Climate bond is a kind of investment that helps people fight climate change. When you buy a climate bond, you are giving money to people or organizations that are finding ways to fight climate change, like developing renewable energy sources or inventing new technologies to reduce pollution. This money helps both the people who are working on the solutions and the environment that we all share. The more people who buy climate bonds, the more money will be available for people fighting climate change, and the better our environment will be!
