Environment & Climate Change

"Chinese President Xi Jinping reaffirmed at the global climate change conference in Paris that China pledged to achieve peak carbon dioxide emissions by around 2030, and to get around 20 percent of its primary energy from non-fossil sources by 2030. In 2014, China’s non-fossil energy consumption accounted for 11.2 percent of total energy use—hydro power was 8 percent, nuclear power was about 1 percent, and non-hydro renewable energy was around 2 percent—which is very close to the target of 11.4 percent set for 2015. Still, coal supplied the majority (66 percent) of China's total energy consumption in 2014, and oil accounted for about 18 percent of the energy mix. Natural gas, at 5 percent, still accounted for a relatively small share. To double the share of non-fossil sources by 2030, what role can nuclear power play?"

In this Q&A with The Tehran Times, Matthew Bunn is interviewed about the  “painful compromises” that Iran and the 5+1 countries will need to make if a final deal is to be struck on Iran's nuclear program.

"Biotechnology offers Africa a wider range of economic opportunities than the Green Revolution did. It is already being used to improve food production and establish or revive cotton production. Its economic impact is therefore likely to go well beyond the farm sector to include industrial development."

Dramatic growth in nuclear energy would be required for nuclear power to provide a significant part of the carbon-free energy the world is likely to need in the 21st century, or a major part in meeting other energy challenges. This would require increased support from governments, utilities, and publics around the world. Achieving that support is likely to require improved economics and major progress toward resolving issues of nuclear safety, proliferation-resistance, and nuclear waste management. This is likely to require both research, development, and demonstration (RD&D) of improved technologies and new policy approaches.

This week, when the leaders of the G8 industrial democracies gather in France, their meeting will include discussions of what steps must be taken to strengthen global nuclear safety and global nuclear security  in the aftermath of the tragedy at Fukushima. The Belfer Center's Matthew Bunn and Olli Heinonen suggest new actions the world community should take in five key areas in order to prevent another Fukushima.

"Security, by contrast, is something most people in the nuclear industry might get a half-hour briefing on once a year. If you have intelligent adversaries, it wouldn't be a surprise to have the main power for the cooling and the backup power both fail — the adversaries would plan to make sure that happened. This transforms all the probabilities we rely on for safety. The global nuclear safety regime needs strengthening — but it is far stronger than the global nuclear security regime. And that applies to theft of nuclear material as well as sabotage of facilities."

African agriculture is at a crossroads. Persistent food shortages are now being compounded by new threats arising from climate change. But Africa also has three major opportunities that can help transform its agriculture to be a force for economic growth. First, advances in science, technology, and engineering worldwide offer Africa new tools needed to promote sustainable agriculture. Second, efforts to create regional markets will provide new incentives for agricultural production and trade. Third, a new generation of African leaders is helping the continent focus on long-term economic transformation.

In an Op-Ed in The Bulletin of the Atomic Scientists, Matthew Bunn and Martin B. Malin argue that a reinvigorated IAEA and new approaches to cooperation on nuclear safety, security, and nonproliferation are required for nuclear energy to make a significant contribution to mitigating climate change without creating undue risks.
