A decade ago, calorie counts on menus changed how people made food choices. Not by limiting options – by adding information. Carbon labelling is the next step. The science exists. The methodology is available. What’s been missing is a clear, scalable way to put it in front of diners.
Most sustainability conversations in hospitality focus on energy, water, or waste. Those are important. But food itself — what’s on the plate, where it came from, how it was grown — accounts for a disproportionate share of the sector’s emissions. In many cases, ingredient sourcing alone contributes more to a property’s carbon footprint than its operations.
The hospitality sector has struggled to act on this partly because the data has been too hard to obtain, and partly because there hasn’t been a usable language for communicating it to guests.
Calorie labelling was once the same kind of problem. Industry resisted. The data was messy. Standardisation took years. Then it became normal — in menus, on packaging, on apps. Consumers didn’t have to become nutritionists. They just needed a simple signal.
The same logic applies to climate impact.
Telling a diner a dish emits 2.4 kg CO₂e doesn’t help them decide. Most people don’t have a reference point. But ‘aligned with a 1.5°C future’ or ‘climate heavy’ is something they can act on,the way they act on red/amber/green nutrition scores.
What a rigorous labelling framework actually looks like
Olive Gaea’s climate-aligned labelling methodology covers the full farm-to-fork footprint: agricultural sourcing, ingredient composition, transportation, preparation energy, and operational waste. Each dish is assessed against IPCC AR6 climate pathways (The Intergovernmental Panel on Climate Change’s Sixth Assessment Report — the most comprehensive scientific review of climate change to date.) and the global carbon budget ((the total amount of CO₂ the world can still emit while limiting warming to 1.5°C above pre-industrial levels) ), benchmarked on a per-100g serving basis for consistency.
The output is a three-tier label:
- Climate-Friendly — aligned with a 1.5°C future (the temperature limit set by the Paris Agreement under the UNFCCC to avoid the most severe impacts of climate change, measured relative to pre-industrial levels)
- Climate Moderate — aligned with ~2.2°C
- Climate Heavy — aligned with 3.5°C+
These aren’t decorative. They’re derived from Product Carbon Footprint assessments, FAO Agrifood Emissions datasets, and dietary benchmarks normalised by per-capita allocation. They can be adapted to brand guidelines without compromising methodological integrity.
The pilot, in practice
We ran a pilot of this framework with one of the luxury hotel chains in the world, across 16 properties – a useful test of how the methodology holds up at scale and across diverse menus. The work involved a farm-to-fork assessment of menu items, identification of high-impact ingredients and procurement hotspots, and the development of consumer-facing labels aligned with ASCI guidelines consumer-facing labels aligned with established advertising and communication standards (including ASCI -Advertising Standards Council of India, where the pilot was conducted).
The exercise surfaced more than emissions data. It revealed procurement inefficiencies, ingredient substitution opportunities, and menu design decisions that could reduce both cost and carbon simultaneously. For operations and sustainability teams, that kind of intelligence has practical value well beyond what goes on the label.

Why this matters now
Scope 3 reporting requirements are expanding. Hospitality groups operating across multiple geographies are facing investor, regulator, and partner expectations that increasingly extend to supply chain and food-related emissions. The menu is part of the emissions story — and increasingly, it will need to be part of the disclosure.
Beyond compliance, there’s a simpler point: consumers are making more sustainability-informed choices. An 80% willingness-to-pay premium for sustainable products across markets isn’t a niche signal. Hospitality groups that give diners the information to make climate-informed choices aren’t just reporting better — they’re building relevance.
What happens at scale
The value of climate labelling isn’t in a single menu on a single property. It’s in the pattern that emerges when you run the methodology across hundreds of dishes, multiple cuisines, and diverse supply chains. You start to see which ingredient categories carry the most impact, which procurement relationships create the most risk, and where menu redesign can deliver the most efficient emissions reduction.
That’s what turns a label into an operational tool.
On 25 June, as part of London Climate Action Week, Olive Gaea is hosting an online webinar on menu-level climate-aligned labelling – what a rigorous, scalable rating system could mean for the F&B sector, and what the pilot revealed about putting it into practice.
