Renewable Energy


1 Wimpole Street has a well-earned reputation as a gold-standard meeting venue, but it’s also setting the standard in sustainability. As well as having a recycling programme that covers all areas of waste, the venue uses 100% renewable energy and has low energy light bulbs and a Building Management System to regulate and monitor temperature and energy usage.

With in-house virtual and hybrid event tech and a knowledgeable team, the venue is well-equipped to encourage video conferencing and streaming of meetings so that remote delegates can participate without having to travel long distances. Where notepads are required for meetings, 1 Wimpole Street provide FSC-certified paper and encourages less to be used.

Food Sustainability Policy

Upcycling Emphasis

CCT Venues have a clear mission to become a leader in the meetings industry when it comes to operating in an environmentally friendly. Their venues have been winning green awards since 2008 and it’s not hard to see why with initiatives such as refurbishing furniture rather than replacing it, having motion sensitive lighting, donating unneeded electronics to charities, and removing all single-use plastic from service areas at its Smithfield location.

The venue also has a food sustainability policy, as well as measures to reduce food waste – any unused food is composted or turned into biofuel! They have also implemented a Sustainable Purchasing Policy, which gives preference to environmentally-sound products, and require all suppliers to fill out a questionnaire on their sustainability measures before contracting them.

Upcycling Emphasis

Energy Saving

Wallacespace’s meeting venues are bright and quirky, which matches their attitude to making green choices. Lots of their furniture is upcycled, second-hand, or made by their talented team, giving their meeting spaces a totally unique and interesting aesthetic. Their ‘Wallywood’ initiative has seen around 1420 trees planted across the English countryside, while they use surplus ‘wonky’ veg in their catering, stopping these from going to waste.

And they’re even greener behind the scenes. None of their waste goes to landfill – if can’t be recycled, it’s taken to a waste-to-energy facility where remnants are burnt, producing electricity and heat which is used to power homes. Rooms have their own air-conditioning to save on heating and cooling the whole venue, and lights are energy efficient – it’s enough to make other venues green with envy!

Water Saving

Local Ingredients

As well as being a top choice for sophisticated meetings, 30 Euston Square is on a sustainability crusade, educating its staff on sustainability at the venue through special training schemes, and implementing solutions like rainwater harvesting for use in toilets. The venue’s catering team also use ingredients sourced locally – so locally, in fact, that it includes their own herb garden on their roof top terrace – and converts reclaimed cooking oil to biodiesel.

The venue is also looking to the future and planning the installation of solar panels and waterless urinals, as well as – and this has got us really intrigued – exploring the possibility of installing grass roofs. We thought their sleek meeting spaces and roof terrace were enough of a selling point, but these plans have got us excited for a green future for meetings!
