Hopefully an electric popemobile will be in the near future.
Also, for further reading for those interested in the pope's environmental concerns, check out this article from Dr. Jeff Mirus at CatholicCulture.org. The Green Pope's Dilemma:
... The right view of environmentalism both derives from and nourishes a proper vision of the human person. Pope Benedict made precisely this point in his great social encyclical, Caritas in Veritate. In the most general terms, his argument is as follows:Read the whole article.
The environment is God's gift to everyone, and in our use of it we have a responsibility towards the poor, towards future generations and towards humanity as a whole. When nature, including the human being, is viewed as the result of mere chance or evolutionary determinism, our sense of responsibility wanes. In nature, the believer recognizes the wonderful result of God's creative activity, which we may use responsibly to satisfy our legitimate needs, material or otherwise, while respecting the intrinsic balance of creation. If this vision is lost, we end up either considering nature an untouchable taboo or, on the contrary, abusing it. Neither attitude is consonant with the Christian vision of nature as the fruit of God's creation. (48)Thus the Pope stresses that we must guard against two errors:
Nature is greater than man: The neo-pantheistic attitude which finds a kind of salvation in nature is misguided because the human person has a supernatural destiny which nature is destined to help him to achieve.
Nature is raw material to be manipulated: Nature “is a wondrous work of the Creator containing a ‘grammar’ which sets forth ends and criteria for its wise use, not its reckless exploitation.” Without this understanding, we do violence to all of nature, including the nature of man himself.
But these two mistakes are culturally systemic. Therefore, the dilemma faced by Pope Benedict—who is commonly nicknamed the “green” pope for his interest in environmental stewardship—is how to communicate a constructive attitude toward both man and nature without having every environmental discussion co-opted either by the pantheists or the technocrats.
