Q & A

What environmental issues are associated with global maritime trade?

Global maritime trade contributes significantly to environmental hazards, including CO2 emissions from conventional cargo ships, which account for 2.9% of global greenhouse gas emissions.

How are sailing ships being utilized to address climate change?

Sailing ships, like the converted Schooner mentioned, utilize wind power for transporting goods, demonstrating an eco-friendly alternative to traditional shipping methods.

What challenges do small vineyards face due to climate change?

Vineyards are experiencing extreme droughts, leading to reduced grape yields, with some vineyards reporting a potential 50% decrease in production if conditions do not improve before harvest.

How does the shipping industry impact whale populations?

Loud engines from conventional ships disrupt whale communication, making it harder for them to find food and navigate, which threatens their survival.

What is the significance of using hybrid vessels in tourism?

Hybrid vessels, powered by both electric and gas, significantly lower emissions, making them a more sustainable option for whale watching and eco-tourism in sensitive environments like Norway.

What innovative technology is being tested to reduce fuel consumption in shipping?

The Flatner rotor, a technology that creates additional propulsion by using wind power, is being implemented on ships to decrease fuel usage and reduce CO2 emissions.

What is the potential of the new sailing ship Oceanbird set to launch in 2025?

Oceanbird is designed to be driven mainly by wing sails, aiming to cut CO2 emissions by up to 90%, representing a significant advancement in sustainable shipping technology.

What steps are being taken to ensure cleaner shipping practices in Norway?

Starting in 2026, Norway will only permit emission-free ships in its most beautiful fjords, setting a standard for cleaner tourism and maritime practices.

How do consumer choices affect environmental sustainability in shipping?

Encouraging consumers to choose sustainably produced goods and reduce excess purchases can help lower the environmental impact of shipping and promote more responsible consumption.

What is the role of young sailors and trainees on the sailing cargo ship?

Young sailors and trainees participate in learning and hands-on work aboard the ship, gaining experience in sustainable practices and contributing to eco-friendly transport of goods.
