Ely Sandler and Daniel Schrag propose a new approach to Article 6 of the Paris agreement, arguing that states must use cross-border investment to finance the energy transition. By linking additionality to an investment’s impact on cost of capital, Sandler and Schrag demonstrate how Article 6 can leverage blended finance to de-risk private investment, creating a new model of public private partnership. The paper uses case studies from the Middle East and North Africa region to demonstrate the potential economic, environmental and political benefits of cooperation on Article 6.  

John Holdren spoke to The Harvard Gazette about the proposed Inflation Reduction Act legislation and its potential impact, should it survive House scrutiny and be signed by President Biden.

On April 11, 2022, The New York Times covered the launch of the new Permafrost Pathways project, a collaboration between the Belfer Center's Arctic Initiative, Woodwell Climate Research Center, and the Alaskan Institute for Justice. The six-year effort by climate scientists and policy experts aims to fill gaps in knowledge about planet-warming emissions and help affected communities in Alaska.

Professors David Keith and Joseph Aldy and their co-authors say deeper social science research could contribute to policy decisions on this tool to address climate change.

There is an urgent need to incorporate the latest science on carbon emissions from permafrost thaw and northern wildfires into international consideration of how much more aggressively societal emissions must be reduced to address the global climate crisis.

The Arctic of today does not resemble the Arctic of fifty years ago, and the Arctic of 2070 will be different still, based on everything we know now. Warmer temperatures on land and in the ocean, retreating sea ice and glaciers, thawing permafrost, rapidly changing ecosystems, range expansion of novel species and stress in native species, changing ocean chemistry, and altered seasons all contribute to significant alteration of a region in an extremely compressed timescale. At the same time, globalization and the increasing international interest in the region add new pressures for access, development and geopolitical positioning in the Arctic. Concerns about the implications and impacts of that intensified engagement generate even more anxiety about the transformation to a brand-new Arctic in the 21st Century.

In this report, the authors conduct a benchmarking analysis for energy and CO2 emissions intensity of the steel industry among the largest steel-producing countries.

Over the past decade, the Arctic has warmed by 0.75°C, far outpacing the global average, while Antarctic temperatures have remained comparatively stable. As Earth approaches 2°C warming, the Arctic and Antarctic may reach 4°C and 2°C mean annual warming, and 7°C and 3°C winter warming, respectively. Expected consequences of increased Arctic warming include ongoing loss of land and sea ice, threats to wildlife and traditional human livelihoods, increased methane emissions, and extreme weather at lower latitudes.

Cement production is one of the most energy-intensive and highest carbon dioxide (CO2) emitting manufacturing processes. The goal of this study is to develop a roadmap for decarbonization of California's cement and concrete production. In this study, the authors look at the current status of cement and concrete production in California and develop scenarios up to 2040 to analyze different decarbonization levers that can help to reduce CO2 emissions of cement and concrete production in California.

As the United States boycotts the New York climate summit, John Holdren explains why a change in leadership is needed to restore U.S.-China climate cooperation.
