Biodiversity is now a key issue in real estate projects. But assessing the extent to which it is taken into account in a project is often confusing: between self-declared scores, sector labels and independent diagnostics, not all approaches are equal. Faced with the demands of green taxonomy, CSRD and ESG investors, the issue is no longer just "doing", but being able to prove it. In this article, we offer a clear reading of the different approaches, and explain why the choice of an independent, evidence-based biodiversity diagnostic is today the foundation of a credible approach.

The real effectiveness of urban planting against the heat island: what scientific studies say. How effective are urban trees in reducing urban temperatures? Analysis of scientific data and key success factors.

In sustainable investment, promises are no longer enough. Between ESG declarations and impact ambitions, credibility depends on proof. Measuring, tracking and certifying: three requirements to ensure that commitment does not remain a communications exercise.

Mipim 2025, like many other major real estate events, confirmed a major trend: ESG is making its way into strategic discourse, and investors are now being asked to think long-term. Think 2035, imagine sustainable portfolios, integrate societal expectations. But behind all this ambition, one question persists: how can we ensure that these visions are more than just promises? How can we prevent strategy from remaining a declarative exercise, with no tools to objectify impacts? At IRICE, we have a simple conviction: the credibility of an ESG approach depends not on communication, but on measurement. On the ability to certify, structure and demonstrate. In this article, we explore what distinguishes a sincere ambition from a promise without proof. And why, in the face of ecological challenges, independent certification has become a strategic requirement.

Introduced by journalist Richard Louv in his book Last Child in the Woods (2005), the concept of "nature deficit disorder" refers to the physical, psychological and cognitive disorders linked to the growing disconnection between humans - particularly children - and natural environments.

The growing importance of ESG obligations and the Sustainable Development Goals (SDGs) has led to an increasing demand for rigor in extra-financial reporting. Behind this requirement lies a structuring principle: only objectively verifiable and traceable information is now admissible in company reports and publications. In this context, certification by an accredited body becomes a strategic lever as much as a compliance tool.
