Portugal's Renewable Energy 'Green Map' Plan Triggers Environmental Concerns

The Portuguese government has introduced the Programa Sectorial das Zonas de Aceleração de Energias Renováveis (PSZAER), dubbed the “green map,” to speed up the deployment of solar photovoltaic and on‑shore wind projects. The plan designates roughly 7% of the mainland—about 371,000 hectares for solar and 84,000 hectares for wind—as zones eligible for streamlined licensing and exemption from a full environmental impact assessment, though developers must still undergo a compatibility verification.

Critics, including the National Association of Municipalities, the Directorate‑General of Agriculture, the environmental agencies APA and ICNF, and regional commissions, warn that the initiative could lead to landscape saturation, loss of agricultural soils, and “monofunctionalisation” of interior areas. They argue that the cartography used overstates suitable land and that the exemptions may bypass necessary safeguards.

Commentary accompanying the proposal stresses that replacing large tracts of land with megaparques solares may overlook the climate‑resilience benefits of forests. Trees provide carbon capture, temperature regulation, water infiltration, erosion control, biodiversity protection and public‑health advantages. The debate calls for integrating forest, agriculture, conservation and renewable‑energy planning rather than prioritising a purely technological solution.
