The guardians of the region's stately homes and protected countryside have given a pat on the back to their 'green' champions.
The National Trust held its first ever environmental champions event - which saw teams and individuals honoured for a range of achievements - including energy reduction and wise use of water.
Winners of the 10 categories attended an awards event at Anglesey Abbey, near Cambridge, where the red carpet was swapped for a lush green carpet of artificial grass.
The trust's environmental practices adviser for the East of England, Miranda Campbell, said: 'The awards are a fantastic way to shine a light on and celebrate the amazing, but sometimes overlooked, work that our properties do to improve their environmental performance and will hopefully inspire other properties and our supporters with their ideas and enthusiasm.'
The trust is the largest conservation charity in Europe and is committed to reducing its energy consumption by 20pc by 2020.
Winners were given a certificate and wood-turned plate.
Norfolk winners were:
Green Team of the Year – Sheringham Park - Has reduced electricity use by 25pc since 2009 baseline, uses rainwater to flush to the toilets, and biomass heating, fuelled by the park's trees, has ended the use of oil at ten visitor centre.
Best Energy Reduction - Oxburgh Hall - cut its energy use by a 35pc since 2013, through LED lighting, changing catering practices, and more efficient heating system which is also better for conserving the 15th-century Hall.
Wise Use of Water Award - Blickling - restoration of a Victorian water management system now feeds the Walled Garden. Natural management of the River Bure has reduced sediment reaching the lake and the risk of the hall flooding.
Green Kitchen of the Year – Felbrigg Hall - the new Squire's Pantry tearoom has LED lights and new low consumption electric heaters. Food waste goes to compost. Coffee grinds are used in the Walled Garden as slug repellent!
Meter Manager of the Year – Richard Lee, Blickling - an unsung hero who for 20 years has ensured the estate's 61 meters are read on time - even arranging his time off around readings. He has had to battle with shoulder-height stinging nettles, curious cows and had to move frogs to get the numbers.
Special Achievement Award – North Norfolk Coast team - for its work with young people at the Brancaster residential learning centre, encouraging them - and more than 4000 schools - to reduce their impact on the natural environment, through recycling, energy use reduction and minimising food waste.
Other winners were:
The Acorn Award – Countryside Team at Wimpole near Cambridge.
Waste-not Winner, Dunwich Heath
Holiday Cottage Hero – Elizabeth and Don Headley, Dunwich Heath, Suffolk
