World must urgently take actions to reduce roughly a further quarter off predicted 2030 global greenhouse emissions to have any chance of minimizing dangerous climate change, says just released UNEP's annual Emissions Gap report. The report states that 2030 emissions are expected to reach 54 to 56 gigatonnes of CO2 equivalent – far above the level of 42 needed for limiting global warming to 2°C this century.
The report presents an assessment of the technologies and opportunities for further cuts required, including through non-state actors, energy efficiency acceleration and crossover with the sustainable development goals. Investments in energy efficiency have increased by 6 per cent to US$221 billion in 2015, reflecting significant efforts already happening around the world. According to estimates, an investment of between 20 and 100 US$ per tonne of carbon dioxide can realise energy efficiency emissions reduction potential of around 12 gigatonnes in buildings, industry and transport sectors by 2030.
