“For every Red Carnation hotel to achieve EarthCheck Silver certification within 14 months is a significant achievement. What stands out is that this commitment has been embedded across the entire portfolio, rather than concentrated in a handful of flagship properties. That takes leadership, investment and, importantly, people on the ground who are prepared to measure performance and manage it every day. Results like this don’t happen by chance. Red Carnation put the time and resources in at every property, from London to Cape Town, and that shows.”

The short version

  • Red Carnation Hotels earned EarthCheck Silver across its entire portfolio in the UK, Ireland, Europe, and South Africa.
  • Eight properties across the collection achieved zero landfill waste.
  • The Oyster Box reduced water consumption by 58 per cent, while London's The Rubens at the Palace and Hotel 41 achieved emissions intensity of 3.29 kg/GN.

Red Carnation Hotels achieved EarthCheck Silver certification across its entire global portfolio after a 14-month process following Bronze status in 2025. Covering properties in the UK, Ireland, Continental Europe, and South Africa, the credential required passing independent on-site audits across 10 environmental and social performance areas. Operational measures delivered zero landfill waste across eight hotels alongside double-digit water reductions [1].

What does EarthCheck Silver certification require from hotel operators?

EarthCheck Silver status requires a hospitality operator to satisfy all operational performance standards evaluated across 10 specific performance areas during an independent, external on-site audit [1]. Boutique Hotel News reported that Red Carnation progressed to this tier over 14 months after securing EarthCheck Bronze status in 2025 [1]. The certification assesses operational footprints rather than paper policies alone [1].

Rather than confining compliance to corporate leadership, the group appointed dedicated on-site data managers and local coordinators at each individual property to measure metrics daily and monitor compliance [1]. As documented by Boutique Hotel News, EarthCheck founder and CEO Stewart Moore noted that the group directed time and capital across every site rather than limiting performance improvements to high-profile flagship properties [1].

Which operational performance metrics did individual properties achieve?

Individual hotels recorded notable reductions in water consumption, carbon intensity, and landfill disposal across different operating environments [1]. For example, The Oyster Box in South Africa reduced its water usage by 58 per cent, cutting its emissions intensity by nearly the same level [1]. The Lodge at Ashford Castle in Ireland reduced water consumption by 48 per cent [1].

In central London, The Rubens at the Palace and Hotel 41 generated the lowest emissions intensity in the global collection at 3.29 kg/GN [1]. Furthermore, Boutique Hotel News confirmed that eight properties across the group reached zero landfill waste [1].

How did the group manage data and property-level execution?

Operational execution relied on property-level data coordinators working alongside external technology and conservation partners [1]. Red Carnation integrated the food waste tracking platform Winnow into its kitchen operations, while also maintaining on-site kitchen gardens and beehives to curb waste generation and localize dining operations [1].

Michelle Devlin, vice president of sustainability at Red Carnation Hotels, stated in Boutique Hotel News that the company manages environmental impact by combining resource reduction with community and conservation efforts [1]. Group initiatives include partnerships with the environmental charity Hometree, prisoner rehabilitation organization The Clink Restaurant at HMP Brixton, and youth empowerment organizations based in Cape Town [1].

What regions does the portfolio-wide certification cover?

The Silver credential covers Red Carnation's operating footprint across four primary regional markets: the United Kingdom, Ireland, Continental Europe, and South Africa [1]. Stewart Moore emphasized in Boutique Hotel News that achieving verified benchmarks across an entire multinational collection required ground-level management to track daily resource data from London to Cape Town [1].
