Environment & Climate Change

Joel Clement writes that because the Biden administration  has moved to repair the damage done by the Trump administration, colleagues from around the global Arctic are optimistic once again about partnering with America on solutions to regional crises .

Durability and inexpensiveness—two of plastic’s greatest assets—have made it the workhorse material of modern society. But they have also become its greatest curse by creating a global environmental and sustainability crisis.

This study provides a whole-systems simulation on how to halve global CO2 emissions by 2050, compared to 2010, with an emphasis on technologies and costs, in order to avoid a dangerous increase in the global mean surface temperature by end the of this century.

The ongoing COVID-19 pandemic is upending our lives and the global economy in ways unimaginable until recently. While the overall impacts are still difficult to quantify, ramifications are sure to be felt for decades to come. Providing secure, reliable, and affordable resources for all without causing devastating environmental consequences is perhaps the greatest challenge of the 21st century. But the pandemic has significantly altered dynamics and changed priorities. How is this impacting the quest for sustainability?

In this paper we analyze these challenges by focusing on the plastic industry. There is no doubt that plastic has molded society in many ways that make our lives easier and safer, but it has also created a global environmental and sustainability crisis. In order to curb our addiction to plastic, the world had been waging a war against virgin plastic, but the pandemic has turned an enemy into a much-needed ally. How can we leverage the advantages of plastic without contributing to the world’s environmental crisis? This dilemma poses a significant challenge, but also opens an opportunity to address sustainability at a systemic level through circularity and the transition to low-carbon alternatives to petroleum-based plastics.

Harvard University has created a Presidential Committee on Sustainability (PCS) to advise President Larry Bacow and the University's leadership on sustainability vision, goals, strategy, and partnerships. The Harvard Gazette spoke with committee chairs Rebecca Henderson, the John and Natty McArthur University Professor; John Holdren, the Teresa and John Heinz Professor of Environmental Policy at Harvard Kennedy School; and Katie Lapp, executive vice president, about why it is so important to act now; the role of the PCS in developing collaborative and innovative projects; and how the campus community can get involved.

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.

The Policy and Action on Plastic in the Arctic Ocean workshop was held at the Harvard Kennedy School on 30–31 October 2019. The speakers' bios and presentations are now available.

The Arctic Transformation and Resilience Study Group, led by Arctic Initiative Senior Fellow Joel Clement, will give students the opportunity to learn about and work on issues of Arctic resilience. Working together to deliver a compilation and brief analysis of existing policies that support or inhibit resilience in the Arctic, students will have the opportunity to meet with top Arctic scientists, policymakers, indigenous knowledge-holders, and finance experts, while developing a report that will be delivered to the Secretariat of the Arctic Council Sustainable Development Working Group.

This study group will be held on Tuesdays, from 6pm–7:30pm, beginning Oct 29, and including Nov 5, 12, 19, and 26. For more information or to sign-up, please contact brittany_janis@hks.harvard.edu. Space is limited; please register by October 21.
