Climate change will harm both current and future generations by limiting their access to a safe and prosperous world. For this reason, stopping climate change can be viewed as an ethical duty for current generations to not profoundly damage the prospects of future generations[1]. Concepts of ‘justice’ are also debated intensely within international climate change negotiations, as the question of how to distribute responsibilities for tackling climate change is in many ways about deciding what is ‘fair’ based on individual countries’ circumstances, historical role in creating emissions and how vulnerable they are to climate change impacts.
The fact that future generations will be exposed to more severe impacts of climate change - but are not able to participate in decision-making today about how to limit and avoid those future impacts – can be viewed as a question of intergenerational justice[2]. This is the notion that as our present choices have the power to influence the options and possibilities available to future generations, we are obliged to consider the future impact of these choices.
A failure to decrease emissions of greenhouse gases today would mean future generations have no choice but to face severe and harmful climate impacts in the future. Young people across the world have protested this unfair distribution through global school strikes. Religious writings, such as from the Pope and Islamic leaders, have also pointed out that as humans are stewards of the Earth, we are responsible for protecting it as our common home for both current and future generations[3],[4].
In addition, international climate negotiations have taken into account the need for fairness between developing and developed countries in acting on climate change. The Paris Agreement states that its Parties are guided by “the principle of equity and common but differentiated responsibilities and respective capabilities, in the light of different national circumstances”. It also recognises “the specific needs and special circumstances of developing country Parties, especially those that are particularly vulnerable to the adverse effects of climate change”[5].
Deciding on a fair distribution of responsibility has been contentious in climate negotiations. Some countries, like the UK, have made a major contribution to global emissions since the start of the industrial revolution, while others, such as India, have only recently become major emitters. This difference creates a strong sense of injustice in developing nations, if they believe that they are being asked to make the same contributions to cutting emissions as countries with a larger historical responsibility for emissions; and which are also richer because of economic development and growth that led to these emissions[6].
Going beyond historical responsibility, the idea of ‘capability’ is another way to determine a fair distribution of action between countries. This approach suggests the most financially or technologically capable countries should be responsible for acting most urgently to reduce emissions. This gives less capable countries a reduced responsibility for immediately lowering emissions, and is another reason some suggest it is fair for industrialised countries to lead efforts to tackle climate change.
Both the UK’s large historical responsibility for causing climate change and its strong ability to act - as a wealthy, developed nation - are among the reasons why the Committee on Climate Change suggested it was fair for the UK to reach net zero emissions of greenhouse gases by 2050[7].
