Earth, the planet we call home, never ceases to amaze us with its ability to regenerate when goals fall into line with sustainability. From record-breaking ocean conservation protection efforts and the slowdown in deforestation to the rapid growth of renewable energy, all these signs confirm a change in trend driven by the evolution of the production model toward decarbonization, efficient resource management, and environmental balance.
The adoption of international regulations that are more sensitive to biodiversity and technological investment in new energy sources have begun to show their first effects, positive natural capital management indicators that serve as a roadmap for the planet's present and future.
We highlight five key figures that reflect the growing momentum in environmental protection: the UN's commitment to ecosystem restoration, the decline in deforestation, and the record investment in sustainable energies, as well as efforts to officially protect 10% of the oceans and progress toward decarbonization in urban areas through the electrification of transportation.
- Progress in ecosystem restoration efforts. The UN's environmental agenda sets a clear goal for the decade from 2020 to 2030: the restoration of terrestrial and aquatic ecosystems, which are vital for sustaining human life. Specifically, the goal is to restore 350 million hectares of degraded land by the end of the decade. This measure was spearheaded by the United Nations and represents a regenerative approach with positive trade-offs, according to the same study, as it is projected to sequester between 13 and 26 gigatons of emissions while also generating economic returns of up to nine trillion dollars in ecosystem services for the restored areas.
- Fall in deforestation. Annual deforestation rates were 38% lower from 2015–2025 compared to 1990–2000, according to a 2025 UN report, with more than half of forests covered by long-term management plans. Deforestation is also declining in the Brazilian Amazon, down 11% in 2024–2025, the lowest rate in 11 years, according to data from the Brazilian government. However, the independent NGO IMAZON estimates that the rate was even lower last year.
- Record global investment in sustainable energy sources. Another positive indicator of this shift toward environmental protection is the progress made in renewable and sustainable energy sources with record levels of global investment, reaching $2 trillion in 2025, in addition to exponential growth in solar power generation, an area where Spain is a European leader and powerhouse.
Thus, the transition to renewable energy is gaining ground as a key tool for both the present and the future, as these solutions — including renewables, electrification, and improvements in energy efficiency — could account for more than 80% of the emissions reductions needed by 2030, according to the 2023 update of the International Energy Agency's (IEA) Net Zero Roadmap report.
- More Marine Protected Areas. In this regard, a key and recent milestone has been the establishment of Marine Protected Areas, which have demonstrated that marine biodiversity — including coral reefs and seagrass beds — can recover 50% faster than expected with the right conservation policies. Specifically, the study highlights that in 2026 10.01% of the ocean has been officially protected by the international community. These sanctuaries not only protect species but also act as "blue lungs" that are essential for the planet's thermal regulation.
- Ecological corridors for biodiversity. The commitment to creating biological corridors to connect different areas and species is helping transform the landscape, with significant benefits for biodiversity and the restoration of ecosystem balance. They are part of the sustainable management strategies adopted by Spain's Ministry of Agriculture to protect and improve species. These "green highways" for wildlife help connect natural areas that have become isolated, thereby regreening the agricultural landscape. They also contribute to water retention and regulation, runoff control, and nutrient absorption to protect the soil from erosion.
These figures show us that, despite the challenges, scientific solutions and public and social commitment are moving forward in the same direction. In 2026, sustainability is a necessary, profitable, and achievable investment to ensure that the legacy we leave behind for future generations is a better and more resilient planet.
