Renewable Energy Directive III
The EU's most ambitious renewable energy law is now in force. RED III raises the binding target to 42.5% by 2030, introduces sector-specific sub-targets for transport, industry, and buildings, and mandates fast-track permitting for clean energy projects. Member States face a May 2025 transposition deadline -- most are running behind.
The Renewable Energy Directive III is the EU's core law for expanding clean energy. It requires that at least 42.5% of all energy consumed across the bloc come from renewable sources by 2030 -- up from roughly 23% today. That headline number is legally binding, meaning every member state must contribute. There is also a voluntary stretch goal of 45%, which the EU has encouraged but not mandated.
The directive goes well beyond a single target. It sets specific rules for individual sectors. Transport must cut greenhouse gas intensity by 14.5% or reach a 29% renewable share. Industry must increase its renewable energy use by 1.6 percentage points every year. Heating and cooling must add at least 1.1 percentage points of renewable energy annually from 2026 onward. Buildings have an indicative target of 49% renewable energy by 2030. And for the first time, the law creates binding targets for green hydrogen: 42% of industrial hydrogen must come from renewable sources by 2030.
One of the most consequential changes is in permitting. Before RED III, getting a permit for a wind farm or solar park in Europe could take four to five years. The directive introduces maximum timelines: 12 months for onshore wind and solar in designated acceleration areas, three months for rooftop solar, and one month for small heat pumps. Member states must designate these acceleration areas by February 2026, and renewable energy projects now enjoy a legal presumption of overriding public interest.
All 27 member states were supposed to transpose RED III into their national laws by May 2025. As of early 2026, most have only partially done so. The European Commission has already sent formal notices to several governments that missed the deadline, and infringement proceedings are underway. For companies in the energy sector, the practical reality is a patchwork: some countries are well ahead, others are still drafting legislation.
Revised as part of the Fit for 55 legislative package, the Renewable Energy Directive III (RED III) sets the EU's binding target for renewable energy at a minimum of 42.5% of gross final energy consumption by 2030, with an aspirational target of 45%. This ambitious revision, adopted in 2023, significantly raises the bar from the previous 32% target under RED II and establishes sector-specific sub-targets and measures designed to accelerate the deployment of renewable energy sources across electricity, heating and cooling, transport, and industry.
RED III affects energy producers, grid operators, industrial consumers, transport companies, and the construction sector. Member States must transpose the directive into national law and develop national energy plans demonstrating how they will meet their contribution to the collective EU target. The directive introduces streamlined permitting procedures for renewable energy projects, designating renewable acceleration areas where permit decisions must be made within 12 months for projects in those zones. This is a direct response to the historically slow permitting processes that have delayed wind, solar, and other renewable energy projects across Europe.
Key obligations include mandatory renewable energy shares for heating and cooling, with an annual increase of 0.8 percentage points in renewable heating at the national level and 1.1 percentage points from 2026. In the transport sector, Member States must achieve either a 14.5% reduction in greenhouse gas intensity of transport fuels or a 29% renewable energy share by 2030. Industrial hydrogen use must be sourced from renewable fuels of non-biological origin at specified percentages, creating new demand for green hydrogen production. The directive also strengthens sustainability criteria for bioenergy, requiring compliance with forest management principles and cascading use of biomass.
RED III interacts closely with the EU Emissions Trading System, as increased renewable deployment reduces demand for emission allowances and supports the overall decarbonisation trajectory. The EU Taxonomy Regulation provides the classification criteria that determine which renewable energy activities qualify as environmentally sustainable for the purposes of sustainable finance disclosures. Together, these frameworks create a mutually reinforcing system where regulatory targets, market incentives, and investment criteria all point in the direction of accelerated clean energy transition.
For businesses, RED III presents both compliance obligations and commercial opportunities. Companies in energy-intensive sectors must plan for increased renewable energy procurement, while renewable energy developers and technology providers benefit from a more favourable regulatory and permitting environment. Early alignment with RED III targets can also strengthen taxonomy alignment and sustainability reporting under CSRD, creating synergies across the regulatory landscape.
RED III introduces differentiated targets across sectors. The overall 42.5% target is binding at EU level, while sector-specific targets are transposed through national energy and climate plans.
| SECTOR | TARGET | BASELINE | METRIC | TYPE |
|---|---|---|---|---|
| Overall | 42.5%(asp. 45%) | 23% (2022) | Share of renewable energy in gross final consumption | BINDING |
| Transport | 14.5% GHG reduction OR 29% RE share | ~9.1% (2022) | GHG intensity reduction of transport fuels, or renewable energy share | BINDING |
| Heating & Cooling | +0.8 pp/yr until 2025, then 1.1 pp/yr binding from 2026 | ~23% (2022) | Annual increase in renewable share in heating and cooling | BINDING |
| Industry | +1.6 pp/yr | Varies by MS | Annual increase in renewable share in industrial energy use | BINDING |
| Buildings | 49% | ~33% (2022) | Indicative renewable share in building energy consumption by 2030 | INDICATIVE |
| Hydrogen (industry) | 42% by 2030(asp. 60% by 2035) | <1% (2022) | Share of RFNBOs in industrial hydrogen consumption | BINDING |
Sector-specific targets are additional to the overall 42.5% headline target. Member States must demonstrate in their National Energy and Climate Plans (NECPs) how each sector contributes to the aggregate, avoiding double-counting across electricity, heating, transport, and industry.
The May 2025 transposition deadline has passed. Most Member States have achieved partial transposition; several are significantly delayed.
EEG 2023 amendments cover most targets; acceleration areas legislation pending
Loi relative a l'acceleration de la production d'energies renouvelables (March 2023) pre-empts many provisions
PNIEC update aligns with 42.5% pathway; specific transposition in progress
Decreto Energia partially transposed; full alignment expected H2 2026
Klimaatwet update integrates RED III targets; permitting reform ongoing
Significant coal transition challenges; seeking Art. 4 derogation discussions
Strong existing renewables base (>60%); focused on transport and hydrogen transposition
Already exceeding 2030 targets; transposition largely completed via existing legislation
Erneuerbaren-Ausbau-Gesetz covers electricity targets; heating/cooling measures in progress
Climate Action Plan 2024 aligned; offshore wind permitting reform underway
The European Commission can launch infringement proceedings against Member States that fail to transpose directives on time. For RED III, the Commission sent letters of formal notice to several Member States in June 2025. Persistent non-transposition can result in fines imposed by the Court of Justice.
