Challenging climate change: energy efficiency perspective

Transcription

1 Challenging climate change: energy efficiency perspective Valdis Bisters Director of Climate and Renewable Energy Department Ministry of the Environment, Republic of Latvia

2 Main points of the presentation Climate change challenge - shift of paradigma Carbon flows and stabilization opportunities Co-benefits of climate change mitigation Energy efficiency and climate change mitigation measures Leverage for low carbon economy

4 Emission projections

5 Efficiency and Conservation transport buildings industry Efforts needed to stabilize GHG emissions power lifestyle

6 Pacala & Socolow s Stabilization Wedges The blue area indicates a level of emission that would result in a stabilization of greenhouse gas levels within an acceptable 550 ppm * The green area indicates projected growth in greenhouse gas emissions over the next fifty years Each wedge in the green area represents 1 gigaton of carbon that must be removed from these growth projections Source: Pacala, S. and R. Socolow. "Stabilization Wedges: Solving the Climate Problem for the Next 50 Years with Current Technologies." Science, 13 Aug 2004, p * Note: Others place the maximum acceptable level much lower, at 440 ppm
