Which statements are true and which statements are not true valuation of climate change occurring in the future? Do not motivate! a. A low discount rate means that we will set a high carbon dioxide tax today. b. If an environmental problem arises in a year and then is valued at SEK 500 billion This means a valuation today of approximately SEK 455 billion on the discount rate is 10 percent. c. If the discount rate is zero, there will be an environmental problem that arises in the future and which is then valued at 1000 billion to be valued at 1000 billion today. d. If an environmental problem that arises in one year is valued at SEK 200 billion at the time when the environmental problem arises and is valued at 150 billion today, must the discount rate used is 25 percent. e.
