London's best sustainable bars
These bars all commit to environmentally and socially sustainable initiatives in their day-to-day service

Ryan Chetiyawardana, aka Mr Lyan, is so dedicated to offsetting food waste that he uses absolutely no fresh ingredients at Hoxton bar White Lyan – which marked a first for the global bartending industry when it opened. Instead, all the cocktails are made in-house, pre-bottled in batches and infused with ingredients that would ordinarily be used as garnishes. Oh, and there's no ice, either. What remains is a pared-down bar, with no back-bar full of bottles – just a functional, sparse room and drinks with enough flavour and character to elevate the bar to an award-winning level. Which we think is pretty cool.
LCW signature serve: Tennessee Nitro Martini, with Jack Daniel's Old No.7, Sandow's cold brew coffee and Mr Lyan cola.

Jamie Oliver's bar and restaurant has been renowned as a great eating and drinking destination for years, but there's another reason to love it that you might not even be aware of: it's completely non-profit, and used to run an apprentice programme recruiting 18 young people aged 18-25 to train them to the highest standard and give them new opportunities.
LCW signature serve: Strawberries & Cream, made with Langley's gin, Dolin dry vermouth, fresh strawberries, tarragon, chai, coconut water and clarified milk.

The Happenstance's bar and restaurant group Drake & Morgan's commitment to local and seasonal sourcing as well as a focus on sustainable and ethical trading won it a Sustainable Small Group of the Year nomination at this year's SRA awards.
LCW signature serve: Dos Veleros, made with Havana Club 7YO rum, fresh lime juice, ginger and homemade vanilla syrup.

One of London's new entrants into the World's 50 Best Bars list, Oriole is a glitzy bar where the drinks list is inspired by the exploration era. The bar team grow garnishes for their top-end cocktails – including golden thyme, chocolate mint and pineapple sage – under a hydroponic light right at the bar. Now that's a way to cut down on waste – not to mention food miles.
LCW signature serve: The Duke of Savoy, with Hennessy cognac, calvados, hazelnut sugar, quince cordial and lemongrass juice.

As well as sourcing top-quality meat at its restaurant from leading butcher Ginger Pig, Hawksmoor's bars and restaurants also work closely on fundraising events with food charity Action Against Hunger, which works to provide self-sufficiency and combat famine in disaster zones around the world.
LCW signature serve: Honey Melba – Evan Williams bourbon, Amaro Cia Ciaro, strawberry Aperol and citric acid.
