In December 2025, the Federal Public Prosecutor’s Office (MPF) filed a Public Civil Action (ACP) against the Municipality of Natal, the Natal City Council, the Rio Grande do Norte Institute for Sustainable Development and the Environment (IDEMA), and the Rio Grande do Norte Legislative Assembly (ALRN). The MPF intends to protect the Permanent Preservation Areas (APPs) along Natal’s coastal strip and the associated coastal ecosystem, consisting of dunes, sandbars, and coastal plains—natural barriers against erosion and the ongoing advance of the sea. 

The MPF argues that the recently approved set of regulations—comprising the Natal Master Plan (Municipal Complementary Law 208/2022), Municipal Law 7,801/2024, State Law 12,079/2025, Normative Instruction 002/2025-GS/SEMURB, and the legislation approved by Bill 662/2025—has relaxed land use and occupation regulations along the Rio Grande do Norte coast, allowing mixed-use and multifamily residential developments to be established in areas of high ecological sensitivity, which were previously considered non-buildable areas under federal law. It is argued that the contested municipal and state regulations improperly set aside the protective framework established at the federal level, notably the Forest Code, the Atlantic Forest Law, and the National Coastal Management Plan, and violate the principles of prevention, precaution, and the prohibition against environmental degradation. According to studies conducted by experts from the Federal University of Rio Grande do Norte (UFRN) and the technical unit of the MPF, land use within these APPs intensifies erosion processes and increases the risk of flooding during extreme weather events, a situation exacerbated by legislative changes and the climate emergency the regulations have ignored. The MPF argues that the legislative process contains irregularities because it disregards the requirement for free, prior, and informed consultation with potentially affected traditional communities, thereby violating ILO Convention No. 169; it also lacks public participation and compromises the assessment of environmental and social impacts, especially along the Natal coastline, a region that includes territories occupied by traditional coastal communities, recognized by the Master Plan as Special Areas of Social Interest (AEIS). In this regard, the MPF maintains that the local relaxation of restrictions on occupation of the Coastal Road is invalid and increases the population’s exposure to the impacts of climate change, putting them at risk. 

Plaintiff requests, as a preliminary measure: (i) the suspension of the effects of the contested provisions and of the environmental permits issued in the area since the new Master Plan took effect; (ii) that the defendants refrain from issuing new regulatory or administrative acts that disregard or violate the status of the Natal Coastal Road as a Protected Area (APP); (iii) that the defendants monitor, prevent, and issue fines for any new interventions in the Natal Coastal Road area that disregard the site’s status as a Protected Area (APP). On the merits, the Court is requested to annul the contested regulations, the environmental permits issued for the Natal Coastal Strip during the term of the Natal Master Plan that are not accompanied by an EIA/RIMA and are in violation of the Forest Code, and the inter-agency development of an Environmental Protection and Management Plan for the Natal Coastal Strip that considers, among other points, mitigation and adaptation measures to address erosion processes in the region.

An aim to achieve a quantifiable outcome within a given time-frame, set by an institution such as a national government.

Policy instruments are techniques or tools used by governing authorities to promote certain policies in order to achieve predetermined goals. Put simply, instruments are how a government tries to achieve its goals, with this taxonomy being focused on national policy instruments.

Risk is the potential for adverse consequences resulting from the dynamic interplay between (climate-related) hazards, exposure, and vulnerability of affected human or ecological systems.

Renewable energy means all forms of energy produced from renewable sources in a sustainable manner.

Fossil fuel is a generic term for non-renewable energy sources such as coal, fossil gas, and oil (including crude oil, and petroleum products), that can be used for electricity and heat generation. Fossil fuels are hydrocarbons formed from pressurised and heated organic material buried over millions of years.

Area of the economy in which actors engage in identical or related activities.

In human systems, the process of adjustment to actual or expected climate change and its effects, in order to moderate harm, increase resilience or exploit beneficial opportunities. In natural systems, the process of adjustment to actual climate change and its effects; human intervention may facilitate adjustment to expected climate change and its effects.

Extreme weather refers to events where a weather variable exceeds (or falls below) a threshold. Meaning it is significantly different from the average or usual weather pattern.

Terrestrial means "of the earth" and relates to the risks to ecological system that includes all living organisms and their interactions within land-based environments, such as forests, grasslands, and deserts.

Climate change can have a range of impacts on technological system. Extreme weather events can cause infrastructure failures like power outages or damage to roads and bridges, as well as the impacts from waste following natural disasters. Human activities also cause technological impacts, such as the risks posed by oil spillage and leaks.

Climate change impacts our society by disrupting the natural, economic and social systems we depend on. Physical hazards and underlying vulnerabilities can lead to increased resource competition for food and water, which can heighten the risk of conflict.

Slow onset events evolve gradually from incremental changes over many years or from increased frequency or intensity of recurring events. As defined in the Cancun Adaptation Framework (2010), slow onset events include risks and impacts from rising temperatures, desertification, biodiversity loss, land and forest degradation, glacial retreat, ocean acidification, sea level rise, and salinization.

Geohazards are adverse geological phenomenon's that are capable of causing widespread damage or loss to property, life and the environment, such as earthquakes, volcano eruptions and tsunamis. Climate change can increase the frequency and severity of some geohazards, such as landslides, and soil erosion.
