The data only consider carbon dioxide emissions from the burning of fossil fuels and cement manufacture, but not emissions from land use, land-use change and forestry. [n 2] Over the last 150 years, estimated cumulative emissions from land use and land-use change represent approximately one-third of total cumulative anthropogenic CO 2 emissions ...
Carbon dioxide is the main greenhouse gas resulting from human activities. It accounts for more than half of warming. Methane (CH 4) emissions have almost the same short-term impact. [5] Nitrous oxide (N 2 O) and fluorinated gases (F-gases) play a lesser role in comparison. Emissions of carbon dioxide, methane and nitrous oxide in 2023 were all ...
The government has committed to reducing emissions by 50% of 1990 levels by 2025 and to net zero by 2050. [2] [3] In 2020, the UK set a target of 68% reduction in emissions by 2030 in its commitments in the Paris Agreement. [4] The country phased-out coal power in 2024.
GCSE Bitesize was launched in January 1998, covering seven subjects. For each subject, a one- or two-hour long TV programme would be broadcast overnight in the BBC Learning Zone block, and supporting material was available in books and on the BBC website. At the time, only around 9% of UK households had access to the internet at home. [3]
In 2020, territorial carbon dioxide emissions from the transport sector were 97.2 Mt, 19.6% (23.7 Mt) lower than in 2019, and 22.5% lower than in 1990. In 2020 transport accounted for 29.8% of all territorial carbon dioxide emissions, compared to 33.1% in 2019. The large majority of emissions from transport are from road transport. [18]
Carbon dioxide is often mentioned in the context of its increased influence as a greenhouse gas since the pre-industrial (1750) era. In 2013, the increase in CO 2 was estimated to be responsible for 1.82 W m −2 of the 2.63 W m −2 change in radiative forcing on Earth (about 70%). [48]
The Intergovernmental Panel on Climate Change (IPCC) defines CCS as: "A process in which a relatively pure stream of carbon dioxide (CO 2) from industrial and energy-related sources is separated (captured), conditioned, compressed and transported to a storage location for long-term isolation from the atmosphere."
BBC Online, formerly known as BBCi, is the BBC's online service. It is a large network of websites including such high-profile sites as BBC News and Sport, the on-demand video and radio services branded BBC iPlayer and BBC Sounds, the children's sites CBBC and CBeebies, and learning services such as Bitesize and Own It.
