The review will examine current activity across the organisation and assess programmes against criteria including environmental outcomes, operational effectiveness, statutory requirements and value for money.
Councillor Morgan Brobyn, Suffolk County Council's Cabinet Member for Food, Waste and Rural Affairs, said:
"Climate change is a subject that people feel strongly about, and residents rightly expect the council to help communities respond to challenges such as flooding and extreme weather.
"But our responsibility is not to maintain declarations for their own sake. Our responsibility is to deliver practical outcomes that protect Suffolk's environment and support our communities.
"Whether that's improving flood resilience, enhancing biodiversity, reducing waste or making sure taxpayers' money is spent effectively, those are the things that will make the biggest difference on the ground.
"I was pleased that some members from across the chamber were able to find common ground on the importance of practical environmental stewardship, and I was happy to support the Conservative group’s amendment which further reinforced that principle within the motion.
"The choice at today’s council meeting was not between caring about the environment and not caring about the environment. It was about ensuring that environmental stewardship is practical, effective and focused on outcomes. That is the approach we will be taking as we move forward."
Further details of the review, including timescales and reporting arrangements, will be announced in due course.
