Can We Achieve 100 Million Plug-In Electric Cars by 2030?

By Lew Fulton | https://itspeople.ucdavis.edu/staff-member/fulton-lewis-m/ | August 25, 2016

Sometime last fall, we reached a global milestone: 1 million electric light-duty vehicles or LDVs (cars and SUVs) sold since 2011. This was an incredible achievement for a zero emission technology that had seen total sales of only a few thousand before that. And yet, it is a drop in the bucket—0.1% to be precise—when compared to the growing juggernaut of 1 billion+ LDVs on the world’s roads, the great majority of them gasoline-powered.

Sales are on the upswing globally but how do we maintain 35% annual growth rates to reach 2030 goals?

What happens when demand for oil peaks?

By Jeroen van der Veer | |Amy Jaffe| https://itspeople.ucdavis.edu/staff-member/jaffe-amy-myers/ | April 15, 2016

Since the First Industrial Revolution, oil and gas have played a pivotal role in economic transformation and mobility. But now, with the prospects that major economies like the United States, China and European nations will try to shift away from oil, producers are coming to realize that their oil reserves under the ground – sometimes referred to as “black gold” – could become less valuable in the future than they are today.

The Emerging Role of California’s Natural Landscapes in Combatting Climate Change

By Kit Batten | https://itspeople.ucdavis.edu/staff-member/batten-kit/ | March 14, 2016

On March 10, The Nature Conservancy (TNC) and the UC Davis Policy Institute for Energy, Environment and the Economy co-sponsored “Natural Climate Solutions Symposium” in Sacramento which featured speakers from government, academia, non-governmental organizations, and the private sector to elevate the dialogue on how California’s natural landscapes can be used to reduce greenhouse gas emissions and help the State of California adapt to its changing climate. The event featured speakers from government, academia, non-governmental organizations, and the private sector.

Paris Climate Accord: A Strong Call to Action, Including Transportation

By Lew Fulton|https://itspeople.ucdavis.edu/staff-member/fulton-lewis-m/ | December 15, 2015

The Paris Climate Accord reached on Saturday, December 12, feels like a home run. Nearly 200 countries fully agreed on text in which they pledge to make large reductions in greenhouse gas emissions over the next 15 years, with mechanisms to help ensure that this goal is achieved. It includes quantified CO2 mitigation commitments from all major economies around the world; mechanisms for reporting and verifying progress; commitments for $100 billion in financing of actions; and many other key elements.
