| carbon dioxide (n.) – khí CO2 | David Bayless, a professor of mechanical engineering at Ohio University, has been working with scientists to engineer a device that can grow cyanobacteria (blue-green algae).

| tank (n.) – thùng, két, bể chứa | It is unlikely that drivers would ever want to fill up their tanks entirely with ethanol, which contains only two-thirds of the energy of gasoline, whereas biodiesel is only 2 percent less fuel-efficient than petroleum-based diesel. |
| vehicle (n.) – phương tiện giao thông | The local council imposed a new tax on vehicles travelling in the city during rush hour. |
| carbon neutral (adj.) – trung hòa carbon | The festival this year will be carbon neutral, meaning it will offset the carbon dioxide it emits by purchasing credits that pay for cleaning carbon waste. |

| efficient (adj.) – hiệu quả | People would use a lot less power if they bought household goods that were energy efficient. |
| pressing (adj.) – cấp bách | It is unlikely we will abandon our cars in large enough numbers to resolve this problem, so there is a pressing need to find an alternative fuel. |
| unleaded (adj.) – không chì | Samuel Bowser first invented the petrol pump in 1885 but it wasn’t until 1988 that all new cars manufactured in the UK were required to use unleaded petrol only. |

| discharge (v.) – đổ ra, thải ra | Some logging companies burn large tracts of forest just to facilitate access to one area-a practice that discharges even more carbon dioxide. |
| emit (v.) – thải ra (khí), tỏa ra (mùi) | It’s estimated that for each mile or 1.6 km that a jet flies, half a kilo of CO2 is added to the atmosphere. So a round trip of 10.000 miles would emit about one and a half tonnes of CO2 per passenger. |
