Chile Climate Change Policy: What's Not Being Said?
Chile's climate change policy just took a bold turn
Chile's climate change policy has entered a decisive new phase with the full rollout of its 2022 Framework Law on Climate Change, a legally binding roadmap that commits the country to net zero greenhouse gas emissions by 2050 and to peaking emissions by 2025 under its updated Nationally Determined Contribution (NDC). Since the law's passage, Santiago has accelerated its coal phase-out, tightened approval rules for new fossil-fuel projects, and required every ministry, region, and municipality to produce sectoral and local climate action plans aligned with that 1.5°C-compatible trajectory. A recent shift in presidential leadership has softened some near-term environmental rules, but the core architecture of climate policy-including binding long-term targets, carbon pricing, and sectoral mitigation plans-remains intact.
Core pillars of Chile's climate framework law
The Chilean Framework Law on Climate Change (Ley Marco de Cambio Climático, LMCC 21.455), enacted in June 2022, converted Chile's original 2020 NDC and 2050 greenhouse gas neutrality pledge into domestic law rather than aspirational policy. Under the law, 17 national ministries plus regional and municipal governments must now develop and implement climate plans, embedding mitigation and adaptation into budgets, regulations, and infrastructure decisions.
- 2050 net zero target: The law legally entrenches Chile's commitment to reach net zero greenhouse gas emissions by mid-century, with a 2030 emissions cap anchored in the 2020 NDC.
- Coal-phase out schedule: The government has advanced its coal exit from an initial 2040 horizon to a de facto 2035-2037 window, with about 70% of coal-fired capacity scheduled for closure or conversion by 2026.
- Investment compatibility criteria: New public and private projects must prove alignment with national climate goals, including a credible decarbonisation or reconversion pathway to avoid carbon lock-in.
By distributing climate responsibility across ministries, the framework effectively ends the practice of treating climate as a niche "environment ministry" issue and instead frames it as a cross-cutting requirement for national development. Financial institutions and infrastructure planners now face explicit obligations to integrate climate risk, including stress-testing portfolios against a 1.5°C scenario and to align with a nascent "green taxonomy" still under development.
Recent milestones in mitigation and adaptation
In 2023-2026, Chile has used the framework law to lock in concrete sectoral measures, including a 2025 peak-year declaration for national emissions, a 25% reduction goal for black carbon by 2030, and a raft of measures targeting electricity, transport, industry, and nature-based solutions. The country's share of renewable electricity in the grid has risen from about 46% in 2021 to roughly 70% by 2026, driven by wind, solar, and storage expansion in the Atacama and central regions.
Key policy milestones include:
- Coal-plant retirement plan: Announced in 2019 and reinforced under the framework law, the schedule now foresees 70% of coal-fired capacity retired or retrofitted for biomass and renewables by 2026, with full phase-out on the table by 2035 pending political signals from President José Antonio Kast's administration.
- Transport electrification push: An energy-transition agenda targets 80% of new light-duty vehicle sales as electric by 2035 and 2030 for urban buses, underpinned by higher fuel taxes and expanded EV-charging infrastructure.
- Carbon pricing and green hydrogen: Chile has raised its carbon tax on power and fossil fuels and begun piloting regulatory frameworks for green hydrogen exports, seeking to leverage its renewable surplus to decarbonise both domestic and international sectors.
- Nature-based solutions: The updated NDC specifically integrates reforestation, native-forest restoration, and improved water-risk monitoring as core adaptation pillars, with target reductions in black carbon aimed at easing pressure on Andean glaciers and water supplies.
Adaptation policy has likewise shifted from top-down planning to participatory, subnational planning: the framework law obliges all 16 regions and 300+ municipalities to produce climate action plans, with several pilot municipalities-such as San José de Maipo-already adopting local plans that address water stress, wildfire risk, and urban heat.
Climate performance and international standing
Independent assessments, including the Climate Action Tracker and the Climate Change Performance Index, rate Chile as "almost sufficient" relative to a 1.5°C pathway, recognising that current policies fall short of full alignment but could close the gap with moderate strengthening. If all countries followed Chile's current approach, the world would likely stay below 2°C but not "well below" it, according to the latest modelling.
