COP29: PIK and KfW launch financing concept for carbon removals at world climate summit
11/11/2024 - Since the reduction of CO2 emissions is too slow to limit global heating to 1.5°C, a great deal of CO2 must be removed from the atmosphere. Depending on the scenario, this will cost up to 2 percent of annual global economic output in 2050. This effort is economically imperative because the climate damage per tonne of CO2 is many times higher. However, this would overburden state budgets, so a financial architecture is needed to mobilise private capital. The Potsdam Institute for Climate Impact Research (PIK) and KfW, one of the world’s leading promotional banks, are now making a joint proposal at the World Climate Summit.

How a carbon central bank can turn Europe into a CO2 “eater”
09/17/2024 - The EU has decided to achieve climate neutrality by 2050. From then on, for every tonne of CO2 still emitted, one tonne would have to be taken out of the atmosphere. A European Carbon Central Bank could play a key role on the way there - and use market-based incentives to set the course for a net-negative emissions balance in the second half of the century, turning Europe into a CO2 “eater”, so to speak. Ottmar Edenhofer, Director of the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute on Global Commons and Climate Change (MCC), explained how this could work economically in the renowned “Thünen Lecture”.

What Works: Groundbreaking Evaluation of Climate Policy Measures Over Two Decades
08/23/2024 - An international research team has unveiled the first comprehensive global evaluation of 1,500 climate policy measures from 41 countries across six continents. Published in the prestigious journal Science, this unprecedented study provides a detailed impact analysis of the wide range of climate policy measures implemented over the last two decades. The findings reveal a sobering reality: many policy measures have failed to achieve the necessary scale of emission reductions. Only 63 cases of successful climate policies, leading to average emission reductions of 19 percent, were identified. The key characteristic of these successful cases is the inclusion of tax and price incentives in well-designed policy mixes.

Securing competitiveness of energy-intensive industries through structural change: The pulling power of renewables
04/23/2024 - Countries with limited potential for renewables could save up to 20 percent of costs for green steel and up to 40 percent for green chemicals from green hydrogen if they relocated their energy-intensive production and would import from countries where renewable energy is cheaper, finds a new study by the Potsdam Institute for Climate Impact Research (PIK). This ‘renewables pull’ would create strong incentives for businesses to invest in low-emission production facilities in these renewable-rich countries. Renewable-scarce countries could put all focus on down-stream production and refinement as the smart way to secure industrial competitiveness.

38 trillion dollars in damages each year: World economy already committed to income reduction of 19 % due to climate change
04/17/2024 - Even if CO2 emissions were to be drastically cut down starting today, the world economy is already committed to an income reduction of 19 % until 2050 due to climate change, a new study published in “Nature” finds. These damages are six times larger than the mitigation costs needed to limit global warming to two degrees. Based on empirical data from more than 1,600 regions worldwide over the past 40 years, scientists at the Potsdam Institute for Climate Impact Research (PIK) assessed future impacts of changing climatic conditions on economic growth and their persistence.

Electrification or hydrogen? Both have distinct roles in the European energy transition
02/16/2024 - A key step to achieving climate neutrality in the European Union is to rapidly shift from fossil fuels to electric technologies powered by renewable energies, a new study shows. At the same time, hydrogen produced from electricity will also be indispensable in hard-to-electrify sectors such as aviation, shipping and chemicals. By 2050, electrification and hydrogen are the key strategies to reach climate neutrality based on renewable power. Future EU transformation scenarios modeled by scientists from the Potsdam Institute for Climate Impact Research PIK investigate the roles of electrification and hydrogen and find that shares of 42-60% for electricity and 9-26% for hydrogen-based energy are required in total energy consumption by 2050.

Transforming food systems could create multi-trillion dollars of economic benefits every year
01/29/2024 - Transforming food systems around the world would lead to socio-economic benefits summing up to 5 to 10 trillion USD a year, shows a new global policy report produced by leading economists and scientists of the Food System Economics Commission (FSEC). The most ambitious and comprehensive study of food system economics so far underlines that food systems are currently destroying more value than they create and that an overhaul of food system policies is urgently needed. On the other hand, the cost of transformation would be much lower than the potential benefits, offering a better life to hundreds of millions of people.

More new fossil gas heating systems, only tentative progress: energy transition update
11/22/2023 - Reduced fossil fuel consumption due to the energy crisis, tentative positive signs in the expansion of renewable energy capacities, electric cars and heat pumps – but all this is not happening fast enough, according to new figures from the Ariadne Transformation Tracker. Moreover, the German energy transition is not yet on track when it comes to phasing out fossil fuels in the heating and transport sectors. Instead of the necessary decline, there has been a clear increase in the sale of new cars with combustion engines and new gas heating systems compared to the previous year.

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.
