Metropolitan OperaThe Metropolitan Opera (commonly known as the Met) is an American opera company based in New York City, currently resident at the Metropolitan Opera House at Lincoln Center, situated on the Upper West Side of Manhattan. The company is operated by the non-profit Metropolitan Opera Association, with Peter Gelb as general manager. As of 2018, the company's current music director is Yannick Nézet-Séguin. The Met was founded in 1883 as an alternative to the previously established Academy of Music opera house and debuted the same year in a new building on 39th and Broadway (now known as the "Old Met").
French operaFrench opera is both the art of opera in France and opera in the French language. It is one of Europe's most important operatic traditions, containing works by composers of the stature of Rameau, Berlioz, Gounod, Bizet, Massenet, Debussy, Ravel, Poulenc and Messiaen. Many foreign-born composers have played a part in the French tradition, including Lully, Gluck, Salieri, Cherubini, Spontini, Meyerbeer, Rossini, Donizetti, Verdi and Offenbach.
Comic operaComic opera, sometimes known as light opera, is a sung dramatic work of a light or comic nature, usually with a happy ending and often including spoken dialogue. Forms of comic opera first developed in late 17th-century Italy. By the 1730s, a new operatic genre, opera buffa, emerged as an alternative to opera seria. It quickly made its way to France, where it became opéra comique, and eventually, in the following century, French operetta, with Jacques Offenbach as its most accomplished practitioner.
MailThe mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing. Postal authorities often have functions aside from transporting letters.

Program evaluationProgram evaluation is a systematic method for collecting, analyzing, and using information to answer questions about projects, policies and programs, particularly about their effectiveness and efficiency. In both the public sector and private sector, as well as the voluntary sector, stakeholders might be required to assess—under law or charter—or want to know whether the programs they are funding, implementing, voting for, receiving or opposing are producing the promised effect.
Greenhouse gas emissionsGreenhouse gas emissions (abbreviated as GHG emissions) from human activities strengthen the greenhouse effect, contributing to climate change. Carbon dioxide (), from burning fossil fuels such as coal, oil, and natural gas, is one of the most important factors in causing climate change. The largest emitters are China followed by the US, although the United States has higher emissions per capita. The main producers fueling the emissions globally are large oil and gas companies.
AC powerIn an electric circuit, instantaneous power is the time rate of flow of energy past a given point of the circuit. In alternating current circuits, energy storage elements such as inductors and capacitors may result in periodic reversals of the direction of energy flow. Its SI unit is the watt. The portion of instantaneous power that, averaged over a complete cycle of the AC waveform, results in net transfer of energy in one direction is known as instantaneous active power, and its time average is known as active power or real power.
Opera houseAn opera house is a theatre building used for performances of opera. It usually includes a stage, an orchestra pit, audience seating, and backstage facilities for costumes and building sets. While some venues are constructed specifically for operas, other opera houses are part of larger performing arts centers. Indeed, the term opera house is often used as a term of prestige for any large performing-arts center.

Chinese operaTraditional Chinese opera (), or Xiqu, is a form of musical theatre in China with roots going back to the early periods in China. It is an amalgamation of various art forms that existed in ancient China, and evolved gradually over more than a thousand years, reaching its mature form in the 13th century, during the Song dynasty (960–1279). Early forms of Chinese theater are simple, but over time various art forms such as music, song and dance, martial arts, acrobatics, costume and make-up art, as well as literary art forms were incorporated to form traditional Chinese opera.
Emissions tradingEmissions trading is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants. The concept is also known as cap and trade (CAT) or emissions trading scheme (ETS). Carbon emission trading for and other greenhouse gases has been introduced in China, the European Union and other countries as a key tool for climate change mitigation. Other schemes include sulfur dioxide and other pollutants.
