Spain has unveiled a far-reaching climate emergency strategy aimed at both accelerating the country’s transition to clean energy and improving its resilience to climate-related disasters. Prompted in part by catastrophic wildfires that scorched over 300,000 hectares, the plan introduces mandatory emissions reporting, tougher land-use rules, and an ambitious expansion of solar and hydrogen capacity.

Carbon Reporting Requirements Begin in 2026

One of the most significant policy shifts is the immediate introduction of compulsory corporate carbon reporting. Beginning in 2026, companies operating in Spain will be required to disclose their Scope 1 and Scope 2 greenhouse gas emissions based on performance from the previous year. Larger businesses will need to expand these disclosures to include Scope 3 emissions from 2028.

In addition to reporting historical data, firms must also submit forward-looking emissions reduction plans starting in 2026. These plans are expected to span at least five years and outline measurable strategies for cutting carbon output. According to the government’s statement, early engagement in 2025 is crucial, since the regulations apply retroactively.

Institutional and Policy Overhaul to Build Climate Resilience

To support the new framework, Spain is establishing a dedicated State Agency for Civil Protection and Emergencies. This institution will have permanent staffing and a clear remit to strengthen national response capabilities. The climate plan also includes a network of public "climate refuges" and introduces stricter forest management rules to mitigate wildfire risk.

Significantly, construction activity in high-risk zones will face tighter restrictions. These changes are set to reshape Spain’s housing and land-use policies by preventing development in vulnerable areas, particularly regions prone to fire, drought, or flooding.

Renewable Energy Investment Surges Forward

The emergency plan also fast-tracks Spain’s clean energy ambitions. The country is rapidly expanding its solar energy portfolio, with more than 5 gigawatts of solar projects already entering the permitting stage in the first seven months of 2025. To meet its 2030 targets, Spain will need to add an additional 21,368 megawatts of solar capacity.

Spain is also investing heavily in green hydrogen, targeting 12 gigawatts of installed electrolyser capacity by 2030. It currently accounts for 20 percent of all green hydrogen projects in the European Union, highlighting its central role in the region’s energy transition.

Vision for 2050: A Fully Renewable Energy System

Looking ahead, Spain’s long-term vision is ambitious. By 2050, the country aims for renewables to supply 100 percent of its electricity and 97 percent of its overall energy needs. Interim targets for 2030 include generating 81 percent of electricity from renewables and reducing greenhouse gas emissions by 32 percent compared to historical levels.

These goals build on substantial progress already made. As of 2025, more than half of Spain’s electricity is generated from renewable sources, placing it among Europe’s leading clean energy adopters.

The Economic Stakes and Business Opportunity

Climate-related events have cost the Spanish economy approximately €32 billion over the past five years. However, the government is positioning its climate strategy not just as a defensive measure, but as an engine for economic growth. Nearly $32 billion in clean technology investments have already been unlocked through Spain’s national recovery plan, with more expected as regulatory certainty increases.

For businesses, the implications are profound. Spain is rapidly becoming one of the European Union’s most proactive and ambitious decarbonisation markets. Companies will need to prepare for stricter compliance obligations, but also have an opportunity to participate in a growing ecosystem of clean technology and green infrastructure investment.

The message from Madrid is unambiguous. Climate leadership and economic competitiveness will go hand in hand, and businesses that adapt early stand to benefit the most.
