A Net Zero future for all

Net zero buildings are not just about engineering efficiency — they are about rethinking how we live, how we share space, and how we care for the world that shelters us.

Global Network for Zero (GNFZ) is the world’s first independent certifier of Net Zero standards. Their powerful, user-friendly platform—aligned with the GHG Protocol—offers progressive certifications for emissions, energy, water, and waste, applicable to:

New and existing buildings
Real estate
Businesses

SPHERA + Global Network for Zero

We are proud to be an official partner of Global Network for Zero. Through this collaboration, we work hand-in-hand to:

Assess carbon footprints, energy/water use, and waste generation
Design custom Net Zero roadmaps
Implement actionable strategies
Certify projects and ensure continued compliance year after year

Accelerating the Net Zero Mission – Together

This partnership strengthens our mission to deliver global, reliable, and effective sustainability services.

Global credibility: Access to a third-party Net Zero certificate aligned with the GHG Protocol, widely trusted by investors and ESG frameworks
Efficient digital platform: Simplifies the process of tracking and certifying progress
Milestone-based recognition: Track and celebrate every step, from baseline assessments to full Net Zero achievement

These new technologies are good tools for countries to be aware of and avoid irregularities. Also, being able to keep data always up to date without the need for countries to spend resources on collecting it themselves.

Based in Costa Rica, working everywhere

Based in Costa Rica, but SPHERA operates internationally. Our approach is fully digital and scalable, enabling us to support projects across the U.S., Latin America, and beyond. We adapt to each region’s regulations, climate, and sustainability goals.

Support more certified projects—from buildings to entire business portfolios
Strengthen market presence in high-demand regions like the United States
Collaborate globally with other GNFZ partners and experts
Boost visibility through internationally recognized certifications integrated into ESG reporting (like GRESB and SBTi)
