But a new report published yesterday has revealed the regulator has missed some of its own sustainability targets.
Despite achieving four out of six environmental targets for 2012-13, the agency performed less well against its greenhouse gas emission targets.
The body has grand plans to reduce its emissions by 42% by 2020, linked to a baseline dating back to 2007. Although its latest emissions are 10.1% lower than the baseline year, its total carbon dioxide output rose by 2.4% during 2012/13. It also missed on its target to reduce travel emissions.
Sepa said the figures were broadly in line with its internal greenhouse gas plan. However, new targets have now been set for the next financial year.
Stirling-based Sepa's chief executive James Curran said: "As Scotland's environmental regulator, we understand we must set a strong example to members of the public and businesses throughout the country."
