Traffic-Light Taxation of Food

Clear information. Consistent standards. A healthier food market.

Open for scrutiny — Manifesto 1.1

Proposal 36 would establish a mandatory national Green, Amber and Red nutritional classification for qualifying food products sold in the United Kingdom. The system would help consumers compare products consistently, encourage manufacturers to improve nutritional quality and provide a transparent foundation for later proposals on food taxation, healthy-food subsidies and reformulation.

Published Manifesto 1.1 policy. The sections below set out the proposal as published. Questions and challenges are open questions, not settled answers.

1. The core idea

Manifesto 1.1 proposes a mandatory national traffic-light framework for qualifying food products sold in the United Kingdom. Each product would receive a standardised Green, Amber or Red nutritional classification so consumers can understand its relative nutritional quality quickly and consistently.

The framework would provide the common classification needed for later proposals on unhealthy-food taxation, healthy-food subsidies and manufacturer reformulation.

This proposal does not invent the thresholds, tax rates or qualifying scope that the source leaves undefined. These details must be properly developed, evidenced and scrutinised before implementation.

Core commitment

Make nutritional quality clear before changing prices or taxation.

2. What the classification would consider

  • Sugar and salt: Measure key nutrients associated with diet-related harm using published, evidence-based thresholds.
  • Saturated and trans fats: Reflect both fat quantity and type, including stronger treatment where the health risks are greater.
  • Overall composition: Assess the whole product rather than relying on one positive or negative nutrient in isolation.
  • Degree of processing: Include processing where evidence shows that it materially affects nutritional quality or health.
  • Fibre and protein: Recognise beneficial nutritional characteristics without allowing them to disguise excessive harms.
  • Other relevant factors: Permit transparent updates as evidence, products and public-health understanding develop.

3. A simple public signal

The public-facing system should be easy to recognise, while the technical method beneath it must be independently governed, evidence-led and open to challenge.

  • Green: Products meeting the strongest defined nutritional criteria. Green would indicate relatively healthier nutritional quality within the national framework.
  • Amber: Products between the Green and Red thresholds. Amber would communicate moderation and allow proportionate policy treatment.
  • Red: Products meeting defined high-risk nutritional criteria. Red would indicate the strongest concern, not a ban on purchase.

4. Rules the framework would need

  • Qualifying scope: Define which packaged, prepared, imported, hospitality and specialist products must be classified.
  • Nutritional thresholds: Publish the evidence, calculations, category adjustments and treatment of serving size.
  • Classification authority: Give a competent independent body responsibility for standards, decisions and updates.
  • Transparency: Make classifications, methods, evidence, conflicts and changes publicly accessible.
  • Appeals and corrections: Allow errors and disputed classifications to be reviewed without weakening enforcement.
  • Consistent display: Use clear placement, size, wording and accessibility rules across physical stores and online sales.

Open for scrutiny

Scope, thresholds, exemptions and governance must be specified before implementation.

5. Consumer understanding and industry incentives

  • Quick comparison: Let shoppers compare products consistently without requiring specialist nutritional knowledge.
  • Accessible design: Use legible labels, plain language and formats suitable for people with colour-vision deficiency and for digital shopping.
  • Reformulation: Give manufacturers a clear incentive to reduce harmful ingredients and improve overall nutritional quality.
  • Reclassification: Allow genuinely improved products to move category once they meet the published criteria.
  • Public education: Explain what each colour means, what it does not mean and how it fits within an overall diet.
  • Ongoing evaluation: Track understanding, purchasing, reformulation, health effects, avoidance and unintended consequences.

6. Safeguards against distortion

  • Masking: Prevent a single added nutrient from masking excessive sugar, salt or harmful fats.
  • Product categories: Use appropriate product categories where direct comparison would otherwise mislead consumers.
  • Portions: Review the treatment of portion sizes, concentrates and products marketed as multiple servings.
  • Small producers: Protect small producers from unnecessary complexity without creating loopholes in consumer protection.
  • Existing labelling: Coordinate with existing UK nutrition labelling and avoid contradictory signals on the same product.

Principle

Clear choices for consumers. Better incentives for the food industry.

7. Questions for scrutiny

This proposal should be tested with nutrition scientists, public-health specialists, consumer groups, people affected by diet-related ill health, food manufacturers, farmers, retailers, hospitality businesses, schools, local authorities, trading standards, economists and the devolved administrations.

  1. 01Which food products should qualify, and which exemptions — if any — are justified?
  2. 02Which body should set, apply and periodically revise the classification rules?
  3. 03How should sugar, salt, saturated fat, trans fats, fibre, protein and processing be weighted?
  4. 04Should thresholds vary by food category, portion size or intended use, and how can complexity be controlled?
  5. 05How should fresh, unpackaged, restaurant, takeaway and imported foods be treated?
  6. 06How can labels remain accessible to people with colour-vision deficiency, limited literacy or visual impairment?
  7. 07What evidence and consumer testing should be required before the categories become mandatory?
  8. 08How should manufacturers challenge errors while preventing delay or tactical appeals?
  9. 09How should reclassification work when a product is reformulated or new evidence emerges?
  10. 10What enforcement, inspection and penalties should apply to missing, misleading or false classifications?
  11. 11How should the UK framework interact with existing front-of-pack labels and devolved responsibilities?
  12. 12Which outcomes should trigger revision: understanding, purchasing, reformulation, health or market effects?

Core purpose

Give every qualifying food product one clear, consistent nutritional signal.

8. The proposed direction

Proposal 36 would establish a mandatory national Green, Amber and Red system for qualifying food products.

Classification would reflect sugar, salt, saturated and trans fats, overall composition, processing, fibre, protein and other relevant nutritional characteristics.

The system would help consumers compare products and create a transparent foundation for later food-tax, subsidy and reformulation policies.

Before implementation, government must specify the qualifying scope, nutritional thresholds, authority, exemptions, display rules, appeals, enforcement and evaluation plan.

Source basis: Manifesto 1.1, Part XXII, Policy 40, “Traffic-Light Taxation of Food”, Major Promise 36 — A National Food Traffic-Light System. The source restores the mandatory Green/Amber/Red framework and nutritional factors. Qualifying scope, thresholds, authority and exemptions are not specified and remain open for scrutiny.
