Three pathways to achieve global climate and sustainable development goals
10/30/2024 - Sustainable lifestyles, green-tech innovation, and government-led transformation each offer promising routes to make significant progress towards the UN Sustainable Development Goals (SDGs) and the Paris Agreement, according to a new study by the Potsdam Institute for Climate Impact Research (PIK). The team of researchers examined how these strategies could transform consumption and production across different sectors, identifying both benefits and trade-offs for enhancing human well-being within planetary boundaries. Contrary to the belief that the path to sustainable development is increasingly out of reach, the results show that humankind has a variety of pathways to depart from its current unsustainable trajectory.

Increasing nitrogen fertilization could pollute rivers and worsen water scarcity
02/06/2024 – In the 2050s, one-third of the world's rivers could be affected by water scarcity or be polluted by nitrogen. This is the result of a study by an international team of scientists, including researchers from the Potsdam Institute for Climate Impact Research and led by scientists of Wageningen University. They assessed the scarcity of clean water under ongoing climate change and show how water pollution from intensified agriculture and untreated sewage could limit clean water supply.

Land taxation can reduce wealth inequality
11/14/2023 - Taxing land instead of capital could reduce the widening gap between rich and poor in societies, finds a new study from the Potsdam Institute for Climate Impact Research (PIK). A team of scientists shows that, in a world of rising inequality, shifting the tax burden away from capital to land taxation could restore balance and promote economic growth. Especially people with little or no wealth could benefit from land taxes, for example in the form of less rapidly rising housing costs. The few municipalities, that have implemented land rent taxation so far, have used it to finance public transport, among other infrastructure investments.

Diabetes, dementia, depression: Adapting fuel taxes could benefit people’s health
10/13/2023 - The health benefits from walking and cycling are so significant that they should be included in fuel tax design, shows of a new study published in the journal Economica. Optimal fuel tax rates would increase by 44% in the US and by 38% in the UK if the costs for the health system that arise from too little exercise were taken into account. The revenue could be used for low-carbon transport or to compensate affected households to build support for sustainable transport.

Stuck to the subway: less privileged people have fewer possibilities to adapt their mobility behaviour to heat
10/10/2023 - Extreme heat amplifies social inequalities when it comes to subway usage and mobility in big cities, a new study shows. Analyzing the effect of temperature on people’s mobility behavior in New York City, researchers from the Potsdam Institute of Climate Impact Research (PIK) find that especially in low-income areas there are little possibilities for subway users to adapt to and mitigate heat by reducing mobility. This could lead to additional heat stress and increase health risks.

Berlin could produce much of its vegetables locally
01/27/2023 - Berlin could produce a surprisingly large proportion of its vegetable requirements itself if unused areas were used for this purpose, such as flat roofs, allotments, cemetery areas that are no longer in use, or even supermarket parking lots. Researchers have now calculated this. However, the use of this land is tied to many preconditions.

Global inequality prevents effective climate protection in the land sector
12/08/2022 - Land-based climate protection in line with the Paris Agreement can only succeed by overcoming global inequality, according to a new study by the Potsdam Institute for Climate Impact Research (PIK). This requires a shift towards healthier nutrition, less food waste and lower population growth. It is also necessary to put a price on greenhouse gas emissions from agriculture and forestry at the global level.

Extreme temperatures fuel online hate speech
09/08/2022 - Temperatures above or below a feel-good window of 12-21 degrees Celsius (54-70 °F) are linked to a marked rise in aggressive online behaviour across the USA, a new study finds. Analysing billions of tweets posted on the social media platform Twitter in the USA, researchers from the Potsdam Institute for Climate Impact Research found hate speech increasing across climate zones, income groups and belief systems for temperatures too hot or too cold. This indicates limits to adaptation to extreme temperatures, and sheds light on a yet underestimated societal impact of climate change: conflict in the digital sphere with implications for both societal cohesion and mental health.

Towards food security despite climate crisis and war
09/01/2022 - To secure the world's food supply, a shift toward more plant-based and less animal-based foods is needed, researchers explain in a 'Policy Brief' published today. The Russian war of aggression on Ukraine has triggered a shortage of some agricultural products as well as gas-produced mineral fertilizers. As a result, food prices are rising. At the same time, droughts and flash floods threaten crops worldwide as the climate crisis intensifies. The researchers show the connections - and make concrete recommendations on how a food turnaround could be initiated.

SDGs failing to have meaningful impact, research warns
06/20/2022 - Sustainability has never been higher on the international agenda. But an international assessment of the Sustainable Development Goals (SDGs)—the 17 global goals used by governments, companies, and NGOs worldwide to guide action towards a prosperous and just future—shows they are having limited impact, and may instead be contributing to greenwashing. Two years into the decisive decade for humanity's future on Earth, fundamental changes are needed if we are to shift onto a sustainable and resilient path, argue the authors of the study in Nature Sustainability.

Fighting poverty and protecting the environment can only work together: Policy paper by the Potsdam Institute for the German Environment Ministry
06/02/2022 - A decent living for all people and better protection of nature and climate aren’t conflicting targets, a new scientific analysis highlights. Development goals such as reduced poverty and inequality, better health and education, and a secure supply of food and energy on the one hand interact closely with stabilizing the climate and preserving biodiversity on the other. Only together can these goals be achieved, shows a report by the Potsdam Institute for Climate Impact Research (PIK) for the German Environment Ministry on the occasion of the Stockholm+50 summit which is starting today.

How to avoid eating the world: From degrowth to a sustainable food system transformation
05/16/2022 - Proponents of degrowth have long argued that economic growth is detrimental to the environment. Now scientists show that concerning the food sector, curbing growth alone would not make our food system sustainable – but changing what we eat and putting a price on carbon would. In a first, a group led by the Potsdam Institute for Climate Impact Research (PIK) used a quantitative food and land system model to gauge the effects of degrowth and efficiency proposals on the food sector’s greenhouse gas emissions. They find that combining a dietary shift, emissions pricing, and international income transfers could make the world’s food system emissions-neutral by the end of the 21st century – providing at the same time a healthier nutrition for a growing world population.
