Engineers' Confidence in Economy Wanes
ATLANTA—Confidence in the economy among U.S. engineering professionals decreased slightly in the first quarter of 2013, according to a new survey conducted by Harris Interactive on behalf of Randstad Engineering. Slightly more than a quarter (26%) of engineering professionals responded that they feel the economy is getting stronger. That is a considerable drop from the 34% who responded with confidence in the fourth quarter of 2012. However, 73% of engineers said they are not likely to lose their jobs over the next 12 months.

China Agrees to Phase Out HCFCs
MONTREAL—China has agreed to accept $385 million from Multilateral Fund for the Implementation of the Montreal Protocol (MLF) to eliminate industrial production of HCFCs by 2030. China is the world's largest producer of HCFCs, accounting for 92% of the total HCFC production of developing countries. Developed nations contribute to the MLF to pay "incremental costs" for developing countries to transition from HCFCs to environment-friendly substitutes. According to a statement by the government of China, the phaseout will prevent the emission of more than 4.3 million metric tonnes of HCFCs.
