The Kerala State Pollution Control Board (KSPCB) has published its Revised Categorisation List as of 03.08.2026. The KSPCB industry categorisation list 2026 places 739 industrial, service, infrastructure and environmental-service activities across five categories: Red, Orange, Green, Blue and White. The most visible entries dated 3 August 2026 concern hotels, restaurants, standalone banquet or marriage halls, waste-battery collection centres and non-leather footwear manufacturing.
The category is not a label to select by business name alone. Room count, seating capacity, event area, fuel, boiler and genset type, wastewater generation, treatment method, production capacity and specific operations can move similar businesses into different categories. A hotel using cleaner or gaseous fuel may be placed below an otherwise comparable hotel, but only where the exact description and listed conditions are satisfied.
This update explains what the source expressly records, what the wider CPCB framework says, and which practical checks businesses should complete. The source does not state a separate effective date, transition period, compliance deadline, fee, or penalty. Those details must not be inferred from the words 'as on 03.08.2026'.

If a business is setting up or running an activity in Kerala that falls under pollution-control rules, KSPCB consent may be required. CTE is taken before the project starts, while CTO is required before operations begin, depending on whether the Water Act, Air Act or both apply. The approval process also covers other environmental permissions related to water, air and waste.
The classification of industries was updated nationally by CPCB in 2025. The Pollution Index (PI) is worked out using water, air and industrial waste parameters. Industries with a score of 80 or more are Red, those between 55 and below 80 are Orange, 25 to below 55 are Green, and anything below 25 is White. Blue is separate from these bands, and covers essential environmental services dealing with domestic, or household pollution.
CPCB explains that classification can guide consent management, inspection frequency, siting, pollution control planning and progressive environmental management. It also recognises that cleaner technologies, cleaner fuel, operating scale and segregated processes may justify different sub-categories. This is why the same broad activity can appear more than once in the Kerala list.
Legal distinction: The category gives a business an idea of which compliance route may apply, but it is not the whole approval process. Depending on the activity, the business may still need consent conditions, waste authorisations, environmental clearance, local permissions or compliance with siting rules. Any later directions issued by CPCB or KSPCB may also need to be followed.
| Category | Kerala Entries | CPCB Reference | How to Read It |
| Red | 145 | PI 80 or more under the CPCB framework | Highest pollution potential; the Kerala list includes major chemical, metallurgical, waste-processing, infrastructure and high-threshold service activities. |
| Orange | 205 | PI 55 to below 80 | Moderate-to-high potential; many activities appear here where capacity, wastewater, fuel or process increases pollution load. |
| Green | 206 | PI 25 to below 55 | Lower pollution potential, often linked to cleaner fuel, smaller scale, dry processing or reduced wastewater generation. |
| Blue | 12 | Separate essential environmental services category | Kerala lists MSW facilities, waste-to-energy, biomining, C&D waste processing, sewage treatment and specified CBG activities. |
| White | 171 | PI below 25 | Activities with very low pollution potential, but only within the stated process, capacity, fuel, wastewater and equipment limits. |
The revised list covers factories, services, healthcare, hospitality, infrastructure and waste management activities in Kerala. It can apply to new units as well as existing businesses making changes to capacity, equipment, fuel or processes.
A category should not be picked just because a keyword matches. Businesses need to check the full activity description and remarks, along with factors such as scale, fuel, wastewater, and waste generation. The following factors repeatedly control category selection:
The list does not create a blanket exemption for an entire trade. For instance, a dry assembling activity can appear in White, while related wet processing, surface treatment or emission-generating work appears in a higher category.
The list covers industries, services, healthcare, hospitality, infrastructure, and waste management activities in Kerala. It applies to both new, and existing units making operational changes.
