THREE East Yorkshire businesses have been recognised for their work to limit their environmental impact.
East Riding College, Humber Energy and Environmental Strategies Ltd have all received awards from Investors in the Environment.
All three have introduced new methods to reduce their energy consumption and make their businesses more sustainable.
East Riding College received the highest-level green award after joining the scheme last summer.
It was singled out for reducing its water use by 25 per cent and making 12 per cent gas and electricity savings.
The judges were also impressed with the college's move to have all of its food waste from the canteen collected for anaerobic digestion – a process used as a source for renewable energy.
The college's work towards the green award has been spearheaded by facilities manager Elaine Hall.
She said: "This award shows the level of commitment among students and staff to reducing our carbon footprint and having a positive impact on the environment and we are really proud to have achieved this award so soon into our membership.
"Our accreditation is proof that by taking a good look at the way an organisation works and committing to change, you can reduce your costs and boost your green credentials at the same time."
Humber Energy, a Cottingham business that supplies renewable technologies and infrared heating, was presented with a silver award after reducing its water use by 40 per cent.
Joanne Jenkinson, director at Humber Energy, said: "We're so proud to have achieved this award.
"It shows the level of commitment we have to reducing our carbon footprint and our impact on the environment.
"With a bit of hard work, you can reduce your costs and boost your green credentials at the same time."
Environmental Strategies, an environmental consultancy also based in Cottingham, received a silver award for its green achievements, including reducing its gas and electric.
Helen Wheeler-Osman, projects director at Environmental Strategies, said: "We feel proud to have achieved the silver level and more determined to go for a green award next year.
"The Investors in the Environment Awards are a great way for local companies to celebrate success in environmental management, as well as saving business costs.
"Being part of the scheme is important to Environmental Strategies as it enables us to demonstrate our own environmental credentials and adds value to the company as we grow and develop."
The Investors in the Environment scheme has seen a surge in members, including Hull City Council and Yorkshire Water, since its launch last summer.
It is managed and delivered by Yorkshire Energy Partnership and aims to help businesses in Yorkshire become more sustainable and competitive.
Emma Davies, senior project co-ordinator at Investors in the Environment, said: "We really applaud the work of all our accredited members and we hope more businesses will join.
"It's the fastest growing environmental scheme in our region for all the right reasons; immediate cost savings, attracting new customers and, most importantly, reducing a business's environmental impact."
