(1) The exceedingly small but fully real effects of my greenhouse gas emissions
(2) A threshold phenomenon?
(3) Unilateral duties to reduce greenhouse gases or promotional duties?
My argument thus far can be summarized as follows: the greenhouse gases emitted by individuals have a small but fully real effect in that they increase the exposure of vulnerable people to the risk of serious suffering from climate change harms, now and in the future. These individual emissions are sufficient to do so and also necessarily have this effect. From this follows that individuals have a unilateral duty to reduce the emission of greenhouse gases that they can reasonably avoid. Promotional duties are very much necessary as well, but cannot substitute this unilateral duty to reduce emissions.
In this post, I will give an indication of how individuals can reduce emissions that are clearly avoidable on the individual level. We cannot expect people to reduce emissions that are unavoidable on the individual level, since these are necessary to meet their basic rights, but I will argue that households and individuals emit much more greenhouse gases than is often believed, especially in the developed world. A significant share of these emissions can be avoided, including a share of those resulting from residential energy use, personal transportation and the consumption of meat and dairy products (1)