The category depends on the actual activity, not just a matching keyword. Check the activity description and remarks before deciding.
| Activity Group | Category Coverage | What the List Records |
| Hotels, motels and resorts | Red, Orange, Green and White | Room-count bands and cleaner/gaseous-fuel variants; conditions cover gensets, boilers, grease traps and wastewater management. |
| Restaurants, dhabas and eateries | Orange, Green and White | Category determined by seating capacity: above 200, 101-200, and up to 100 seats. |
| Standalone banquet/marriage halls | Orange, Green and White | Category determined by congregation area: above 2,500 sqm, above 1,000 to 2,500 sqm, and up to 1,000 sqm. |
| Waste-battery collection centres | Green | Must follow CPCB guidelines for collection, handling, storage and transportation of waste batteries, as amended from time to time. |
| Non-leather footwear manufacturing | White | Limited to dry process and no boiler. |
| Existing White-list entries | White | Rows 1-84 and row 86 also show 03-Aug-26 alongside earlier dates. The consolidated data does not identify the exact amendment to each row. |
The following sectors have specific classifications in the revised list and are worth checking closely before deciding which category applies.
Hotels, Motels and Resorts
For hotels, motels and resorts, the category depends on the number of rooms and the type of kitchen fuel used. So, the room count alone does not decide the category.
| Hotel Profile | Category | Express Qualification/Condition |
| Above 300 rooms | Red | No cleaner-fuel qualifier stated in this Red entry. |
| Above 300 rooms using cleaner/gaseous kitchen fuel | Orange | CPCB IV+ or 100% gas genset; electric or gas boiler; oil and grease trap; standalone STP. |
| 101-300 rooms | Orange | No separate conditions printed against this row. |
| 21-100 rooms | Orange | No cleaner-fuel qualifier stated in this Orange entry. |
| 21-100 rooms using cleaner/gaseous kitchen fuel | Green | Compliant/gas genset; electric/gas boiler; grease trap. More than 50 rooms require standalone STP; 21-50 rooms follow CPHEEO wastewater methods. |
| Up to 20 rooms | Green | No separate conditions printed against this row. |
| Up to 20 rooms using cleaner/gaseous kitchen fuel | White | The row states the cleaner/gaseous-fuel condition; no separate remark is printed against row 170. |
A hotel should therefore document the actual kitchen fuel, boiler arrangement, genset specifications, room count and wastewater route. Merely planning to use a cleaner fuel is not the same as satisfying every condition attached to the lower category.
Restaurants, Dhabas and Eateries
| Seating Capacity | Category | Source Position |
| More than 200 seats | Orange | Listed at Orange serial number 160. |
| 101 to 200 seats | Green | Listed at Green serial number 136. |
| Up to 100 seats | White | Listed at White serial number 169; the remarks placement across pages is ambiguous and requires careful confirmation. |
The remarks for the White-category restaurant mention a few conditions, including compliant gensets, an oil and grease trap at the kitchen outlet, and proper wastewater management as per the CPHEEO Manual. Since the remarks continue from the banquet-hall entry on the previous page, it is not fully clear which conditions apply to each category. Businesses should get written confirmation from KSPCB before relying on the White classification.
Standalone Banquet and Marriage Halls
| Congregation Area | Category | Express Qualification/Condition |
| More than 2,500 sqm | Orange | Area means the space earmarked for congregation of guests, as shown in the building plan, fire NOC, local-authority permission or venue layout. |
| More than 1,000 sqm and up to 2,500 sqm | Green | Oil and grease trap at the kitchen outlet. |
| Up to 1,000 sqm | White | Conditions begin in the remarks column and continue across the page break; exact allocation should be confirmed with KSPCB. |
The floor area should be checked from the official building or venue records rather than estimated from marketing material. The same method should be followed for the lower categories as well. If the area is unclear, it is better to check with KSPCB.