The following table illustrates how Chile's headline targets compare with key international benchmarks as of 2026:
| Metric | Chile's target under LMCC / NDC | Global 1.5°C benchmark |
|---|---|---|
| 2030 NDC cap | Unconditional target: about 1.2-1.3 Gt CO₂-eq abated vs 2017 baseline by 2030, equivalent to roughly 30-35% below BAU. | Global 1.5°C pathway: 43% global emissions cut by 2030 vs 2019. |
| 2050 goal | Net zero greenhouse gas emissions by 2050, legally enshrined in LMCC. | Global net zero by 2050, per IPCC AR6. |
| Coal phase-out | 70% of coal-fired capacity retired or converted by 2026; full phase-out under discussion for 2035 rather than initial 2040. | Global 1.5°C pathway: near-complete coal phase-out by early 2030s. |
| Fossil gas "transition" role | Gas remains in the medium-term mix, but new projects face stricter climate-compatibility reviews and must show credible decarbonisation plans. | 1.5°C-compatible scenarios: gas demand must fall steeply by 2035. |
International observers praise Chile's rapid renewable rollout and the institutionalisation of climate planning but flag weak enforcement, fragmented monitoring, and lingering influence from powerful fossil-fuel and mining interests as drag factors.
Market and investment mechanisms
Chile has been one of the most active emerging markets in carbon markets and international climate finance, using Article 6 of the Paris Agreement to structure emission-transfer frameworks for foreign investors. In 2023, Santiago signed a bilateral Article 6 agreement with Switzerland under which Swiss funds finance emissions-reduction projects in Chile in exchange for Internationally Transferred Mitigation Outcomes (ITMOs).
In October 2025, Chile authorised the first project under this regime, a coal-boiler conversion to a biomass-fired system in the Ñuble region, projected to cut roughly 1.2 million tonnes of CO₂ over 10 years. The framework also enables higher-value credits in sectors such as forestry, waste management, and distributed renewables, provided projects meet robust verification standards and avoid leakage or double counting.
Domestically, Chile's carbon tax on power and fossil fuels has risen to around USD 25-30 per tonne of CO₂, calibrated so that it influences investment decisions without triggering abrupt price shocks. Concurrently, the government is building a "green taxonomy" to guide banks and pension funds toward climate-aligned investments, with pilots focusing on low-carbon transport, renewable energy, and water-efficient infrastructure.
Political shifts and recent regulatory rollbacks
While the 2022 framework law remains intact, the 2026 change in presidency has introduced a more conservative stance on near-term environmental regulation. In March 2026, President José Antonio Kast's administration suspended roughly 43 environmental decrees introduced in the final months of former President Gabriel Boric's term, including measures on emissions monitoring, pollution controls, and protected-area management.
These revocations touch on several environmental protections that had sought to tighten permitting for industrial projects, expand protected-area buffers, and tighten air-quality standards. Analysts note that the moves do not overturn the core climate targets or the framework law but may slow the pace of implementation and encourage weaker enforcement at the subnational level.
Nevertheless, the decarbonisation architecture-binding 2050 neutrality, sectoral mitigation plans, and compatibility criteria for new projects-creates a "path dependence" that constrains how far back the climate agenda can be rolled, even under a more fossil-friendly administration.
In sum, Chile's climate change policy has evolved from high-ambition pledges into a legally backed, multi-sector framework that is now being tested by political headwinds and implementation gaps. The country's ability to maintain its reputation as a regional climate leader will hinge on whether it can enforce coal-phase-out deadlines, safeguard Article 6 and carbon-pricing mechanisms, and translate the framework law's sectoral and local mandates into tangible, measurable emissions reductions over the next decade.
Key concerns and solutions for Chile Climate Change Policy Whats Not Being Said
What is Chile's main climate change law?
Chile's main climate change law is the Framework Law on Climate Change (Ley Marco de Cambio Climático, LMCC 21.455), passed in June 2022, which legally entrenches a 2050 net zero greenhouse gas target and requires all sectors and levels of government to produce climate action plans.
When does Chile aim to phase out coal?
Chile now plans to retire or convert about 70% of its coal-fired power capacity by 2026 and has signalled intentions to bring forward the full coal phase-out from the original 2040 horizon to 2035 or earlier, depending on grid readiness and political direction.
How does Chile's climate policy affect new energy projects?
Under the framework law, new energy projects must pass "compatibility criteria" reviews that assess their alignment with Chile's 2030 NDC and 2050 neutrality targets, including a credible pathway for decarbonisation or conversion to green technologies, which discourages long-lived fossil-intensive designs.
Is Chile aligned with 1.5°C?
Independent experts rate Chile as "almost sufficient" for a 1.5°C pathway, noting that current policies would limit warming below 2°C if globalised but would require stronger coal-phase-out speed, faster gas reduction, and stricter implementation to fully align with 1.5°C.
What role does green hydrogen play in Chile's climate strategy?
Chile includes green hydrogen as a key pillar, aiming to leverage its high-quality wind and solar resources to produce low-cost, export-oriented hydrogen for heavy industry and shipping, complemented by pilot regulations and offtake agreements with international partners.
How are municipalities involved in Chile's climate policy?
The framework law obliges all 16 regions and over 300 municipalities to draft climate action plans, with pilot cities such as San José de Maipo already approving local blueprints that integrate water-risk management, wildfire prevention, and low-carbon urban planning.
