Neubauer v Germany (24 March 2021) 1 BvR 2656/18 (also the Klimaschutz case) is a landmark German constitutional law case, concerning the duty of the German federal government to take action to prevent climate damage.
Luisa Neubauer and others brought a constitutional complaint against the Federal Climate Change Act, that the Germany government was not acting quickly enough to comply with constitutional rights in the Grundgesetz 1949, including the right to life and the duty to protect the environment.
The German Constitutional Court held that the government had a duty to speed up its climate protection measures, as part of its constitutional duty to protect the rights to life and the environment under, respectively, article 2 and article 20a of the Grundgesetz 1949. It held that the causal link between manmade emissions and climate change, that all release of CO2 caused more warming, and that any carbon budget was limited. It rejected that because Germany could not stop global warming alone, it did not have responsibility: on the contrary it was necessary that Germany undertook action to encourage others to do so and international cooperation. The Court said the following. [1]
119. There is a direct causal link between anthropogenic climate change and concentrations of human-induced greenhouse gases in the Earth’s atmosphere (...). CO2 emissions are particularly significant in this regard. Once they have entered the Earth’s atmosphere, they are virtually impossible to remove as things currently stand. This means that anthropogenic global warming and climate change resulting from earlier periods cannot be reversed at some later date. At the same time, with every amount of CO2 emitted over and above a small climate-neutral quantity, the Earth’s temperature rises further along its irreversible trajectory and climate change also undergoes an irreversible progression. If global warming is to be halted at a specific temperature limit, nothing more than the amount of CO2 corresponding to this limit may be emitted. The world has a so-called remaining CO2 budget. If emissions go beyond this remaining budget, the temperature limit will be exceeded.

202. Either way, the obligation to take national climate action cannot be invalidated by arguing that such action would be incapable of stopping climate change. It is true that Germany would not be capable of preventing climate change on its own. Its isolated activity is clearly not the only causal factor determining the progression of climate change and the effectiveness of climate action. Climate change can only be stopped if climate neutrality is achieved worldwide. In view of the global reduction requirements, Germany’s 2% share of worldwide CO2 emissions (...) is only a small factor, but if Germany’s climate action measures are embedded within global efforts, they are capable of playing a part in the overall drive to bring climate change to a halt....
203. The state may not evade its responsibility here by pointing to GHG emissions in other states. (...) On the contrary, the particular reliance on the international community gives rise to a constitutional necessity to actually implement one’s own climate action measures at the national level – in international agreement wherever possible. It is precisely because the state is dependent on international cooperation in order to effectively carry out its obligation to take climate action under Art. 20a GG that it must avoid creating incentives for other states to undermine this cooperation. Its own activities should serve to strengthen international confidence in the fact that climate action – particularly the pursuit of treaty-based climate targets – can be successful while safeguarding decent living conditions, including in terms of fundamental freedoms. In practice, resolving the global climate problem is thus largely dependent on the existence of mutual trust that others will also strive to achieve the targets.
The scientific community has been investigating the causes of climate change for decades. After thousands of studies, it came to a consensus, where it is "unequivocal that human influence has warmed the atmosphere, ocean and land since pre-industrial times." This consensus is supported by around 200 scientific organizations worldwide, The dominant role in this climate change has been played by the direct emissions of carbon dioxide from the burning of fossil fuels. Indirect CO2 emissions from land use change, and the emissions of methane, nitrous oxide and other greenhouse gases play major supporting roles.
The United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany.
This glossary of climate change is a list of definitions of terms and concepts relevant to climate change, global warming, and related topics.
Greenhouse gas (GHG) emissions from human activities intensify the greenhouse effect. This contributes to climate change. Carbon dioxide, from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the United States. The United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies. Emissions from human activities have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but have been consistent among all greenhouse gases. Emissions in the 2010s averaged 56 billion tons a year, higher than any decade before. Total cumulative emissions from 1870 to 2017 were 425±20 GtC from fossil fuels and industry, and 180±60 GtC from land use change. Land-use change, such as deforestation, caused about 31% of cumulative emissions over 1870–2017, coal 32%, oil 25%, and gas 10%.
