Green liberalism
Green Liberalism is a term used to refer to liberals who have incorporated green concerns into their ideology.
Green Liberalism values the planet very highly; it is considered very important that the planet be passed down to the next generation unharmed. Green Liberalism accepts that the natural world is a system in a state of flux, and does not seek to conserve the natural world as it is. However, it does seek to minimise the damage done by the human species on the natural world, and to aid the regeneration of damaged areas.
In economic issues, Green Liberals take a position somewhere between classical liberalism and new liberalism: They favor slightly less government involvement than the new liberals, but far more than the classical liberals.
Green Liberalism is now the dominant form of liberalism in some countries, most importantly Germany, as well as, to a lesser extent, in the United Kingdom. The brand of green politics advocated by most Green Parties is not Green Liberalism, however. It could be described as "Green Social Democracy".
Historian Conrad Russell, a British Liberal Democrat member of the House of Lords, dedicated a chapter of his book "The intelligent person's guide to liberalism" to the subject of Green Liberalism.
