There is a growing movement advocating for using closed border policies as a tool for solving the climate crisis. On this view, which I call the green border argument, fighting climate change requires drastic reductions in the global population and/or per capita greenhouse gas (GHG) emissions. However, immigration into high-income countries—particularly from low-income countries—increases per capita emissions while leaving the population untouched. Therefore, the green border theorist argues, we should limit entry into high-income countries. I explain why this is a (...) mistake and why the political left should embrace a pro climate and pro migrant politic. -/- First, the argument significantly overstates the impact of immigration on global GHG emissions. Second, the progressive green border argument is normatively incoherent. It advocates for closing borders and eliminating poverty and other rights violations in sending countries. However, given the relationship between emissions and income, this argument would require rejecting all poverty reduction strategies—a conclusion the progressive theorist wants to avoid. Third, the argument is counterproductive. An open border politic better promotes climate justice. A key reason is that high-income countries perceive immigration to be one of the most serious short- and medium- term costs of climate change. Whereas closure allows them to avoid this “cost,” open borders would force them to eliminate push factors, incentivizing global adaptation and mitigation strategies. Moreover, a closed border politic creates divisions between those affected, undermining cross-border solidarity and contributing to the perception that environmentalism is a white, middle-class movement.

The overarching goal of environmentalism as a political movement is the creation of sustainable societies that share resources fairly among people, and among people and other species. The core objectives of environmental philosophy should include articulating the ideals and principles of such just and generous sustainability, arguing for them among academics and in the public sphere, and working out their implications in particular areas of our environmental decision-making. That means challenging the goodness of endless economic growth and helping other environmental (...) thinkers specify plausible and appealing alternatives to the economic status quo. It means ending our craven failure to honestly address population issues. It means committing to living according to our own environmental ideals. Interestingly, the mainstream philosophical tradition has some important, underutilized resources that, combined with new andcreative thinking, can help us achieve these goals and keep ethical philosophy relevant to meeting the challenges of the 21st century.

Even though anthropogenic climate change is largely caused by industrialized nations, its burden is distributed unevenly with poor developing countries suffering the most. A common response to livelihood insecurities and destruction is migration. Using Peter Singer's ‘historical principle’, this paper argues that a morally just evaluation requires taking causality between climate change and migration under consideration. The historical principle is employed to emphasize shortcomings in commonly made philosophical arguments to oppose immigration. The article concludes that none of these arguments is (...) able to override the moral responsibility of industrialized countries to compensate for harms that their actions have caused. (shrink)

The future of environmental ethics will be what environmental ethicists make of it. Since the field encompasses widely divergent philosophical orientations, talents, particular interests, and intuitions about the way forward, that future will be pluralistic. I believe this to be a good thing. But it is also helpful to step back from time to time, reflect on where we want to go, and ask whether we are leaving any essential tasks unaddressed.I take the overarching goal of environmentalism as a political (...) movement to be the creation of ecologically sustainable societies, which both preserve the biosphere's regenerative capacities and share resources fairly among people, among people and other species, and between ..
