Color codes
Hydrogen is often referred to by various colors to indicate its origin (perhaps because gray symbolizes "dirty hydrogen" ).

H2
The International Energy Agency’s (IEA) Net Zero Emissions Scenario for net zero global greenhouse gas emissions sees the direct use of hydrogen accounting for 8% of worldwide aviation energy demand, with synthetic hydrogen-based fuels (not used by hydrogen planes) comprising 25%. The IEA expects hydrogen aircraft to become commercially available from 2035, with half of small and medium-sized passenger aircraft sold to serve short- to mid-haul routes being hydrogen-fuelled by 2050

History and terminology
"For all these reasons, WHO has reformulated the access to clean cooking indicator to measure the “proportion of population primarily using clean fuels and technologies for cooking,” and this has been adopted as part of SDG 7 (“Ensure access to affordable, reliable, sustainable, and modern energy for all”). This reformation automatically increases the cooking access relative to what was reported in previous GTFs. For example, in 2012 the 134 million households estimated as using kerosene were not counted as part of the cooking access deficit, but they would be now. This report recalculates the historical series using the new definition back to 2000, and all results are reported in these terms."

The term "clean cookstove" has often been used without defining what the term means. The World Bank uses a system of six attributes measuring exposure to pollutants, efficiency, affordability, safety, availability, and convenience. Cooking facilities are ranked on a scale of one to five in each attribute.

ISO defines "clean cookstove" as a cookstove that "reduces emissions to an acceptable level when fed with a defined fuel or fuels"

Welcome to Wikipedia from WikiProject Climate Change!
Thanks for coming aboard! We're a group of editors who strive to improve the quality of climate change articles here on Wikipedia. I noticed that you are interested in editing related articles; it's great to have a new editor on board.

Wikipedia is the most requested, published, accessed, and consulted source of information on climate change in every language. Wikipedia is the best choice for education and dissemination of information in general, and also the best path to reach influencers including journalists, policy makers, politicians, and decision makers at all levels. A few things that may be relevant to editing Wikipedia articles are:


 * Feel free to leave us a message at any time on our talk page. If you are interested in joining the project yourself, there is a participant list where you can sign up. Please leave a message on the talk page if you have any problems, suggestions, would like review of an article, need suggestions for articles to edit, or would like some collaboration when editing!
 * For ideas on sources, check out our recommended sources collection.
 * The Wikipedia community includes a wide variety of editors with different interests, skills, and knowledge. We all manage to get along through a lot of discussion that happens under the scenes and through the bold, revert, discuss editing cycle. If you encounter any problems, you can discuss them on an article's talk page or post a message on the talk page. Or for general questions about how Wikipedia works, feel free to ask at the Wikipedia Teahouse.

Feel free to drop a note on my talk page if you have any questions. I wish you all the best!
