As we’ve mentioned a few times on this very site, in order for the United States to agree to any treaty at the Copenhagen Conference on Climate Change, said treaty has to fall within the limits of what the United States unilaterally agrees to implement in combating climate change on the domestic front. As it turns out, many other countries have the same stipulation going into the conference in December. This, of course, makes any agreement harder to reach, as each country is going to have different goals.

But there’s good news! Great news! The Environmental News Service reports that 100 legislators from around the world have just agreed to try and get their home countries to pass climate change legislation ahead of the conference in order to have similar laws in place prior to the treaty negotiations in order to make them go smoother! Sweet deal.

Legislators from 16 of the world’s major economies and most major political parties have agreed on key guiding principles to enact climate change legislation in their home countries that will drive the move to a global low carbon economy. Meeting this weekend, the lawmakers agreed to act right now in their own legislative bodies, even before the key UN climate deal in Copenhagen, now just six weeks away.

The principles - covering building and appliance standards, renewable energy, vehicle fuel and efficiency standards, as well as forestry - were proposed by U.S. Congressman Edward Markey and Chinese Congressman Chairman Wang Guangtao.

The legislators were actually meeting in Copenhagen for the International’s Copenhagen Legislator’s Forum held by the Global Legislators Organisation for a Balanced Environment (GLOBE) when the agreement was reached. If these politicians can go back to their home countries and get their policies through, international climate change legislation could really take off.

At the GLOBE meeting, legislators said the principles they agreed could achieve 70 percent of the emissions cuts needed by 2020 to limit the global average temperature rise to two degrees Celsius, the level most scientists believe will prevent the worst consequences of climate change.

That’s not all, though! The legislators also agreed to a more comprehensive emissions monitoring and verification system, longer-term emissions targets, forest protection, and even $100 billion per year from public and private interests to give to developing nations to fight climate change. This is all great–if this works, the Copenhagen Conference just got a huge, huge boost.
