Legislative Decree 178/2025 

Published

Amended

Legislative Decree 199/2021 implements Directive (EU) 2018/2001 on the promotion of energy from renewable sources, updating Italy’s renewable energy framework to align with EU climate and energy goals for 2030 and 2050. It defines national renewable energy objectives and the institutional, financial, and legal tools needed to increase the share of renewables, coordinated with the NECP and the Recovery and Resilience Facility Plan. The decree sets out support schemes and incentive mechanisms for renewable electricity, heat, biogas and biomethane, regulates energy sharing, self-consumption, and renewable energy communities, and introduces rules for transitioning from old to new incentive mechanisms. It also includes provisions on simplifying permitting, promoting energy storage and electric vehicle charging infrastructure, and establishing sustainability criteria for biofuels.
The Legislative Decree 190/2024, supplemented by provisions from the Legislative Decree 178/2025, streamlines and reorganises the permitting regimes for renewable energy plants in Italy, introducing clearer categories (free activity, simplified procedure, and single authorisation) to accelerate project approval and strengthen the implementation of Legislative Decree 199/2021.

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.

Groups  of people who are adversely affected by climate change or the response to it

A set of principles, processes, and practices that build economic and political power to shift from an extractive economy to a regenerative economy.

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.

Molecules in the atmosphere that play a key role in the greenhouse effect by trapping heat radiating from Earth’s surface.

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.

The management and allocation of funds, assets and investments to meet various objectives

Any compulsory, unrequited payment to the government levied on corporations or individuals. This can be for environmental reasons, such as introducing a Carbon tax to set a price that emitters must pay for the greenhouse gases they emit.

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.

Actions or measures to adapt terrestrial systems to climate change.

This sector includes firms and individuals offering specialised expertise in fields such as law, accounting, consulting, science and engineering.

Energy derived from biological compounds that are renewable due to their short life cycle within the carbon dioxide cycle.

Activities involving the catching, processing, and selling of fish for food, recreation, and industry.

A tax advantage is an economic benefit applied to certain accounts or investments that are, by law, tax-reduced, tax-deferred, or tax-free. This can apply to investments in areas such as green energy projects or the agricultural sector, where tax advantages can help manage financial risks.

Activities of businesses and institutions that provide financial services and products to individuals and organisations.

Actions to adapt human health, healthcare systems and well-being to climate change.

Air pollution involves harmful contaminants in the air, affecting both indoor and outdoor environments. It can lead to health issues like respiratory diseases and heart problems, and climate impacts such as global warming. Pollutants can damage plants, trees, habitats, and water bodies like rivers and lakes.

A commitment to balance GHG emissions with removal by a certain point in time, effectively reducing the net emissions to zero

Activities that relate to the production of goods and services from forests.

Oil is a combustible liquid fossil fuel composed mainly of hydrocarbons, occurring as crude oil and refined into petroleum products such as petrol, diesel and kerosene.

Actions and measures to adapt and increase resilience of societies and the economy to climate change.

Actions or measures to adapt freshwater systems to climate change.

Electricity generation from devices driven by the movement of salt water, differences in saltwater temperatures, or salinity gradients.

This sector involves managing waste treatment, sanitation, pollution control and environmental cleanup.

Electrical energy generated from mechanical devices driven by flowing fresh water.

Production of electricity and heat from solar irradiation.

Activities that involve planning, designing and building infrastructure, residential, and commercial structures.

Conditions that enhance the feasibility of adaptation options. Enabling conditions include finance, technological innovation, strengthening policy instruments, institutional capacity, multi-level governance and changes in human behaviour and lifestyles.

This sector involves the distribution, treatment, and conservation of water resources.

Coastal zone and marine-related actions and measures to adapt and increase resilience to climate change

Codes and standards are regulatory instruments that specify minimum standards to protect health and safety. This ranges from performance standards, which prescribe outcomes while allowing flexibility to achieve compliance, to the more prescriptive approach of technology-specific standards.

This sector involves activities to move goods and people, alongside the storage of products.

Fossil gas, commonly known as natural gas, is a fossil fuel consisting chiefly of methane with smaller amounts of other hydrocarbons and trace gases, found in underground deposits.

A long-lived, colourless gas, chiefly emitted from fossil fuel combustion, deforestation and cement production.

This sector involves the wholesale and retail selling of goods.

A subsidy is a direct or indirect payment to individuals or businesses, typically provided as a government cash payment or a specific tax reduction.

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.
