TRM: Industry Emissions

=== PART OF TRANSPORT REWORK MOD ===

Industries pollute like what they are.

In the base game every processing industry emits the same pollution, so a brewery pollutes exactly like a steel mill, a farm with all its fields emits more than either, and an airport pollutes heavily before any aircraft lands. With this mod a steel mill emits 500, a brewery 60 and a forest about 45, and airports and warehouses emit a quarter of their base game pollution.

=== FEATURES ===

• Each industry type gets its own value. From steel mills, oil refineries and cement plants at the top down to food factories, forests and fishing grounds at the bottom. Idle, boosted and full-stock behavior stay as in the base game.
• Transport buildings emit less of their own. Airports, heliports and warehouses a quarter of their base game pollution and noise, airfields, helipads, road stations, harbors, depots and maintenance facilities half. Rail stations are unchanged. The build menu cards show the reduced values.
• The vehicles are not touched. Aircraft, trains, ships and road vehicles emit as before.
• Industries are never written to the save. Their values apply while the mod is active and change within a moment of loading.

=== SETTINGS ===

• Industry Emissions ("Base Game", "Rebalanced", default "Rebalanced"). In the base game every processing industry emits 250 pollution when producing. With "Rebalanced" each industry type has its own value: steel mills, oil refineries and cement plants 500, glass works and brickworks 250, breweries and printing presses 60, mines and quarries 160 to 180, a full farm about 90 and a forest about 45. Idle, boosted and full-stock behavior stay as in the base game, and the cement plant's noise is brought in line with the other factories. The game's Pollution Sensitivity setting still applies on top.
• Transport Building Emissions ("Base Game", "Rebalanced", default "Rebalanced"). In the base game an airport emits 400 to 480 pollution before any aircraft lands, a depot about a third of a factory and a large specialized warehouse a whole one, and their noise runs at one to four times a steel mill. With "Rebalanced" airports, heliports and warehouses emit a quarter of their base game pollution and noise, and airfields, helipads, road stations, harbors, depots and maintenance facilities half. Rail stations are unchanged, and the vehicles using the buildings emit as before. A building built while this is "Rebalanced" keeps its reduced values until it is rebuilt if the mod is removed.

=== INGAME EXAMPLES ===

• Steel mill, oil refinery, cement plant: 250 pollution in the base game, 500 with this mod.
• Chemical plant and paper mill: 350. Glass works, brickworks, tire factory: 250. Brewery, food factory, printing press: 60.
• Mines and quarries with all fields: 160 to 180. Farms: 90 to 120. Forest: about 45.
• Airport: a quarter of its base game pollution. Depot: half.

=== COMPATIBILITY ===

The mod replaces the emission update script of the game and cannot be combined with another mod that does the same. It is independent of vehicle and track emission mods and of "TRM: Emission Tolerance". Industries from other mods keep their own values. Industries are never written to the save, but a station, depot or warehouse built with the mod keeps its reduced value until it is rebuilt if the mod is removed. The game's Pollution Sensitivity setting still applies on top. Option changes take effect at the next load.
