EHS – Environment and Regional Development Consulting, Lda results from a strategic repositioning, including a well succeeded internationalization of EHS – Consultores em Ambiente e Segurança set up back in 2004 to provide services in the fields of Environment and Environmental Safety. For the different Environmental domains – use of water, air emissions, energy production and consumption, waste and noise, or, from a broader perspective, the different natural environment components, the human populations and the economical activity, we privilege an integrated approach, supported on a cost-benefit rational, that maximises the sustainability of the solutions, including those concerning Regional Development.
