About Tosca

Tosca is a Tribe of professionals who are pooling their knowledge, insights and experience in order to jointly  contribute to a more sustainable world. What connects and drives us is our effort to achieve wellbeing for all. We do this by assisting organisations in being a ‘force for good', that is to say acting ethically and with respect for society and the environment.

For us, sustainability is about long-term welfare. That is why long-term value creation is always our starting point. Organisations can achieve it by putting their stakeholders and society at large centre stage in their actions. Integrated thinking and focusing on the long term are essential in this.

We act as Change Agents focused on progress. We prefer big clients, but we are also happy to assist organisations who are just starting out in this process. We support and enable change by enhancing awareness, transferring knowledge and aligning with individual motives. We prefer to operate in co-creation with our clients because we believe that this will result in sustainable improvement and change, and will enhance the engagement of the entire organisation.

For us, sustainability is about long-term welfare.

Just one pebble in the pond can create a ripple

I am convinced that organisations can only be successful in the long term if on balance they are making a positive contribution to society. With my experience as an adviser, accountant, director and supervisor I want to contribute to the transition towards a sustainable society. Everybody can make their own contribution. No matter how small the pebble is that you throw in the pond, together we can make a giant wave.

Creating real impact together

By bringing together my background in marketing & strategy with sustainability I want to help organisations to make REAL impact on their way towards a green, open and inclusive economy.  I am convinced that companies can only be and remain successful if they look at all three pillars of sustainability: so not just the economic pillar, but certainly also the social dimension, and taking care of our planet.

Your CSR plan on one A4

Defining, implementing and communicating a sustainability policy together with a company: this is what I like to do! With a unique and personal story that you, as an employee of a company, can be proud of. With concrete goals and results. And beautifully designed. Preferably on 1 A4. This makes it clear to employees, customers and other stakeholders where you stand as an organization and where you want to go. That works very well, I know this from my 15 years of experience as a sustainability consultant.

Do not harm Do good

The motto I can identify with is 'Do not harm Do good'. Based on the essence that I like to see organizations realize positive impact, more than just managing 'less negative effects'. To achieve organization-wide improvement, I like to work in teams. And by asking the right questions, I support organizations in gaining insight and overview. I am looking for an instrument that fits the working method, business operations and the level of ambition. With my experience as a consultant and auditor, I ensure that the insights obtained are converted into plans and actions.

Positive change through focus and connection

Sustainable business stimulates positive change - for society and for a specific organization. For me, this always starts from focus on the most important (material) topics and a connection between people, organizations and knowledge. The connection between business goals and societal needs is the basis for an effective, sustainable strategy. That engages people to work together for sustable success.

Steering towards impact

Delivering sustainable performance requires more than just a financially healthy business model. The complete picture is broader, more complex, and challenges us to look with an open mind at why we do the things we do and how it can be improved, within the limits of the planet and with consideration for all stakeholders. And this is how you can steer towards impact. As a former Finance Director, I know how to manage for financial results. It is my passion to teach companies to look more broadly, to bring the right focus, and then to steer towards impact.

A proactive role for businesses in the sustainability transition

As an ESG advisor, I guide companies in developing and implementing sustainability strategies, ESG reporting, and solving ESG issues. My background as a procurement director has always given me a particular focus on the supply chain responsibilities of companies. Collaboration is an essential condition for corporate social responsibility. I am motivated to play a proactive role together with companies in the sustainability transition.
