Energy Policy Scenarios to 2050
10.1.7. 2020: Credible commitments and slower emissions growth
Measures might include long-term carbon tax credits with a specific focus on promoting investment; specific schemes of support for low-carbon; power-generation alternatives; and stronger renewable energy portfolio standards facilitated by intelligent electricity-delivery technology. In addition, broad commercial introduction of advanced clean coal technology, particularly in rapidly industrialising nations such as China and India. However, there are questions about China's and/or India's willingness to be bound to limits on emissions in the framework of any post-Kyoto Protocol . In the transportation sector, growth in emissions should be restrained by a combination of measures - technical approaches via vehicle efficiency, hybrid vehicles, and biofuels, along with non-technical measures aimed at changing behaviour to lower carbon-transport modes via taxation, regulation, or other means. Achieving and maintaining a significantly greater global investment in technology development and deployment is equally important and lays down the essential basis for realising subsequent sustainable carbon reductions.
