Final answer:
PG Autos genuinely implements environmental measures in product and process improvement, which is indicative of green marketing, as opposed to greenwashing where companies only claim to be eco-friendly without substantial actions.
Step-by-step explanation:
PG Autos introduces new technology in its cars to improve their mileage and reduce carbon emissions, alongside improving its production facilities to reduce its own carbon footprint. This direct implementation of environmental measures rather than solely using advertising to appear eco-friendly indicates that PG Autos engages in green marketing. Green marketing refers to the practice of developing and promoting products and processes that are environmentally sustainable. Companies like PG Autos are displaying commitment to environmental goals by making their production processes greener and improving the environmental performance of their products. This is a key distinction from greenwashing, where a company may falsely give the impression of environmental responsibility through marketing while not taking substantive action.
