Net Zero and the Law

On September 20th, 2023, UK prime minister Rishi Sunak announced changes to the UK’s policies described as a ‘watering-down’ in a Guardian article (Horton, 2023). The date of the proposed ban on the sale of new combustion engine cars was changed from 2030 to 2035; the plan for a complete phase-out of gas boiler installations by 2035 was changed to a reduction by 80%; plans to fine landlords who failed to upgrade their properties to a certain level of energy efficiency were dropped; and the prime minister confirmed that his party would not take forward policies “such as taxing airlines properly and informing the public of the carbon footprint of meat”.

On April 18th, 2024, Scotland’s Net Zero Secretary Mairi McAllen stated that Scotland’s 2030 climate change target could not be met, though its 2045 target remained. Fankhauser (2024) pointed out that the 2030 target of a 75% reduction in greenhouse gas emissions relative to 1990 had been set in law in the Emissions Reduction Targets Act of 2019. The UK Climate Change Act also contains a legally binding long-term goal to reduce the UK’s net emissions of greenhouse gases to zero in 2050 (CCC, 2020).

Horton and Fankhauser both discuss a range of undesirable consequences which could follow a relaxation of action on climate change; a report by Fankhauser, Averchenkova and Finnegan (2018) “summarises lessons … on how climate change legislation is best structured to be effective.” This post will concentrate on legislation and the legal consequences of breaking laws on emissions reduction, rather than on environmental consequences.

The World Bank (2020) provides a guide to climate change legislation. The Guide lists twelve elements needed to assess climate laws, beginning with setting long term targets (such as net zero emissions by 2050) and ending with parliamentary oversight of executive actions and inactions. Countries which have set in law net zero targets for 2050 or earlier include Denmark, France, Germany, Norway, Sweden, and the UK. A requirement for five-year risk assessments and adaptation plans is included in UK law, and France has legislation on mandatory reporting of climate change issues. Independent expert advice is a legal requirement in Ireland, Mexico, France, and the UK, where it is provided by the Climate Change Committee. Parliamentary oversight is a legal requirement in Colombia and in the UK, where the secretary of state is required to report to Parliament on emissions annually.

The relaxation of climate change policy in the UK will no doubt be noted in other countries, and there is understandable concern that some may be encouraged to follow the UK’s example.

Actions already taken to hold governments to their declared targets illustrate some of the possible methods. Gayle (2022) reported a high court order requiring the UK government “to outline exactly how its net zero policies will achieve emissions targets”, following a legal challenge from the environmental groups Friends of the Earth, ClientEarth and the Good Law Project. Mr Justice Holgate regarded the lack of explanation or quantification in the government’s plans on meeting its emissions target as amounting to a failure to meet its obligations under the Climate Change Act of 2008. The Department for Business, Energy and Industrial Strategy was ordered to “prepare a report explaining how the policies outlined in the net zero strategy would contribute towards emissions reductions, and to present it to parliament by April 2023.” In February 2024 UK ministers were “facing court for a second time over plans to meet legally binding climate targets, after environmental groups branded revised measures “a complete pipe dream”” (Gayle, 2024).

In July 2023 the United Nations Environment Program released a report finding that “climate litigation is emerging as a key driver of concrete action being taken by governments and corporations—forcing them to commit to emissions cuts and take accountability for harming the planet” (Conley, 2023). The Global Climate Litigation Report: 2023 Status Review, was compiled jointly by UNEP and Columbia University (UNEP, 2023). It claimed that 2,280 climate cases were brought to court in 2022 (against both governments and the private sector), and UNEP’s executive director described litigation as “a key mechanism for securing climate action and promoting climate justice.” Conley cited examples including rulings by the Supreme Courts in Mexico and Brazil and by the European Court of Human Rights.

In 2020 the Mexico's Supreme Court ruled against increasing the ethanol content in fuel, arguing that regulators had exceeded their authority (Reuters, 2020). The 2022 ruling in the Brazilian case was that the Paris Agreement adopted internationally in 2015 is a human rights treaty that must take precedence over national laws (Bennett, 2022). The case was filed by four political parties “after the government failed to distribute money from the national Climate Fund”. The “supranational status” treaties on environmental law meant that there was “no legally valid option to simply omit to combat climate change.” Schonhardt (2024) reported the finding of the European Court of Human Rights in Strasbourg that “climate change is a human rights issue”. It concluded that the government of Switzerland was “violating the rights of a group of senior women by failing to seriously address the climate crisis.” Legal scholars say that the ruling could open the way for future climate cases to be brought before the court, and “could influence other prominent tribunals, including the International Court of Justice” when considering the legal obligations of other countries regarding climate change. While the United States is not directly impacted by the ruling, similar legal strategies used outside Europe might lead to the adoption of stronger measures to combat climate change in the U.S.

Commenting on the ECHR ruling in Politico, Di Sario (2024) described the Court’s decision as “definition-shifting” and claimed that “nearly 50 governments representing almost 700 million people” could face ligation over their failures to act on climate change. She quoted a legal specialist from a U.S.-based nonprofit organisation that promotes climate activism as describing the verdict “as a blueprint for how to successfully sue your own government over climate failures”. The rulings of the ECHR are binding on the 46 members of the Council of Europe, and its judgment on Switzerland included “specifics about what steps governments must take to comply with their new climate-related human rights obligations.” These included deadlines, pathways for action and the provision of evidence. The outcome of the Swiss case is expected to expand the legal concept of who can be considered a victim of climate harm, and who can be held responsible. Similar cases are at present proceeding through The International Court of Justice, the International Tribunal for the Law of the Sea and the Inter-American Court of Human Rights and are likely to “clarify the legal obligations of states to protect rights in the context of climate change.”
