Human Nature: Catholic Thought and the Sciences/Climate Change

The relation of Catholic doctrine to climate change is expressed in the Compendium of the Social Doctrine of the Church:


 * Programs of economic development must carefully consider “the need to respect the integrity and the cycles of nature” because natural resources are limited and some are not renewable. The present rhythm of exploitation is seriously compromising the availability of some natural resources for both the present and the future. Solutions to the ecological problem require that economic activity respect the environment to a greater degree, reconciling the needs of economic development with those of environmental protection. Every economic activity making use of natural resources must also be concerned with safeguarding the environment and should foresee the costs involved, which are “an essential element of the actual cost of economic activity”. In this context, one considers relations between human activity and climate change which, given their extreme complexity, must be opportunely and constantly monitored at the scientific, political and juridical, national and international levels. The climate is a good that must be protected and reminds consumers and those engaged in industrial activity to develop a greater sense of responsibility for their behaviour.


 * An economy respectful of the environment will not have the maximization of profits as its only objective, because environmental protection cannot be assured solely on the basis of financial calculations of costs and benefits. The environment is one of those goods that cannot be adequately safeguarded or promoted by market forces. Every country, in particular developed countries, must be aware of the urgent obligation to reconsider the way that natural goods are being used.  Seeking innovative ways to reduce the environmental impact of production and consumption of goods should be effectively encouraged.


 * Particular attention will have to be reserved for the complex issues surrounding energy resources. Non-renewable resources, which highly-industrialized and recently-industrialized countries draw from, must be put at the service of all humanity. From a moral perspective based on equity and intergenerational solidarity, it will also be necessary to continue, through the contribution of the scientific community, to identify new sources of energy, develop alternative sources and increase the security levels of nuclear energy. The use of energy, in the context of its relationship to development and the environment, calls for the political responsibility of States, the international community and economic actors. Such responsibility must be illuminated and guided by continual reference to the universal common good.
