likely, in practice, to deliver emissions reductions than abstract future 2050 pledges
