With over 30 years of global experience in technical and commercial leadership, Didier launched H2D to address what he saw as a critical disconnect between ambition and action.

Despite mounting environmental challenges and a growing chorus of ESG commitments, many companies continue to operate without embedding sustainability at the core of their decisions.

H2D was founded on the belief that carbon emissions are only part of the story. While reducing COโ‚‚ is important, focusing exclusively on carbon risks overlooking a host of other serious environmental impacts.

Didier points to issues such as freshwater scarcity, microplastic contamination, and the acidification of oceansโ€”all of which threaten ecosystems and long-term human health. Yet these impacts remain under-addressed in most corporate strategies.

This is why H2Dโ€™s work begins with enhanced lifecycle assessments (LCAs), measuring environmental impacts across a broad range of indicators. This approach gives companies a full view of their footprint and a data-driven path toward improvement.

H2Dโ€™s strength lies in its deep technical expertise. The team is made up of chemical engineers, formulation specialists, and LCA experts who understand the mechanics and realities of applied chemistry. Their solutions are rooted in the science of how molecules behave, how they are synthesized, and how they can be optimized to reduce environmental impact.

This combination of engineering knowledge and economic awareness ensures that H2Dโ€™s recommendations are not only sustainable but also feasible within clientsโ€™ operations and budgets.

Didier is candid about the fact that many companies are still making decisions based on assumptions rather than evidence.

โ€œThereโ€™s a belief that switching to bio-based materials is always better,โ€ he notes. โ€œ๐˜‰๐˜ถ๐˜ต ๐˜ธ๐˜ช๐˜ต๐˜ฉ๐˜ฐ๐˜ถ๐˜ต ๐˜ข๐˜ด๐˜ด๐˜ฆ๐˜ด๐˜ด๐˜ช๐˜ฏ๐˜จ ๐˜ช๐˜ฎ๐˜ฑ๐˜ข๐˜ค๐˜ต๐˜ด ๐˜ฐ๐˜ฏ ๐˜ธ๐˜ข๐˜ต๐˜ฆ๐˜ณ ๐˜ถ๐˜ด๐˜ฆ, ๐˜ญ๐˜ข๐˜ฏ๐˜ฅ ๐˜ค๐˜ฐ๐˜ฎ๐˜ฑ๐˜ฆ๐˜ต๐˜ช๐˜ต๐˜ช๐˜ฐ๐˜ฏ, ๐˜ข๐˜ฏ๐˜ฅ ๐˜ฑ๐˜ฆ๐˜ด๐˜ต๐˜ช๐˜ค๐˜ช๐˜ฅ๐˜ฆ ๐˜ฏ๐˜ฆ๐˜ฆ๐˜ฅ๐˜ด, ๐˜ต๐˜ฉ๐˜ข๐˜ต ๐˜ด๐˜ธ๐˜ช๐˜ต๐˜ค๐˜ฉ ๐˜ค๐˜ข๐˜ฏ ๐˜ข๐˜ค๐˜ต๐˜ถ๐˜ข๐˜ญ๐˜ญ๐˜บ ๐˜ค๐˜ณ๐˜ฆ๐˜ข๐˜ต๐˜ฆ ๐˜ฎ๐˜ฐ๐˜ณ๐˜ฆ ๐˜ฉ๐˜ข๐˜ณ๐˜ฎ ๐˜ต๐˜ฉ๐˜ข๐˜ฏ ๐˜จ๐˜ฐ๐˜ฐ๐˜ฅ.โ€

When a company approaches H2D, the process starts with a clear set of questions: What is your current situation? What do you mean by environmental impact? What are your goals?

Many companies, Didier explains, immediately respond with โ€œwe want to reduce our carbon footprintโ€ or โ€œwe want to use more bio-based products.โ€ His reply is consistent: โ€œThose are not objectivesโ€”theyโ€™re tactics. ๐˜ž๐˜ฆ ๐˜ฏ๐˜ฆ๐˜ฆ๐˜ฅ ๐˜ต๐˜ฐ ๐˜ถ๐˜ฏ๐˜ฅ๐˜ฆ๐˜ณ๐˜ด๐˜ต๐˜ข๐˜ฏ๐˜ฅ ๐˜บ๐˜ฐ๐˜ถ๐˜ณ ๐˜ง๐˜ถ๐˜ญ๐˜ญ ๐˜ค๐˜ฐ๐˜ฏ๐˜ต๐˜ฆ๐˜น๐˜ต ๐˜ข๐˜ฏ๐˜ฅ ๐˜ฅ๐˜ฆ๐˜ง๐˜ช๐˜ฏ๐˜ฆ ๐˜ข ๐˜ฎ๐˜ฆ๐˜ข๐˜ด๐˜ถ๐˜ณ๐˜ข๐˜ฃ๐˜ญ๐˜ฆ ๐˜ด๐˜ต๐˜ณ๐˜ข๐˜ต๐˜ฆ๐˜จ๐˜บ ๐˜ต๐˜ฉ๐˜ข๐˜ต ๐˜จ๐˜ฐ๐˜ฆ๐˜ด ๐˜ฃ๐˜ฆ๐˜บ๐˜ฐ๐˜ฏ๐˜ฅ ๐˜ข๐˜ด๐˜ด๐˜ถ๐˜ฎ๐˜ฑ๐˜ต๐˜ช๐˜ฐ๐˜ฏ๐˜ด.โ€

That clarity is essential. Whether itโ€™s decarbonizing energy sources, optimizing a production process, or reformulating a product line, change requires technical insight and careful design.

When quick wins are possibleโ€”such as shifting energy sources in countries with clean gridsโ€”they are implemented. But most change takes time, commitment, and collaboration.

The Financial Risk of Inaction

One of the most underappreciated aspects of the sustainability conversation is financial risk.

Doing nothing, Didier argues, will ultimately cost far more than taking action. Insurance premiums are rising in response to extreme weather events. Supply chains are vulnerable to resource shocks. In many cases, large corporations are already passing sustainability expectations down the value chain to their suppliers.

โ€œMany companies underestimate how much this will affect their bottom line,โ€ Didier says. โ€œNot just from regulation or investor pressure, but from real economic losses caused by environmental instability.โ€

Studies consistently show that a one-degree rise in global temperature could shave trillions off global GDP. Insurance claims from natural disasters are escalating. In some regions, sectors are becoming uninsurable altogether.

โ€œSustainability isnโ€™t just about ethicsโ€”itโ€™s about resilience.โ€

What Clients Say

Companies that work with H2D often highlight three things: the reliability of the insights, the collaborative way of working, and the sense of possibility the process creates.

โ€œWe bring optimism, not just analysis,โ€ Didier says. โ€œSustainability can feel overwhelming. But when clients see the results of their effortsโ€”and that thereโ€™s a path forwardโ€”they become engaged and energised.โ€

He adds, โ€œSome even tell us itโ€™s fun to work with us. And in this line of work, thatโ€™s not something to take for granted.โ€

Looking ahead

The industry is already shifting. Larger players are making sustainability a strategic priority, and the ripple effects are being felt across the value chain. H2D is helping accelerate that changeโ€”by bringing deep sector knowledge, scientific rigour, and economic practicality to the table.
