Manifest for a sustainable economic recovery

More than 240 personalities from politics, civil society and business, including the founder of SUST4IN, Marcio Viegas, have come together to demand the Commission for Social and Economic Reconstruction recovery plans based on sustainability criteria.

The response to Covid-19 must be bold, green and social

The recovery response to the Covid-19 pandemic is an unintended opportunity to shift the world to a greener economy, but the social emergency and future social demands cannot be ignored, argues Marcio Viegas.

Our purpose

The key purpose of SUST4IN is to push and support our clients on their sustainability journeys through high quality, innovative and independent information, consulting, training and assurance solutions.

We firmly believe that sustainability, namely the Sustainable Development Goals and the ambitious, urgent and just transition, is good business for all because it is the right thing to do, plus the risks of not acting and, more important, the enormous opportunities it brings to us.
