Environmental reporting
Sustainable business practices
Partners for climate action
Corporations are increasingly required to report on their environmental impact, including greenhouse gas emissions, water use, and waste generation
02 Environmental protection measures
Energy conservation and emission reduction
Reduce energy consumption
Improve energy efficiency in buildings, transportation, and industrial processes
National policies and regulations
Carbon taxes
Many countries have implemented carbon taxes, which charge a fee for greenhouse gas emissions, to resource businesses and individuals to reduce their emissions
Enhance the reduction of waste by designing products to be more durable and recyclable
Implement extended product responsibility

Global Warming
1.What is global warming
Global warming is the gradual rise in the Earth's temperature caused by high levels of carbon dioxide and other gases in the atmosphere.
Other species may go extinct as rainfall patterns change throughout the world
So we must take effective measures to solve this problem
What should we do?
Secondly, they should make laws that limit the amount of greenhouse gases that companies can emit. Private companies should be rewarded for following these laws. They should also be punished for creating pollution.
Effects on Wildlife
Polar Bears
Require pack ice to live Might eventually go extinct in the wild
Sea turtles
Breed on the same islands as their birth Could go extinct on some islands as beaches are flooded
