The USA's market for environmental consultancy services (ECSs) accounts for 44% of the global total, a new report from The Business Research Company shows.

Because of the USA's dominance, the knock-on effect for the global market of any slowing or decline in the USA could be severe. As the Trump Administration's repealing of the country's Clean Power Plan and the weakening of its Environmental Protection Agency is expected to restrain the growth and even possibly lead to a decline of the ECS market in the USA, the risk to the industry is substantial.
