CIRCULAR ECONOMY REBOUND

Circular economy isn't a magical fix for our environmental woes

Solving our ecological crises means diluting the power of global corporations – not propping them up

 

With his former PhD student, Trevor Zink, Roland Geyer coauthored a paper that was awarded 2017 Journal of Industrial Ecology Best Paper

The work, Circular economy rebound published in the Journal of Industrial Ecology, was praised for its original content, engaging writing and excellent figures. The authors use conceptual ideas, literature review and two simple, but elegant, equations to demonstrate an important rebound effect affecting the efficacy of the circular economy.

 

Trevor Zink and Roland Geyer coauthor an impactful article challenging
the notion that sustainability means selling and buying “green” products

 

“Roland Geyer of the University of California, Santa Barbara, and Trevor Zink of Loyola Marymount University argue that comparing products to some arbitrary “benchmark” in order to determine whether or not they’re eco-friendly is causing us to not only lose sight of what eco-friendly really means, but also — in some cases — to support products that actually have an overall negative impact on the environment.”

Is There Really Such a Thing as a Green Product? A new article by University of California-Santa Barbara professor Roland Geyer and Loyola Marymount University professor Trevor Zink explores this issue in depth. Geyer is a professor of industrial ecology and green supply chain management, while Zink is a professor of sustainability and corporate social responsibility.”

Is solar power a more efficient automotive fuel than biofuels? Geyer et al. 2013 conducted a spatially explicit LCA to find the best way of harvesting sunlight

 

“Spatially explicit life cycle assessment of 5 sun-to-wheels pathways finds photovoltaic electricity and BEVs offer land-efficient and low-carbon transportation”

"What it says to me is that by continuing to throw money at biofuels, we're barking up the wrong tree," Geyer explains. "That's because of a fundamental constraint, which is the relative inefficiency of photosynthesis. And we can't say that right now, biofuels aren't so great but they'll be better in five years. That fundamental problem for biofuels will not go away, while solar EVs will just continue to get more efficient and cheaper. If they're already looking better than biofuels, in five years the gap will be even greater. A search for a silver bullet is under way through "synthetic photosynthesis," but using genetic engineering to improve the efficiency of photosynthesis is a pipe dream. If there is a silver bullet in energy, I think it's solar power."
