Canada signs Convention on Climate Change at Rio’s Earth Summit

The Story

The 1992 Earth Summit in Rio de Janeiro is almost over, and Prime Minister Brian Mulroney is promising that Canada will do its part to clean up the planet. As one of more than 100 world leaders attending this United Nations-organized conference, Mulroney signs the Convention on Climate Change -- an agreement to reduce greenhouse gas emissions. But as we see in this 1992 news clip, while some applaud Mulroney's actions, others say his promises don't go far enough.

Did You know?

• A total of 155 nations signed the convention — known in full as the United Nations Framework Convention on Climate Change (UNFCCC) — in Rio in 1992. Although the treaty was an agreement to reduce greenhouse gas emission, it was a fairly general document without many specific terms. Built into the treaty, however, was a provision to add more specific amendments or "protocols" to the agreement. The now well-known Kyoto Protocol of 1997 was an update to the UNFCCC.
