Forests’ potential for climate change mitigation: Buildings as a global carbon sink

by Christopher Reyer (PIK)

How can forests and their products and services best contribute to climate change mitigation? This is probably the most controversial question one can currently ask when discussing the role of forests to combat climate change – and even scientists tend to disagree here. Some say we should manage our forest and use wood for construction to create a long-term carbon sink. Or produce even more wood to replace plastics and fossil-based materials, which is called circular bioeconomy. Others suggest just the opposite: we should not manage our forests – or if we do, we should not concentrate on wood production but mainly focus on our forests’ potential for biodiversity conservation and carbon sequestration.

All approaches have benefits and trade-offs, considering that our natural resources, including our forests, are limited. That being sad, I would like to focus in this article on the potential of using wood and wood-based products for construction to mitigate climate change, based on a paper on Buildings as a global carbon sink that we – a multidisciplinary group of researchers from Potsdam Institute for Climate Impact Research (PIK) and from Yale University – have published 2020 in Nature Sustainability. When looking at global developments, including discussions at the COP in Glasgow, results from the paper are still very valid – and further scientific and practical exploration is needed, since the world’s population is increasing, and climate change mitigation efforts will be challenged by people’s need for shelter.

Marteloscopes and Carbon – a missing piece of the puzzle?

Witten by Huntley Brownell and Andrew Stratton

Many readers of this blog are likely familiar with marteloscopes (if not, click here to read more). We think our story demonstrates the remarkable educational potential of this tool, and we would like to share it with you.

Our story begins deep in the Black Forest, outside of Freiburg in Germany. It was long, long ago, before corona times: the autumn of 2018. We were part of a group of MSc students studying Forest and Nature Management on a study tour from the University of Copenhagen, and we were brought to visit the Rosskopf marteloscope.

By now we all understand the limitations of virtual meetings; back then the forty of us, carefree and not at all socially distanced, took for granted the vibrant educational environment of in-person learning. With tablets in hand, groups of students and professors explored the marteloscope, observing, discussing, debating – sometimes passionately – the harvesting trade-offs we were considering in the exercise. Questions arose: how will our decisions affect stand biodiversity? How will the stand develop in the future if we harvest certain trees now? Are some microhabitats more important than others? What is biodiversity anyway? How much is that tree worth?

EFI looks at lowering its own carbon footprint

Limiting global warming to 1.5°C requires societies to simultaneously work on land-based mitigation options and reduce emissions in other sectors. This means approximately 45% reduction in CO2 emissions from 2010 levels by 2030. As an environmental management trainee at EFI, my task is to look at the environmental impacts of our own work and our daily operations.

In terms of climate change mitigation, the most important categories for EFI are most likely procurement of goods and services, energy consumption and employee work travel