Climate change has resulted in an increase in temperature of 2.3 °C (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
Representative Concentration Pathways (RCP) are climate change scenarios to project future greenhouse gas concentrations. These pathways describe future greenhouse gas concentrations and have been formally adopted by the IPCC. The pathways describe different climate change scenarios, all of which were considered possible depending on the amount of greenhouse gases (GHG) emitted in the years to come. The four RCPs – originally RCP2.6, RCP4.5, RCP6, and RCP8.5 – are labelled after a possible range of radiative forcing values in the year 2100. The IPCC Fifth Assessment Report (AR5) began to use these four pathways for climate modeling and research in 2014. The higher values mean higher greenhouse gas emissions and therefore higher global surface temperatures and more pronounced effects of climate change. The lower RCP values, on the other hand, are more desirable for humans but would require more stringent climate change mitigation efforts to achieve them.
A carbon budget is a concept used in climate policy to help set emissions reduction targets in a fair and effective way. It examines the "maximum amount of cumulative net global anthropogenic carbon dioxide emissions that would result in limiting global warming to a given level". It can be expressed relative to the pre-industrial period. In this case, it is the total carbon budget. Or it can be expressed from a recent specified date onwards. In that case it is the remaining carbon budget.
The transient climate response to cumulative emissions of carbon dioxide (TCRE) is the ratio of the globally averaged surface temperature change per unit carbon dioxide (CO2) emitted.
The Special Report on Global Warming of 1.5 °C (SR15) was published by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018. The report, approved in Incheon, South Korea, includes over 6,000 scientific references, and was prepared by 91 authors from 40 countries. In December 2015, the 2015 United Nations Climate Change Conference called for the report. The report was delivered at the United Nations' 48th session of the IPCC to "deliver the authoritative, scientific guide for governments" to deal with climate change. Its key finding is that meeting a 1.5 °C (2.7 °F) target is possible but would require "deep emissions reductions" and "rapid, far-reaching and unprecedented changes in all aspects of society". Furthermore, the report finds that "limiting global warming to 1.5 °C compared with 2 °C would reduce challenging impacts on ecosystems, human health and well-being" and that a 2 °C temperature increase would exacerbate extreme weather, rising sea levels and diminishing Arctic sea ice, coral bleaching, and loss of ecosystems, among other impacts.
Greenhouse gas emissionsbyRussia are mostly from fossil gas, oil and coal. Russia emits 2 or 3 billion tonnes CO2eq of greenhouse gases each year; about 4% of world emissions. Annual carbon dioxide emissions alone are about 12 tons per person, more than double the world average. Cutting greenhouse gas emissions, and therefore air pollution in Russia, would have health benefits greater than the cost. The country is the world's biggest methane emitter, and 4 billion dollars worth of methane was estimated to leak in 2019/20.
State of the Netherlands v Urgenda Foundation (2019) is climate change litigation heard by the Supreme Court of the Netherlands related to government efforts to curtail carbon dioxide emissions. The case was brought against the Dutch government in 2013, arguing the government, by not meeting a minimum carbon dioxide emission-reduction goal established by scientists to avert harmful climate change, was endangering the human rights of Dutch citizens as set by national and European Union laws.

Milieudefensie v Royal Dutch Shell (2021) is a human rights law and tort law case heard by the district court of The Hague in the Netherlands in 2021 related to efforts by several NGO's to curtail carbon dioxide emissions by multinational corporations. It was brought by the Dutch branch of Friends of the Earth and a group of other NGO's against the oil corporation, Shell plc. In May 2021, the court ordered Shell to reduce its global carbon emissions from its 2019 levels by 45% by 2030, relating not only to the emissions from its operations, but also those from the products it sells. It is considered to be the first major climate change litigation ruling against a corporation.
Lliuya v RWE AG (2015) Case No. 2 O 285/15 is a German tort law and climate litigation case, concerning liability for climate damage in Peru from a melting glacier, against Germany's largest coal burning power company, RWE, which has caused approximately 0.47% of all historic greenhouse gas emissions. It is currently on appeal in the Upper State Court, Oberlandesgericht Hamm.
Smith v Fonterra Co-Operative Group Ltd [2024] NZSC 5 is a landmark New Zealand tort law case, concerning liability of major fossil fuel polluters for climate damage. The NZ Supreme Court held that polluting companies could be liable in tort to pay damages from global warming and rising sea levels to people whose coastal property is damaged, overturning courts below.
Verein KlimaSeniorinnen Schweiz v. Switzerland (2024) was a landmark European Court of Human Rights case in which the court ruled that Switzerland violated the European Convention on Human Rights by failing to adequately address climate change. It is the first climate change litigation in which an international court has ruled that state inaction violates human rights.
