In a press briefing at COP24, Navigant discussed how government climate action doesn’t yet change projected warming
If all governments achieve their climate targets by 2100, the world will see 3.0˚C of warming, double the 1.5˚C limit agreed upon in the Paris Agreement three years ago, according to the Climate Action Tracker (CAT). The CAT is an independent science-based assessment that tracks the emission commitments and actions of countries around the world.
“We are seeing a stirring of new climate policies in the real world: if this were extended and scaled up, these combined efforts could actually begin to bend the emissions curve,” said Yvonne Deng, associate director leading the project at Navigant.
The findings show that while government policies are currently behind initial pledges forecasting a warming of 3.3°C, if they do implement the planned policies, warming could be limited to 3.0°C by 2100.
Climate actions have been mixed throughout 2018, where countries including Norway and Costa Rica are moving forward with electrifying transportation and renewable energy, while China’s emissions increased for the second year in a row.
