In collaboration with the newspaper taz, we designed and produced both physical and digital postcards containing visualizations covering various aspects of climate protection and mitigation in Germany. For each of the 401 districts and 16 states in Germany, the reader can explore climate protection postcards in the five sectors: energy, mobility, buildings, agriculture, and waste. The goal of our research is to study readers’ engagement with data visualizations on the topic of climate protection — across multiple media channels. A central ambition here is that the communication of climate change should not cause readers to feel anxious, numb, or even enter a state of shock, but develop an interest and engage locally with climate change and its ramifications.


As data visualization has become an important tool across several domains to discuss climate protection, mitigation, and adaptation, we explore its role in fostering readers’ engagement on these topics across several platforms. Drawing on research about climate journalism and data visualization, we identified a series of difficulties in effectively engaging readers: the lack of local content, the favoring of education over action framing, and little diversification of content across platforms. 

Throughout the project, we extensively discussed visualization ideas and more broadly how data could be presented to readers within a holistic design frame. As a result, we developed the concept of climate protection postcards, photographic or illustrated cards typically sent via mail from holiday locations. The concept lends itself well both to physical and digital environments, giving us the possibility to design a virtually infinite number of artifacts that sliced indicators’ data according to districts. 

These hybrid  – both digital and physical – postcards are aimed specifically to readers, with the goal of engaging them in local climate protection. Our intention was to foster exploration and comparison of different regions to show the regional relevance of climate protection. The postcards are spread across various newspaper publication channels.

The journalists are able to embed the postcards on the homepage of the newspaper website and in articles via an iframe. They can alter the presentation of the postcards in four different modes and hereby customize them according to the needs of a given article.

The default mode without any set parameters shows a previewed data visualization of all five sectors for Germany.

The Landkreis mode displays one defined region with its five sectors. In this mode the journalists are able to decide which region should be shown, which can later be changed by the reader when exploring the data.

The comparison mode allows to compare up to five regions in one specific sector. Again, the sector and compared regions can later be exchanged by the reader.

When embedded in a topic-specific article, e.g. organic waste in Potsdam, journalists can select the respective region (Potsdam) and sector (Waste) and include the appropriate postcard in full size. 

Additionally, more settings regarding the user interface and the shown postcard data can be set. 

On the back of each postcard is a descriptive text of both the visualized data on the front side and the projected climate future of the selected region. A colored map of Germany enables the reader to jump to other regions. The coloring is based on the sector rating of the respective district. Green represents the upper third, yellow the middle and red the lower third. 


Klimakarten has been a collaboration with the newspaper taz, in particular with Luise Strothmann, Lalon Sander, Jean-Philipp Baeck, and Jelene Malkowski. This research is connected with the project “VIDAN: Visual and dynamic arrangements of narratives”, which is funded by the Federal Ministry of Education and Research and conducted at FHP’s UCLAB.

From shock to shift: Data visualization for constructive climate journalism

— IEEE VIS / TVCG: IEEE Transactions on Visualization and Computer Graphics, 2023
We present a multi-dimensional, multi-level, and multi-channel approach to data visualization for the purpose of constructive climate journalism. Data visualization has assumed a central role in environmental journalism and is often used in data stories to convey the dramatic consequences of climate change and other ecological crises. However, the emphasis on the catastrophic impacts of climate change tends to induce feelings of fear, anxiety, and apathy in readers. Climate mitigation, adaptation, and protection—all highly urgent in the face of the climate crisis—are at risk of being overlooked. These topics are more difficult to communicate as they are hard to convey on varying levels of locality, involve multiple interconnected sectors, and need to be mediated across various channels from the printed newspaper to social media platforms. So far, there has been little research on data visualization to enhance affective engagement with data about climate protection as part of solution-oriented reporting of climate change. With this research we characterize the unique challenges of constructive climate journalism for data visualization and share findings from a research and design study in collaboration with a national newspaper in Germany. Using the affordances and aesthetics of travel postcards, we present Klimakarten, a data journalism project on the progress of climate protection at multiple spatial scales (from national to local), across five key sectors (agriculture, buildings, energy, mobility, and waste), and for print and online use. The findings from quantitative and qualitative analysis of reader feedback confirm our overall approach and suggest implications for future work.