Waste-Battery Collection Centres and Non-Leather Footwear
| Decision Factor | Why It Matters | Evidence to Review |
| Cleaner/gaseous fuel | Can move certain hotel profiles to a lower category when every linked condition is met. | Fuel invoices/specification, kitchen equipment and boiler details |
| Genset standard | Higher-capacity or non-compliant gensets can alter pollution potential. CPCB also states that a White or Green sector with a higher-category genset may be treated in the higher category. | Nameplate capacity, fuel type, emission standard and maintenance records |
| Wastewater generation | Several White entries state or imply movement to Green when wastewater is generated; many other categories use KLD/MLD thresholds. | Water balance, discharge route, STP/sewer records and sampling plan |
| Production capacity | Limits such as tonnes per day, metric tonnes per month or kilograms per day are part of the category description. | Installed capacity, consented capacity and actual production data |
| Dry versus wet process | A dry, assembling-only or physical-mixing activity may be White while wet processing or chemical treatment is higher. | Process flow diagram, machinery list, raw materials and cleaning method |
| Surface treatment/painting | Pickling, electroplating, heat treatment, spray painting and similar operations frequently move fabrication activities upward. | Operation-wise layout and outsourced-process contracts |
The revised list is useful for checking the current classifications, but a few points need to be read carefully:
The revised list may change how a business applies for consent and what pollution-control measures or documents it needs. What actually changes will depend on the activity, its existing consent and the KSPCB requirements that apply to it.
| Stakeholder | Immediate Impact | Likely Operational/Cost Effect | Priority Concern |
| Hotels and resorts | Re-map category by room count, kitchen fuel and controls. | Possible changes to STP, genset, boiler and grease-trap planning. | Do not rely on room count alone. |
| Restaurants and eateries | Confirm the licensed seating capacity band. | Wastewater and kitchen controls may require review. | Clarify the White-entry remarks. |
| Banquet/marriage halls | Measure congregation area from official plans or permissions. | Grease trap, genset and wastewater arrangements may affect readiness. | Resolve page-break ambiguity in writing. |
| Waste-battery collection centres | Map the activity to Green and the CPCB guideline condition. | Storage, handling and transport controls may need a gap assessment. | Category does not replace separate waste duties. |
| Manufacturers/assemblers | Check every process qualifier and capacity threshold. | A new boiler, wet step, surface treatment or wastewater stream can raise the category. | Maintain an accurate process inventory. |
| MSMEs and startups | Select the category before committing to site and machinery. | Early design decisions can prevent rework in applications and pollution controls. | Use the exact row, not a broad trade name. |
The operational and cost effects above are reasonable business implications, not confirmed financial consequences stated by KSPCB. The source provides no fee table or cost estimate.
Businesses should treat category mapping as a controlled compliance exercise. The steps below help connect the source list with a clear and defensible decision without assuming requirements that are not actually stated.
| Priority | Action | Responsible Team | Relevant Timing | Expected Outcome |
| Immediate | Prepare a complete activity profile: products/services, capacity, room/seat/area thresholds, process steps, fuel, boilers, gensets, water balance, wastewater and waste streams. | Operzations, engineering and EHS | Before category selection | Accurate factual baseline |
| Immediate | Match the profile to the exact KSPCB category row, serial number, circular reference and remarks. | EHS/legal | Before filing or renewal | Traceable category rationale |
| High | Compare the mapped category with the current CTE/CTO and any pending application. | EHS/legal | As soon as practical | Identify mismatch or amendment need |
| High | Seek written KSPCB clarification where two rows overlap or the page-break remarks affect the chosen category. | Authorised signatory/legal | Before relying on the lower category | Documented regulatory position |
| High | Close source-based control gaps, including applicable genset, boiler, grease-trap, STP, wastewater or battery-handling conditions. | Engineering/operations/EHS | Before commissioning or relevant filing | Controls aligned with the selected row |
| Ongoing | Update process-flow diagrams, machinery and capacity records whenever operations change. | Operations/EHS | At each modification | Early reclassification check |
| Ongoing | Monitor later KSPCB circulars and the official revised-list page. | Compliance/legal | Periodic review and before renewal | Current category mapping |
Corpseed can support businesses that need a defensible category assessment or consent strategy under the revised Kerala list. The work should begin with the actual process and pollution profile, not a pre-selected category.
A pollution control consent consultant can help align the factual profile, category rationale and application record before submission. Corpseed does not guarantee approval or a fixed processing time; the final category and consent decision remain with the competent authority.
Call to action: Hotels, restaurants, banquet halls, manufacturers and waste-battery collection centres can request a category and consent-readiness review before filing, renewal or operational modification. Corpseed's environmental compliance services can identify the exact KSPCB row, unresolved conditions and evidence gaps that need attention.
