Meeting the climate challenge: core elements of an effective response to climate change
Achievable gains in energy efficiency, renewable energy, forest conservation, and sustainable land use worldwide could achieve up to 75 percent of needed global emissions reductions in 2020 at a net savings of $14 billion. These actions, along with additional investments in climate adaptation, would deliver a wide range of economic, security, and environmental benefits in developed and developing countries. Greater international support for these core elements would make an immediate contribution to solving the climate problem and help to achieve a new international climate agreement.
