Individual action on climate change describes the personal choices that everyone can make to reduce the greenhouse gas emissions of their lifestyles and catalyze climate action. These actions can focus directly on how choices create emissions, such as reducing consumption of meat or flying, or can be more focus on inviting political action on climate or creating greater awareness how society can become more green. Excessive consumption is one of the most significant contributors to climate change and other environmental issue than population increase.
