Final answer:
The partnership between Pearl Jam and UPS resulted in less pollution, more efficiency, and a switch from trucks to rail transportation.
Step-by-step explanation:
The correct answer is d) all of the above. When Pearl Jam partnered with UPS to develop a more environmentally friendly way to move the band's equipment, it resulted in less pollution, more efficiency, and a switch from trucks to rail transportation. By using rail, which is a more fuel-efficient mode of transport than trucks, the partnership helped minimize the environmental impact of moving the band's equipment.
The commitment to environmental sustainability by Pearl Jam through this initiative showcases how businesses and bands can contribute positively to mitigating climate change while still managing the practical aspects of their operations such as transporting band's equipment.
