# Estimating Carbon Emissions ## Air Travel The most authoritative source for estimated emissions associated with commercial air travel is this calculator from ICAO: For private air travel, emissions are substantially higher and highly dependent on the aircraft flown and number of passengers. ## Personal Annual Emissions Based on widely available statistics for many countries, it is possible for individual consumers to estimate their emissions by filling in details about their lifestyle into a form like these: * General-purpose global calculator: * Official USA EPA calculator for US-based individuals: ## On-Chain Transactions * [carbon.fyi](https://carbon.fyi) is an easy-to-use interface for estimating emission from Ethereum mainnet transactions * NOTE: emissions are approximately 0 since the Merge, only 800 tonnes annually for the entire network, so addresses with no pre-merge transactions will show 0 emissions * KlimaDAO has also developed a Dune query suitable for estimating emissions from an arbitrarily large batch of addresses, based on the same emissions estimate as carbon.fyi here: --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.klimadao.finance/references/estimating-carbon-emissions.md?ask= ``` The question should be specific, self-contained, and written in natural language.
