Answer:
Yes, global-level agreements about the environment can work in practice. These agreements are typically negotiated between countries and involve commitments for taking specific actions to reduce environmental damage or increase sustainability. Examples of global-level agreements include the Paris Agreement, which is a commitment from signatory countries to reduce greenhouse gas emissions, and the Kyoto Protocol, which set targets for reducing emissions of certain gases. These agreements are implemented through a variety of means, including carbon taxes, emissions trading schemes, and commitments to renewable energy sources. The success of these agreements depends on the commitment of participating countries to uphold their obligations and the willingness of other nations to join the agreement.
