概括
企业气候倡议取得进展,但大多数成员缺乏真正的运营减排. 许多人依靠购买可再生电力,数据验证和可持续性措施需要改进.
科学领域:
- 环境科学环境科学
- 企业的企业可持续发展
- 减缓气候变化减缓气候变化减缓
背景情况:
- 公司的气候倡议,如基于科学的目标和RE100已经显著增长.
- 预先研究表明,这些举措可以推动远远超过国家目标的大幅减排.
- 对其实际进展和附加性的经验评估仍然很少.
研究的目的:
- 评估企业气候倡议的实际进展情况.
- 评估成员如何实现其目标以及其贡献的真正附加性.
- 识别数据稳定性和可持续性措施实施中的差距.
主要方法:
- 按部门和地理区域分类倡议会员资格.
- 使用公共环境数据评估2015-2019年间的进展情况.
- 分析了收入最大的102家成员公司的数据.
主要成果:
- 分析公司的集体范围1和2排放量减少了35.6%.
- 大多数公司都在轨道上或超过了将全球变暖限制在2°C以下的场景.
- 减少集中在少数密集型公司;大多数成员显示有限的运营减排,主要是通过购买可再生电力.
结论:
- 虽然集体排放量有所下降,但大多数公司的进步主要依赖于购买可再生电力,而不是直接减少运营成本.
- 数据验证 (75%低保证) 和可再生电力采购 (71%低影响或未披露) 存在重大差距.
- 需要进一步努力,以提高数据的可靠性,并实施可靠的可持续性措施,以实现可信的气候行动.

Global Climate Change
24.6K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Sustainable Development
13.4K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

What is Climate?
18.7K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Quantifying Work
19.8K
As a system undergoes a change, its internal energy can change, and energy can be transferred from the system to the surroundings, or from the surroundings to the system.

Quantifying Heat

Thermal Energy Microscopically, thermal energy is the kinetic energy associated with the random motion of atoms and molecules. Temperature is a quantitative measure of “hot” or “cold”, which depends on the amount of thermal energy. When the atoms and molecules in an object are moving or vibrating quickly, they have a higher average kinetic energy (KE) (or higher thermal energy), and the object is perceived as “hot”, or it is described as being at a...

The Carbon Cycle
38.7K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.
