I am Alberto Monzonís Comes. Companies bring me in when a senior sustainability seat cannot wait, or when sustainability has just become a real corporate responsibility and the function must be built while it delivers. I join from within, take ownership of the mandate, and leave behind a function that stands on its own.
A senior sustainability role is open, it needs to be operating now, and the permanent search is not producing anyone. I step into the seat, take ownership of reporting, governance and delivery, and keep the function moving until the right permanent hire lands.
Sustainability has just become a real corporate responsibility, often triggered by a listing, an IPO or new regulation. Many projects open at once, and the company needs senior knowledge during the build. The mandate is not meant to be permanent: the team should stand on its own afterwards.
New to interim? What an interim sustainability manager is, and when to bring one in.
Most external sustainability help fails for a reason that has nothing to do with technical quality. The outsider never learns how the company actually works: the internal politics, the culture, the informal relationships, what has to happen for a decision to land. So the technical work is fine, and nothing moves.
My method is the opposite. I go in to learn the organisation first: who the people are, where the power sits, how things get done there. Then I build sustainability in a way that works for that company, creating connections for it inside the existing hierarchy, improving governance and coordination between teams, and using the expertise the company already has instead of importing it.
What I offer is not a deliverable. It is clarity, alignment and execution: sustainability becoming reliable and integrated, so the company keeps producing credible results after I leave. That is why mandates are measured in months rather than weeks, and why part of every mandate happens on site. Presence is not a concession; it is how the work gets done.
Five years leading non-financial audits at PwC are why a report I run can stand up to a CSRD audit cycle.
A consulting career at PwC is why I can build governance and strategy where none exists yet.
Mentoring senior executives at ESADE is why I build a team’s own capability rather than becoming a dependency.
Time inside organisations is why I know where plans stall, and what it takes to move them.
Interim work is judged by what a company keeps after you leave, and by whether they ask you to stay longer.
A newly listed beauty and fashion group had to deliver its first CSRD-aligned report, with responsibilities fragmented across Communication, Finance and Sustainability, on a compressed timeline. I created a C-level steering group, designed the CSRD reporting structure and delivered the report. Then came a second one, to a higher standard, with the publication date brought forward by three weeks.
Read the Puig caseA top-three global manufacturer of recycled plastic pallets was preparing for its IPO with a newly promoted Sustainability Director, an intern, and no governance, strategy or systems. I built the sustainability function from the ground up: operating model, first strategy, priorities and KPIs, training for executives and the team. EcoVadis Gold for the first time; later Platinum.

I am not there to produce appearances. If the results are not real, the report should not say they are.
I will not be the person sustainability is delegated to and forgotten. If the function is meant to sit in an isolated office with no route into the business, it is the wrong mandate.
I work where there is genuine willingness to do the work properly, and where sustainability is allowed to be part of the business.
Three months. In practice, mandates have run twelve to eighteen.
Hybrid: substantially remote, with a meaningful on-site presence. Being physically inside the organisation is essential to how I work.

On enquiry.
I have worked in corporate sustainability since 2015, and independently since 2021. My training ground was PwC, where I spent five years leading non-financial audits and advising on sustainability, CSR and climate. Since going independent I have completed the Corporate Sustainability Management programme at Yale School of Management and the CFA Institute Certificate in ESG Investing. My first discipline was a BSc in Environmental Sciences from the University of Valencia.
Across audit, consulting, mentoring and interim mandates I have worked with more than thirty companies, in sectors from luxury, beauty and pharma to retail, food and beverage, banking, energy and industrial packaging.
Tell me about the situation: the seat that is open, the function being built, the deadline in view. I read and answer everything personally.
