Which of the following is an example of mitigation strategy?

Improving energy efficiency to reduce emissions is a clear example of a mitigation strategy because it directly addresses the root cause of climate change—excess greenhouse gas emissions. By enhancing how efficiently energy is used in homes, businesses, and transportation, less energy is required to achieve the same outcomes. This reduction in energy consumption translates to lower fossil fuel use, leading to decreased emissions of carbon dioxide and other greenhouse gases.

Mitigation strategies aim to curb the extent of climate change by preventing or reducing the sources of these gases. Improving energy efficiency not only helps in reducing emissions but can also decrease dependency on fossil fuels, promote sustainable practices, and ultimately lead to a reduction in the overall ecological footprint of a society.

While building seawalls, planting trees, and creating more public transport options are important for adaptation and sustainability efforts, they address either protection from climate impacts or enhancement of ecosystem services rather than directly mitigating the causes of climate change through emission reductions.
