G8 statement: Reaction in quotes

A round-up of reaction to the announcement by G8 world leaders at a summit in Japan that they will aim to set a global target of cutting carbon emissions by at least 50% by 2050 in an effort to tackle global warming.

Dan Price, President Bush's assistant for international economic affairs

In our view, and in the view of the leaders in the room, this represents substantial progress from last year.

Jose Manuel Barroso, European Commission president
This is a strong signal to citizens around the world.

Marthinus van Schalkwyk, South African environment minister

While the statement may appear as a movement forward, we are concerned that it may, in effect, be a regression from what is required to make a meaningful contribution to meeting the challenges of climate change. As it is expressed in the G8 statement, the long-term goal is an empty slogan without substance.

WWF, environmental group

If after a year's work all you have is a "shared vision" instead of "seriously considering", it's pretty pathetic.

Tearfund, charity

The G8 are crawling forward on emissions cuts at a time when giant leaps and bounds are needed. To do little more than restate last year's G8 commitment to halve emissions by 2050 is a very disappointing outcome, demonstrating a lack of leadership and vision.

Daniel Mittler, Greenpeace international

Instead of action, the world got flowery words. The Texas oilman has once again prevented the G8 from undergoing the energy revolution it needs. Bush is a lame duck, so who cares what he thinks about 2050?
