TED: How we can curb climate change by spending two percent more on everything | Jens Burchardt

The video discusses the significant climate impact of steel production, which accounts for over 5% of man-made emissions. It highlights the technical and economic challenges of producing low-carbon steel, such as carbon capture and the use of hydrogen. The video argues that a small increase in consumer spending, around 1-2%, on carbon-neutral products can significantly reduce emissions. It emphasizes the role of consumer choices in driving climate action and suggests that the cost of carbon-neutral products is relatively low compared to their environmental benefits.

What is the main reason coal is significant in the context of climate change?

• It is a renewable energy source.

• It is used in steel production, contributing to emissions.

• It is the cheapest form of energy.

• It is not used in industrial processes.

What is one technical solution mentioned for producing low-carbon steel?

• Increasing the use of coal.

• Switching to low-carbon hydrogen processes.

• Reducing the size of steel furnaces.

• Using solar panels in steel plants.

Why is it economically challenging for steel companies to reduce emissions?

• They already use renewable energy.

• They have no competition.

• They operate in a commodity business with low margins.

• They have high profit margins.

Which sector is NOT mentioned as part of the 'hard to avoid sectors club'?

• Cement

• Textiles

• Chemicals

• Aviation

How much could the cost of a car increase if made from carbon-neutral materials?

• By 10%

• By 20%

• By 50%

• By 2%

What is the potential consumer reaction to a 2% price increase for carbon-neutral products?

• Consumers might be willing to pay the extra cost.

• Consumers will not notice the change.

• Consumers will refuse to buy.

• Consumers will demand a 10% decrease.

What percentage of global emissions can be impacted by consumer purchasing decisions?

• Almost 50%

• Almost 10%

• Almost 25%

• Almost 75%

What is the estimated cost increase for a carbon-neutral smartphone?

• €3

• €3000

• €30

• €300

What is a major challenge in understanding supply chain emissions?

• It is not necessary.

• It is unbelievably cumbersome.

• It is very straightforward.

• It is already well understood.

What is the main argument for spending 1-2% more on products?

• It will significantly increase product quality.

• It will help reduce global emissions.

• It will decrease production costs.

• It will eliminate all emissions.
