Environment & Climate Change

Daniel Schrag argues that in order to reestablish the United States as a serious partner in addressing global climate change, the president must make good on the original standards of the Paris Agreement.

Professor Joseph Aldy says the incoming U.S. administration can breathe new life into global efforts against climate change, but faces daunting political and economic obstacles.

Joseph Aldy advocates for a carbon-price benchmark — which could be set initially at $50 per ton and rise over time — that would reflect the benefits of reducing the pollution causing climate change.

New York Times reporter Coral Davenport shared her thoughts on how climate policy — both domestically and internationally — may be impacted by the outcome of this month’s U.S. elections in the latest episode of “Environmental Insights: Discussions on Policy and Practice from the Harvard Environmental Economics Program."

Former White House advisor Jason Bordoff, professor and founding director of the Center on Global Energy Policy at Columbia University School of International and Public Affairs (SIPA), says the incoming Biden-Harris Administration will have the opportunity to both lift the nation out of recession and combat global climate change by crafting a thoughtful economic stimulus plan containing a significant green energy investment component.

This policy brief emphasizes that the European Green Deal's effectiveness in a post Covid-19 world will require the involvement of strategic partners, especially the US. In the context of a potential US withdrawal from the Paris Agreement and the consequential vacuum, it will be even more important to engage the US in implementing the GD. In light of divergence between the US and the EU during past climate negotiations (e.g. Kyoto, Copenhagen, and Paris), we suggest a gradual approach to US engagement with GD initiatives and objectives.

To accelerate the global transition to a low-carbon economy, all energy systems and sectors must be actively decarbonized. While hydrogen has been a staple in the energy and chemical industries for decades, renewable hydrogen is drawing increased attention today as a versatile and sustainable energy carrier with the potential to play an important piece in the carbon-free energy puzzle. Countries around the world are piloting new projects and policies, yet adopting hydrogen at scale will require innovating along the value chains; scaling technologies while significantly reducing costs; deploying enabling infrastructure; and defining appropriate national and international policies and market structures.

What are the general principles of how renewable hydrogen may reshape the structure of global energy markets? What are the likely geopolitical consequences such changes would cause? A deeper understanding of these nascent dynamics will allow policy makers and corporate investors to better navigate the challenges and maximize the opportunities that decarbonization will bring, without falling into the inefficient behaviors of the past.

Growing concern around climate change has ignited recent interest in carbon capture, utilization, and storage (CCUS) technologies and generated a series of studies on its global market potential.

For decades, Singapore has been a premier refinery hub and gatekeeper between Asia and the Middle East, but its position is increasingly threatened as producer countries are shifting into the downstream activities that helped make Singapore the “Houston of Asia”. Oil and petrochemicals drive about one quarter of Singapore’s net exports. Greater competition in the global oil and gas value chain could take a heavy toll on the city-state’s national budget and economic growth prospects.

The Tesla Semi is a battery powered electric long haul truck currently in the prototype phase. Since cost and technological barriers have prevented electric vehicles from making significant inroads into the market for long haul trucks, the announcement of the Tesla Semi marks one of the first major attempts to bring electrification to on-road long haul freight transport. China, as the world’s largest carbon emitter, is an important market for truck electrification. China has a bourgeoning passenger electric vehicle market but, like the rest of the world, is reliant on heavily polluting diesel trucks for on-road freight transport. 

This paper addresses two main questions:

1. What are the potential impacts on carbon emissions of electric long haul trucks in China? 
2. What are the barriers to the adoption of electric long haul trucks in China?
