Correct answer: (C) 45 — The reduction needed is 45 percent, so the answer is 45.
Explanation
★The reduction needed is 45 percent, so the answer is 45.
★The IPCC set out what is needed to keep warming to 1.5 degrees Celsius.
★This limit is measured against pre-industrial temperature levels.
★To reach it, global greenhouse gas emissions must fall sharply.
★The IPCC indicates a cut of about 45 percent by the year 2030.
★The other figures do not match this indication.
★So the answer is 45.
