英文：

Environmental investment refers to the investment of funds aimed at protecting the environment, improving environmental quality, and preventing environmental pollution. With the increasingly serious environmental issues globally, environmental investment has become the common responsibility and obligation of governments and enterprises.

The scope of environmental investment is very broad, including the research and promotion of environmental protection technology, the construction of energy-saving and emission-reducing projects, the development and utilization of green energy, and the protection and restoration of the ecological environment. These investments are not only beneficial for protecting the environment and improving environmental quality, but also promote economic development and social progress.

For enterprises, environmental investment is a social responsibility and obligation, as well as a necessary means for sustainable development. Through environmental investment, enterprises can reduce environmental pollution and resource waste, improve resource utilization efficiency, reduce production costs, and enhance market competitiveness. At the same time, environmental investment can also bring enterprises a good social image and reputation, increasing consumers' trust and recognition of enterprises.

Governments play an important role in environmental investment. Governments can encourage enterprises and individuals to invest in the environment through policy and financial support, promoting the development of environmental protection industries. At the same time, governments can also strengthen the management and supervision of environmental protection through regulation and punishment to ensure the implementation and effectiveness of environmental investment.

Overall, environmental investment is a valuable public welfare undertaking that requires the joint efforts of governments, enterprises, and individuals. Only through continuous environmental investment and innovation can we achieve the goals of environmental protection and sustainable development.
